Hm. Not so simple. In my province (BC), over 90% of our electricity is generated by dams on rivers.[1]
I agree with you that some dams are mostly negative. And all dams have some negatives. Witness our Site C dam project currently under construction.[2] It has been a political, environmental, legal, First Nations, and agricultural shitshow. I just think it's worth knowing that river dams still produce the vast majority of electricity for a lot of people on this part of the planet. I vote for change. Fingers crossed.
