What do you do, when the world is at war and gas prices go through the roof ? 

I forgot to mention that that clean air means also less severe symptoms from diseases like Covid.
Note that the Russians fund their war with fossil fuel revenues mainly. So if you can't fight, stop using their gas and oil to defund the war, is the best you can do at the moment.
Make sure to get a green energy provider. If you want to get rid of bills completely invest in solar panels on your roof and a tesla battery.
Talk to you landlord about putting solar panels on your roof. Start a survey in the neighbourhood to see where else you can put panels. It can save you tons of money !
