Report: Greenhouse gas emissions from government-owned companies

State-owned enterprises (SOEs)—companies for which 50 percent or more of voting shares are held by a government—play a major role in many of the world's largest economies, particularly in electricity generation, oil and ...

Mini electricity generator made from quantum dots

Machines and electronic devices often generate waste heat that is difficult to utilize. If electricity could be generated from this waste heat, it would offer a means for a clean and sustainable power production: Such a technology ...

Woven nanotube fibers turn heat into power

Invisibly small carbon nanotubes aligned as fibers and sewn into fabrics become a thermoelectric generator that can turn heat from the sun or other sources into energy.
