This energy originated as early as 5000 B.C. People back then used windmills to grind grain in Persia and pump water from wells in China (Learning). Wind energy is harnessed today by wind turbines that rotate using the wind to move them. Three propellers spin a rotor that is connected to a main shaft which then spins a generator to create the electricity. These can mainly be found in extremely large fields throughout the mid United States where the grasslands are windy enough to generate steady amounts of power. Wind turbines can produce on average 6 million kWh in a year (Division). Wind energy is one of the safest sources of energy you can find. Turbines do not produce emissions that pollute the air or give off greenhouse gasses that attribute to global warming, whereas power plants rely on the combustion of fossil fuels to produce energy (Povey). Wind energy will also help to stop acid rain indirectly by reducing these emissions. Acid rain is exceedingly harmful to crops and livestock in affected areas. By using wind energy, some of these pollutants are reduced and hopefully will soon be eliminated. There are a few negative things about these wind turbines, but they are not too severe. Wind turbines can be a danger to skybound wildlife such as birds and bats. They have been reported to kill anywhere from 10,000 to 440,000 birds a year, but this is nothing compared to the 976 million killed just from running into buildings …show more content…
Biomass is fuel developed from organic materials and biological waste like trees, crops and forest residues. These materials are burned in industrial facilities and generally put off less hazardous emissions than the normal fossil fuels. When biomass is burned, it produces heat and steam that runs a turbine to create power (Povey). Biomass is very economically safe. It uses things that would generally be put in landfills, tossed aside, or left to rot and degrade to produce clean energy. Although it is renewable and better than fossil fuels, it is not one of the greater quality options available. When burning, it still produces emissions that can be dangerous, but it is less than when fossil fuels are burned. Biomass is also not very cost effective. It take a lot of time and effort being put into it to get the results we need. This causes the price of the energy produced to be forced to raise so that the extra work put in is accounted
