The short answer to this question is that Geothermal Energy is a type of renewable energy that is generated and stored within the Earth.

with $25 million set aside for low-income customers. An additional $100.8 million will be used to swap out water heaters powered by electricity.

NATIONALHawaii sets 'breakthrough' framework for new solar power

Technological developments are continually lowering the material and component cost of fuel cells and production is being ramped up and automated, allowing economies of scale to be realised.

pollution spewing from a typical coal plant

3,700,000 tons of carbon dioxide (CO2), the primary human cause of global warming--as much CO2 as cutting down 161 million trees.

sulphur dioxide (SO2), which causes acid rain

Solar energy is good for the planet because it is a clean way to produce things we need every day. It doesnt cause pollution because it is nature's own energy and is a 100% renewable resource.

It is believed that the first geothermal energy use in industry was during the late 18th century near Pisa, Italy. This history of geothermal shows energy been used to extract boric acid from the Larderello Fields through the use of steam

Wind machines were used in Persia as early as 200 B.C

The first windmill for electricity production in the United States was built in Cleveland, Ohio by Charles F Brush in 1888, and in 1908 there were 72 wind-driven electric generators from 5 kW to 25 kW.

The first utility grid-connected wind turbine operated in the UK was built by the John Brown Company in 1954

The BLM manages 20.6 million acres of public lands with wind potential. The BLM has authorized 39 wind energy development projects, including connected-action projects that include electric transmission support authorizations, with a total approved capacity of 5,557 megawatts, enough to supply the power needs of over 1.5 million homes. 

For more than a decade, wind energy has been the fastest growing energy technology worldwide, achieving an annual growth rate of over 30%. In the United States, the current total installed capacity is over 60,000 megawatts of wind projects.

solar energy is environmentally safe and does not contribute to pollution, acid rain, global warming, or smog. it is very dependable and lasts as long as the sun does-a couple billion years.

owa ranks 2nd in the nation for wind energy production as there are almost 2,900 utility scale wind turbines in Iowa.  This creates enough electricity to power 1,000,000 homes. Minnesota is fourth in the nation for wind energy production and Wisconsin is 19th.

Biofuelwatch has released a new report, ‘Sustainable Biomass: A Modern Myth’. It explores the certification companies certifying biomass as sustainable, the UK government’s proposed sustainability criteria for biomass, and developer’s ‘promises’ to source sustainable biomass.

Somewhat surprisingly, the hot air that carries the heat from the earth at geothermal sites also contains carbon dioxide, CO2, the Greenhouse Gas that sends anti-technologists into a frenzy.  The suite of 20 geothermal sites from which Southern California Electric is obligated to buy electricity produces 730 tonnes of CO2 for every gigawatt-hour (GWh) of electricity produced.  Across the spectrum of all natural-gas power plants in the US, the average CO2 production is 519 tonnes per GWh.  That is, the geothermal power plants, which burn no fossil fuels whatsoever, produce 41% more CO2 than the run-of-the-mill natural gas power plant for the same amount of electrical energy produced.

Hazardous chemicals are used in the manufacture of solar cells, creating environmental considerations in their manufacture and, in some cases, in their eventual disposal. Solar cell manufacturers minimize their use of these chemicals, recycle them when possible, and release a minimum of pollutants to the environment.
