What Is Biomass Electricity And Is It Green?

Wednesday, January 28th, 2009

Jamie Green asked:


In the race to find a sustainable source of alternative energy, many heads are turning towards biomass electricity.  There are many questions being asked, from exactly how the electricity is made and what it is to whether it is truly a green alternative.  While far fewer consumers know about biomass and the potential held within that would be preferred, the word seems to be spreading quickly, adding to the hope that there will be a more significant demand for this unique method of energy production.

Biomass is living and recently dead biological matter, and can include yard clippings, tree branches, and wood chips.  Biomass is typically obtained from harvesting and processing agricultural and forestry crops.  In a process called cogeneration, the biomass is burned, creating steam that turns turbines in order to create electricity.  The steam is then used for secondary processes, from factory use to things such as drying out vegetables, making the entire process remarkably energy efficient.

The United States currently utilizes biomass for approximately 0.5 percent of its electricity generation.  This small percentage of biomass use saves approximately eleven million tons of carbon dioxide emissions per year compared to fossil fuel combustion.  Converting biomass to energy also changes methane or CH4 to carbon dioxide or CO2.  Because methane emissions are far more harmful to the greenhouse gases surrounding the atmosphere, this process is considered a highly valuable tool in the fight against global warming.  Biomass electricity production reduces greenhouse gases at least five times more effectively than other methods of producing electricity, both renewable and nuclear.

One fact that surprises many consumers is that biomass was once the primary source of heat across the globe.  When thinking of what comprises biomass, many people do not realize that firewood is considered a source.  When considering the amount of homes that still implement fireplaces and the cost effectiveness and efficiency that comes with these heat sources, the need for a source of biomass power on a larger scale becomes more obvious.

One place some cities are finally beginning to see as an excellent source of biomass is municipal waste areas.  As landfills are exceeding their capacity, we are left with lots of trash and nowhere to store it.  A great percentage of our waste is able to be used to produce energy, and many cities are starting to see that converting this waste to energy has multiple benefits in that it creates renewable and environmentally friendly energy while also reducing landfill bound waste.

While most sources of energy must start at the top before they will be usable to consumers, there are a variety of options for using biomass to power your home.  New homes can be built to burn wood or other biomass to produce energy.  Homes are still connected to a city grid in case there is a need for more power, and when excess power is created it produces a credit as the electric meter runs backwards.  As the cost of energy rises significantly, more and more homeowners are implementing such systems in their homes, with the global hope that businesses and industries will soon be forced to follow suit.



What are Alternative Fuel Cars?

Steven Magill asked:


is the price of gas rising ever higher each day, but we must also take into consideration the pollution that cars emit and the damage it does to the environment. Those that want to live a greener lifestyle can do so by first finding alternative fuel cars that will be kinder to the global environment and their pockets as well.

The New Science of Alternative Fuel Cars

Alternative fuel cars are being tested at present to ease the dependence on petroleum. An alternative fuel vehicle can be one that produces less pollution or it can focus on sustainable energy sources. This lessens our need to import fuel from the unstable region of the Middle East and also addresses global warming issues that are at the forefront of many governments at this time.

An added bonus in looking into alternative fuel cars in the United States is the Federal tax incentives the government is offering to those citizens that purchase alternative fuel vehicles that qualify according to their standards.

What are Alternative Fuels?

One alternative fuel you may be hearing much about in the news is ethanol. Ethanol is being produced in the U.S. and it comes from crops such as corn. It is said to produce less emission and greenhouse gases than the conventional fuel sources we now use. There is much debate over the use of ethanol as it takes energy in order to produce it and the facts are still up in the air about whether it is truly worth the cost and effort to produce.

Biodiesel is another popular alternative fuel source. It comes from animal fat and vegetable oil. It is said to produce less pollution than conventional diesel fuel that is based on petroleum. Willy Nelson, the famous crooner of country ballads is a huge advocate of using biodiesel for alternative fuel cars.

Natural gas is said to generate less pollution into the air as well as a smaller amount of greenhouse gases. There are not many alternative fuel cars that run on natural gas at present but with the leaps and bounds in science, it is only a matter of time before this may be a viable fossil fuel alternative to petroleum.

Hydrogen is a versatile source for alternative fuel cars. It can be produced from a number of fossil fuel sources such as nuclear power, coal and other sources of renewable energies. Hydropower fuel cell cars are powered by hydrogen and do not let off any harmful pollutants into the air.

What You Can Do

The average consumer can find alternative fuel cars in a variety of ways. Doing the proper research on the best alternative fuel cars for the money they have to spend is one of the best ways to lessen our dependence on foreign oil and to make positive changes that will address global warming and climate change. It takes a village to raise a child the old saying goes, but it also takes that same village to make changes in the way we handle our fuel needs.

Analysis of Governance Issues in the Energy Market in Sierra Leone

Sunday, January 25th, 2009

Kenday S. Kamara asked:


Context of Sierra Leone’s Energy Policy

In December 2004, a UNECA sponsored study conducted by CEMMATS Group Ltd., a local consulting firm, involved various stakeholders in the sector to formulate an energy policy. The CEMMAT’s energy agenda for Sierra Leone in terms of policy and management represents an important set of tools that basically encapsulates a multi-disciplinary structure bringing together sectors of the energy community – the Ministry of Energy and Power (MEP), the Ministry of Trade and Industry, the Ministry of Finance, the Ministry of Agriculture and Food Security (MAFS), Presidential Petroleum Commission, and the Ministry of Mineral Resources (MMR). These line Ministries of relevance to the energy agenda, where their various roles are being specified, have dominated the development of the country’s energy policy. The basic premise of this multi-disciplinary structure is that it is crucial for the effective and efficient coordination of the management of the country’s indigenous energy resources.  Nonetheless, it sounds as though it would be impossible to coordinate these so many organizations in a country with a history of corruption and mismanagement. But it is not unusual to have various Ministries working in coordination to achieve national development objectives. Besides, the specific tasks and methods of operation that influence the ability of these Ministries to create the enabling environment for private interests to ably conduct value added commercial activities with the country’s energy resources are defined.

This structure, for instance, places the Ministry of Energy Power in a central position as the governmental authority responsible for the electricity and water sectors and its mandates includes sector policy formulation, sector planning and coordination. The Ministry is supported by the Office of the Permanent Secretary, the Water Supply Division (WSD), the Radiation Protection Unit, and the National Energy & Water Policy, Planning, and Coordination Unit (NEWPPCU). Under the Ministry’s purview as well is handling matters related to electrical power supply, including that from hydroelectric schemes and, nominally renewable energy matters related to solar and wind energy through the utilities companies - the National Power Authority (NPA)/Bo-Kenema Power Services (BKPS); the Guma Valley Water Company (GVWC); the Sierra Leone Water Company (SALWACO); and the Bumbuna Hydroelectric Project (BHP).

The roles of other Ministries are limited to handling petroleum marketing sales under the purview of the Ministry of Trade and Industry and the Ministry of Finance; biomass issues (plant and animal-derived matter) especially fuel wood handled by the Ministry of Agriculture and Food Security (MAFS); and the extraction of minerals, including energy related minerals like coal and ore dealt with by the Ministry of Mineral Resources (MMR).

The energy sector maintains this organizational structure to develop and implement inter-disciplinary energy-related policies. The functions of these various Ministries and other authorities as they relate to their responsibilities for various energy resources are outlined in the relevant Acts of Parliament (accessible via government gazettes) and pertinent regulations. Some of the relevant Acts include the NPA Act, 1982; the NPA (Amendment) Act, 2005; Forestry Act, 1998; and the Petroleum Act, 2002. There is also the draft energy policy document prepared by CEMMATS which is yet to be adopted. The policy document has been formulated in the context of standard economic, social and environmental policies; mindful as well of the nature and linkages of the energy sector with other sectors; and the international and regional linkages of the sector.

Furthermore, finding efficiency and economic value, from an international investor’s perspective, within a system of such complicated oversight is made less complicated with “the Sierra Leone Export Development and Investment Corporation (SLEDIC), a statutory body established by section 2 of the SLEDIC Act, 1993, with the primary objective of facilitating the registration of business enterprises; assisting investors in obtaining permits, licenses, certificates or clearances, as the case may be, needed for the commencement of business; providing information to potential investors on matters relating to investment; and assisting potential investors in identifying joint venture partners in Sierra Leone”. The priority investment areas SLEDIC is promoting thus include:

·         Energy and power sector (independent power providers)

·         Agriculture and Agro-Processing

·         Mining Sector (Kimberlite Mining)

·         Petroleum Exploration and Exploitation

·         Privatization of state-owned enterprises

·         Establishment and development of Export Processing Zone (EPZ)

·         Infrastructure (Railway, Roads, Telecommunication, Water Supply) etc.

Energy Outlook

Sierra Leone is far down the under-exploited curve in terms of its energy endowment. The fact is, there are untapped energy resources, that the nation needs these resources, and that the energy industry can coordinate the exploitation of these resources with less environmental impact. Sierra Leone’s indigenous energy resources of a renewable nature which include biomass, solar, wind and hydropower has the potential to provide opportunities for Sierra Leonean households at all levels. The country’s biomass volume is about 656,000 tons of crop wastes. It has an annual energy potential of 2,700 GWh that can be exploited for cooking, lighting and some power applications. A commercially viable biomass supply therefore exists but discussion about biomass facilities has not attracted much discussion and promotion by the government. The Government of Sierra Leone has not seriously addressed energy, fuel and water efficiency in all sectors of economic activity, and has not industrialized capacities for optimal use of natural resources for sustainable biomass (unicellular-energy crops-residues-waste). But notwithstanding its lack of interest in bio-prospecting, the government is not going to stand in the way if traditional biomass firms in Europe and the United States are interested in developing this potential in Sierra Leone.

The country also has a solar radiation potential of between 1460 kWh/m2/yr and 1800 kWh/m2/yr annually. This can be exploited for lighting and water pumping, among other applications. These resources provide an intriguing glimpse of a nation that might have had a sustainable supply of power and profitable exploitation of its promising energy resources, had energy efficiency remained a core value of the country after independence. The goal for sustained economic growth and development should be seen in terms of managing the full utilization of these resources.

The hydro potential in the country has also been an epic story. The network of rivers in the country provides an opportunity for hydroelectricity with over 21 sites already identified as capable of producing potential hydro power. The conservatively estimated output at 1,200MW, recorded in the 1996 Power Sector Master Plan by Lahmeyer International, is necessitated by the country’s extensive network of rivers and tributaries. The completion of the current Bumbuna project (Phase I capacity 50 MW, total capacity 275 MW) and the envisaged Bekongor project (Bekongor III capacity 85 MW, total capacity 200 MW) – two of the many large projects that are economically exploitable – is good for the development of the country and for Sierra Leone jobs. But the political will has to be there to get the Bumbuna project to 100% completion. There is also the need to create the supporting environment for private companies to invest in mini-hydro, or “run-of-the-river” hydro power stations. The Bumbuna project, which “can eventually become the backbone of a national grid, has the potential to make a substantial positive impact on the national electricity supply” (CEMMAT Policy Document, 2004).

In terms of power infrastructure, the national power stations in the major cities and towns, which are really a collection of regional power stations, needs both new infrastructure and new ideas. “Most of the provincial stations and networks are in a state of total disrepair.  The cost required to get them back to their pre-1994 levels is estimated at Euro 13 million” (CEMMAT Policy Document, 2004). The Bo-Kenema Power Services (BKPS) which has a mixed hydro-thermal operation capacities of 5MW and 4MW at Bo and Dodo (Kenema) respectively faces the same management problems with its commercial operations as NPA. Rural electricity supply is non-existent. A new electricity policy is overdue, though the specifics matter, the CEMMATS draft on energy policy is instructive in this respect.

There are fairly quantified fossil fuels (hydrocarbons) with commercial value in Sierra Leone. These include significant ignite deposits and crude oil which have not been exploited.  These fossil resources have not been properly assessed to determine their potential value for practical and profitable exploration.  Though previous administrations had offered to sell concessions for prospecting for oil and other valuable mineral resources in the country, there had always been institutional secrecy surrounding the potential existence of oil as a source of wealth creation for Sierra Leone. “The location, extent, and quality of the find have remained a subject of uninformed speculation, intense curiosity, and often-wild conjecture.  It is a state of affairs to which both official secrecy and the lack of transparency in the conduct of public affairs in Sierra Leone have largely contributed” (Focus Sierra Leone). The Petroleum Resources Unit, under the authority of the current President and headed by a Director–General continues to oversee the possibilities of exploration of these petroleum resources especially with European and/or American investment companies. It is the position of the government of President Koroma that whatever economic benefits that are attached to the exploration of fossil fuels should be in the interest of national development.

Good governance groups and the masses roundly criticized previous administrations for inadequate measures on energy supplies in the country. Previous administrations failed to put real dollars in the energy sector where they would have had a direct impact on advancing adequate and sustainable supply of electricity in the country. More opportunities could also have been created to effectively support other forms of renewable energy.  All in all, the energy potential is undoubtedly great. But more emphasis has to be placed on a more investment-friendly energy policy, particularly on opening the energy market to huge capital investments and broadening incentives for investment.  The reality is, there is the need (the market) for more domestic energy and more imported energy.

The best talents in the energy industry have to be accessed and retained to coordinate and efficiently manage an A+ energy program for Sierra Leone. The country needs a balance of vision in the form of a grand strategy to curtail the difficulties the country faces with commercial energy supplies, particularly electricity supply. Attainable short-, medium-, and long-term steps to get the country there have to be practically laid out. And while the grand strategy is being put in place, the government should not fail to connect energy to climate change. Global warming has proved to be as horrendous a global challenge as the War on Terror.

Capital Investment and the Energy Market

Certainly, one major factor for successful energy policy and management is financial resources. But the energy sector in Sierra Leone struggles with limited budgets and inadequate legislation that has not allowed for the growth of the energy sector, let alone provide a sustainable supply of electricity to the urban and rural consumers. Clearly, over the years, previous administrations were not in a position where they could afford to wisely invest or even create an enabling environment for foreign investments in the energy sector simply because of widespread corruption in public administration. The National Power Authority, for instance, has unpaid debts of Le23.4 billion and unpaid customer bills of Le16.2 billion as well as fuel bills to petroleum companies of Le8 billion. The utility authority also has a defective transmission and distribution system with 35% technical losses; and an electricity drop from 28MW from five diesel engines to 6MW from one diesel engine among other problems.

Other logistical challenges include the procurement, storage and transportation of petroleum products. “Sierra Leone is almost entirely dependent on imports for all its petroleum needs and machinery as well as spare parts” (CEMMAT Policy Document, 2004). Petroleum products are transported by road using tankers. The poor state of the roads exacerbates several problems with transportation.

In addition, increasing funds devoted to energy supply has only helped relatively little, given the impoverished state of the country. Sierra Leone does have a smaller Gross National Product (GNP) with amounts allocated to the sector way considerably less than investments made by countries with larger GNPs. However, it is not only the total amount of money from the GNP that counts, but also how that GNP allocation is supplemented by foreign direct investments and how such investments in the sector are spent.

Besides, it is possible for the government to find funds to support its energy sector. In 2001, for instance, the World Bank Group funds estimated at US$7.5 million were made available to the government of Sierra Leone under former President Ahmed Tejan Kabbah to buy a new engine to increase electricity capacity. But a used and poorly rebuilt 7.5 megawatts diesel engine was acquired.

And quite recently, “coinciding with the visit of the President of Sierra Leone to the UK, Douglas Alexander, the Secretary of State for International Development announced two programs of assistance to Sierra Leone totaling £36 million [– with] £20 million to support the building up of energy sector in Sierra Leone [that] should provide a sustainable electricity supply to the one million residents of Freetown and provide lighting and power for health centers, water pumping stations, colleges and police stations” (Press Release).

In view of all these possibilities, a perennial issue that must be addressed in order to build a sustainable capacity in the energy sector is a change of mentality in society and among decision-makers. “No capacity-building initiatives will succeed if governments and the public are not determined to change the situation” (Embo Reports).  Now there is hope with the new democratic dispensation. On assumption of office, President Koroma made a pronouncement that energy is his topmost priority. To a large extent, Koroma’s Government is therefore supportive of capital investment in the energy sector.  May be, what the Koroma administration also needs to do is to support a clear energy sector initiative in capacity building by addressing the problem of proper allocation of funds and managing a sustainable energy supply mechanism.

The strategy already being pursued by the Koroma administration which is the actualization of an “energy stimulus plan” for Freetown and the entire country is commendable. A Presidential Emergency Task Force has been created to oversee the increase of electricity capacity in the country. Measures have also been taken to involve private interests in the energy sector. Two 48MW independent power producer (IPP) contracts with the Nigerian investment company Income Electrix and the US investment company DELAMORE have recently been signed by the Sierra Leone Government to add to the capacity of electricity supply. Income Electrix has already shipped equipment and mobilizing to commission a 10MW generator at Black Hall Road to supply electricity to the east part of Freetown. A Sierra Leone Government partnership with the Nigerian company Income Electrix is a good investment strategy for both countries.  Even though Nigeria’s focus on being a leading economy via its oil industry has its challenges, Nigeria’s share of global oil reserves is quite impressive. The challenge for Nigeria’s oil exploitation is not a scarcity of world-scale oil reservoirs, rather it is connecting those oil reserves to long-term customer commitments and the capital required to build oil refineries or multi-thousand mile pipelines. Nigeria’s oil reserves create a terrific opportunity to align and integrate with Africa, rather than holding Africa hostage to scarcity. A large part of any diplomacy with Nigeria should focus on helping Nigeria to see the benefits of such a relationship.

By and large, Sierra Leone’s energy “industry shows the potential to contribute as much as Le 46 billion (approximately US$ 16 million) annually to government revenue in terms of Excise Tax and Road Users Tax” (CEMMAT Policy Document, 2004). The potential is remarkable even when the demand for energy in the industrial and commercial sectors is mainly met by self auto-generation which has negative economic consequences.  Michael Conteh, resident technical consultant who is playing a coordinating role in the Ministry of Energy and Power and its relations to the other Ministries and utility companies as well as monitoring the power system and providing technical advice to the ministry has spoken quite reassuringly about the under-exploited state of Sierra Leone’s vast energy potential. According to his expert knowledge of the energy sector, “currently, there are no programs in the country for alternative energies. Sierra Leone’s energy mix is very limited. Apart from cooking that is about 95% dependent on biomass, Sierra Leone is almost 100% dependent on imported petroleum products and electricity for all its energy needs.” Again, restoring the operations of the Sierra Leone Petroleum Refinery Corporation (SLPRC) which has a distillation potential capacity of 700,000 metric tons has the possibilities of generating more revenue for the government. The corporation requires healthy investment to sustain its distillation capacity. Bringing together the five petroleum major foreign oil and oil services companies operating in the country namely Mobil, National Petroleum Company (NP), Safecon, Unipetrol and Leonoil, and/or other investors within the SLPRC is critical to revamp the refinery’s operations and to invigorate the market’s future potential and stimulating the rise of alternatives.

Royalties Structure and the Costs of Corruption

The structure of energy royalties is spelt out in the Local Government Act, 2004 (Local Government Act, 2004). But Sierra Leone’s energy sector, with its multifaceted mix of public and private actors, has a bleak history of weak monitoring, low transparency, and inadequate civil service pay and benefits; and incentives for illicit gain are rife. The sector has the potential to generate significant cash transactions compared with other services and infrastructure sectors such as water and sanitation or use of roads. But the common forms of corruption plaguing the sector involves petty corruption which is prevalent at the interface with customers when bribes are paid to or demanded by meter readers or safety inspectors and illicit sale of fuel oils.  There are also many illegal connections by low-income as well as high-income households and commercial establishments. The aggregate impact of “petty corruption” may be far from petty because losses may amount to more than $10 million each year. Inadequate revenue collection and other corrupt practices lead to deteriorating service with frequent blackouts and supply interruptions.

The viability of the energy sector thus involves a strategic study of the complex systems of sustainable power supply and revenue collection. Governments can act decisively to deal with corruption in the energy sector—most involving privatization, competition, more transparent rules, and more disclosure. Reforms in the energy sector can be in the form of selling specific activities such as the energy distribution system using prepaid meters to strategic investors with a proven track record and a long-term interest in the business. The prepaid meter system currently piloted in Freetown has the potential to increase revenue collection and reduce corruption in the sector. About 2000 prepaid meters are currently in use. The government has contracted the Chinese investment company, the Sierra Leone Gouji Investment and Development, Ltd. for supply of 100,000 prepaid meters. “Chinese influence in the investment climate is growing steadily [superseding European and US investment] to the extent that a Chinese Chamber of Commerce and Industry was launched in 2005. The government has been supportive of Chinese investment initiatives, apparently because of many years of Chinese government assistance to Sierra Leone. The Bintumani Hotel, ravaged by invading rebels in 1999, is on lease for 25 years to Beijing Construction. The Chinese have transformed a former home for the displaced, the National Workshop, into a showpiece tractor-assembly plant [from which the Gouji prepaid meters being piloted in Freetown are also distributed]” (African Review of Business and Technology). Nevertheless, a new Sierra Leone under President Koroma is now open for business and the reforms in the energy sector the new administration is advancing include as well more transparent market rules and coordinating an independent regulatory body with more presidential oversight to oversee the efficient management of a more creative energy sector.

Opportunities

Efforts to address energy supply and coordination challenges should be placed in a large policy framework that addresses other social issues. More notably, such strategies should be part of policies designed to use modern and efficient energy services to achieve sustainable development goals.  Adequate resources ought to be made available for investment in oil exploration and development activities and there has to be investor-friendly legal and regulatory framework to attract oil exploration companies. There are issues of supply and storage limitations for various petroleum products and the necessity to re-launch refining operation in the country. And when clear and unified standards for operating retail outlets are also put in place, access to modern and efficient energy resources is ensured.

Guiding national research and development efforts to focus on these challenges will require extensive international cooperation, increases in energy sector funding and incentives for private enterprises. It will also take the creation of an atmosphere that is tolerant to the use of emerging technologies in implementing sustainable energy sector goals. Having a solid energy policy can be viewed as strategic to the country’s national interests.

Wind Power

Thursday, January 22nd, 2009
hydro fuel
David Tanguay asked:


With the way the energy crisis is growing, soon the fossil fuels that we rely on will be gone or so overpriced, that very few people will be able to afford it. Researchers have been creating new and innovating ways to create energy out of the natural resources that Mother Nature provides. Even though the wind has been a source of power for hundreds of years, it is not until recent decades that it was considered on a large scale.



There are many different types of natural resources that researchers have found promising, however, wind power is the most promising and least expensive renewable power source. There is however a downside to wind power; its variable nature because wind doesn’t always blow researchers must determine the effects it will have, however, wind power has been determined to be stable, because its cost does not fluctuate with the price of fuel.

Wind power is the conversion of wind energy into useful form, such as electricity, using wind turbines. It is used in large-scale wind farms and for national electrical grids as well as in small individual turbines for providing electricity to rural residences where traditional power is not offered.

Wind power is versatile when air moves, causing wind, it has kinetic energy—the energy created whenever mass is in motion. It is especially helpful here in the winter to capture both the ferocious and gentle mountain winds during the times of least sunlight and highest power use.

Wind Power is clean and renewable type of energy, and should be considered an important component of any long-term energy strategy. This is because wind power generation uses a natural and virtually inexhaustible source of power, (the wind) to produce electricity.

Wind power is an affordable, efficient and inexhaustible source of electricity. It is set to become an important means of generating electricity worldwide. Wind power has become the world’s fastest growing energy source, It a viable, robust, fast-growing industry. Wind power is growing partly as a result of technology improvements and cost reductions and partly in response to state and federal laws and incentives.

Wind power is by far the renewable source with the largest growth in worldwide capacity during the last decade. Wind power is now a major option for new, utility-scale power generation. It does not even compete with the prices of fossil fuels, which are continually rising on a daily basis.



Passive and Proud: Green Energy Ideas for your Home

Thursday, January 22nd, 2009
green energy
Carolyn Gjerde Tu asked:


Solar energy comes from the sun. A biology class will tell you that in addition to affecting climate and weather, sunlight provides the energy that sustains most life on earth. It also can be harnessed to provide heating, lighting and electricity. Solar power has become a hot topic lately, but this technology is nothing new – Native Americans, people in China and even the early Greeks have historically turned their buildings to the sun for heat.

These early architects were using what is known as passive solar energy. This technique makes the best use of regular building materials to trap heat with no additional mechanical equipment used. Floors, windows and roofs play a role in attracting (or deflecting) the sun’s rays.

There are a number of ways to take advantage of solar radiation, starting with the house’s placement. Having the house face the equator (we’ll assume we’re in the Northern Hemisphere, thus the house should face south) means that it gets the day’s sunlight. Window orientation is also important – for optimal efficiency, most windows should point within 30 degrees of due south. Maintaining a small percentage of north facing windows will ensure that your home is comfortable year round (and not cooking in the summer).

Rock or stone tile floors and brick walls will absorb the solar radiation and continue to give off heat after the sun is gone. While common windows allow heat to escape, special windows with low-e coating, multiple panes, inert gas fill, and/or insulated frames can reduce heat loss 50 to 75 per cent. By sealing your building envelope and insulating well, you will ensure that the heat stays in the house. It can then be distributed through the house using a regular ceiling fan.

Direct sunlight is not the only important light to think of when considering energy use. By using overall daylight to light a space you can cut down the need for electrical lighting and the heat that’s created by it. Artificial lighting has only been the main source of illumination since the 20th century. And using natural light may have added benefits for your physical and mental health. In addition to windows, daylighting makes use of skylights, light pipes (also known as light tubes), atriums, and light shelves to illuminate the interior. This is best considered when building, but with a few small renos your house can be much brighter, naturally!

Passive cooling is another way to cut your bills and become more energy efficient. This is especially useful in warmer climates, where air conditioning can be a major power consumer. Passive cooling refers to using things for shading, to absorb the heat, and goes hand in hand with passive solar energy. It can be accomplished using exterior landscaping choices – trees and other vegetation – or interior/exterior building options, such as shades, blinds or special glazing on windows.

Whether you are building a new home, looking at doing some renovations or just want to cut your energy bill, passive solar energy and cooling techniques are an easy way to incorporated green ideas into your home. With the rising interest in environmental issues, they make an excellent selling feature and they’ll save you money.



This is the Reason Why Biodiesel Fuels are so Economical

biodiesel
Muna wa Wanjiru asked:


Biodiesel is known as an alternative fuel for burning. Biodiesel fuel comes from 100% renewable resources. Biodiesel can be used in vehicle, while mixing it with petroleum to produce biodiesel blend. Biodiesel is biodegradable. Biodiesel fuel produces about 60% less net lifecycle carbon dioxide emission, as compare to it is itself produced from atmospheric carbon dioxide. It is being watched that smog forming hydrocarbon emission are 35% greater and the Nitorgen Oxide emission are also greater.

Diesel engine used pure biodiesel fuel. Biodiesel is very safe to use, it is non toxic. Biodiesel is not alternative for vegetable oil. It can be used in its unaltered form in diesel engines. Only vegetables oil fuels must be changed and which is being used in combustion or ignition engines. It makes biodiesel one of the easiest alternative fuels to use. It is being get used in farm equipment.

Biodiesel fuel is made through process known as Tranesterfication. In this process, glycerin is taken out from vegetable oil or fat. Byproducts like methyl and glycerin being left in between the process. Biodiesel is free from sulfur and other aromatic which generally used to occur in traditional fuels. This unique quality of Biodiesel makes it different from other alternative. Biodiesel has passed all the health cautious test, means it is taken care that it should not affect human being. It is legally registered under environment protection agency. It can be legally sold and distributed in any part of world, while other alternative fuels cannot be sold legally.

Biodiesel is very much economical because it does not require costly raw material. Whatever the raw material it requires comes from plants and biodegradable, so it does not involves much cost. Now days it is rapidly becoming available to the general public. It is available at selected places in country or it can be directly bought from producer. Now its demands getting high, everybody is realizing benefit of biodegradable. It is a very much cheapest way to get biodiesel fuel is to make Biodiesel at home on yourself.

There are some vehicle manufacturers; who are positive about the use of biodiesel. For example, lower engine wear is cited as one of the fuels benefits. Biodiesel is very good than other standard diesel fuel. It used to clean the engine, also removes deposited dust in the fuel line. It is recommended by car manufacturer to change the engine after few months after switching to biodiesel. There are manufacturers that have released list of cars that run of Biodiesel.

Biodiesel is being use as a heating fuel, also in domestic and commercial boilers. There are some existing boilers that are needed to convert to biodiesel, but overall, it does not take much effort or cost to convert to biodiesel.

Note B100 should not be burned in home heaters. And biodiesel is generally more expensive to purchase than any other petroleum diesel, but this difference diminish due to economy. In Germany Biodiesel is cheaper than normal diesel at gas station.



Finding Safer Alternative Energy - Reasons For Its Urgency

Abhishek Agarwal asked:


Our country reels from energy-related problems. The price of gasoline continues to rise. More threats come from the unpredictable economic and political conditions in the Middle East, Iraq, Iran and other countries. If anything, these problems have indicated the extent of dependence of the United States economy on imported oil.

The need to chart new directions on the matter of energy production and supply has become unavoidable for Americans. We need to cut our dependence on imported oil and find viable alternative energy sources. Experts contend that the time for relatively cheap fuel is over, and that we must be ready to pay for its escalating cost unless we succeed in developing cost-effective alternative energy sources. With our technologically-advanced and energy-dependent society, the need for fresh technologically and financially viable alternative energy cannot be avoided.

The environmentalists add their voices to the call for a swift to alternative fuel due to damages inflicted on the environment by petroleum-generated power. Globan warming, water and air pollution have been identified as some of the many environmental risks we expose ourselves to from extensive use of fossil fuel.

Nevertheless, we must also exercise caution in developing alternative energy. Coal, for example, is not inspiring. It is dirty, dangerous to extract, and is also harmful to the environment. Surely, there must be other alternative sources of energy that are safer to process and more environment-friendly, and to which we must turn our primary focus.

Other countries are likewise hard pressed to pursue an alternative energy agenda. It can be assumed that they also contribute to the worsening global climate, and the responsibility for addressing the problem needs to be shared by all. European countries and the United States have made initial advances in the search for alternative energy towards not only reducing their dependence on fossil fuel but also on cleaning up the environment.

The developing countries need to follow our lead in collecting relevant research data and developing alternative energy technologies. The level of government and private research and development collaboration in this field augurs well for strengthening our technological edge. Added benefits thus await from bright prospects of marketing these technologies to other countries.

Other alternative sources of energy that continue to merit further investigation are hydro-electric technology, bio-fuels from trees and beans, natural gas, atomic energy plants, hydrogen cells, and solar energy. Currently getting extra attention from experts is determining the overall viability of wind and solar energy, as well as of generating electricity with hydrogen.

Expectations are high that more sources of better quality alternative energy can be found and put in operation while research and development in this field continues. By then we can look forward to ride our cars and sustain our technologically advanced societies with less fear of further damaging our environment.



The Various Advantages of Producing Algae Biodiesel

Muna wa Wanjiru asked:


Algae is a major renewable fuel which can be used to manufacture Biodiesel. One of the companies in New Zealand successfully developed a system for using sewage waste as a substrate for algae and then it produce bio-diesel. An alga is considered as the highest yield feedstock for biodiesel that can produce more enough oil compared to soybeans when grew in an acre.

Actual Biomass algae produced from field trials, which is conducted during the NREL’s aquatic species program. It is being converted using the actual oil content of the algae species grown in the specific program.

There are various advantages of producing biodiesel from algae, which include rapid growth of the plant. Using Algae Biodiesel gives high per acre yield. Algae biodiesel does not used to contain sulfur, toxic materials and it is highly biodegradable. There are some species, which are ideally suited for algae biodiesel production, because their high oil contents in some species.

Algae used to develop from small, singled celled organisms to cellular organisms, some algae have complex distinguished form. Algae can be easily seen at places like damp, bodies of water. Algae are common in terrestrial as well as aquatic environments. Like any other plants algae require three elements to spring up sunlight, carbon-di-oxide and water. Plant algae and some other bacteria convert sunlight to chemical energy, which process call as photosynthesis. Algae used to contain 2% and 40% of lipids or oils by weight. If algae have greater oil, it may results in lower yield annual food crops such as soybeans. Currently only 0.3% of the land of the US, it is getting utilized to produce enough biodiesel.

Species of algae with up to 50% oil content have conclude that only 28000km land getting used to produce biodiesel. Unused desert land could be used for effective growing of algae.

Following is the productions which obtained in an entire year. In the winter months algae productivity used to drop.

The Enhance Biofuels and Technology generate algae process which combines a bioreactor with an open pond. Here both using waste co2 from coal fired power plant flue gases as a fertilizer. Biodiesel and ethanol can be used an alternative fuel and also it is being sold.

GreenFuel Technology, where emissions to Biofuels process, photosynthesis which grows algae, it capture CO2 and it produce high energy biomass. The algae can be economically converted to solid fuel, methane or liquid transportation fuels like biodiesel and ethanol.



Making Biodiesel at Home is Easier Then You May Think

Andrew Bicknell asked:


As the price of gas continues to rise and our reliance on it becomes greater a small group of people have begun making biodiesel fuel at home as a way to free them selves of the energy crunch that is looming on the horizon. As an alternative fuel source it is hard to beat the ease with which it can be made and its positive impact on the environment.

You really only need two things to make biodiesel: A supply of vegetable oil and a biodiesel processor.

The vegetable oil can be fresh or virgin oil made from soybeans, corn, mustard, flaxseed, and sunflower oil. These are all renewable resources that are grown on farms all across the country. You can also use vegetable oil that has already been used. A great many biodiesel producers great their raw material from restaurant grease dumpsters as most restaurants are only to happy to get rid of the stuff.

There is also ongoing research into using sewage grow algae which is then used in the refining process. Animal fats like tallow and lard are also being used as a raw material for biodiesel production.

All this oil, fat, and grease will need to be processed in a specialized processor which removes any contaminates before it refines the oil into biodiesel fuel. Most processors are not that large and can easily set up in a shed in your backyard. You can purchase them pre-made from any number of internet sites and have it shipped to your front door or you can buy a kit and assemble it yourself. You can also build one yourself using materials found locally. There are plans for doing this along with material lists that can be found on the internet.

Which ever route you choose getting your processor set up at home is not that difficult. Follow the instructions closely and heed all the safety precautions before you begin to process your biodiesel. You are refining a fuel oil which requires high temperatures so there is a risk of burns if you follow the proper procedures.

If you are unsure if making biodiesel is something you want to do you might try finding someone close by who is already making it. Most people who refine this alternative fuel are more then willing to share their knowledge because that’s the best way to advertise its benefits. Chances are they will walk you through the whole process, letting you get a hands on feel for what is involved.

Once you get the hang of it making biodiesel at home is a great way to cut your reliance on the big oil companies for your energy needs. There may be some up front investment to buy the processing unit but once you get rolling you will save considerable sums of money over the life your biodiesel processor.
