  • ) systems. This was double the 435 MW installed in 2009 around the U.S.[16] According to a 2011 survey conducted by independent polling firm Kelton Research, nine out of 10 Americans support the use and development of solar technology. Eight out of 10 respondents indicated that "the federal government should support solar manufacturing in the U.S. and should give federal subsidies for solar energy".[17] According to the Energy Information Administration, in 2010, subsidies to the solar power industry amounted to 8.2% ($968 million) of all federal subsidies for electricity generation.[18] Solar Energy Industries Association and GTM Research found that the amount of new solar electric capacity increased in 2012 by 76 percent from 2011, raising the United States’ market share of the world’s installations above 10 percent, up from roughly 5 to 7 percent in the last seven years.

  • Raw or refined plant oil, or recycled greases that have not been processed into biodiesel, are not biodiesel and should be avoided
  • Fats and oils (triglycerides) are much more viscous than biodiesel, and low-level vegetable oil blends can cause long-term engine deposits, ring sticking, lube-oil gelling, and other maintenance problems that can reduce engine life
  • Biodiesel is distributed from the point of production to retail fueling stations by truck, train, or barge.

Wave Energy Pros and Cons - Energy Informative - 0 views

  • Harnessing wave energy comes without the emission of harmful green house gases. This is the main motivation factor behind further development of this way of power generation.
  • Like with most green energy sources, wave power is also renewable. Since this energy source ultimately comes from the heat energy that is emitted from the sun, it will not disappear for some time – in fact, several billion years or as long time it takes for the sun to burn out.
  • The energy density is typically around 30-40 kW for every meter (2.2 feet) of wave along the shore. As we go further into the ocean 100kW for every meter is not uncommon.
  • ...3 more annotations...
  • Waves are hardly interrupted and almost always in motion.
  • This makes generating electricity from wave energy a reasonable reliable energy source
  • It should be mentioned that the amount of energy that is being transported through waves does vary every year and from season to season. On the northern hemisphere, the average value of November and May could be different with a factor of two or more.

Where Geothermal Energy Is Found - Energy Explained, Your Guide To Understanding Energy... - 0 views

  • Most Geothermal Resources Are Near Plate Boundaries The most active geothermal resources are usually found along major plate boundaries where earthquakes and volcanoes are concentrated. Most of the geothermal activity in the world occurs in an area called the Ring of Fire. This area encircles the Pacific Ocean.
  • The ring of fire goes around the edges of the Pacific. The map shows that volcanic activity occurs around the Pacific rim.Source: National Energy Education Development Project (Public Domain) Naturally occurring large areas of hydrothermal resources are called

Geothermal Energy and the Environment - Energy Explained, Your Guide To Understanding E... - 1 views

  • eothermal power plants do not burn fuel to generate electricity, so their emission levels are very low. They release less than 1% of the carbon dioxide emissions of a fossil fuel plant. Geothermal plants use scrubber systems to clean the air of hydrogen sulfide that is naturally found in the steam and hot water.
  • Geothermal plants emit 97% less acid rain-causing sulfur compounds than are emitted by fossil fuel plants. After the steam and water from a geothermal reservoir have been used, they are injected back into the Earth.

  • They may also reduce the amount of electricity generated from fossil fuels and therefore reduce the amount of air pollution, carbon dioxide emissions, and water use of fossil fuel power plants.
  • Modern wind turbines are very large machines, and some people do not like their visual impact on the landscape. A few wind turbines have caught on fire, and some have leaked lubricating fluids, though this is relatively rare. Some people do not like the sound that wind turbine blades make. Some types of wind turbines and wind projects cause bird and bat deaths. These deaths may contribute to declines in species that are also being affected by other human-related impacts. Many birds are killed from collisions with vehicles and buildings, by house cats and hunters, and by pesticides. Their natural habitats may be altered or destroyed by human development and by the changes in the climate that most scientists believe are caused by greenhouse gases emissions from human activities (which wind energy use can help reduce).
  • Making the metals and other materials in wind turbines and the concrete for their foundations requires the use of energy, which may be from fossil fuels.

Wind - Energy Explained, Your Guide To Understanding Energy - Energy Information Admini... - 1 views

  • Wind is simply air in motion. It is caused by the uneven heating of the Earth's surface by the sun. Because the Earth's surface is made of very different types of land and water, it absorbs the sun's heat at different rates.
  • Wind is a renewable energy source because the wind will blow as long as the sun shines.

Solar Homes and Solar Collectors - 0 views

  •    Solar energy is our birthright like the air we breathe or the water we drink. Solar Home Plans and  cost effective   Solar Hot Water Projects  are the gateway into a "Solar Age"  of energy independence. Fossil fuels are no longer necessary to keep the wheels of civilization turning. Build your own solar heating system.  Explore the Strawberry Fields Book Store  for more information. Alternative energies like solar energy will increase in value as fossil fuel prices escalate making energy efficient,  solar houses more valuable. Solar collectors, solar hot water systems, heat storage vaults, photovoltaic electricity, solar panels, and solar greenhouses will soon become the standard rather than the exception to the standard in the near future According to Buckminster Fuller "We have wondered too far from the roots." An energy crisis can only be avoided only if we learn to rely on a diffuse, sustainable resource like the sun. Become part of this green economy and travel on the  Green Train and learn about Solar Rebate Incentives and Cheap Electricity

Information about Biofuel, what is Biofuel, renewable energy solutions, Ethanol uses - 0 views

  • Basically biofuel is produced by using ethanol from naturally grown plant matter which allows for a more sustainable and environmentally friendly earth.
  • Bio fuel is a natural alternative from other fossil fuels and is attained from living or biological material that has just died. Basically biofuel is produced by using ethanol from naturally grown plant matter which allows for a more sustainable and environmentally friendly earth. To assist in the manufacturing of biofuel, the plants and plant-derived materials that contribute to its formation includes corn, corn cob, sugar cane, soybeans, flaxseed, rapeseed, vegetable oils, waste cooking oils, animal fats, tall oil and even cow manure. However, at present the most widely used source of bioeenergy is of course wood.

fuel cell Facts, information, pictures | Encyclopedia.com articles about fuel cell - 0 views

  • Fuel cells convert chemical energy to electrical energy by combining hydrogen from fuel with oxygen from the air. Hydrogen fuel can be supplied in two ways—either directly as pure hydrogen gas or through a "fuel reformer" that converts hydrocarbon fuels such as methanol, natural gas, or gasoline into hydrogen-rich gas. A fuel cell's only emission is water.
