Fridges can be modified to nudge their internal thermostats up and down just a little in response to the main's frequency in such a way that, without ever jeopardising the temperature of your butter, they tend to take power at times that help the grid.

I would like to help people have honest and constructive conversations about energy. We need to understand how much energy our modern lifestyles use, decide how much energy we would like to use in the future, and choose where we will get that energy from. David J. C.

I was distressed by the poor quality of the debate surrounding energy. I was also noticing so much green wash from politicians and big business. I was tired of the debate - the extremism, the nimbyism, the hair shirt. We need a constructive conversation about energy, not a Punch and Judy show. I just wanted to try to reboot the whole debate.

The discussion about energy options tends to be an intensely emotional, polarised, mistrustful, and destructive one. Every option is strongly opposed: the public seem to be anti-wind, anti-coal, anti-waste-to-energy, anti-tidal-barrages, anti-carbon-tax, and anti-nuclear. David J. C.
