Today's IQ Test: Which Is Cheaper To Produce Electricity, Wind/Solar Or Fossil Fuels?
/I have been writing here for about a decade that wind and solar would inevitably prove to be far more expensive for producing useful electricity than other methods like fossil fuels, nuclear, or hydro.
The reasons are not difficult to understand. Wind and solar, due to intermittency, are not capable of powering a full-time electrical grid on their own. To make the grid capable of fulfilling customer demand 24/7/365, wind and solar require large amounts of additional capital infrastructure — dispatchable back-up generation, energy storage, additional transmission capacity, and more. If wind and solar prove insufficient to eliminate dispatchable back-up generation, then you find yourself running (and paying for) two duplicative systems, when you could have had only one. Energy storage as a potential solution to intermittency turns out to be impossibly expensive. If the only back-up generation you can find that works is powered by fossil fuels, then you haven’t even succeeded in achieving zero carbon emissions in the electricity sector.
And yet we have been, and continue to be, subjected to a constant drumbeat of advocacy claiming that wind and solar are now the cheapest ways to produce electricity. I’ll give you a few examples of that in a moment.
So who is right?
