In 2023, the biggest turbines in the world will start generating electricity off the coast of the UK. Each of General Electric’s Haliade X turbines stands 260m high from sea level and can generate 13MW at under ÂŁ50/MWh (€56/$61). But how big … [Read more...]
U.S. Residential Distributed Solar: still getting cheaper, installation and permitting too, more batteries
John Rogers at UCS reviews the new and comprehensive “Tracking the Sun” report from Lawrence Berkeley National Laboratory which covers both residential and non-residential “grid-connected, distributed” solar PV systems in the U.S. There has been clear progress across the board, including PV module efficiency, system costs, installation and permitting, and the uptake of batteries. For example, median efficiency for modules in residential systems … [Read more...]
