Home Reservoirs Hydroplants Wisconsin River ... Hydropower Facts How Hydropower Works Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy. Hydroplants range in size from "micro-hydros" that power only a few homes to giant dams like Hoover Dam that provide electricity for millions of people. The photo on the right shows the Alexander Hydroelectric Plant on the Wisconsin River, a medium-sized plant that produces enough electricity to serve about 8,000 people. Parts of a Hydroelectric Plant Most conventional hydroelectric plants include four major components (see graphic below): Dam. Raises the water level of the river to create falling water. Also controls the flow of water. The reservoir that is formed is, in effect, stored energy. Turbine. The force of falling water pushing against the turbine's blades causes the turbine to spin. A water turbine is much like a windmill, except the energy is provided by falling water instead of wind. The turbine converts the kinetic energy of falling water into mechanical energy. Generator Connected to the turbine by shafts and possibly gears so when the turbine spins it causes the generator to spin also. Converts the mechanical energy from the turbine into electric energy. Generators in hydropower plants work just like the generators in other types of power plants.

HYDROPOWER Although hydropower currently provides about one fifth of the world’s electricity supply, development of the world’s remaining technical potential could, by no means, cover the growth in future demand. However, carefully planned hydropower development can, and does, make a great contribution to improving electrical system reliability and stability throughout the world. Also, future development will play an important role in the improvement of living standards in the developing world, where the greatest hydropower potential still exists. This development, together with the existing installed hydropower capacity (some 700 GW), will make a substantial contribution to the avoidance of greenhouse gas emissions and the related climate change issues. Hydroelectricity, at present the most important of the clean, economically feasible, renewable energy options, can be a major benefit of a water resources development project; however, it is seldom the only benefit. Hydropower stations integrated within multipurpose schemes generally subsidise other vital functions of a project, such as irrigation, water supply, improved navigation, flood mitigation, recreational facilities, and so on. It is clear, therefore, that hydropower has an important role to play in the future, both in terms of energy supply and water resources development. As with all options, there is a need to develop the resources according to the highest social, environmental, economic and technical standards.

HYDRO-ELECTRIC POWER Hydro-electric power plants convert the kinetic energy contained in falling water into electricity. The energy in flowing water is ultimately derived from the sun, and is therefore constantly being renewed. Energy contained in sunlight evaporates water from the oceans and deposits it on land in the form of rain. Differences in land elevation result in rainfall runoff, and allow some of the original solar energy to be captured as hydro-electric power (Figure 1). Hydro power is currently the world's largest renewable source of electricity, accounting for 6% of worldwide energy supply or about 15% of the world's electricity. In Canada, hydroelectric power is abundant and supplies 60% of our electrical needs. Traditionally thought of as a cheap and clean source of electricity, most large hydro-electric schemes being planned today are coming up against a great deal of opposition from environmental groups and native people. FIGURE 1: Simplified view of the hydrologic cycle in which water is raised by solar energy and can perform work as it falls back to sea level (177K). History of Hydro Power The first recorded use of water power was a clock, built around 250 BC. Since that time, humans have used falling water to provide power for grain and saw mills, as well as a host of other applications. The first use of moving water to produce electricity was a waterwheel on the Fox river in Wisconsin in 1882, two years after Thomas Edison unveiled the incandescent light bulb. The first of many hydro electric power plants at Niagara Falls was completed shortly thereafter. Hydro power continued to play a major role in the expansion of electrical service early in this century, both in North America and around the world. Contemporary Hydro-electric power plants generate anywhere from a few kW, enough for a single residence, to thousands of MW, power enough to supply a large city.

Contact Us T HE R OLE of H YDROPOWER D EVELOPMENT in the U.S. E NERGY E QUATION Hydropower has played an important part in the development of this Nation's electric power industry. Both small and large hydropower developments were instrumental in the early expansion of the electric power industry. Thirty to forty years ago, hydroelectric plants supplied as much as 40 percent of the electric energy produced. Although the amount of energy produced by this means has steadily increased, the amount produced by other types of powerplants has increased at a faster rate. Today, hydropower, including pumped storage, supplies over 13 percent of the electrical generating capacity of the United States. Coal-fired steam generation is the number one source of electricity in the United States. Hydroelectric pumped storage shows up as a negative factor in electricity production as more electricity is used to pump the water to the upper reservoirs than is produced when the pumped-storage units are used to generate electricity. The benefit of pumped-storage is the ability to effectively shift capacity from periods of low energy use to periods of high energy use. Hydropower is the primary contributor of renewable energy in the United States.

Hydro Potential of Texas River Systems Hydroelectric Power (Hydropower) Hydropower makes use of the kinetic energy water gains when it drops in elevation. Typically, water dammed in a lake or reservoir is released through turbines and generators to produce electricity. Hydropower has been a staple of electricity generation since the beginnings of the electric age. Historically, U.S. hydroelectric generation expanded until about 1975, but its share of the national electrical energy mix steadily declined from a peak of about 40% in the 1930's to approximately 10% today.

Clean Energy Contact Us Print Version Search: EPA Home Clean Energy Impacts CLEAN ENERGY HOME ... SITE MAP Electricity from Hydropower Hydropower is considered a renewable energy resource because it uses the Earth's water cycle to generate electricity. Water evaporates from the Earth's surface, forms clouds, precipitates back to earth, and flows toward the ocean. The movement of water as it flows downstream creates kinetic energy that can be converted into electricity. A hydroelectric power plant converts this energy into electricity by forcing water, often held at a dam, through a hydraulic turbine that is connected to a generator. The water exits the turbine and is returned to a stream or riverbed below the dam. Environmental Impacts of: Natural Gas Coal Oil Municipal Solid Waste ... Nuclear Energy Hydropower is mostly dependent upon precipitation and elevation changes; high precipitation levels and large elevation changes are necessary to generate significant quantities of electricity. Therefore, an area such as the mountainous Pacific Northwest has more productive hydropower plants than an area such as the Gulf Coast, which might have large amounts of precipitation but is comparatively flat. Environmental Impacts Although hydropower has no air quality impacts, construction and operation of hydropower dams can affect natural river systems as well as fish and wildlife populations. Assessment of the environmental impacts of a specific hydropower facility requires case-by-case review.

quick advanced Scroll down for the article Go Figure - Hydro Energy Hydro energy is electricity made using water. Sounds weird, right? Especially since it's dangerous to mix the two. The water never comes in contact with the electricity. How it works is, water flowing down a river is used to spin turbines inside a generator. Large rivers with fast flowing water work the best. Hydro Facts Canada is the largest producer of hydropower in the world. The United States is second. Hydropower is clean. It doesn't produce any greenhouse gases or other air pollution. It also doesn't generate any waste products that might need special handling or disposal. Because it's carbon-free energy, hydropower doesn't burn fossil fuels, which release the same amount of carbon dioxide as the annual exhaust of 62.2 million cars (half the cars on US roads.) With the good, comes the bad. Hydropower doesn't pollute the air but large hydroelectric generating stations can damage the environment. The natural flow of water to the sea can sometimes be changed, which harms plant and animal communities along the way. Like solar and wind energy , electricity from water is renewable. Water from rivers is a natural resource so it doesn't come with some of the problems other energy sources have, such as cost and insufficient amounts.
