Solar was a 24% learning curve rate, meaning for every doubling of solar power volume out in the world, itd be 24% reduction in cost. and as you continue to see volume increase in these technologies you will continue to see cost reduction. thank you so much, danielle. so we are now going to go to scotland, to alastair, who has a question about nuclear energy. hello, today weve got representatives of wind and solar, which are often portrayed as the two examples of clean energy. but there are stil...

Of technologies at scale. it will certainly develop and deliver lower—cost solutions that are good for the individual, but the biggest challenge ahead of us isnt technology, its public acceptance. its support for improved permitting and collaboration on changes to ensure that migration patterns for birds are known, and we dont site wind turbines in those areas or wind farms in that space. but there cantjust be a wholesale rejection of this technology because of the threat of something that wou...

If they can fill the gap for winter power, for instance, in the uk where we use the stored hydrogen, you use that as a power source. so its traditional power stations but using green hydrogen as the power source. thank you. im going to look for another question in the room here at the v&a. hi, my name is shivika from imperial college. i just want to know about the future regarding the airborne wind turbines. what do you think that in the near term there is a future for airborne because google in...

Of us isnt technology, its public acceptance. its support for improved permitting and collaboration on changes to ensure that migration patterns for birds are known, and we dont site wind turbines in those areas or wind farms in that space. but there cantjust be a wholesale rejection of this technology because of the threat of something that would be negative. that collaboration is the real opportunity for us to work together. so its a partnership, really, its you delivering the technologies tha...

Technology being put out into the world comes out with a cost reduction. so each curve will have a different rate of learning. solar was a 24% learning curve rate, meaning for every doubling of solar power volume out in the world, itd be 24% reduction in cost. and as you continue to see volume increase in these technologies you will continue to see cost reduction. thank you so much, danielle. so we are now going to go to scotland, to alastair, who has a question about nuclear energy. alastair? h...

From the industry, and we all need to embrace it, and embrace this change. the technologys there, but if it doesnt get employed and deployed, then its not going to work. thank you. kristian? yeah, i think accepting - what is happening on that side, as henry mentions, is crucial. and then an aspect that. i would emphasise as well is that we have to look at wasting energy - as unacceptable. we cant waste energy in any form of action. i so when the energy is. going to be challenging to harvest at l...

Where its in existence — and then use production of hydrogen or fuels and power gas—fired turbines if we need them. if they can fill the gap for winter power, for instance, in the uk where we use the stored hydrogen, use that as a power source. so its traditional power stations, but using green hydrogen as the power source. thank you. im going to look for another question in the room here at the v&a. hi, my name is shivika from imperial college. i just want to know about the future regarding...

Cells on top of each other. and the perovskite we tune to match perfectly silicon. it absorbs only the visible light and we let the silicon absorb all the infrared. and in doing that we actually fundamentally improve the efficiencies. if we made a perfect perovskite on silicon tandem cell, that would top out at about 45%. so weve fundamentally lifted the ceiling. and if we went one step further to anotherjunction, triple junction, three junctions, that would top out at just above 50%. so what pe...

Use that as a power source. so its traditional power stations, but using green hydrogen as the power source. thank you. im going to look for another question in the room here at the v&a. hi, my name is shivika from imperial college. i just want to know about the future regarding the airborne wind turbines. what do you think that in the near term there is a future for airborne because google investing in airborne wind turbine system, weve seen one — first wind turbine system in germany. so what...

Will be in production, and start to be deployed in the world. so this is all fantastic, this is state—of—the—art technology and engineering that is market ready or nearly market ready. so is the message i should get that you are going to gallop to my rescue when it comes to climate change? that i can carry on with my life as i always have, and everything is going to be fine, because the engineers are going to sort it all out? henry, i want to start with you. is that what i should be taking...
