we ve been discussing the future of solar energy, wind power and electrical storage, and i;m going to ask who would like to ask a question of any of our clean energy initiatives. hi, i m ajay gambier, - iworkjust around the corner at the grantham institute for- climate change and the environment at imperial college. i would like to ask, i is it a surprise to any i of you that we are now in this world i where we are seeing cost competitive clean energy that can - compete with fossil fuels, or was that, in your mind, - an inevitability, and if so, why? i m going to offer that to danielle. so, danielle? thank you, yes. i think it was inevitable, and one of the reasons why most in this space would say that is that we can see these learning curves of cost reduction over time, over decades of time. in solar, in wind, in battery, in most technical arenas, where the certain doubling, for example, the volume of this technology being put out into the world comes out with a cost reduction. so eac
so the super grid idea, even just regionally connecting within a continent, gives us so much more flexibility and resilience and reliability of our grid and reduces the total amount of capacity that we need to have installed, because we re seeing variation that we can tap into if the sun is not shining here, the wind is blowing there. if it s very hot and sunny here, you ve got hydropower or wind power, in another region. connecting us will be a very big part of that. the second part that s quite related is demand response. so how can those who are transmitting and distributing this electricity get signals back from industry or homes that they can, without the user noticing, reduce the load, either change the, turn off the defrost cycle of the freezer for 15 minutes, not even noticeable. 0r reduce the temperature of a cooling. these are the types of responses that we are going to have to get used to, it s not
to more wind power, more efficient offshore wind, and with every one of these turbines that goes out, you re saving about 50,000 metric tons of c02, which is like taking 11,000 vehicles off the road. wow, that is pretty, pretty impressive. henry, look, i want to turn back to solarfor a second. perovskite is the material you ve been working on. what is it, how does it work, and why is it such an improvement and such a possibility for the revolution of solar power? perovskite is a crystal structure. one of the unique aspects of them is because they re composed of three different irons, we can actually change the composition of these irons and that changes the optical properties and electronic properties of this material. this means instead of using a single material to absorb the sunlight, we can actually tune the perovskite to absorb in different regions and stack these materials on top of each other.
households, and so this is incredibly important in terms of being able to move to more wind power, more efficient offshore wind, and with every one of these turbines but goes out you are saving about 50,000 metric tons of co2, which is like taking 11,000 vehicles off the road. . , , , like taking 11,000 vehicles off the road. . ,, y,y road. that is pretty, pretty impressive. road. that is pretty, pretty impressive. henry, - road. that is pretty, pretty impressive. henry, look, l road. that is pretty, pretty impressive. henry, look, i| road. that is pretty, pretty - impressive. henry, look, iwant to turn back to solar for a second. props kite is the material you have been working on. perovskite. what is it, and why is it such an improvement for the revolution of sova power? improvement for the revolution of sova power? perovskite is a crystal structure. one sova power? perovskite is a crystal structure. one of sova power? perovskite is a crystal structure. one of the sova po
