Not as much, yes, but it's still important. Space is quite valuable even in a normal household.

- Teeboo 10y agoSpace is only at a premium because it costs more to have more space. The real question is "how much space are you willing to sacrifice for energy self-sufficiency?" In the UK, electric bills hover around $1200 a year for electric/gas households and $2000 a year for full electric. Renewable households will have a HUGE potential market. U.K. Residential market is 26 million houses. Theoretical price point of $1500 dollars (one years energy cost) = 39 billion dollar market not including the massive combined secondary services in maintenance, installation training providers, parts, etc. USA residential would be 6 times that and the provision of renewables to corporates is almost incalculable. It's an entirely new economic ecosystem divorced from petrochemical. It a price point higher than $3000 dollars we are getting into a market cap of many trillions worldwide.
- pjc50 10y agoIF you can get a solar system and batteries for £1k, then that starts to look feasible. But that's a big if. I had a 3.8kW solar system put in for £5k last year and have yet to really run the numbers on savings; the payback period is 10 years of feed-in tariff cheques. If I went off-grid that would be reduced. I don't really see why I'd want to go off-grid for its own sake, I'd rather better explore the possibilities of net metering and sharing power with the rest of the city.
