The whole world relies on coal, oil and gas ever since man learned the way to drill the ground to work with energy from fossil fuel. The health risks derived from fossil fuel are certainly not a brand new knowledge whatsoever. We all know that co2 emission of classic fuels is the number one contributor of greenhouse gases that traps heat inside the atmosphere, thus, causing climatic change. Fossil fuels also cause air, water, and land pollution that promotes health risks. On top of it all, non-renewable fuels are non-renewable energy sources. It means that there will come an occasion when the world runs out of classic fuels to utilize. If not, it'll be too expensive to extract what's left of it.

Looming in the horizon are a listing of renewable energy sources that offer neat and naturally replenished choices to fossil fuels. Energy that comes from the sun, wind, ground heat, water and biomass produce little, or else, no pollution whatsoever. Here are some of the alternative energy that can save us from the hazards of fossil fuel.
Solar Energy - Man has since deemed sunshine powerful. The evidence ones are the myths we have across all cultures. Japan has got the sun god, Amaterasu, Egypt has their own version with Ra. Within the Bible, creation began using the phrase: “let there be light.” This only proves that our ancestors have known the sun as a source of energy rolling around in its purest form nevertheless it is only a few decades ago in the event the technology to harness solar powered energy was developed. Today solar power systems and photovoltaic cells are being used to extract sun’s heat to power generators that supply electricity to several households.
Wind Energy - Another strength that has been used by our ancestors since way back when is wind power. Seafarers are already perusing the movements of the wind to sail their ships. Farmers grind grains and pump water through windmills. Wind generator farms are now generating electricity for several cities in the usa.
Hydroelectric Power - The force created by flowing water is arguably one of the most innovative among this set of renewable energy sources. It is also the easiest to replenish because cycle of evaporation and precipitation continues on. Flowing water is employed to power wheels that drive mechanical processes. The power released shall be captured by turbines and generators and can then generate electricity for thousands of households. This is the exact technology behind the countless dams around the world.
Biomass Energy - Biomass could be the energy derived from organic compounds which can be converted to electricity and fuel. Wood is easily the most common source of biomass energy. In the us and Brazil, food crops are now being tapped as good sources of biofuel. Ethanol, extracted from corn and sugarcane, is a good example. Methane gas harvested from biodegradable solid wastes received from landfills is being changed to both biogas power plants and biofuels. Biogas is the best alternative to fossil fuel like oil and gas.
Also included in the listing 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 continue to be doing further research to harness the power of hydrogen and ocean energy as are expensive and hard to obtain.
