Originally published on Cleantechnica. By Nicholas Brown. A battle has been brewing between utility companies and the rooftop solar industry in California, and, of course, it’s about money. They compete with each other because rooftop solar systems enable people to purchase less power from utility companies, but the companies still have a leg to stand…
Originally published on Cleantechnica. By Joshua S. Hill. It is quite possible that daylight saving time is one of the most unambiguously contentious issues of our time.

Originally published on Cleantechnica. By James Ayre. Thin-film solar cells may soon possess the ability to absorb a notably larger portion of the light that strikes them, thanks to the recent development of a “superabsorbing” design by researchers at North Carolina State University. As well as improving the light absorption efficiency of thin-film solar cells,…
People have driven more than 1 billion miles in Tesla, Nissan Leaf, and Chevy Volt electric vehicles. This signifies that the public, and the electric vehicle manufacturers now have over 1 billion miles of EV driving experience and test data. This is critical to the electrification of the automobile, as early adopters are putting EVs…

Tesla Motors Takes Another Step Forward Tesla Motors’ electric vehicles are among the best-selling EVs, and that means they need many batteries to build their cars. The company intends to construct an enormous ‘Gigafactory’ (possibly in Nevada) which could produce up to 500,000 electric vehicle batteries annually. The batteries are to be constructed from the…
Juan Pablo Montoya is a racing legend who has won the Indy 500, the Monaco GP, the Daytona 24, and he raced in NASCAR. This became apparent when he posted a picture of himself at the wheel of a Tesla Model S on Facebook, which stood out especially because of its 17 inch LCD screen. Now,…
Netflix created an amusing spoof of drone delivery services called Drone2Home. [yframe url=’http://www.youtube.com/watch?v=ucz3JpvDQjk’]On a serious note, drones have the potential to deliver packages very efficiently, both in terms of speed and energy usage. Drones demonstrated by Amazon and the UAE are the lightest, and smallest vehicles to deliver packages yet. Instead of using one large…
In 2001, Dale Earnhardt died in a devastating accident during a NASCAR race at the Daytona International Speedway in his number 3 car. The number 3 car was retired since then. Now, it has returned with an ethanol-powered engine. It was raced at the Daytona 500 on February 22, 2014 by Austin Dillon, the grandson…

The average household incurred a gas and electric bill of $288 in Ohio, and $276 in Kentucky. I suspected there would be at least a…
Climate change has many potential implications, but one of the scariest possibilities could intensify them all, and catastrophically. It is thermal runaway. Thermal runaway is defined as a situation in which heating causes conditions, or a domino effect (as I like to call it) which causes further heating. There are multiple thermal runaway scenarios to…
