A general consumer-level scheme to tax emissions or signficantly raise electricity prices wont happen, because people will just whine that it's regressive (because obviously electricity consumed by the poor is less damaging to the environment per unit than that consumed by the rich). It's less damaging politically to target producers and industries, rather than homes. I suppose its possible that you could combine politically related agendas and have some wealth-redistribution scheme dressed up in environmental clothes where homeowners get some basic electricity allowance for 'free' and increased charges only occur to those who use more than this (ie those who use a lot of electricty end up paying for those who dont use much), but who knows.
