TED-Ed・3 minutes read
Gasoline has drawbacks including environmental damage and greenhouse gas emissions, while electric cars offer a cleaner alternative and the potential to avoid emissions entirely if powered by clean electricity. Other liquid fuels, including carbon-neutral options, face challenges like cost and sustainable production methods to be viable replacements for gasoline.
Insights
- Gasoline, extracted from crude oil, has high energy content but leads to environmental harm, air pollution, and greenhouse gas emissions, impacting climate change and extreme weather.
- Electric vehicles, reliant on electricity and batteries, provide a cleaner substitute to gasoline cars, capable of eliminating greenhouse gas emissions if powered by clean energy sources.
