I was reading an article the other day about how Trump's recent actions have led to a worldwide surge in demand for renewable energy solutions, especially for solar panels, and car dealers can't keep up with demand for electric cars.
We have solar panels plus a storage battery; no, they're not very productive from November through to Jan/Feb, but this is more than made up for by what they produce in the other months; according to our app, over the course of the year they provide 80% of our electricity - and in fact this month, which hasn't been particularly sunny, we've been 83% self-sufficient. We also have a gizmo attached to our water tank, so that once the battery is full then excess energy is diverted to the immersion heater: this supplies all of our hot water through the summer months, & in fact over the past couple of weeks (now that the sun is higher in the sky - the sun still gets through the clouds) we've only needed the boiler to heat our water for half the usual times.
