Perhaps we should add a fifth element to Jérôme's Creed: smart power usage - using and/or storing sporadic power when it's available, cutting back when it's not. Maybe we can recharge our cars and delivery vans when it's sunny, windy or when the tide's running.

I suppose that's included in energy efficiency/conservation, but maybe it needs to be a separate item, to flag that idea that using the same energy for the same purpose in different circumstances can make quite a big difference.


In the long run, we're all dead. John Maynard Keynes
