MIT researchers say climate change could reduce the yield of solar modules. Analysis based on the warming scenarios outlined by the IPCC predicts in some areas the annual energy output of PV systems may fall by up to 50 kWh per kilowatt installed.

A combination of carbon pricing and a renewable portfolio standard for electricity companies in India will be more effective than either measure in isolation to help the nation meet its climate change targets, according to a study by MIT researchers.

As renewable energy development is ramped up to address the climate crisis, negative side-effects should be avoided, especially when technology and resources could maximize the benefits. ‘Techno-ecological’ crossovers could ensure win-win outcomes for solar development and ecosystem and biodiversity conservation.

… and it will be quite an effort. The U.K.’s grid operator, National Grid, released a new report on possible energy system transformation pathways, amidst growing public concern over climate change. Ramping carbon emissions reduction targets up from 80% to 100% prompts technical challenges. These can be overcome but will require full alignment of policy effort and individual awareness and decision making.

While it is often stated only 5% of lithium-ion batteries are recycled, a review of research into the second life and recycling of lithium-ion batteries suggests that is a gross understatement. A new study found almost 100,000 tons of waste batteries were recycled last year – about half of what reached end-of-life.

The car will be road tested at Toyota City in Japan. Solar charging technology for the vehicle will then be further optimized before the vehicle goes on sale.

The head of Mercom Capital says solar has a long way to go before it can stand without policy support. Effective grid parity will only be achieved when the cost of PV electricity factors in the expense of grid upgrades and the storage systems its intermittent nature requires, says Raj Prabhu.

Scientists at Saudi Arabia’s King Abdullah University of Science and Technology have demonstrated a system based on commercially available solar panels which can generate electricity and produce clean, drinkable water from seawater or otherwise contaminated sources.

Copper indium gallium selenide thin film technology is on the fly as conversion efficiency closes in on that of crystalline silicon. The technology can be integrated neatly onto facades of otherwise energy intensive commercial buildings. The potential is huge even if the conversion efficiency retains some limitations.

The 3.3 million U.K. households that get their electricity from E.on will receive only renewable energy. The company referred to a public opinion poll as a motivation for the move.
