Wind turbines are set to become a whole lot better at turning wind into energy after a team of Danish scientists tested a superconducting rotor on a turbine. So, you might be asking: what on Earth is a superconductor and how does it improve wind turbines? A superconductor is a … [Read more...] about Superconductors are about to make wind turbines ultra-efficient

NYC approves law that targets its biggest source of CO2 emissions: buildings
Since the building and construction sector is responsible for around 30 percent of global energy consumption and the greenhouse gas emissions that come with it, decarbonizing our buildings is an essential step for curbing climate change. On Thursday, the city of New York … [Read more...] about NYC approves law that targets its biggest source of CO2 emissions: buildings
These firefly-inspired LEDs are nearly twice as efficient as conventional ones
Imagery from outer space makes it abundantly clear just how many light bulbs are shining in the world every night. If we want to spare the environment and reduce the amount of power these lighting systems consume (while lowering energy costs), creating more efficient light bulbs … [Read more...] about These firefly-inspired LEDs are nearly twice as efficient as conventional ones
Energy hackers
After Chris Dalby found instructions online for track-ing home energy use, he installed a monitor in his house, so he could see how much energy he was consuming at any time. Then he experimented, flipping stuff on and off, to see what used how much energy and how he could save. … [Read more...] about Energy hackers
