_List of Renewable Energy Sources-Which The first is the Best?

The whole world utilizes coal, oil and gas ever since man learned the best way to drill the ground to utilize energy from fossil fuel. The health risks derived from fossil fuel are certainly not a brand new knowledge whatsoever. We all know that carbon dioxide emission of fossil fuels is the number one contributor of greenhouse gases that traps heat in the atmosphere, thus, causing our planets atmosphere. Fossil fuels also cause air, water, and land pollution that promotes health hazards. On top of it all, standard fuels are non-renewable energy sources. This means that there will come a period when the world runs out of classic fuels to utilize. If not, it'll be too expensive to extract what is left of it.

Looming through the horizon are a set of renewable energy sources that offer clean and naturally replenished choices to fossil fuels. Energy that originates from the sun, wind, ground heat, water and biomass produce little, otherwise, no pollution whatsoever. Here are some of the alternative energy that can save us in the hazards of fossil fuel.



Solar Energy - Man has since deemed sunlight powerful. The evidence of which are the myths that people have across all cultures. Japan contains the sun god, Amaterasu, Egypt has their unique version with Ra. Inside the Bible, creation began with the phrase: “let there be light.” This only proves that the ancestors have known the sun's rays as a source of energy in its purest form yet it is only a few decades ago once the technology to harness solar energy was developed. Today solar panel systems and photovoltaic cells are being used to extract sun’s heat to power generators offering electricity to several households.



Wind Energy - Another souped up that has been used by our ancestors for years and years is wind power. Seafarers are already perusing the movements with the wind to sail their ships. Farmers grind grains and pump water through windmills. Wind mill farms are now producing usable energy for several cities in america.



Hydroelectric Power - The force developed by flowing water might just be one of the most innovative among this report on renewable energy sources. It is also easy and simple to replenish as the cycle of evaporation and precipitation goes on. Flowing water is used to power wheels that drive mechanical processes. The energy released shall be captured by turbines and generators and will then generate electricity for thousands of households. This is the exact technology behind the many dams around the world.



Biomass Energy - Biomass will be the energy derived from organic compounds which can be converted to electricity and fuel. Wood is the most common source of biomass energy. In america and Brazil, food crops are now being tapped as good reasons for biofuel. Ethanol, extracted from corn and sugarcane, is but one good example. Methane gas harvested from biodegradable solid wastes coming from landfills is being changed into both biogas power plants and biofuels. Biogas proves to be the best alternative to fossil fuel like oil and natural gas.



Also included in the list of renewable energy sources are hydrogen, geothermal energy and ocean energy. Among these three, geothermal energy is most utilized as electricity in several nations. Scientists are still doing further research to harness the power of hydrogen and ocean energy as both of them are expensive and tough to obtain.
