Yes, thank you.
The basic reality of it is that fossil fuel demand by human beings is growing today on earth, and that it's very, basically, impossible to replace fossil fuels. We need to reduce emissions, so carbon capture and storage provides the means to do that, but it's also the case that industries like cement, steel, power generation and ammonia fertilizer production essentially use fossil fuels to produce those products, and carbon capture and storage can be equipped to reduce the emissions from the use of fossil fuels in those particular situations.
The basic reality of it is that we need to meet energy demands from eight billion people, and we can see what happens if that starts not happening. Right now, globally, we have a very large fertilizer shortage. Ammonia fertilizer production in Europe was required to be reduced as a result of insufficient natural gas over the course of the past several months. Now we have an ammonia fertilizer problem globally.
These unintended consequences to eliminating fossil fuels can show up in various places, including in the production of food and in the production of solar panels. Solar panels are made from coal. The cost of solar panels has increased significantly in the last 12 to 18 months because coal prices have skyrocketed.
The point I'm simply making is that the energy system is a complex system, and ensuring that we have sufficient amounts of energy is how we will be able to reduce emissions. It costs energy and it costs capital and materials to reduce emissions, so this is a complex problem, and carbon capture has an important role.
I could talk more about how we finance that, but I'll pause there with respect to the general question.
