The graph fails the plausibility check of "does using fossil fuelled car pollute about the same as EVs" and the graph trying to make out that they do. I too can ask AI questions, but I think AIs are full of shit. Here it is anyway, and the fossil fuel cars are getting a free pass for ALL the CO2 emissions during generation, which as per my other comment, are about 50 times higher assuming that oil extraction and refinery isn't actually better than natural gas:

CO2 Emissions Comparison

Assumptions

Electric Vehicle (EV):

• Average energy consumption: 20 kWh/100 km (or 0.2 kWh/km).
• Carbon intensity during overnight charging: 75 gCO2/kWh. Petrol Engine:
• Average emissions: 150 gCO2/km (this can vary based on vehicle efficiency). Diesel Engine:
• Average emissions: 120 gCO2/km (again, this can vary based on vehicle efficiency).

CO2 Emissions Calculation

Electric Vehicle (EV)
Energy consumption per mile:

• 1 km = 0.621371 miles, so 20 kWh/100 km = 20 kWh/62.1371 miles = 0.321 kWh/mile. CO2 emissions per mile:
• 0.321 kWh/mile×75 gCO2/kWh=24.1 gCO2/mile.

Petrol Engine
CO2 emissions per mile:

• 150 gCO2/km×0.621371 miles/km=93.2 gCO2/mile.

Diesel Engine
CO2 emissions per mile:

• 120 gCO2/km×0.621371 miles/km=74.6 gCO2/mile.

Summary of CO2 Emissions per Mile Vehicle Type CO2 Emissions (gCO2/mile) Electric Vehicle (EV) 24.1 Petrol Engine 93.2 Diesel Engine 74.6

Conclusion Charging an electric vehicle overnight on a greener grid results in approximately 24.1 gCO2 per mile, which is significantly lower than the emissions from petrol engines at 93.2 gCO2 per mile and diesel engines at 74.6 gCO2 per mile. This comparison highlights the environmental advantages of EVs, especially when charged during times of high renewable energy availability.
