Saving energy in general is a positive step. For example, we've just bought a new freezer and dishwasher with better energy ratings and these will save money over their lifetimes. However, when is the best time to run a wash to save the most CO2e?

Unless you are on an Economy 7 style tariff or have solar panels then when you use power has no effect on how much it costs you. If you are, then at night or in the middle of the day is better, respectively. Dynamic demand to grid signals isn't ready for consumer adoption yet but you can look at the information manually if you want to use power at less demanding times.

The grid frequency is a reasonable indicator but is pretty technical. There are other, easier to understand, data sources available:

By avoiding peak time you may not save money but you can save carbon.

I must admit, I never made the connection between time to run an appliance and the CO2 emission it will help releasing, but it's all very obvious now. Thanks js!  I know that at night when demand is low, less fossil fuel energy is thrown into the grid, and other more CO2 neutral energy sources take over. So it all makes sense. Love the links as well. Thanks again.
