In short, it’s not an easy task to reduce climate warming gas emission. Some solid evidence to see potentials on EV and nuclear power in the future. Hard to replace fuel in large transportation vehicles.
- 51 billion tons of greenhouse gas emission per year. Target to
zero emission
- 27% from electricity (coal 36%,Natural gas 23%,nuclear 10%,
oil 3%)
- 10% from making steel and cement, 21% from plastic
- 19% growing things （plants, animals)
- 16% getting around (plane, truck, cargo)
- 7% keep warm and cool
2. fossil fuel is ~5 trillion USD per year industry
3. COVID-19 only reduces 5% of emission by less drive
4. 1/15 CO2 emit today stay in atmosphere 10,000 years
5. In the future, there will be more storms, wildfires, higher sea
levels, less productive in animal meats. Cause 5 times more
death than COVID-19 per year
6. Fossil fuel like water, we like fish.
7. EV owners only save money only if gas cost more than ~$3
per gallon
8. Battery weigh 35x than gas to get same amount of energy.
Over bus size vehicle will be limited for battery to use. Fuel
account for 20~40% of airplane weight
