Electricity is only part of energy use and emissions production. In no way is there a simple and cheap solution, all proposals have tradeoffs and costs
Electricity can replace the need for gasoline, diesel, natural gas, fuel oil, coal etc across a wide range of applications while saving money. Thus the talk of heat pumps and EV’s in that post. Which then further reduces the need to extract, transport, and refine oil, natural gas, and coal further reducing methane from leaking pipes etc.
However, doing so requires ramping up electricity production and storage.
Replacing gasoline and diesel use in cars and trucks removes 10% directly at the tailpipe and another 3-5% indirectly. But EV’s need electricity thus clean electricity can offset more than its current 20% share. The actual calculation depends on unknown factors like how we ramp down oil production, ethanol use, and how refineries adjust to changing demands.
Add heating for buildings + hot water + industrial processes that can use electricity instead of fossil fuels alongside indirect effects like methane leaks from pipelines and drumroll.
We can get to ~50% reduction while saving money over using fossil fuels.
