Extractions: In fact, hydropower is the largest renewable energy source in the United States, generating about ten percent of our nation's electricity. This amounts to million barrels of oil. This shows that hydropower has made its contribution to supplying energy to our nation. There are many examples of working hydroelectric plants out there There are many advantages to this type of energy. One would be storage. This would primarily include resevoirs and lakes behind dams . Also, hydropower allows for quick availiability. Turbine-generators are not turned off, requiring only 45 seconds. Even if the generators are not on, only 90 seconds are r equired. And a major advantage comes from the fact that the fuel is free. Also, hydropower produces no air emissions at all and no liquid or solid wastes. Along with these advantages come many disadvantages. many of these disadvantages come from the
American Rivers - House Energy Bill: Hydropower Title Worse Than Last Year's

http://www.amrivers.org/pressrelease/energy031203.htm

Extractions: Liz Birnbaum, 202-347-7550 Supporting documents: As the House of Representatives moves towards a new comprehensive energy bill, American Rivers today testified before the House Energy and Air Quality Subcommittee the current draft would rollback 80 years of established environmental protections at hydropower dams in the name of regulatory "streamlining." Under the currently proposed language, more than 500 dams on 150 rivers in 38 states would sail through less-stringent licensing procedures in the coming 15 years costing the nation a once-in-a-lifetime opportunity to restore thousands of river miles. The conservation community called on Congress drop the so-called "Title III" altogether and instead allow the Federal Energy Regulatory Commission (FERC) and other federal agencies to continue their promising initiative to reform the hydropower licensing process with administrative changes. "As currently written, the bill would not 'streamline' anything. Instead it would let dam owners off the hook from their most basic environmental obligations and strangle everyone that might object in red tape," said Rob Masonis, Northwest Regional Director of American Rivers. "This language is actually worse than anything contained in either the House or Senate energy bills from last year."

Extractions: Renewable Energy Programs Hydropower the largest-used renewable resource for electricity in Iowa is an emissions-free, renewable, and reliable energy source. Hydropower in the United States avoids the burning of 121 million tons of coal, 27 million barrels of oil and 741 billion cubic feet of natural gas, combined. Hydropower also accounts for 81 percent of the nation's total renewable electricity generation, making it the nation's leading renewable energy source. Advantages of hydropower include the absence of air pollutants or waste products during operation, and low operating costs. Environmental Impact Large-scale hydropower projects can have environmental disadvantages, such as a negative impacts on aquatic life and habitat, water and land quality. The reservoirs created by hydropower projects frequently engulf large areas of forest, farmland, and wildlife habitats. These problems can be solved with proper siting, design and planning procedures. Hydropower History in Iowa In 1999, just under 1 percent of Iowa's energy consumption came from hydropower generated in Iowa.

http://www.pge.com/microsite/PGE_dgz/more/alternative.html

Extractions: Alternative energy sources are resources that are constantly replaced and are usually less polluting. They are not the result of the burning of fossil fuels or splitting of atoms. The use of renewable energy is contributing to our energy supply. Some alternative energy sources are: biomass, geothermal, hydroelectric, solar, wind power, fuel cells, ocean thermal energy conversion, tidal energy, and wave energy. Biomass is renewable energy that is produced from organic matter. Biomass fuels include wood and forest and mill residues, animal waste, grains, agricultural crops, and aquatic plants. These materials are used as fuel to heat water for steam or processed into liquids and gases, which can be burned to do the same thing. With more use of biomass at lower production costs and better technology, the United States could generate as much as four-and-a-half times more biopower by 2020. It is estimated that biomass will have the largest increase among renewable energy sources, rising by 80 percent and reaching 65.7 billion kWh in 2020. Geothermal energy Hydroelectric (hydropower) energy employs the force of falling water to drive turbine-generators to produce electricity. Hydropower produces more electricity than any other alternative energy sources. It has been estimated that hydroelectric power will decline from 389 billion kWh in the U.S. in 1999 to 298 billion kWh in 2020. This decline is expected because most of the best sites for hydropower have already been developed and because of concerns about the adverse impact that large-scale hydroelectric facilities may have on the environment.

Extractions: People with streams flowing through or near their property sometimes wonder whether they can use a hydro-electric system to power their home or sell electricity to a utility or both. Many factors determine the feasibility of such a hydroelectric systems. These include: Foundation for Water Energy Education (FWEE) The Foundation for Water and Energy Education discusses the Columbia River Basin watershed and its ecosystems at its web site. "The romantic and mythic nature of the Columbia River is something that cuts across both generations and cultures," says FWEE. Some Native Americans call it "Nch-i-wana," or the Big River. Lewis and Clark wrote about its beauty, power, and changing nature in their diaries. The site also features a primer on hydropower and excellent graphic descriptions.

http://www.climate.org/topics/green/hydro.shtml

Extractions: Green Energy Hydropower Hydropower is the only renewable resource currently used on a large scale to generate electricity. In 1998 hydropower contributed 2.7% of global primary energy and between 15-20% of the worlds electricity supply. Huge estimates of the theoretical annual potential of world hydroelectricity have been made. However, this potential is much greater than what is actually technically, economically, or environmentally feasible. Hydro dams are present in almost all regions of the globe and have played a key role in development for thousands of years. Many modern dams are multi-purpose built primarily for irrigation, water supply, flood control, electric power and improvement of navigation. They also provide recreation, such as fishing and swimming and become refuges for fish and birds. In the last two centuries they have also played a key role in producing large-scale power and electricity. Dams also slow down streams and rivers so that the water does not carry away soil, thereby preventing erosion. Hydroelectric plants can range in size from less than 100 kilowatts to several thousand megawattsp>. p>If completed, the Three Gorges Dam on the Yangtze will be the largest hydroelectric dam in the world. Its installed capacity will be about 17,680 MW expandable with additional turbines to 22,800 MW, which is nearly twice the power of the next largest hydropower plant, the Brazil-Paraguay Itaipu dam.

Extractions: 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.

Korean Introduction Hydropower Flowing water creates energy that can be captured and turned into electricity. This is called hydropower. Hydropower plants capture the kinetic energy of falling water to generate electricity. A turbine and a generator convert the energy from the water to mechanical and then electrical energy. The turbines and generators are installed either in or adjacent to dams, or use pipelines (penstocks) to carry the pressured water below the dam or diversion structure to the powerhouse. Hydropower can be categorized into three types; Impoundment (peaking)

Extractions: Hydropower is a renewable, clean source of energy, but it can change the environment when damming rivers and creating reservoirs is necessary. Hydropower plants produce almost no emissions, because they do not need to burn any fuel for the energy that they produce. They also are located at the source of their energy supply, so there is negligible emissions from transporting this energy. Alternative Energy Sources
