This is the only part of your reply that seems coherent, the rest is your usual meandering ramblings.
I asked chatGPT that question because google search did a sh*t job.
What is the efficiency of charging and running an EV by comparison to an ICE car?

When comparing the efficiency of charging and running an electric vehicle (EV) to an internal combustion engine (ICE) car, several factors come into play. Here’s a breakdown of the key points:
Energy Efficiency
- EV Efficiency:
- Electric Motor Efficiency: Electric motors are highly efficient, with typical efficiencies ranging from 85% to 95%. This means that most of the electrical energy stored in the battery is converted into motion.
- Energy Use: EVs often use about 0.2 to 0.3 kWh per mile, translating to roughly 3 to 5 miles per kWh.
- ICE Car Efficiency:
- Combustion Engine Efficiency: ICE engines are less efficient, typically converting only about 20% to 30% of the energy in gasoline into useful motion. The rest is lost as heat and friction.
- Energy Use: ICE cars usually achieve about 20 to 30 miles per gallon, which is roughly equivalent to 0.033 to 0.05 gallons per mile.
- EVs:
- Power Generation: The efficiency of generating electricity varies based on the source. Coal-fired power plants are less efficient (around 30% efficiency), while natural gas plants are somewhat better (around 45% efficiency). Renewable sources like wind and solar can be nearly 100% efficient in terms of converting natural resources into electricity.
- Transmission Losses: There are losses associated with transmitting electricity from power plants to charging stations and then to the vehicle. These losses are typically around 5-10%.
- ICE Cars:
- Fuel Extraction and Refinement: The efficiency of extracting, refining, and transporting gasoline or diesel contributes to overall inefficiency. This process typically involves losses of around 10-15%.
- Overall Efficiency: Combining engine efficiency with fuel extraction, refining, and distribution, ICE vehicles often have a well-to-wheel efficiency of around 15-20%.
- EVs:
- Emissions: EVs produce no tailpipe emissions, which can significantly reduce overall emissions if charged from renewable sources.
- Maintenance: EVs generally require less maintenance because they have fewer moving parts and no need for oil changes.
- ICE Cars:
- Emissions: ICE vehicles emit CO2 and other pollutants directly from the tailpipe. Their environmental impact can be reduced with improvements in fuel efficiency and emission controls, but they still contribute to air pollution and greenhouse gas emissions.
- Maintenance: ICE vehicles typically require more frequent maintenance, including oil changes, and have a more complex mechanical system.
In summary, EVs are generally more energy-efficient than ICE vehicles. The higher efficiency of electric motors compared to combustion engines, combined with the potential for using renewable energy sources, makes EVs a more efficient choice in terms of energy consumption and environmental impact. However, the overall efficiency of EVs can be affected by the sources of electricity used for charging and the energy losses in the power generation and distribution process.
