What are the different renewable energy sources?
Renewable energy sources are naturally complemented without human help. Since the arrival of alternative energy sources, several ways of using natural and sustainable forms of energy have been used to create usable renewable energy sources. Solar, wind, hydroelectric, geothermal and biofuels are all different types of renewable energy sources that produce pure low pollution energy. Wind energy
is one of the fastest growing types of alternative energy used today. Since the first time people took to the sea in primitive sailboats, the wind has been used for its amazing power. For centuries, windmills have been used to help grind and grinding. Today, however, people use renewable wind energy by connecting modern windmills or turbines to energy collection systems. Denmark has become a leading manufacturer and supporter of wind energy, and some statistics state that 20% of the Earth's energy comes from wind farms.
People only have to look for duringthe day to see the one of the greatest resources of renewable energy: the sun. Solar energy has grown extremely to popularity, especially in the form of solar lining. Houses and even large buildings can now drive their own activities by installing solar panels on the upper part of the structure. Solar energy has become the support of the green construction, but the technology still requires a large amount of refining. Scientists specializing in renewable energy sources are constantly conducting research into more effective methods of using solar energy, including possible space power plants.
Biofuel, such as ethanol or bionaft, is an area that is currently undergoing considerable research. When you look at the green -sweetened mass that is crowded with a courtyard pond, it's hard to imagine that it could drive a car. However, biodiesel algae becomes the center of considerable attention by one of the newer renewable energy sources. AlgaeY, easily grown and produced in lakes or laboratory environments, can be one of the answers to the exhausted reserves of fossil fuels.
Certainly one of the more explosive renewable energy sources is geothermal power. This variety of alternative energy uses the captured heat of the Earth to create a large amount of usable energy. Geothermal plants usually occur near the borders of geysers or tectonic plates, now there are dozens of countries around the world. In at least five countries, geothermal plants are responsible for more than 15% of all energy production.
Although renewable energy sources are a big step forward from fossil fuels and oil dependence, they are by no means a complete answer to the imminent energy crisis. In order to build alternative energy plants and energy transport, a significant amount of practices on pollution is still required. However, each form of sustainable energy provides a piece of puzzle that can solve the oil dependence andother exhausted sources. By relying on clean and sustainable energy sources, people can slowly move away from the destructive practices of the past and towards the green future.
