I read recently that Governor Inslee was going to try to shut down some of Washington State’s hydro power dams. Washington state needs a lot MORE hydro power, not less. Hydroelectric power is probably the single cleanest source of power on the planet – oil and coal cause pollution that kills millions of people with lung cancer and other problems, solar is still pretty inefficient and requires lots of oil to produce, and people are afraid of nuclear waste (though it’s not a serious problem if you have political willpower to dispose of it properly). We should be building lots more dams, not less.
The strongest argument people have against hydro power is that it damages salmon runs. There are some great solutions for this including salmon ladders or simply just farming salmon instead.
