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

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.

How is solar energy converted into electrical energy - 0 views

  • Solar energy is very easyto change to electric energy. All you have to do is to take a solar cell. Put it in sunlight or other such source of light. It will use this light energy and will convert it into electric energy.

How Long Has Solar Power Been Around? | eHow - 1 views

  • August Mouchout is credited with the creation of the first active solar motor. In 1861, he developed a steam engine fueled completely by the sun.

Where Does Geothermal Energy Come From - 0 views

  • bounadaries and faults are cracks in the Earth’s crust where magma rises near or to the surface. Geothermal plants take advantage of this fact using water heated by this volcanic activity to produce electric power.
  • The best part is that it is clean energy. There is no way it can produce pollution that can harm the environment

Hydrogen's Dirty Secret | Mother Jones - 0 views

  •  
    "Such a system, experts say, would effectively eliminate most of the benefits offered by hydrogen. Although the fuel-cell cars themselves may emit nothing but water vapor, the process of producing the fuel cells from hydrocarbons will continue America's dependence on fossil fuels and leave behind carbon dioxide, the primary cause of global warming."

Geothermal energy in the United States - Wikipedia, the free encyclopedia - 0 views

  •  
    "eothermal energy in the United States continues to be an area of considerable activity. In 2012, the United States led the world in geothermal electricity production with 3,386 megawatts (MW) of installed capacity;[1][2] the largest group of geothermal power plants in the world is located at The Geysers, a geothermal field in California.[3] The United States generates an average of 15 billion kilowatt hours of geothermal power per year, comparable to burning some 25 million barrels (4,000,000 m3) of oil or 6 million short tons of coal per year.[4] Geothermal power plants are largely concentrated in the western states. They are the fourth largest source of renewable electricity, after hydroelectricity, biomass, and wind power. A geothermal resource assessment shows that nine western states together have the potential to provide over 20 percent of national electricity needs.[4][5]"

Geothermal Technologies Office: A History of Geothermal Energy in the United States - 0 views

  • Archaeological evidence shows that the first human use of geothermal resources in North America occurred more than 10,000 years ago with the settlement of Paleo-Indians at hot springs
  •  
    "Archaeological evidence shows that the first human use of geothermal resources in North America occurred more than 10,000 years ago with the settlement of Paleo-Indians at hot springs. The springs served as a source of warmth and cleansing, their minerals as a source of healing. While people still soak in shallow pools heated by the earth, engineers are developing technologies that will allow us to probe more than 10 miles below the earth's surface in search of geothermal energy. We invite you to study the timeline of the recent history of geothermal energy in the United States."

ELI: Energy: Support Materials: Tidal Energy - 0 views

  • People have harnessed the tides and used its energy for many centuries. Tide mills—which are the precursors to today’s tidal power plants— have great similarity to water wheels. The difference is that water must first be collected from the incoming tide before it can be released to rotate the water wheel.
  • he oldest, excavated tide mill is dated to the year 619.

How long have people been using solar energy - 1 views

  • It depends what you mean by "solar energy." Humans have always used solar energy in some sense: to warm themselves, to grow food, etc. However, I'm assuming that's not really what you mean (although it is important to realize that all energy on earth, with the exception of nuclear fission and geothermal, is ultimately driven by the sun's energy -- even fossil fuels, which after all were plants that grew with sunlight millions of years ago). Solar power has been used directly in various forms for over 100 years.

The Most Frequently Asked Questions about Wind Energy - 0 views

  • In 1997, U.S. power plants emitted 70% of the sulfur dioxide, 34% of carbon dioxide, 33% of nitrogen oxides, 28% of particulate matter and 23% of toxic heavy metals released into our nation's environment, mostly the air. These figures are currently increasing in spite of efforts to roll back air pollution through the federal Clean Air Act.
