It can't be said often enough, so I'll say it again:

Solar and batteries can power the world! It's cheaper than gas (esp. at today's prices) and a lot more reliable.

By 2030, solar and batteries could supply 90% of electricity to 80% of the world's population for < €80/MWh (including backup).

@chrisnelder personal experience with PV, thermal & battery back up have produced the following in 19 years
PV: 120MWh
Thermal: 90MWh
Still very efficient, at 92%
Battery was a late addition in 2019, but has saved average 31% of total production (14MWh so far) ensure we can go overnite w/out grid top up
10kw pv & battery system
5 kw thermal PV system

@Sine_Nomine That's awesome, esp. in England! Sounds like a pretty ideal array orientation. Have you run the numbers on the economics of your investment at all? I'm sure Farage, Badenoch & co. would be very interested in hearing them. 😉

@chrisnelder as early adopter's we paid over the odds, but did so as a long term fin & eco investment, tot cost was 19k (5k thermal, 9k PV, 5k battery)
we earn back:
FIT payment: £900 / yr : £17,000 approx
PV export: 51% ave @ 15p/KW = £9,000 to date
Paid for itself in 11.5 yrs
Co2 saved 22,912 metric ton
House runs on electric, bills are minimal
We like to think we're doing our part, environmentally speaking.
In short the numbers add up, pls tell farage & badenock 🫡
