subject: Well Known Sources Of Alternative Energy [print this page] In history, we have seen the change in the types of energy used. Since 1200, the community shares the wood for charcoal that deforestation has occurred locally. 300 years later, when the oil companies depended later depleting the supply of whale oil used as fuel for lamps. In early 1900, ethanol from corn oil provided the energy needs.
When the world ran on the wheel and navigates the sky and the sea, there is a need for more fuel, and finally drying up local wells. Accordingly, the U.S. turned to import oil to maintain the transportation, industrial and domestic needs, moving finally to depend as much on foreign oil, 58% of its supply is now imported.
Both the depletion of our natural energy resources in the world, people are also feeling the impact of rising electricity prices and the rising cost of living expenses. At home, this is a dilemma that family needs are a priority, and absolute power be considered a leader needs.
The transition to alternative energy sources will have time to put the Act across the country, but the energy landscape changes, more houses and alternative energy industry. This will be good for the economy depends on imports of expensive oil, as the United States.
If you are indoors, solar energy is a renewable energy alternative popular choice of using photovoltaic technology to convert sunlight into electricity. Solar panels only hot water and steam. Together, these technologies of energy supply for optimal power homes. Solar energy has very low emissions of carbon dioxide emissions compared with gasoline from the same chemical element that is partly responsible for climate change.
For geothermal energy, the earth's heat is tapped to supply energy needs. To trap this energy, holes are drilled deep to the level where a possible geothermal heat spot is present. The escaping steam is directed into a turbine linked to a running generator, which converts steam to electricity. This is the preferred format for big industry and utility companies.
The head of household, therefore, should not dig so far to enjoy the benefits of geothermal energy. Geothermal heat pump uses the ground temperature safely hundreds of feet underground to provide heat and air conditioning. It can also provide hot water.
Wind energy converted into electricity using wind turbines. Wind power produces 1.5 percent of the minimum power in the world. Today, this is a popular alternative source of energy in Denmark, Germany, Spain and Portugal.
