Literally anything that moves is using energy that can be harnessed. Not just waves rolling toward shore but cars depressing roads, buildings swaying in the wind, and much more. One way to harness it is to create a material that can be woven into the fabric of roads and buildings so that it captures the energy and converts it into electricity. Caitlin McDermott-Murphy at NREL describes research into Hexagonal Distributed Embedded Energy … [Read more...]
China is still playing the long game with its ânew threeâ: solar cells, lithium batteries, EVs
Chinaâs ânew threeâ â or xin san yang â are solar cells, lithium-ion batteries, and EVs. The term harks back to the concept of its âold threeâ that were once the pillars of its exports: clothing, home appliances and furniture.

Rooftop Solar for industry: up to 35% of U.S. manufacturing sectors could supply all their own power
Rooftop solar could supply the complete electricity needs of 5-35% of U.S. manufacturing sectors, explains Matthew Eckelman at Northeastern University who summarises his co-authored paper âTechnical feasibility of powering U.S. manufacturing with rooftop solar PVâ. At present, only 0.1% of industrial electricity demand in the U.S. is supplied by on-site sources of renewable energy. But large, unobstructed industrial rooftops and the declining … [Read more...]
