Best Answer

no need to mine or drill for fuel, no need to clean up the exhaust emission from burning the fuel, no need to deal with the left over fuel or ash. Once the initial outlay for the dams or other facility is made it's only regular maintenance of the facility. There are some environmental issues to be dealt with, such as fish ladders, river levels, etc.
