- Power outages
- More expensive nuclear electricity
- More carbon emitting gas-fired electricity
- Expensive and polluting storage
- The energy trilemma writ large - unaffordable, unsustainable, unreliable electricity
Hi , I'm Tom Langdon-Davies from a farm near Exeter in sunny Devon, South West England. I have worked all over the world for energy companies, renewable and conventional. Now it's time for me to see what I can do to raise awareness of the easy things we can do to make our energy more sustainable. Thanks for reading. Please help me by commenting!
After a brief spell seismic surveying around Europe and Africa, I ran the Natural Energy Centre in London - that was back in 1977, and we...

Is Solar in UK Like Solar in California?
On 3rd May, California had a capacity crisis. Their hydro power reserve had run out of water because of the drought, there was little wind, and the peak demand even in air-conditioned California was after dark. Demand side response came to the rescue thanks largely to Enernoc, and 800 MW was lopped off the 34 GW or so of peak demand, preventing large-scale outages. (The green net demand curve is net of solar PV and of DSR)
But look at how much of the near-peak demand is met by solar.
In UK , in winter, this would not happen. Our peak demand occurs several hours after the watery winter sun has already set.
All the more reason, then, to be concerned about getting as much time-shifting as possible out of the winter peak. The alternatives to this are:
So - be an early adopter, get ahead of the game, and prepare for next winter by planning to shift all water heating appliances out of the 3-8pm peak! Hundreds of thousands already time-shift, do you?
