Energy from Water  By Patti Hutchison   1     Do you know that over 150,000 gallons of water flow over Niagara Falls every second? This movement releases a great amount of energy. It is used to produce electricity. How does this work? 2     At night, half the water flowing toward the brink of the falls is detoured into a tunnel system. The water flows over huge turbines. The motion of the water turns the turbines. This converts the kinetic energy of moving water to mechanical energy. It drives a generator that produces electricity. There is enough electricity made to power western New York and parts of Canada.3     Electricity that is generated from flowing water is called hydroelectric power. The Niagara is not the only river that produces this kind of power. Dams are built across rivers. Behind the dam is a reservoir. The water flows through large pipes. It turns the turbines that produce electricity. About ten percent of the electricity used in the U.S. is hydroelectric power. 4     Power from water sources has many advantages. First, it does not pollute the environment. Dams provide drinking water to surrounding areas. They control flooding. They are places for swimming, boating, and fishing. Water power is inexpensive to produce and is a renewable source of energy. 5     There are also some disadvantages of hydroelectric power plants. Building dams disrupts the habitats of both animals and people. The natural pattern of water flow is changed. The reservoir behind the dam floods the land permanently. 6     Rivers are not the only source of energy from water. The movement of the ocean waves can also be harnessed to produce electricity. Barriers have been built over ocean inlets. As the tide ebbs and flows, the energy is captured in tidal power plants. This energy is also non-polluting. However, the barriers can disrupt the marine life in these areas. 7     The cool water that flows in rivers and oceans is not the only source of energy from water. Hot water can also produce heat energy and electricity. Geothermal energy comes from Earth's internal heat. 8     As you go deeper below the surface, the temperature increases. In some places, this heat collects in large pools of steam or hot water. Wells can be drilled deep into the earth to release this energy. It can be piped to power plants and made into electricity. It can also be used as heat energy to warm homes and other buildings. Geothermal energy from water is called hydrothermal energy. 9     Hydrothermal energy is very efficient. Experts estimate that if all the geothermal reservoirs in the U.S. were tapped, they could provide more energy than the country currently uses. However, this source is hardly used today. 10     There are some good reasons for this. Hydrothermal energy is only found at certain sites. It is most efficient closest to the area where it is found. As hot water is piped away from the source, it cools, losing its ability to heat. Also, it is not a completely renewable energy source. As steam and hot water are pumped from the reservoir, cooler water takes its place. Eventually the source will run out of hot water. 11     There are many ways to produce heat and electricity from water. These are natural sources of energy. They can be harnessed to help meet our demand for power, while producing very little pollution.

Energía del agua

La electricidad que se genera a partir de agua que fluye se llama energía hidroeléctrica. El Niagara no es el único río que produce este tipo de poder. Las represas se construyen a través de los ríos. Detrás de la presa es un embalse. El agua fluye a través de grandes tuberías. Resulta que las turbinas que producen electricidad. Alrededor de un diez por ciento de la electricidad utilizada en los EE.UU. es la energía hidroeléctrica.

Poder de las fuentes de agua tiene muchas ventajas. En primer lugar, no contamina el medio ambiente. Las presas proporcionan agua potable a las zonas circundantes. Controlan las inundaciones. Son lugares para la natación, el canotaje y la pesca. La energía del agua es barato de producir y es una fuente de energía renovable.

También hay algunas desventajas de las plantas hidroeléctricas. La construcción de represas altera el hábitat de los animales y la gente. Se cambia el patrón natural de flujo de agua. El embalse detrás de la represa inunda la tierra de forma permanente.

Ríos no son la única fuente de energía del agua. El movimiento de las olas del mar también puede ser aprovechada para producir electricidad. Las barreras se han construido más de entradas de mar. A medida que los flujos y reflujos de la marea, la energía es capturada en las plantas de energía de las mareas. Esta energía es también no contaminante. Sin embargo, las barreras pueden perturbar la vida marina en estas áreas.

El agua fresca que fluye en los ríos y los océanos no es la única fuente de energía del agua. El agua caliente también puede producir energía térmica y electricidad. La energía geotérmica proviene del calor interno de la Tierra.

Energía hidrotermal es muy eficiente. Los expertos estiman que si estaban intervenidos todos los reservorios geotérmicos en los EE.UU., que podrían proporcionar más energía que el país utiliza actualmente. Sin embargo, esta fuente prácticamente no se utiliza hoy en día. Hay muchas maneras de producir calor y electricidad a partir del agua. Estos son fuentes naturales de energía. Ellos pueden aprovecharse para ayudar a satisfacer nuestra demanda de energía, mientras que la producción de muy poca contaminación.

Instrucciones: Después de una lectura atenta del texto informativo, utilizan evidencia textual en respuesta a la siguiente pregunta: Discuta la hidroelectricidad - donde esta fuente de energía proviene y por qué se considera un recurso renovable

Banco de palabras ciclo de granizo energía renovable

Energia da acquaEnergia elettrica generata da acqua che scorre si chiama energia idroelettrica. Il Niagara non è l'unico fiume che produce questo tipo di potere. Le dighe sono costruite attraverso i fiumi. Dietro la diga è un serbatoio. L'acqua scorre attraverso tubi di grandi dimensioni. Si scopre le turbine che producono elettricità. Circa il dieci per cento dell'energia elettrica utilizzata negli Stati Uniti è energia idroelettrica. Potenza da fonti d'acqua ha molti vantaggi. In primo luogo, non inquina l'ambiente. Dighe fornire acqua potabile alle aree circostanti. Controllano inondazioni. Sono luoghi per nuotare, andare in barca, e la pesca. Alimentazione acqua è economico da produrre ed è una fonte di energia rinnovabile.

Ci sono anche alcuni svantaggi di centrali idroelettriche. Costruire dighe distrugge gli habitat di animali e persone. Il modello naturale di flusso d'acqua viene cambiata. Il serbatoio dietro la diga inonda la terra in modo permanente.

I fiumi non sono l'unica fonte di energia da acqua. Il movimento delle onde dell'oceano può anche essere sfruttato per produrre elettricità. Le barriere sono state costruite più di insenature dell'oceano. Come la marea e flussi, l'energia viene catturata nelle centrali elettriche di marea. Questa energia è anche non inquinante. Tuttavia, le barriere possono disturbare la vita marina in questi settori.

L'acqua fredda che scorre nei fiumi e oceani non è l'unica fonte di energia da acqua. L'acqua calda può anche produrre energia termica e di energia elettrica. L'energia geotermica deriva dal calore interno della Terra.

Energia idrotermica è molto efficiente. Gli esperti stimano che, se le intercettazioni tutti i serbatoi geotermici negli Stati Uniti, che potrebbero fornire più energia di quella del paese attualmente utilizzata. Tuttavia, questa fonte è poco usato oggi.

Ci sono molti modi per produrre energia termica ed elettrica da acqua. Queste sono fonti naturali di energia. Possono essere utilizzate per contribuire a soddisfare la nostra domanda di energia, mentre la produzione di molto poco inquinamento.

Indicazioni: Dopo una lettura attenta del testo informativo, utilizzano prove testuali in risposta alla seguente domanda: Discutere di energia idroelettrica - in cui questa fonte di energia viene e perché è considerato una risorsa rinnovabile
