44%

The amount of incoming solar radiation that might currently be convertable into electricity, in laboratory experiments.

Solar panels on the nonmilitary market produce electricity with ~14% to ~19% efficiency, said Spiegel.de. Conventional silicium solar panels can’t convert more than 34% of incoming sunlight into electricity. In 2012, Cambridge University researchers said they’d developed a new approach that could improve that by making electricity out of nonvisible light, such as heat. Their two-part system’s components each converted a different section of the spectrum of solar radiation. At least one of the two components is in the form of nanoparticles. The idea of “printing” solar panels that consist of a mix of small particles each specializing in conversion of different light wavelengths is a thrilling one.

“Power-heat connection.” Some German cities are using waste heat from the cities’ relatively low-pollution gas-powered electricity generators to heat private residences.
