5. Saving Water by Using Less Electricity
Georgia consumes ~ gallons of water per kWh.
In 2015, the average annual electricity consumption for a U.S. residential utility customer was 10,800 kWh in the U.S. and 13,060 kWh in GA (~4,000 gallons).
U.S. households spend 3.5% of their disposable income on energy: their “energy burden”.
Atlanta has the fourth highest energy burden of any major city in the U.S. at 5.0%.
For low-income households, energy burdens are 7.2% nationwide and 10.2% in Atlanta.

6. Conclusions We can: Save water by transforming our power system and
Save water by using less electricity.
At the same time we can reduce energy burdens and breath cleaner air.
