Within the next decade, tens of millions of homeowners could find it economically advantageous to invest in solar combined with energy storage, further distancing themselves from their utility. But will they actually sever ties completely? Barring extraordinary circumstances, the economic case for grid defection is still very weak for U.S. consumers. The electricity system offers valuable backup in case a

Back in 2010, Congress directed the National Highway Transportation Safety Administration (NHSTA) to create rules requiring noise generating devices on EVs, PHEVs, and hybrids while operating on electric power. Studies conducted at the time had suggested that such cars were so quiet that they represent a danger to pedestrians, especially the blind. In fact, the National Federation For The Blind

As part of its plan to provide climate aid in the developing world, Japan has expanded the support it provides to the Caribbean countries. Under the Project for Japan-Caribbean Climate Change Partnership, the former will provide eight Caribbean countries $15 million for preparing and designing their Nationally Appropriate Mitigation Actions (NAMAs) and National Adaptation Plans (NAPs). As per the agreements

Several months ago, the team including Thomas Mueller, Marco Furchi and Andreas Pospischil, had already produced an ultra-thin layer of the photoactive crystal tungsten diselenide. Now, the semiconductor has successfully been combined with another layer made of molybdenum disulphide, creating a designer-material that may be used in future low-cost solar cells. With this advance, the researchers hope to establish a

Texas Instruments introduced a new family of digital-to-analog converters (DACs) that enables engineers to increase the accuracy and performance of programmable logic controller (PLC) I/O modules, field sensors and transmitters, and building automation systems, while decreasing overall system size and cost. The DAC8760 family is also the industry’s first to provide simultaneous voltage and current outputs, giving system designers the

Linear Technology Corporation announces the H- and MP-grade versions of the LT8705. This high efficiency (up to 98%) synchronous buck-boost dc-dc controller operates from input voltages above, below or equal to the regulated output voltage. The LT8705 operates over a 2.8V to 80V input voltage range and produces a fixed 1.3V to 80V output, using a single inductor with 4-switch

Using a new method to track the electrochemical reactions in a common electric vehicle battery material under operating conditions, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have revealed new insight into why fast charging inhibits this material’s performance. The study also provides the first direct experimental evidence to support a particular model of the electrochemical reaction. The

scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have discovered a new catalytic system for converting carbon dioxide (CO2) to methanol-a key commodity used to create a wide range of industrial chemicals and fuels. With significantly higher activity than other catalysts now in use, the new system could make it easier to get normally unreactive CO2 to

China continues to play a major role in strengthening renewable energy infrastructure in Africa. The Asian giant has been lending financial and technical assistance to African countries looking to install solar, wind, and hydro power projects. Tanzania has become the latest beneficiary of financial assistance from China, for a 300 MW wind energy project. China’s Export-Import Bank will provide $136
