Well, I wouldn't say "easy". Bonneville Dam puts out about 600 MW. A modern wind turbine puts out about 600 kW, when the wind is blowing of course. So, you would need 1000 of these turbines at $1M apiece. That's $1B. Next, you have to pay up the loans still outstanding for the dam and its powerhouses. That's another $760M. Now you have to dismantle all the dams, not just Bonneville. Next, you have to mitigate the loss of a navigable river to all of the upstream communities and industries.

It's pretty complicated.
