Oil and Gas get massive subsidies every year, but a huge part of it are the very popular heating oil subsidies that keep people alive in the winter. Could these be reduced or replaced if instead the government gave money towards families purchasing electric heaters and spending their money on that?
Edit: USA but i assume the problem is not uniquely ours
Almost, but the temperature difference is generally much greater in winter than summer meaning there is more demand for energy in winter. Also solar (and sometimes hydro) power is less effective in winter. Both factors mean that a grid that can handle summer might not be able to handle winter heat.
Remember, the above are factors. Your local grid’s exact energy mix matters here, some will have no problems.
