Webmaster HYDROPOWER HYDROPOWER INTRODUCTION This site deals with hydropower and all of the ways that hydropower affects our energy consumption by giving us a cheaper alternative to conventional approaches to energy 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 ADVANTAGES 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. DISADVANTAGES Along with these advantages come many disadvantages. many of these disadvantages come from the

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."

Hydro Energy 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.

Alternative Energy Sources 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.

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: the amount of power available from the stream, and if it is sufficient to meet power requirements; legal restrictions-local, state, and federal, on the development of the hydroelectric site, and the use of the water; the availability of turbines and generators of the type or capacity required; the cost of developing the site and operating the system; and the rate a utility will pay for electricity you generate (if you connect to their system). 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.

Green Energy Renewable 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 world’s 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.

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.

United Nations Environment Programme National Committee for the Republic of Korea Home Renewable Energy BioEnergy Solor Energy ... 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) An impoundment facility, typically a large hydropower system, uses a dam to store river water in a reservoir. The water may be released either to meet changing electricity needs or to maintain a constant reservoir level. Diversion (run-of-river) A diversion, sometimes called run-of-river, facility channels a portion of a river through a canal or penstock. It uses the natural flow of the river and produce relatively little change in the stream channel and stream flow.It may not require the use of a dam.
