We are all dependent on power. Consuming, moving, entertaining, understanding, producing… all demand substantial amount of it. But, although power availability presents a excellent comfort these days, the production technologies and sources applied also present a excellent danger, to ourselves, future generations and our planet. Renewable energy sources may help to lower the risks considerably and develop a brighter tomorrow (and tomorrow at all) for the future.
Geothermal power, harnessing the heat of the earth to produce electrical energy, is recognized in most states but not Vermont, New York, Minnesota, Illinois, Indiana or Connecticut. Solar thermal electric, where solar energy is used to heat water to high temperatures then sent through turbines to make electrical energy, counts toward RPS in most states.
It is dark, incredibly loud (we had to put on earplugs), hot (particularly if you happen to be standing anywhere near the boiler, inside of which a giant fireball rages at temperatures about two,000 degrees Fahrenheit), and sooty. Walking down a stairwell, I instinctively gripped the railing and my hand came away covered in a fine layer of coal dust. There are pipes and tubes and giant boilers and huge generators and machines of all sorts functioning full blast, 24 hours a day. It is impossible to spend a day inside a coal power plant and not come away impressed by the sheer, raw energy of the point.
Wind power is 1 of the fastest power sources to bring on stream. The neighborhood of Kodiak is organizing to meet 95% of its power require from renewable sources by the year 2020 from wind. Kodiak not too long ago invested $21.five million in wind turbine that started operating in 2009. The wind power alone will save the neighborhood 800,000 gallons of petroleum-primarily based fuel annually, worth about $two million. An additional instance is on Fire Island in the Cook Inlet, south of Anchorage. A wind farm is below construction there that will make power adequate to heat and light 19,500 residences.
Sweden has a considerable share of power coming from hydro, too. It, as well as Norway, produces just about its whole renewable energy share from hydro sources. Sweden has 44.3% of its total energy consumption from hydro sources. This quantity lets Sweden be the second nation in Europe and the fifth country in the globe by hydro power production.15 Yet another country with a considerable quantity of hydro …
