Charging devices

We are all year round caravanners, and do not use much electric where possible, we turn everything off we can when going out and set timers for heating and hot water when required. 

Having now watched a few YouTube videos some people seem to be on a one night stay at sites to power all there power banks etc then leaving, plus people saying they leave heating on all day so as to return to a warm van.

Is this having an effect on supply demand so pushing towards metering on site 🤔 

Just a thought, or is it just us being naive. 

PS We do understand that everything is increasing 🙄
