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

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.

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

In January 2012 the San Onofre nuclear power plant, which provided power to 1.4 million homes in Southern California

SCE went from having 50 percent of its energy production carbon-free in 2011 to 30 percent in 2012,

A century ago, Henry Ford’s first car ran on alcohol, while Rudolf Diesel fired his namesake engine with peanut oil. But both inventors soon discovered that “rock oil,” when slightly refined, held far more bang per gallon than plant fuel, and was cheap to boot. Oil soon left plant fuels in the dust. Only in periods of scarcity—like the OPEC oil embargo of 1973—did the U.S. and other countries turn back to ethanol, mixing it into gasoline to stretch supplies.

The sun transmits energy in the form of electromagnetic radiation. When this radiation is absorbed by the solar cells, a chemical reaction occurs, causing rapid electron movement. Because of the way the cells are manufactured with layers of material with differing atomic structures, the electrons are forced to move in one direction, creating direct current, or DC. It then flows into an inverter which converts the DC into alternating current, or AC, to be usable in your home or business.

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.

Photovoltaic cells are made of special materials called semiconductors such as silicon, which is currently used most commonly. Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely.

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.

Almost all biofuels used today cause more greenhouse gas emissions than conventional fuels if the full emissions costs of producing these “green” fuels are taken into account,

Solar energy is the cleanest and most abundant renewable energy source available, and the U.S. has some of the richest solar resources in the world.
