Every week, there's a new declaration from a corporation, a city, a state or a utility that they are going "100 percent." But what does that mean?

Hawaii and Maine want to get 100 percent of electricity from renewables by midcentury; California and New York want to get 100 percent from carbon-free sources by that time.

In the utility sector, Xcel Energy is looking at 100 percent carbon-free electricity by 2050, while Green Mountain Power wants 100 percent renewable energy.

Likewise, there are plenty of differences among cities and big corporations. The language may sound similar, but these targets often vary wildly in terms of timing, ambition and complexity.

So this week on The Interchange, we're surveying the range of targets. Which ones matter, what do they add up to, and have they changed what’s politically and technically possible?

Support for this podcast comes from PG&E. Did you know that 20 percent of EV drivers in the U.S. are in PG&E’s service area in Northern California? PG&E is helping to electrify corporate fleet vehicles. Get in touch with PG&E’s EV specialists to find out how you can take your transportation fleet electric.

We're also brought to you by Uplight, the company you once knew as Tendril and Simple Energy.

The goal is still the same: to offer utility leaders a suite of engagement solutions that deliver customer experiences like Amazon and Netflix. Learn more about how Uplight is building an end-to-end product for utility customer engagement.
