Professor Paul Dastoor and his team have been working to create solar cells that can be printed directly onto surfaces like metal sheets, and they are aiming to eventually develop solar cells that can simply be painted directly onto surfaces.

Carbon dioxide emissions fell by 13% in the past five years, because of new energy-saving technologies and a doubling in the take-up of renewable energy, the report compiled by Bloomberg New Energy Finance (BNEF) for the Business Council for Sustainable Energy (BCSE) said.
Nah. It’s because we’re driving less. Look at the VMT chart. The drop in emissions is mainly due to the bad economy, not renewable energy.

… But some companies that essentially live on the Internet are moving facilities to North Carolina, Virginia, northeastern Illinois and other regions whose main sources of energy are coal and nuclear power, the report said. The report singles out Apple as one of the leaders of the charge to coal-fired energy.
Apple immediately disputed the report’s findings, saying that the company planned to build two huge renewable energy projects at its recently opened data center in North Carolina that would eventually offset much of the coal-fired and nuclear energy use.
But in a contrast that is sure to generate debate in the hypercompetitive marketplace of the Internet, the report asserts that a few other companies, including Google and Facebook, have demonstrated much more commitment to shifting some of their electricity demands to renewable sources like wind, solar energy and hydroelectric power.

Floating windmills offshore Japan.
The biggest challenge in erecting floating turbines offshore is ensuring the buoyancy mechanisms are stable, and getting fixed lines to the sea floor which can be extended to depths of 200 meters (656 feet).
