Cassandra Sweet is a senior writer at GreenBiz, a website that reports on renewable energy and corporate sustainability. Recently, she wrote a piece about the city of St. Louis ramping up its clean energy efforts, with a goal of using 100% renewable energy by 2035, and I asked her to come on my show to talk about it.

We discussed how the legislation was passed despite opposition from Arch Coal and Peabody Energy (both of which are based in St. Louis), but thanks to support from other local businesses like Anheuser Busch and Nestle Purina — as well as Ameren, the electric utility that is also expanding its renewable energy endeavors.

Then we discussed how electric vehicles can be part of this solution, and whether the infrastructure to support them must come before sales can increase. Cassandra also explained how other regions of the US are making similar efforts to use more renewable energy and less coal and oil — including Texas, which has made a major commitment to wind power, thus lessening electric bills statewide.
