Green power vs. “conventional”

This article talking about how cleaner/renewable power has finally reached a price parity with conventional generating methods is timely. I just got my power bill and my local Portland General Electric has a couple options for buying greener power at roughly the same price per kWh as their standard mix. They even differentiate hydro and “low impact hydro” (presumable something other than a massive dam across a major river damaging sediments, water temperatures, fish migrations, &tc.?).
I also got my gas bill. Ooof. Bad news. I’m glad I finally have window coverings on the upstairs windows at least. Went to Home Depot and bought some insulation for the outbound hot water heater pipe. Also turned the central heat down a notch.
I bought my blinds online and am happy them, and while they were easier to put up than I expected, they were not shipped in a sturdy enough box and the quality of their simple white wood blinds is not that high (IMHO subpar paint coverage and cheap plastic pulls). They’ve got a helpful website though and are quick.
