Electricity generated from the flow of running water can be the cheapest power around, being even less expensive than power from nuclear facilities. However, large scale hydro has unique issues and detractors that tarnish the image of this clean energy source which otherwise generates virtually zero greenhouse gas emissions. The allure of government-backed big hydropower projects in the developing world is proving too strong for some companies, as they seek to locate new manufacturing facilities alongside rivers where both power and water are abundant to use in industrial processes. And in this age of globalization, the merry-go-round search for low-cost venues has some companies relocating to the exact same places from which other companies have recently vacated.
