Should more be done to introduce renewable energy as the main source?

It is no myth that coal reserves are running out and also that fossil fuels are causing pollution. London has already broken its quota for the amount of pollution in a year early this year, in only a few months. The effects of that were actually felt by many people suffering asthma, heart or lung disease - they literally could not go outside and hospital admissions for people with breathing problems went up. Perhaps it's simply time for the earth to die, or for humans to die out, but personally I would prefer a painless death, not a slow suffocation. So an uptick in "clean", renewable energy sources would be excellent. Electric cars are on the rise and London buses are being switched over into partly using electricity too - electricity which can be generated renewably. Governments should stick to the environmental targets they are set and individuals should be more mindful of the resources they use, too.
