Unless you show us data on how much %age of total energy usage is electricity, there is no relation between the two!
According to some sources, electricity accounts for about 20% of total energy usage. So with your numbers, we would need extra 6.75% of total energy used. 6.75% of 20% is an extra 33.5% of electricity.
- onlyrealcuzzo 3y agoIt's literally right here: https://www.eia.gov/energyexplained/us-energy-facts/ https://www.eia.gov/energyexplained/us-energy-facts/ 100.4q BTU total US energy usage. 37.8q BTU electricity (~37% or ~18% depending on how you count loss). 27.5q BTU transportation (~27% OR ~36% depending on how you count loss). You're assuming that ~60% of NEW electric generation will come from fossil fuels. We won't have a ~60% loss in electric generation from solar & wind - which is currently ~90% of NEW generation. In 5 years, coal & natural gas will likely drop to ~0% of NEW generation.
- gruez 3y agoSo you admit your original conclusion of "we only need 25% * 27% = 7% more electricity." is wrong? If you take energy use used for transport (27.47), multiply it by 25% (because it's more efficient), you get 6.87. That's 18% of how much we generate in electricity today (37.75), not 7%.
- zapdrive 3y agoOk, 25% of 27.5q BTU = ~ 7q BTU So we need extra 7q BTU of electricity, right? Which is about 18% of 37.8! So, not 7, not 9, we would need at least 18% extra electricity. TLDR: Your math was wrong!
