Nuclear power aside there are a few examples of micro generation about – smaller generators closer to communities so you benefit from less get loss in transmission and benefit from the heat that would otherwise be lost.
One classic example is the old BBC Studios – they had their own power plant for the studio lights and piped the excess heat out to neighbouring homes.
I live close to an old mill town and the trust that adopted the land the mill used to stand on have. Every trace above ground of the mill has gone but the they found that the underground lades and the old 1950s water turbines that powered the mill are still present and intact – they’re getting ready to re-commision them and they’re expected to generate £100k a year in feed in tarrif that will fund community projects.
My house and my neighbours are all on a district heating system powered by a big wood burning boiler out the back. Reading this makes me wonder if you could use the heat to generate a bit of electric as well. There is a weir and old turbine house out the front – the ‘big house’ was an early adopter of this elektrickery back in the day but the actual turbine is gone. The turbine is only the icing on the cake though as theres 20 miles of flow management running upstream of that weir thats still in place.
