Corporations to clean it all?

In Short

Should new regulations force corporations to purge the economic system from fossil fuels?

A Few Details

Such regulations should mandate corporations to comply in two ways:
-limit their energy usage during their production cycle;
-produce energy-efficient output that consumers could buy for cheap to replace their existing inefficient car, dirty electricity, etc.

Is it just a question of political will? Are some right to believe that the greedy oil corporations are blocking it all with lobbyists funding the election of representatives favorable to corporate profits? Or are there justifications for the political authorities to rein in a green conversion imposed on corporations?
