Photovoltaic and wind farms for electricity production has indeed become cheaper over the years.
Nevertheless, they are still limited for they are intermittent: the Photovoltaic panels only capture the sun’s light during day time and the wind doesn’t blow 24/7/365 at a constant rate.
We are yet to overcome this challenge in a satisfactory and sustainable manner as far as I can understand. But overcome this challenge we must if we want to base our energy on solar and wind. Batteries are improving but they are not there quite yet.
I have been against nuclear since ever. Probably a result of the Chernobyl accident. But recently I have been finding myself looking at nuclear more open minded.
I am under the impression coal is still necessary. Unfortunately, the intermittent character of both wind and solar together with the current inability to store energy sustainably makes for the need of power plants capable of producing energy when needed: coal, gas and nuclear. We all want cheap energy bills. We all want it to be sustainable. We all want it to be clean. Unfortunately, as far as I can understand it, we can’t have it all yet.
I hope battery technology, or other, develops so we can ditch coal and natural gas for good. I don’t know how long it will take. But we are not there yet.
