I just bought a new car and chose a hybrid with a 1.3 kWh battery in it. According to FuelEconomy.gov: - Corolla Regular LE: 316 g-CO2/mi (35 MPG) - Corolla Hybrid LE: 210 g-CO2/mi (50 MPG) - Tesla Model 3 RWD: 110 g-CO2/mi (134 MPGe w/ avg. US electrical mix) So as I see it: - First 1.3 kWh: 33% reduction - Next 58.7 kWh: 32% additional (total 65% reduction from original 316 g-CO2/mi) So why haven't we made every vehicle a hybrid first before pushing full EVs? Why aren't there incentives for regular hybrid vehicles. Seems like a terrible waste of resources when everything is so supply constrained.

Supposedly hybrids can't be as efficient overall. They're carrying around double the infrastructure. Still, hoping to get one myself before going all electric.

  I mean, yeah my comment shows that

an EV + home solar = 0g CO2. You can never do that with a hybrid. Plus that CO2 generation with an EV happens at a power plant and can be contained much easier (or sidelined when enough wind/solar replaces it). Hybrids also still emit other toxic things like NO2, and require maintenance. Finally, an EV is simply a better product than any ICE (hybrids included). They are faster, quieter, less stinky and require no trips to the gas station or mechanic. I simply can't go back.

  Solar is not 0g CO2e. https://www.sciencedirect.com/science/article/abs/pii/S0048969720370595 https://www.sciencedirect.com/science/article/abs/pii/S00489... says it's 14-73g CO2e. Home solar systems are probably less efficient so it could be even more. Do you have a battery to store the solar as well? You should account for the CO2 from its manufacture and losses from charge/discharge, too. This paper https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8654984/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8654984/ says that solar+battery produces higher emissions than solar+power from grid
