if you look around you at everything you have that has plastic in it, mobile phone charger, pc, pc cable, bin bags, food wrapping, pens, shampoo bottles etc. Your life would be much less advanced and more miserable without fossil fuels before even talking about air travel, public and private land transport.
I agree it would be good to reduce fossil fuel consumption but unfortunately everything can't be made from plants like fast growing bamboo yet. I don't think blocking planning permission for petrol to run cars or gas to heat people's home is practical to do yet. even if we had 100% of energy from wind enough for electricity and heating and 100% electric cars, you can't harness wind every day. Solar - are you having a laugh mate. hydro - destroys the environment. Look at what Brazil is doing to the amazon.
