Same. I filled up my car with petrol 2 weeks ago and have driven about 6 miles since, so that's likely to last me about 3 months rather than 3 weeks. No temptation to 'pop to the shop', our weekly shop is all we are getting. No coffees at work etc, no days out, non-essential Amazon items all have about a month lead time so there is no urge to buy anything random.
there was an interesting challenge at a workplace where workers are asked to work from home. A question came in as to whether the employee would be reimbursed for the additional electricity used up working from home. It was pointed out (and I assume a quick calculation was done) that the savings from the average distance travelled to the workplace no longer being a factor would more than offset the 1 to 3 kWh (it’s about 25-30p kWh) additional electricity. (assumed fuel per mile is 7p). A round trip to work and back of anything around 12 miles would be the break even point.
