Scientists give solar PV a paint job

Researchers and Berkeley Lab have discovered a shade of blue – dating back to ancient Egypt – which has impressive qualities they say could reduce building energy consumption and boost solar energy output. Meanwhile, NREL has developed a perovskite cell material that could be applied to a substrate using a paintbrush.

Spatial and temporal specificity: the new high bar for 100% renewables

Google, already 100% renewable powered via PPAs offsets of fossil fuels, is now aiming to make sure they’re clean energy powered 24/7 – even as the sun sets, and winds die down.
