A fair number of solar PV installations are micro inverters and are connected to 240V AC at the panel. That is how they are in my system - three strings, of no more than 12 panels each. Each string uses a 40A (I think) 240V breaker.
The most expensive way to generate power is nuclear - this is why almost none are being built. Land based wind is the cheapest. Sea based wind is more than land, but now with the 12MW turbines, the cost of sea based systems has come down quite a bit.
Decommissioning the Pilgrim nuclear power plant in Plymouth MA will cost <b>$1,000,000,000 - $One Billion</b> and take (at least) about a decade. They said they will store the waste in New Mexico. But I think it will be staying on site in dry casks - that last only about 100 years. Who will pay in the long run?
