That doesn't consider different energy use cases, existing infrastructure, and increasing global energy demands, which could require more than simply replacing the 'useful' energy currently obtained from fossil fuels.
Electricity generation (coal) ... 33-40% efficiency
Electricity generation (nat. gas) ... 50-60%
Heating (nat. gas.) ... upto 97%
Transportation ... 20-30%
Industrial ... cement for example at about 50%
What am I missing? Got any links or references for "we only need to replace the third"?
- ZeroGravitas 3y agoThis works through examples with numbers: https://ourworldindata.org/energy-substitution-method https://ourworldindata.org/energy-substitution-method Also note that heat pump based heating can be 5x as efficient as nat gas heating. Which means using gas to generate electricity to run heat pumps is an improvement. edit to add: also note that the oldest, dirtiest and least efficient plants will get shut first, having an outsized impact.
