Last week, the total output of the power station on my roof – Semington A – reached 30 MW. This after some 7 years. Although it once took a big coal burner about 10 minutes to do this, to say this, is to miss much of the point as there was (at the end of 2017) 12.7 GW of solar capacity in the UK; much of it, like Semington A, under 4kWh.
The amount of installed wind power capacity is much higher, but (as I write this at 0920 on another sunny morning) the solar output is already 9 times the wind output which is lower even than the power coming from coal. Coal!
