5th grade geothermal energy
… a person takes a hot bath, the heat from the water will usually warm up the entire bathroom. Geothermal reservoirs of hot water, which are found a couple of miles or more beneath the Earth’s surface, can also be used to provide heat directly. This is called the direct use of geothermal energy.
Geothermal direct use dates back thousands of years, when people began using hot springs for bathing, cooking food, and loosening feathers and skin from game. Today, hot springs are still used as spas. But there are now more sophisticated ways of using this geothermal resource.
The Benefits of Geothermal Power
Using the water at geothermal power production sites, whether in the form of steam or hot water, does not deplete the water supply from the surrounding ecosystems as long as it is pumped back into the earth’s crust. Because geothermal plants rely upon the interaction of water and molten rocks beneath the crust of the earth, they are also not dependent upon the weather or time of day to produce energy. In addition, the temperatures underground stay consistent throughout the year. For example, a wet water reservoir that has an internal temperature of nearly two thousand …
In Europe, modern renewable energy sources technologies were explored thoroughly for the first time after the oil embargo/ price crisis of 1973. Notably, market introduction of renewable energy technology started in about 1985, but the renewable energy sources industry has become vital only during the past decade. Accordingly, relevant statistical renewable energy sources data have been systematically compiled only over the past decade, although reliable and consistent statistical renewable energy sources data, collected since 1989, exist for all 15 countries of the European Union and for Western Europe (defined here as …
… Skystream 3.7 from Southwest Wind Power allows homeowners and business owners to harness wind energy and take control of their energy bills like never before.
Specifically for Grid-Connectivity - Skystream 3.7 is specifically designed for utility-connected home and business use. In certain states consumers can take advantage of “net-metering” or the sale of unused energy back to the power grid.
Low Cost - Skystream 3.7 costs approximately $12,000 to $18,000* to purchase and install, although costs vary depending on your site. Depending on the tower and installation costs, …
When it comes to considering a certain type of energy as low cost, one must analyze the costs of the energy source, its availability or scarcity, and the production costs involved in developing that type of energy. Here are a few of the most talked about energy sources – starting with coal and nuclear power energy and moving on to alternative energy sources.
Coal is …

A recently published round-up of the biggest renewable energy projects completed during the year shows that, despite the global recession, the sector remained buoyant during 2010. The list of record-breaking projects was put together by the editors of Renewable Energy World.
2010 was the year in which offshore wind came of age. The UK’s Crown Estate led the way, announcing the winners of its Round 3 tender process in January 2010, which will see an additional 32 gigawatts (GW) of clean electricity feeding into the UK grid from offshore wind farms in the North Sea, on top of the 8 GW …
