"For temperatures of up to 200°C, the technology attracting most attention is not the electric kettle but the industrial heat pump. Heat pumps, like refrigerators, move heat from one place to another. In a fridge the heat is removed from the inside (keeping the contents cooler) and dumped outside (making the kitchen a little warmer). Heat pumps, which are becoming increasingly common for domestic heating, take heat from outside and move it inside. Because the amount of energy needed to move heat this way is lower than the amount needed to heat things up directly, this can lead to big energy savings. And as the technology improves and sales increase, prices are falling."

“Walmart aims to reduce emissions from its supply chain by 1 gigaton by 2030 via its Project Gigaton initiative, and it is now extending its buying power to its suppliers, who will be able to group together to buy renewable energy via its Gigaton PPA Program that launched in September. Smaller companies can be priced out of the market for renewable energy, and there are only around 100 corporates buying renewable energy in this way, according to Walmart’s calculations and data from the Renewable Energy Buyers Alliance.”
