<s>[INST] So if you look forward 30 years, you know, the year 2050 has been labeled by scientists as this, kind of, almost like this doomsday deadline on climate. There's a consensus of scientists, a large consensus of scientists, who believe that if we haven't completely eliminated greenhouse gases or offset them completely by 2050, effectively we're inviting climate catastrophe. Do you believe there is a pathway to avoid that catastrophe? And what would it look like? [/INST] Yeah, so I am not one of the doomsday people, which may surprise you.
I actually think we're on a good path. But at the same time, I want to caution against complacency. So, so long as we are not complacent, as long as we have a high sense of urgency about moving towards a sustainable energy economy, then I think things will be fine. So I can't emphasize that enough, as long as we push hard and are not complacent, the future is going to be great. Don't worry about it. I mean, worry about it, but if you worry about it, ironically, it will be a self-unfulfilling prophecy. So, like, there are three elements to a sustainable energy future. One is of sustainable energy generation, which is primarily wind and solar. There's also hydro, geothermal, I'm actually pro-nuclear. I think nuclear is fine. But it's going to be primarily solar and wind, as the primary generators of energy. The second part is you need batteries to store the solar and wind energy because the sun doesn't shine all the time, the wind doesn't blow all the time. So it's a lot of stationary battery packs.
And then you need electric transport. So electric cars, electric planes, boats. And then ultimately, itís not really possible to make electric rockets, but you can make the propellant used in rockets using sustainable energy. So ultimately, we can have a fully sustainable energy economy. And it's those three things: solar/wind, stationary battery pack, electric vehicles. So then what are the limiting factors on progress? The limiting factor really will be battery cell production. So that's going to really be the fundamental rate driver. And then whatever the slowest element of the whole lithium-ion battery cells supply chain, from mining and the many steps of refining
to ultimately creating a battery cell and putting it into a pack, that will be the limiting factor on progress towards sustainability. </s>
