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.

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/
says that solar+battery produces higher emissions than solar+power from grid
- 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.
