A recent survey by RBC Capital Markets showed that many Americans are becoming more open to living near wind, hydro, geothermal, and even nuclear power generation facilities in response to high energy prices and environmental concerns. Only 16 percent of Americans said that they would oppose the construction of any type of energy plant or facility in their hometown, down from 23 percent in 2007.
In addition to power generation related companies (mentioned in the following video) infrastructure manufacturers such as Parker-Hannifin Corporation, Foster Wheeler, and Woodward Governor Company, are just a few of the firms which could capitalize on the possible expansion of diverse power sources.
