There's an efficiency aspect of how much of the sun hitting the solar panel can be converted and that's going up every year. But there's a kind of a limit to how high that can naturally be be captured anyway. A heat pump is actually really bizarre when you look at the efficiency because if you've got my bill them fan he's the giving me one down here and it's quite efficient like it's over 90% efficient so it's used out. The same concept with a coal power plant that you're actually physically losing two thirds of that energy that'sgoing up going up a chimney in the form of heat.
Dave Jones is the Head of Data Insights at Ember, a think tank helping shift the world from coal to clean energy—rapidly.
Dave joined me to discuss the energy transition, going into detail about the impact of coal, gas and oil before comparing our renewable options. He reveals the nations around the world leading the renewable race, the supply chain weaknesses that need to be addressed, and, as ever, the necessity of energy demands vs desires.
“We need to get beyond just thinking about coal and gas power, and to be thinking about like the extra electrification of all the other sectors coming on, because that's gonna hit us really hard in the next few years….
“It's not hitting us at the moment, we’re seeing it fall at the moment. But we know that we’re going to get this big increase coming in the next few years, and trying to keep an eye on that, trying to make sure that we’re putting that into our calculations —Christ, we’re going to have to build an awful lot of clean electricity for all of this.”
