... 5 billionths of a second and solar radiation emitted over the united states is 500 times its energy consumption. "(Bortman). There is so much untouched free energy either being solar, wind, or hydro powered that it seems stubborn to me that we aren't trying to take advantage of it now. The world seems to just be watching our natural resources get consumed at ... . What we do as time passes will decide the answers to those questions. So why even risk hurting our planet to be stubborn? It's a fact that solar, thermal, wind, and hydro powered energy does not pollute or hurt our atmosphere. ...

... economic issues related to the relocation of people, there are many other problems that are associated with hydropower. For instance, hydro-development causes environmental degradation since water and land quality are affected by the flooding, erosion, and accumulation of toxic waste from hydro development. Besides high investment costs, hydropower development also has a low return on investment because the efficiency of hydropower depends ... ...
