<s>[INST] Let's say 2050 we have this amazing, you know, 100 percent sustainable electric grid made up of, you know, some mixture of the sustainable energy sources you talked about. That same grid probably is offering the world really low-cost energy, isn't it, compared with now. And I'm curious about like, are people entitled to get a little bit excited about the possibilities of that world? [/INST] People should be optimistic about the future. Humanity will solve sustainable energy. It will happen if we, you know, continue to push hard, the future is bright and good from an energy standpoint. And then it will be possible to also use that energy to do carbon sequestration. It takes a lot of energy to pull carbon out of the atmosphere because in putting it in the atmosphere it releases energy. So now, you know, obviously in order to pull it out, you need to use a lot of energy. But if you've got a lot of sustainable energy from wind and solar, you can actually sequester carbon. So you can reverse the CO2 parts per million of the atmosphere and oceans. And also you can really have as much fresh water as you want. Earth is mostly water. We should call Earth ìWater.î It's 70 percent water by surface area. Now most of thatís seawater, but it's like we just  happen to be on the bit that's land. </s>
