The Answer, my friend: now is the time to lean into wind

It would appear my email of Thursday was not well received in the Clark household.

“If it wasn’t miserable enough being told that I have to spend the next month at home,” Mr Clark writes “now I have ‘Pete’ from Octopus Energy emailing me and asking if I would mind terribly turning off a few appliances between 4.30pm and 6.30pm.”

I’m delighted to learn Mr Clark is a customer of Octopus Energy – thank you. The email in question was an invitation to take part in a smart energy trial we were running.

This experiment offered everyday customers free electricity in return for halving their energy use during two specific hours.
