Information On The True Cost Of Electricity From Wind And Solar Is Just Not Getting Out There
/Over the period from November 2018 to March 2019, I wrote a series of posts on the subject of the true costs of trying to get electricity from intermittent wind and solar sources.
The gist of all this was that you can’t realistically evaluate the cost of getting electricity using the intermittent renewable sources just by looking at the cost of making a kilowatt-hour of electricity when the source happens to be working at its best.
Sure, a solar panel may generate some very cheap kilowatt-hours around noon on a sunny June 21. But now that you’ve invested a few billion in solar panels, what is the plan to provide the electricity people need on an overcast December 21, when the panels may work at only 3% of capacity during the day and nothing at night?
If your plan is a backup system of fossil fuel facilities, now you are paying for both the solar panels and the fossil fuel plants, so you’ve close-to-doubled the cost of electricity no matter how cheap the power from the solar panels may be on the June day; plus your fossil fuel plants will still be running most of the time, and your emissions reductions will be minimal.
If you want serious emissions reductions, you will need to push past 50% and on to 100% of your power from renewables, so you will need to phase out the fossil fuel plants. And replace them with — what?? And at what cost?
