 Fossil fuels are an absolutely amazing resource. If you really want to think about the entire global population, 7.5 billion people, everybody consuming energy at different rates, and we're growing as a population, countries are industrializing. Fossil fuels provide over 80% of all that energy. So everything that we do in our entire way of life, it doesn't matter if we're buying commercial products, if we want to go traveling, we're buying food at a grocery store. All these things, everything requires energy to do it. Fossil fuels really provide that for us. So the fact that that resource is so abundant and so available to us, also very inexpensive. So what's the issue with fossil fuels? As amazing as they are and as wonderful as they have treated us over the years, we realize there might be some issues coming down the pike. The world has achieved a certain balance to it, and now we're cranking out so much fossil fuels. We're using so many fossil fuels that we might be tipping that balance in the wrong direction. Now in my research group, one of the major projects that we're working on is we're trying to make exactly the same types of molecules that we see in industry, that we use in our cars, that we use in jets, that we use in diesel. We're trying to make the same types of molecules, but rather than getting them from below ground, we're trying to get them from the air that we're breathing. And what are we breathing? Everybody on earth is breathing carbon dioxide, and everybody on earth is breathing water. And so if you think about that, we have carbon dioxide, carbon and oxygen. We've got water. We've got hydrogen and oxygen. If you can do your chemistry well, you can rearrange these bonds and make your hydrocarbons once again. And the real trick in all this is that it is impossible to do that without some type of energy. And if we were just burning coal or burning natural gas to give us the energy to do that chemical transformation, we're not going to win at the end because we're just producing just as much CO2 as we're consuming, if not worse. So what are we trying to do? We're trying to come up with processes that utilize renewable energy, things like wind power, things like solar power, which typically comes in electricity form. How can we use renewable electricity to take carbon dioxide, water, break those bonds apart, reform them as hydrocarbons, and now we can burn them as fuels in a jet if we wish. You could burn the hydrocarbon, and what do you do? You release the carbon dioxide and water again to the atmosphere, which in principle you could keep recycling over and over and over again. So my vision for what the world might look like in 50 years would be quite a bit different for how we use energy and how we produce all the fuels and how we produce all the chemicals and how we handle transportation versus what we do today. And I think the odds of finding that one technology and developing one technology that can do what fossil fuels has and that can compete with fossil fuels and provide all the same benefits but without all the costs, I think those are very long odds. We don't need one solution to fit all. We can come up with many, many different solutions. We're going to need probably at least 20 to 50 different big-time technologies, some of which can contribute 0.3% of the spectrum and some we're going to contribute 15% of the spectrum, let's say. And when you add it all up, we can get to where we need to be for us as a globe to thrive, to continue to flourish as a society, to allow all people on earth to have access to electricity and energy so that they can reach the same quality of life that many of us get to enjoy. These are things that really inspire me every day.
