The world we live in today runs on batteries. But the lithium ion batteries that dominate the market are expensive and environmentally demanding to extract. The raw materials for lithium ion batteries are scarce and concentrated in a few geographical regions. This places continued pressure on supply chains.
Sodium probably won’t replace lithium in mobile batteries: phones, laptops, ebikes, cars. Sodium is bulkier and less energy dense.
But, a world powered by environmentally friendly forms of energy will have peaks and troughs. Batteries could store grid power and work at night or when the wind isn’t blowing. There are already times in Australia where electricity is absolutely free because the sun is shining and solar cells are generating more energy than the grid needs. With enough batteries, Australia could presumably go 100% renewable.
Idk I’d rock an 80s style briefcase phone.
Could. But both the major parties are corrupted by the fossil fuel industry so there’s little chance.
Also the power companies would like artificially low supply to keep the prices high since most of them hold monopoly anyways.
