The world record for energy efficiency of photovoltaic cells has been broken again. The National Renewable Energy Laboratory (NREL), together with their partner Solar Junction, reported the incredible 44% efficiency achieved through improvement of the already existing multi-junction PV...
Electric vehicle and hybrid electric vehicle battery packs, typically lithium-ion or nickel-metal hydride , are not much like the small lead-acid batteries that are found in petroleum-driven vehicles today. Even the biggest lead-acid battery systems only...
Here at The Green Optimistic, we firmly believe in electric vehicles as the cleanest transportation available and most certainly the future of transportation as we know it. However, we recognize that EVs have their limitations in comparison with...
A new report, released by Pike Research, shows that the market for solar panels built into building roofs and walls will grow from 400MW in 2012 to 2.25 GW in the next five years.
This technology, also known as “building-integrated...
Apple has developed a new technique that allows storing of wind energy directly from the wind turbine in the form of heat, which is then used to generate electricity.
In general, this type of technology is used to convert kinetic...
Clean Energy Collective together with San Miguel Power Association makes available clean energy produced locally for anyone in the area with a 1.1 MW plant.
San Miguel Power Association, Inc. (SMPA), the local electric cooperative, together with pioneer of the...
Much imagination is required to envisage a five star hotel as part of Gaza’s ruins, particularly one constructed using adobe bricks. The building was designed by Algerian-born and –trained Rashid Abdelhamid, a Palestinian architect, the Aldeira Hotel which has...
The Air Resource Board of California accepted the 2014 Honda Accord plug-in hybrid (PHEV) into its new Super ultra low emission vehicle 20 standard (SULEV20), labeling it as the first gasoline-driven vehicle to meet that standard.
The usual SULEV standard...
Light from the sun is made up of a number of different wavelengths ranging from 1 nanometer to 1 millimeter. Solar cells aren't reactive to the whole spectrum, but only a small portion of it, so the rest of...
On March 11, 2011, an earthquake in Northeastern Japan sparked a cascade of failures at the Fukishima Daiichi Nuclear Power Plant. Three of the four reactors there suffered catastrophic meltdown and subsequent explosions, littering the landscape with radioactive fallout....
