Hydroelectricity Renewable Energy Presentation Jacob Mendiola and John Treat

21% PERCENT OF WORLD’S ENERGY PRODUCED BY HYDROPOWER

9.25% PERCENT OF U.S. ENERGY SUPPLIED BY HYDROPOWER

40% HYDROPOWER IS 40% THE COST OF FOSSIL FUEL

Scientist ➔ The source of this energy is flowing water that is captured and turned into electricity ➔ The most common way of harnessing and transferring energy is putting the water flow into spinning turbines that then act as generators to produce electricity ➔ Hydroelectric power is environmentally friendly. It generates power without creating any air pollution or other toxins ➔ The company Lucid Energy has announced that it will be installing a LucidPipe, a hydroelectric turbine, into a San Antonio water main

Environmentalist ➔ There are no harmful wastes produced by hydroelectric power—it is a 100% clean energy source (“Hydropower—Energy from Moving Water”) ➔ Natural habitats are affected by hydroelectric plants in ways that may adversely affect the inhabitants, but engineers and environmentalists work closely together before construction begins in order to ensure the survival and proliferation of native species ➔ There are no concerns to public health and safety—the plants are located in the water and do not pollute it ➔ Using hydroelectricity does not contribute to global warming, as it does not produce any pollutants (“Hydropower Statistics”)

Economist ➔ It is not that simple to generalize the cost of building hydroelectric systems because of many different factors, such as the change in water levels between intake and discharge, the maximum flow rate, how the maximum power output is affected, and the type of turbine utilized ➔ Hydroelectric power plants currently employ up to 300,000 people. A new study by Navigant Consulting has found that 1.4 million jobs could be created by 2025

Historian/Sociologist ➔ Hydropower has been in use since the civilizations of Mesopotamia and ancient Egypt, “where irrigation has been used since the 4th millennium BC” (“Hydropower Statistics”) ➔ “Over one­-half of the total U.S. hydroelectric capacity for electricity generation is concentrated in three states (Washington, California, and Oregon)” (“Hydropower—Energy from Moving Water”) ➔ Our community already uses this energy source prolifically ➔ 21% of the world’s electricity is produced by hydropower; approximately 4,250 TWh is produced by the world’s hydropower plants (“Hydropower”) ➔ Hydropower affects people in that it is almost ubiquitous—it powers an increasingly larger number of services and industries the world over
