Quote: “”Low-carbon electricity investment driven by solar projects but oil and gas spending still too high to meet climate goals”” The IEA predicts investment in clean energy will reach $2 Trillion in 2024. Quote: “”The warning comes days after a separate IEA report revealed that the world is off track to meet the goal of

Gallium nitride power electronics will replace silicon and will make laptop power adapters smaller than a golf ball and will save major amounts of electricity. GaN devices will waste a lot less power, which will enable power electronics equipment to be made smaller and more efficient. Quote: “”GaN-based power electronics, on the other hand, could

The cost of Lithium-ion batteries is still dropping and sodium-ion batteries use even lower cost materials, so it’s likely that the long duration energy storage – LDES – will not catch up for some time. One LDES is green hydrogen, and hydrogen LDES systems seem to have stagnated, partly due to the falling prices of

That’s great to see! There needs to be more BESS – battery energy storage systems – on the grid to replace all the gas turbine peaker plants that have to supply the grid when the sun sets. Once the grid gets 3 or more times the amount of renewables onto the grid and a lot

This is a simple charge controller that includes a dump load to dissipate excess power from the PV panel. D1 is the reference voltage that feed the 393 comparators, and its forward voltage changes with temperature. It would be better to use a low power LM317 to give a stable 1.25 volts. Instead of a

Article about recycling EV batteries versus using EV batteries for stationary storage. At this time, recycling is not very efficient. Quote: ““Today we are not very good at recovering metals, loosing almost all the lithium, silicon, phosphorus, aluminum, and graphite, while recovering only copper, cobalt, and nickel which are more expensive,” he says.”” This suggests
