Trout and salmon depend on cold water to live. ... "Hydro electricity is generated through water pressure. ... Pipes or channels are then used to direct water from the storage to the stations. Within the station, water pushes the turbine that generates electricity. ... But in return air, chemical, water, or thermal pollution would not be present" ("Wind, Water, Sun, or Coal"). ...
Solar energy systems are sustainable because they create no pollution and consume natural energy, unlike the fossil fuels used now to produce electricity and heat. ... They produce a clean, reliable energy that will greatly contribute to the reduction of using fossil fuel According to Tom Henheffer," 'fracking' is the horizontal drilling and hydraulic fracturing of shale rock in which each operation needs 11 to 26 million liters of water, which is mixed with toxic chemicals.... " Shuster uses this information to support his argument that with a constantly increasing natio...
"Wind and solar energy are reliable sources of electricity that can diversify our nation's energy portfolio" (CLE), the United States is gradually rising in the amounts of pollution and excess wastes that have been accumulated over the years. Although the preservation of energy may be costly, the increase in global pollution could eventually cost not only money but lives. ... By 200 B.C., simple windmills in China were pumping water, while vertical-axis windmills with woven reed sails were grinding grain in Persia and the Middle East" (WEF). ... "Solar water heating pa...
The use of wind power in Cuba is extensive, and there are more than 8000 windmills for mechanical water pumping currently operating along with many small wind turbines. Since the majority of Cuban windmills are used for water pumping, the Cuban wind potential has not been sufficiently studied from the perspective of electricity generation, although some wind zones have been detected that offer good possibilities. ...
However, the technology or knowledge is not yet known to be majorly efficient, so current uses that help save some money and energy are that it can "be used to charge storage batteries aboard boats, to operate lighthouses, used in remote areas for pumping water either for cattle or irrigation, and to supply power for emergency telephones on highways. "(Bortman) All of which, do not cause air pollution, appealing to the people who strongly believe in global warming. ...
