In not entirely unrelated news, some electricity providers in the UK have been paying you to charge your electric car[0] today. There have been other days recently where the "agile pricing" has also gone below zero, e.g. 5 April[1]. With the lockdown no-one is supposed to drive anywhere unless absolutely essential though (so e.g. the NHS doesn't have to deal with casualties from traffic accidents), and they're talking about banning cars on some roads for a period when lockdown is lifted[2] (to make it easier for people to walk or cycle).
