As I have already said, I am not against using more green energy alternatives, but feel for us to be totally reliant on them is a bit unrealistic at present. Wind energy is dependent on wind and if it doesn't blow then put pressure on other ways. You say people are not saying we should stop using oil and gas, but according to Just stop oil mission statement who are in league with one of the political parties by funding them, they do want to stop production.
Just stop oil mission statement
Just Stop Oil is a British environmental activist group. Using civil resistance, direct action, vandalism and traffic obstruction, the group aims for the British government to commit to ending new fossil fuel licensing and production.
IMO it will come down to economics and votes, I can't see the Middle East countries or Russia stopping producing oil and gas, and if they are to supply China, India & Brazil for example, and oil/gas is cheaper than renewables then we are going to become uncompetitive.
I say again I am not against moving towards this, but people see it is going to affect their lives in a negative way there will be resistance.
At the end of the day, none of us know how it will play out, I just feel it would be more realistic to reduce the dependants on oil and gas rather than totally cut it out in this country when others are not.
