An interesting question and naturally a double meaning as I live in Slovakia and there has been a huge fight over Gas supplies.
So what's my answer? YOU!
Gas won't last for ever and people who think that just because they can pump fuels from the ground gives them power are very silly.
The last few days have seen political people from various countries claiming they can fix things and the fact is they could have done so had they acted years ago.
The power is in renewable energy - solar panels, wind turbines. They could easily be added to so many countries, even wet and windy GB, and they could produce huge amounts of fuel.
Both Russia and the UK produce huge amounts of gas and oil, diverting profits from those resources, which they clearly will not do, would make the earth cool down (after a while), avoid the need to build even more pipes across countries.
However, one tiny problem. If you don't hold power by supplying people with power, then you need to hold power by earning respect - not something everyone can do!
As a collective, WE HAVE THE POWER TO MAKE THE CHANGE. Use low-energy lamps! Look at investing in Solar! And as crazy as this sounds to some, if you can work from home for a day a week - DO IT! Just think how much energy would be saved if millions of people a week worked from home for one day and saved all the fuel they use travelling to work.
