The Empire State Building, for instance, is powered entirely by wind energy; the small city of Burlington, Vermont is run entirely on biomass, wind, solar, and hydropower; and the tech giant Google has been powering its data centers and office buildings with renewables since 2017.

The truth is that for the past several years, they’ve been trying to cut carbon emissions on what could be termed “Easy” mode. Yes, they buy enough renewable energy to run on clean power all the time, but that energy isn’t necessarily what’s providing the power for their air conditioners and microwaves at any given point in time.
Now, however, some are pushing governments and companies to switch from “Easy” to “Hard.” They want to deploy something called “24/7 clean energy” — a goal that could drive a whole new phase of clean energy use. And they’ve ju... Read more
