Ian Bremmer discusses the World In (more than) 60 Seconds:

What's happening in Texas?

Speaking of weird weather, my goodness yeah, I didn't know this was coming up here. Yeah, it's cold, right? There's snow. It looks horrible and millions of people without energy and of course that is because the level of infrastructure investment into the Texas grid is well below what it needs to be. There's a lack of integration. Texas' grid largely stands by itself. It is not under the authority of or coordinated multilaterally with broader energy infrastructure. And there has been a lot of investment into renewables in Texas. It is certainly true. They've been very interested in that. Sped up under former Governor Perry but still the vast majority of electricity is coming from fossil fuels. It's coming from coal and mostly oil and gas.
