This page is an attempt to estimate how much energy it takes to sustain a reasonable quality of life in a developed country.
Tables
Energy units: W (watts per capita, averaged over time. This is not the same as peak watts). (example)Suppose an electric car charger operates at 4800 watts, but the car is only charging for 2 hours per day on average. So the wattage averaged over time is 400 watts. Also note: If a family of 2 people owns 1 of these cars, then that's 200 watts per capita.
- Non-electric energy usage (fuel) is still measured in watts, this same way, for the sake of comparison.
oecd.energy.tfc

OECD countries - energy usage - total final consumption

Population, total - World Bank Data

OECD countries are: Austria, Australia, Belgium, Canada, Chile, Colombia, Costa Rica, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Israel, Italy, Japan, Korea, Latvia, Lithuania, Luxembourg, Mexico, the Netherlands, New Zealand, Norway, Poland, Portugal, Slovak Republic, Slovenia, Spain, Sweden, Switzerland, Turkey, the United Kingdom and the United States.

Status quobased on OECD countries, most of which are developed | Status quo, electrifiedall vehicles electric instead of fossil fuels ~ Estimated based on the energy footprint of lithium-ion batteries. |
Minimal consumptionInvolves major personal & social changes: ~ Public transit and walkability ~ Frugalism ~ Abolishing planned obsolescence and code bloat | |

Residential - other Entirely electricity - anything that isn't used for heating/cooling. A lot of websites that teach you how to "save energy" are centered on this. But as you can see, it's actually quite a small part of energy demand! | |||
Commercial This is not split into heating/cooling/misc (unlike for residential) due to lack of more detailed data. | 512 W

Industrial Almost all of this is manufacturing. Other industrial processes include agriculture & mining (surprisingly minor in terms of energy use). | |||
Transport Includes passenger vehicles, freight trucks, and to a lesser extent: trains, planes and ships | 1317 W

Note on reducing environmental impacts
- When it comes to climate change: Energy usage is the main culprit.
- Home electricity is just a small part of this. The best thing people can do is drive less and buy less.
- Note: This is targeted at the average person who lives in a developed country. If you are poor, you probably don't need to consume less.
- Home electricity is just a small part of this. The best thing people can do is drive less and buy less.
- When it comes to habitat loss: Land usage is the main culprit.
- The best thing people can do is eat more plant-based and waste less food.
