A few quote from article:
Building a new wind or solar generating plant does not result in the retirement or replacement of other generating plants in the electrical grid. The rest of the grid still has to be present to provide electricity when wind and solar are not generating. Even the massive and diverse Texas wind energy complex frequently experiences spells of very low output of less than 5% of capacity.
A kilowatt hour of wind or solar costs seven cents to generate, but its economic value is two cents for the fuel saved in the backup plants. So five cents per kilowatt hour is the subsidy that society pays for generating electricity in this fashion.
Since it costs far more to reduce the fuel consumed than it is worth, wind and solar make absolutely no sense. Neither is a cost-effective method of reducing CO2 emissions. If you justify the subsidy as an expense to reduce emissions, you find that it costs more than $100 per metric ton of CO2 emissions avoided.
