In April 2015, Gov. Jerry Brown called on the people of the most populous state to reduce their water use by 25% in response to a punishing four-year drought.
It was an audacious goal, and Californians came close to meeting it. Between June 2015 and April 2016, when restrictions were in effect, residents reduced the amount of water they used by 24.5%.
Now, research has revealed there were some unintended side effects to this massive water-conservation experiment. It turns out that California residents weren’t just saving water, they were saving energy as well.
A lot of it.
