It helps with keeping the electricity price down. It is a renewable, green source of energy with huge potential. Some disadvantages to wind power are the cost to place a turbine and the noise it makes. Turbines are a threat to wild life and wind is unpredictable, so it may not generate any power (Maehlum, 2013). Conowingo dam is a hydroelectric facility that provides clean energy to locals in the area. It offers a cheap source of energy to home and is constant source for energy. However hydroelectric facilities can have some disadvantages if a draught ever happens or if the company relocates. Aquatic movement is limited unless the flood gates are open. An initial construction cost to open one is high and is hard to get approved to build one because of the time it takes to pay back the loan (“Hydroelectric pros and cons,” 2008). Waste to energy facility advantages has a huge impact on communities by clearing out old landfills to use the trash as a form of energy. Since these facilities use discarded materials it is a cheap way to have another energy source. This type of source will always be reliable due to people will always have waste. As with all advantages there are disadvantages too. Some disadvantages are the facilities are expensive to construct and people are not sold on that these facilities are considered clean from emissions (“Waste to energy pros and cons,” …show more content…
Dams used to be watermills to harvest energy from. Water wheels were difficult to distribute energy for long distances (“Water power,” 1998). Wind mills we only used to grind grains in the past. In today’s era, they have been repurposed to help as an alternate source of clean energy which has now been renamed as wind turbines. Solar power is not new technology and can be dated back to the seventh century B.C. when they used magnify glasses to make fires and burn ants. In today’s time period, we use solar power for solar farm plants to help bring a cost efficient energy source to homes (“The solar history,”
