This assumes that the unbelievable cost figures advanced by renewable advocates are true. But they are not. Renewables still live on diesel generators providing backup and as regulation has it, they do so for free. This situation will not be manageable forever as someone will have to foot the bill eventually and this is always going to be the taxpayer, the ratepayer or both. But those are also the voters and once they smell the rat, they will start booting those proposing such nonsense out of office. As happens in Australia right now and a number of European nations. This foolishness has a predetermined breaking point.
The transition to a 100 percent renewable U.S. power grid would need investment of up to $4.5 trillion over the next 10 to 20 years.
