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 jeopardizing 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.
We can't be anti-everything - we need an energy plan that adds up. But there's a lack of numeracy in the public discussion of energy. Where people do use numbers, they select them to sound big and score points in arguments, rather than to aid thoughtful discussion.
The discussion about energy options tends to be an intensely emotional, polarized, 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.
