Yeah, good question. Good morning. Two-fold, the first one is, the world, obviously, that the world of energy and how energy is generated is going to change over time. And the direction of that is clear. It's going to be renewables, energy is going to become much, much more prevalent part of the future. But it's also not going to be immediate. It's not going to happen in 2022 or '23 and it's going to be slow gradual progress. So, a lot of the things that UOP still does will become relevant, particularly a big part of that business being around gas, natural gas, which we know is the cleanest of the hydrocarbons. So, that's Phase one. So, I think that we got to continue to serve our customer base. And frankly, many of whom will be transforming in terms of how they provide energy to the world. The second part, as we've launched a new business within UOP, Sustainability Technology Solutions business, which is going to become a bigger and bigger and bigger part of the UOP portfolio. And it really has three primary growth levers. One is energy storage, which is economically feasible and viable and we're building and deploying our first prototype of that this year. So, it's not a dream. Two is, 360 degree plastics recyclability, which also we're going to be deploying some technology this year. And then last one, where we really are the pioneers, which is Ecofining, which is going to become a bigger, bigger part of that refining footprint. So, we've got three sort of, this is under one business umbrella and that's going to become our growth engine for the future. So, what I envision happening is potentially longer term, some of the more hydrocarbon-oriented offerings will slowly and I emphasize, very slowly decline, while our Sustainability Technology Solutions business will grow very, very quickly. That's - that sort of how you see that business evolving. That's where we - this is another place we're investing, put our dollars to work and we're excited about the future and the kind of solutions that we have. And as you know, we don't have better scientist anywhere in our company than in UOP when it comes to material science and I'm quite confident that some of these technology breakthroughs will work and will really enable a path to future energy footprint of the world.
