Technology that works now, not 5/10/20 years from now. Cheap to build, cheap to run. Free fuel for the next several billion years. .

California, Denmark, Germany, for example, have some of the most expensive electricity in the developed world.

In nuclear powered France residential electricity costs 34 cents a kilowatt hour. The carbon intensity of that electricity is 24 gCO₂eq/kWh. ( Low carbon intensities are good. )

In wind-and-gas powered Denmark the numbers are 44 cents and 103 gCO₂eq/kWh.

Here in solar-and-gas powered California, where I live, it's 42 cents and 123 gCO₂eq/kWh.

Germany is a basket case. Their plan to quit coal and nuclear power in favor of a hybrid gas-wind-solar electric grid went horribly wrong. They pay 47 cents a kilowatt hour for electricity and their carbon intensity is 323 gCO₂eq/kWh

I think it's pretty obvious at this point (to me anyways) that "renewable" energy cannot displace fossil fuels entirely, which is something we need to do. At a certain point adding additional wind or solar to an electric grid increases the price of electricity without a proportional decrease in greenhouse gas emissions.

from utilities. They oppose roof top solar (private ownership) but are all in for utility ownership. My state allows rooftop solar, but the utilities do all they can to stymie the process. The other problem is the tariff rates are still set based on the price of methane, rather than the actual cost of solar/wind. For example, my utility charges its customers roughly 12¢ /kWh, whereas my solar array generates power for 5¢/kWh. They create a lot of barriers to rooftop solar, but that is a regulatory reform issue.

We must fight hard to permit rooftop solar, which is far cheaper than utility solar.

About a third of the homes in my neighborhood have it, the schools and hospitals have it, many of the big box stores have it, and the nearby supermarket has it shading their parking lot. ( Parking lot solar is very nice on hot sunny days. Everyone can park in the shade. )

The only problem I have with that is that it raises the overall cost of electricity for people who can't install solar because they don't own the buildings they live in. In effect residential solar becomes a regressive tax on electricity. Lower income people end up subsidizing the solar installations of affluent people who like to brag about their electric meters running backwards.

to the utility's low income program. I wish I could cut the utility out as the middleman, but I have to work through their program.
