A new report supports the idea that underground mines can be transformed into energy storage facilities, adding the possibility of on-demand, carbon-free power to energy grids.
Green PCs Get an A for Effort
Conventional wisdom has it that PCs and electronics are just bad for the environment – think nasty chemicals, extreme water use, and e-waste. Manufacturers are making progress, with more on the horizon.
