And while lithium has traditionally been controlled by a handful of major global suppliers, spiking demand is changing this landscape drastically.
Universal access to renewably-generated electricity could be within the foreseeable future, with cleaner air and water as the side effects. Better public transportation systems will make life more enjoyable for commuters all over the country, as will a self-sustaining energy economy.
Sam Grobart for Bloomberg: There are 332,519,000 cubic miles of water on the planet. That's 352,670,000,000,000,000,000 gallons just sloshing around out there. Anyone who's ridden or been tossed by a wave has a sense of the kinetic energy contained in our perpetually moving oceans. If we could harness it, it could provide a clean, renewable source of energy. But efforts to turn our oceans into power generators—often in the form of "aqua-mills," windmill technology adapted to water—have foundered on the complexity of their many moving parts in the corrosive and remote environs of the sea. A new approach, developed by a company called Oscilla Power, applies all that kinetic energy to a solid piece of metal instead of using it to turn the blades of an impeller. That creates an alternating magnetic polarity in the metal that can be converted into electrical current. Oscilla's technology, which is nearly solid-state, may prove far more durable than any other ocean-power project, increasing the chance to draw power from our oceans cleanly, meaningfully, and endlessly.

Solar Energy Index Underperforms S&P in Q1 2016
In 2015, the ethanol share of gasoline was 9.9%, and the biodiesel share of distillate was 2.4%.
In September 2015 SunGift Energy completed the UK's first 'solar carports' on the top decks of two multi-storey car parks.
Status report shows that RPS policies likely to remain an important driver for renewables growth.
We asked one customer to model cost savings for us. Note that we didn't pay for this, and it was based on a real bid made in 2015.
CPH Post: Researchers at the University of Copenhagen have discovered a natural process they are calling ‘reverse photosynthesis’. They have observed how the energy in solar rays breaks down rather than builds up plant material, as happens in photosynthesis. Sunlight is collected by chlorophyll, and when combined with a specific enzyme the energy breaks down plant biomass. The resulting product can then be used as a biofuel. By increasing production speed while reducing pollution, the discovery has the potential to revolutionise industrial production. “This is a game-changer, one that could transform the industrial production of fuels and chemicals, thus serving to reduce pollution significantly,” said Claus Felby, the University of Copenhagen professor who headed up the research. “It has always been right under our noses,” he said. “Photosynthesis by way of the sun doesn’t just allow things to grow – the same principles can be applied to break plant matter down, so that the immense energy in solar light can be used so that processes can take place without additional energy inputs.” Cont'd...
Panasonic HIT® panels recently set a world record for conversion efficiency at the research level (laboratory), a full percentage point increase over the previous record.
The desire to halt climate change has drawn researchers around the world to the pursuit of CO2 conversion.
Newly Built Concentrated Solar Power Plants - Time To Consider Flushing and Cleaning as an Industry Standard?
A recent research paper published in Applied Thermal Engineering highlights the importance of defined protocols to effectively flush and clean newly built facilities, which is needed prior to filling the system with expensive fluids, such as solar thermal fluids.
Perovskite solar cells hold much promise for cost-effective solar energy. However, heat stability is an issue, and can significantly limit the solar cell’s long-term efficiency. A team of scientists led by Michael Grätzel’s lab at EPFL has now developed a cesium-containing perovskite solar cell that has achieved efficiency of 21.1%, as well as record-level reproducibility. The work is published in Energy and Environmental Science. By adding cesium, the EPFL scientists, led by postdoc Michael Saliba, made the first ever triple-cation perovskite mixture (Cs/MA/FA). The new films are more heat-stable and less affected by fluctuating surrounding variables such as temperature, solvent vapors or the heating protocol used for the device. But more importantly, they also show stabilized power-conversion efficiencies of 21.1% and outputs at 18% under operational conditions, even after 250 hours. “This is an absolute breakthrough,” says Michael Saliba. “These properties are crucial for commercializing perovskite photovoltaics, especially since reproducibility and stability are the main requirements for cost-effective large-scale manufacturing of perovskite solar cells.” Source AZOCleantech...
Magnetrons will eventually be replaced by solid-state RF power amplifier modules and controllers within the following applications: industrial heating and drying, plasma generation, chemical processing, commercial cooking (restaurants, fast re-heat and thawing) and, last but not least, consumer microwave ovens.
The U.S. Society of Automotive Engineers (SAE) and the International Electrotechnical Committee (IEC) are proposing to develop standardized labels that are color-coded to allow for better identification between lead-acid and lithium-ion batteries.

The IMO FireRaptor provides three forms of Solar Panel Rapid Shutdown to ZERO VOLTS in case of fire or other emergency: Manual Panel Shutdown to 0V Operated from Ground Level, Automatic Panel Shutdown to 0V at >85°C (185°F) Temperature, and an automatic Panel Shutdown to 0V on External Power Loss. The FireRaptor can be installed without any set-up and with any string inverter as its functionality is completely independent. "Plug & Play" style installation using industry standard connectors is easy, whether fitted to new installs or retrofitted to existing projects to upgrade fire safety functionality. Meeting NEC2017's regulation to switch DC current at the PV panel in under 30 seconds, FireRaptor is remains one of the safest and most effective means of isolating DC current at the source, and the only rapid shutdown with a 20 year warranty.
