Another source of resistance of the hydropower developmen comes from population displacement. In the past, half of hydropower development costs were incurred due to the displacement of residents, and many displaced migrants return after development begins. Construction costs for a hydropower plant is 40 percent higher than a fossil fuel power plant, resulting the concerns on the worth of hydropower. The most remarkable exmaple is Three Gorges hydro project too.
But for Chinese local governments, hydroelectric development is a way to displace impoverished populations and reduce a county's financial burden.
