Ontario has for some time been tied to a large American power grid covering States just to the South.  A fault in that grid caused Ontario's largest power outage.  Ontario now has a power surplus due to conservation and sells power to the States cheaper that it costs to produce.  A study of Ontario's attempt to create green power would show you that the taxpayer has been fleeced and the plan is a failure.  So don't use Ontario as a model.
Quebec also is in the process of sending hydro power South to the States but many Americans are objecting to it.
