Australia, specifically South Australia is leading the species on the implementation of PV and batteries. So they are a world leader. The UK does wind power at sea, again as a world leader. We'll see if this catches on? For MSR or any other reactor type, its gotta be safe enough. Not safe enough, just build these smaller? Naw! I am not anti-nuclear, just need to know what makes them safer now, the engineering, chemistry, physics. What's the McGuffin that makes it work better now?

These figures seem a little dodgy. We have solar panels on half our roof (the difficult half, because of aesthetics, we didn't want to cover the western half that faces the street). So about 16kW of installed capacity. Average production year round is about 1kW. Our usage is about half that, so we end up selling quite a bit of electricity to the grid (at about a third of the cost to buy it). Its a 4 bedroom house, but just the two of us live here now. We do the best to arrange for heavy electricity usage to occur when the sun is shining. During the summer quarter, our electricity bills are actually negative. So of your figures above - 10kW continuous consumption seems like an awful lot. Maybe you could do it if you ran air conditioning 24x7, but it'd have to be a big A/C system. Quoting https://energyusecalculator.com/electricity_centralac.htm A central air conditioner will run 3 to 7 months of the year depending on the outside temperature. An average central ac will use 3000 to 5000 watts of power for around 9 hours a day during the hotter months. Still well under 10kW average consumption. We're lucky, we don't need air conditioning, and rarely even use a heater. > And of course the energy needed to run a house is only a > small part of the total energy budget human civilization needs, it doesn't > include the energy needed to run cars and planes and ships, and neither does > it > include the energy needed to run industry.
