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.

Status quo[''']based on OECD countries, most of which are developed Status quo, electrified[''']all vehicles electric instead of fossil fuels

~ Estimated based on the energy footprint of lithium-ion batteries.
Minimal consumption[''']Involves major personal & social changes:

~ Public transit and walkability

~ Frugalism

~ Abolishing planned obsolescence and code bloat
Residential - heating [''']~ heating indoor air (not water)

~ varies with the weather and local climate

~ energy may be fuel or electricity

Residential - other [''']Entirely electricity - anything used in the home (except for heating/cooling; also does not include charging electric vehicles, as that goes in "transport").

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!

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. 
  • When it comes to habitat loss: Land usage is the main culprit.
