Compounding Small Choices

Individual energy choices feel tiny on their own, but they compound over time and across millions of homes. One LED bulb saves little, yet the same swap across every household in a country adds up to a large, lasting cut in emissions.

The biggest savings cluster in three categories: transportation, home heating and cooling, and appliance efficiency. Some changes simply move the needle far more than others, so not all green actions are equal. Putting limited time and money into the high-impact ones turns good intentions into real reductions.
