Reduce energy demand

We should focus on the biggest factors first. Rich and middle-class people use more energy.

Pie chart of total energy consumption (FUELS + ELECTRICITY)

Note that your lights & computers are only a tiny piece of the pie. Driving & manufacturing are far more significant.

How can the world reduce its demand for energy, in order to make it easier to phase out fossil fuels and stop climate change?

FAQ

"Should I replace my computer screen with a new 'energy-saving' one?"

No. It takes far more energy to manufacture new devices than the devices ever use.

This is true in general for electronics and appliances, but there may be some exceptions. See: To replace or not to replace.

"Is there any point in saving electricity in the winter if I have to use electric space heaters anyway?"

No. Wasted electricity is the same as electric heating.

Saving energy in the winter is all about saving energy on heating.
