In conclusion
* Erect onshore wind farms everywhere
* Don't install giant solar farms that ruin Britain's countryside
* Install photovoltaic and thermal solar panels on every roof of every building
* Don't install UPS batteries in homes - expensive and also they can explode, and battery manufacturing is extremely bad for the environment
* Build lots of fast nuclear reactors for base load
Everyone having solar on their roof removes bottlenecks in the grid, so expensive re-wiring not needed.
