Hydropower relies on the building of dams which can change the eco-system, natural flow of water and even displace wildlife and entire communities of people.
Harvesting hydropower poses a risk to fish and other aquatic life and when bioenergy comes from burning crops, harvesting the large amounts of crops needed to create fuel poses a risk to our food supply.
Types of renewable energy include hydropower, geothermal energy, wind energy, solar energy, biomass, tidal energy, and hydrogen energy.
The Energy Information Administration (EIA) states that hydropower accounts for 6 percent of all electricity production in the United States, and nearly 70 percent of electricity generation from renewable energy sources.
Already there are numerous hydropower plants in place, many with plans to expand or renovate in order to generate more energy for the region.
Hydropower: Hydropower was first used in 100 BC to turn a waterwheel that turned gears used for grinding grain into flour.
With hydropower, water is forced into a dam and then pushed through a large turbine that creates electricity.
Hydropower is achieved by harnessing the energy of water from rivers and other large water sources.
Hydropower as the method of converting a flow of water into electricity was first created in 1892.
Unfortunately, solar power is intermittent and requires supplementation by other energy sources, such as hydropower or geothermal energy.
