It was in the news today that another nuclear power station is planned for the south of England (Suffolk). (We had Wylfa B planned for Anglesey but that was shelved).
The construction cost for Sizewell C is said to be £20billion. That’s a nice round number that someone came up with, but we can expect it to come in over budget, and at the tax-payer’s expense (it’s going to take 10 years to complete, apparently).
The news report said that the power station will provide electricity for 6 million homes.
Now, I don’t have a fag packet to do the sums on but 20 billion divided by 6 million comes out at quite a lot per home (3.3 million by my estimate but maths isn’t my strong point), but I can see that solar panels on each of those homes would surely be more cost effective.
The news report (BBC) also said that the power station will fill the gap where solar can’t provide; i.e. at night time or during cloudy weather, so that surely answers the question of “Why?” Well, how about provide 6 million homes with on site storage for the solar-produced electricity, to tide them over during times with insufficient sun? It would still be cheaper, no?
