Tamil Nadu chief minister Edappadi K Palaniswami has urged Prime Minister Narendra Modi to keep the new Electricity (Amendment) Bill in abeyance till the proposed changes are thoroughly discussed with state governments. In a letter, he said the Bill goes against the rights of states and was detrimental to public interest.

EPS urges PM to put Electricity Bill on hold

A novel sample cell with control of temperature and relative humidity permitted collection of data of excellent quality, enabling unrestrained refinement of all atomic parameters. One of the K atoms in the structure is disordered; very strong anisotropy in three of the four water O atoms indicates partial static disorder, which does not involve the bonded H atoms.

Rb0.21(H2O)yWS2, rubidium hydrate di­thio­tungstate, is a new quasi two-dimensional sulfide. Its crystal structure consists of ordered WS2 layers, separated by disordered Rb+ ions and water mol­ecules. All atomic sites are located on mirror planes. The WS2 layers are composed of edge-sharing [WS6] octa­hedra and extend parallel to (001). The presence of structural water was revealed by thermogravimetry, but the position and exact amount could not be determined in the present study. The temperature dependence of the electrical resistance indicates that Rb0.21(H2O)yWS2 is semiconducting between 80–300 K.

Functional materials are of critical importance to electronic and smart devices. A deep understanding of the structure–property relationship is essential for designing new materials. In this work, instead of utilizing conventional atomic coordinates, a symmetry-mode approach is successfully used to conduct structure refinement of the neutron powder diffraction data of (1−x)AgNbO3–xLiTaO3 (0 ≤ x ≤ 0.09) ceramics. This provides rich structural information that not only clarifies the controversial symmetry assigned to pure AgNbO3 but also explains well the detailed structural evolution of (1−x)AgNbO3–xLiTaO3 (0 ≤ x ≤ 0.09) ceramics, and builds a comprehensive and straightforward relationship between structural distortion and electrical properties. It is concluded that there are four relatively large-amplitude major modes that dominate the distorted Pmc21 structure of pure AgNbO3, namely a Λ3 antiferroelectric mode, a T4+ a−a−c0 octahedral tilting mode, an H2 a0a0c+/a0a0c− octahedral tilting mode and a Γ4− ferroelectric mode. The H2 and Λ3 modes become progressively inactive with increasing x and their destabilization is the driving force behind the composition-driven phase transition between the Pmc21 and R3c phases. This structural variation is consistent with the trend observed in the measured temperature-dependent dielectric properties and polarization–electric field (P-E) hysteresis loops. The mode crystallography applied in this study provides a strategy for optimizing related properties by tuning the amplitudes of the corresponding modes in these novel AgNbO3-based (anti)ferroelectric materials.

The application of thermoelectrics for energy harvesting depends strongly on operational reliability and it is therefore desirable to investigate the structural integrity of materials under operating conditions. We have developed an operando setup capable of simultaneously measuring X-ray scattering data and electrical resistance on pellets subjected to electrical current. Here, operando investigations of β-Zn4Sb3 are reported at current densities of 0.5, 1.14 and 2.3 A mm−2. At 0.5 A mm−2 no sample decomposition is observed, but Rietveld refinements reveal increased zinc occupancy from the anode to the cathode demonstrating zinc migration under applied current. At 1.14 A mm−2 β-Zn4Sb3 decomposes into ZnSb, but pair distribution function analysis shows that Zn2Sb2 units are preserved during the decomposition. This identifies the mobile zinc in β-Zn4Sb3 as the linkers between the Zn2Sb2 units. At 2.3 A mm−2 severe Joule heating triggers transition into the γ-Zn4Sb3 phase, which eventually decomposes into ZnSb, demonstrating Zn ion mobility also in γ-Zn4Sb3 under electrical current.

Across the country, the sale of electric cars is sluggish.

Susanne Whatley: But business analyst Mark Lacter, that's not quite the case in California...

Mark Lacter: Well, comparatively speaking, Susanne.  L.A. and San Francisco alone made up 35 percent of the electric cars sold in the entire U.S. during the first half of the year - 35 percent!  Keep in mind that statewide just 9,700 electric cars were sold in that six-month period, which translates to a little over 1 percent of all car sales in California.  So, they're not exactly lining up around the block, even in a region that's known for its early adopters.  Of course, electric cars were always going to be a tough sell -

Whatley: I've been driving one for about half a year now... and I absolutely love it.  But they ARE expensive, and I'm sure that's a factor.

Lacter: - and that's even after a federal tax credit, but they also require drivers to learn about recharging the battery - sometimes in not-very-convenient places - and, from a design standpoint, most of them don't stand out (one of the automakers that's now out of business had been selling what was a basically plain vanilla Mitsubishi sedan).  Now, the one notable exception is the Tesla - so long as you have at least $90,000 to shell out, and are willing to wait a while to get your car delivered.  In affluent sections of L.A., this is truly the hot car - just 600 or so Teslas have been sold in Southern California during the first seven months of the year.  It's also received rave reviews from all the big automotive publications.

Whatley: And perhaps most surprising of all, Tesla has been making money…

Lacter: That's right, although the stock price is ridiculously overvalued at around $20 billion (that's one-third the market value of General Motors, even though Tesla cranks out all of 21,000 vehicles a year while GM sells almost 5 million).  People seem to love this car almost in spite of it being battery powered, which gets us back to the challenges in trying to sell these things.  Elon Musk, who founded the company (he's also behind SpaceX and he co-founded PayPal), has managed to win over customers because the car itself is so much fun to drive.  The other makers of electric cars - not so much.

Whatley: So, for the folks still on the fence... might it be better to wait until driverless cars become available?

Lacter: That's going to be quite a wait, although all the automakers are working on their versions of self-driving cars.  The Mercedes people just announced plans to launch in 2020 - the same year that Nissan wants to bring out its car - and Google, which has had self-driving cars tooling around California for several years, is looking at 2017.  So, what we're seeing is real, but the question is what sort of real it'll turn out to be.  Certainly, the possibilities are nothing short of revolutionary - you're looking at, potentially, faster commute times because cars will be able to travel closer to one other (reaction times would be faster than with a human behind the wheel); in addition, fewer accidents and injuries (also a function of reaction times).  But, how well the vehicles work once they get beyond the testing phase is anyone's guess.  California does allow self-driving prototypes car for testing purposes, but that's far different than full-scale authorization.

Whatley: What if something goes wrong?

Lacter: That's one of the big concerns - liability, but the real issue is public acceptance.  Already, surveys are finding reluctance to buying a driverless car, or even having them on the road.  That's not a huge surprise considering how novel the concept still is - and all it takes are a few mishaps to affirm the skeptics.  All of which points to a lengthy transition period - not unlike the early days of the passenger plane, when most folks couldn't imagine getting into a flying machine.  Eventually, they got used to them, but it took time.

Whatley: And finally, some thoughts on Cal Worthington?

Lacter: Certainly one of the great showmen in the annals of L.A. broadcasting - Cal Worthington wasn't the first auto dealer to discover the benefits of commercials, but he lasted longer than anyone else, selling more than a million cars (that according to his count), and grossing billions of dollars.  The Worthington ads are sometimes considered the first infomercials - that might be a stretch, but three factors really made it all come together: Southern California's appetite for the automobile, the ease by which Cal could deliver his schtick (remember when he was strapped to the wing of a biplane?), and the fact that there was so much available air time to sell in L.A.. Definitely a legend in his own time.

The U.S. electric power delivery system is vulnerable to terrorist attacks that could cause much more damage to the system than natural disasters such as Hurricane Sandy, blacking out large regions of the country for weeks or months and costing many billions of dollars, says a newly released report by the National Research Council.

A new report from the National Academies of Sciences, Engineering, and Medicine urges Congress, federal and state agencies, and regulatory institutions to significantly increase their support for innovation for what the report’s study committee calls “increasingly clean” electric power technologies – nuclear power, carbon capture and storage, and renewables such as solar and wind. Some of these technologies have seen recent cost and price declines and are cost-competitive in certain locations.

With growing risks to the nation’s electrical grid from natural disasters and as a potential target for malicious attacks, the U.S. Department of Energy (DOE) and the U.S. Department of Homeland Security (DHS) should work closely with utility operators and other stakeholders to improve cyber and physical security and resilience, says a new congressionally mandated report by the National Academies of Sciences, Engineering, and Medicine.

A recent study has assessed the lifecycle environmental impact during the production and use phase of three battery types for plug-in hybrid (PHEV) and full performance battery electric vehicles (BEV). The study indicates that newer lithium-ion (Li-ion) technologies outperform current nickel-metal hydride (NiMH) batteries and identifies processes contributing to 13 environmental impacts

The lifetime environmental impacts of non-electrical consumer products, such as clothes, could be cut by over 40% if consumers maintained them in a more environmentally friendly manner, new research suggests. The study found the impacts of eco-designed products fell significantly when user guidelines were included in the eco-design.

The impact of climate change on electricity consumption is important to both adaptation and mitigation policies. New research has estimated that over the next 100 years climate change could cause up to a 20 per cent decrease in demand for electricity for heating in Northern Europe and up to a 20 per cent increase in demand for electricity for cooling in Southern Europe.

Regulators should establish a process to consider the full lifecycle greenhouse gas (GHG) emissions of electric vehicles, according to a new US study. This would help ensure that vehicle emissions regulations are placed on a sound scientific basis, manufacturers continue to improve the efficiency of electric vehicles, and the full benefit of regulations to limit GHG emissions from vehicles are realised, say the researchers.

A recent study has explored how national regulations and culture, company size and experience with weather incidents have influenced adaptation to climate change in electricity distribution companies in Norway and Sweden. Smaller companies in a strongly regulated environment, with less experience of extreme weather events, find it more difficult to pursue climate change adaption results,

The price of electrical and electronic equipment has risen by an average of 2.19% since the implementation of the Waste from Electrical and Electronic Equipment (WEEE) Directive, new research suggests. Researchers investigated products across 27 EU Member States, with the increases in price reflecting the fact that the consumer is bearing at least part of the cost of e-waste disposal.

Wind and solar energy are effectively limitless resources, but construction of renewable power must compete for a finite amount of land. This study uses a constrained assessment of available land to see whether global energy demand could be fully met by renewable sources. The analysis predicts that by 2070, the world could produce between 730 and 3700 exajoules of electricity per year (EJ/a1) from renewable power, which, even at lowest available land estimates, could meet 2070 electricity needs in most countries.

Electricity consumption fell by 22–27% in low-income households participating in an energy-efficiency programme in Cyprus, France, Malta and Spain, reports a new study. Participants were provided with a range of tools and information to help them curb their energy use, including smart meters and customised reports. The results confirm the value of tailoring information to specific demographic groups.

Recent research suggests that increasing the number of private electric vehicles would have very little impact on electricity consumption in Milan, Italy. However, unless there are suitable regulations, the daily demand for power to recharge the vehicles at peak times could overload the capacity of the electric supply system.

A recent study has assessed the lifecycle environmental impact during the production and use phase of three battery types for plug-in hybrid (PHEV) and full performance battery electric vehicles (BEV). The study indicates that newer lithium-ion (Li-ion) technologies outperform current nickel-metal hydride (NiMH) batteries and identifies processes contributing to 13 environmental impacts.

Two shared electric car schemes, in Berlin and Paris, have been examined by a recent study. Although both schemes are progressive, Berlin's takes an 'inter-modal' approach to encouraging sustainable mobility, because it integrates electric cars into the wider public transport system. The scheme in Paris, however, focuses on cars as the main form of transport.

What drives people to behave in more environmentally friendly ways? A new study explores factors that affect Dutch motorists’ intentions to switch to electric vehicles. The authors found that they could reliably predict the intention to switch by applying a theoretical framework—Protection Motivation Theory—based on perceptions of the threat of environmental damage.

Public subsidies are important in encouraging organisations to trial and expand electric vehicle fleets, according to new research. The study, based on interviews and reports from 17 organisations, found that the opportunity to test new technology was the most important factor in deciding to trial electric vehicles. However, some smaller independent companies chose not to expand their fleet because of the expense.

Hybrid and electric vehicles emit lower levels of carbon dioxide and air pollutants than conventional petrol and diesel vehicles, yet their market uptake in the EU remains limited. New research provides an assessment of the Total Cost of Ownership (TCO) — which combines purchase and operating expenses — of different vehicle types. By comparing historical data on hybrid, petrol and diesel vehicles in three countries (Japan, the UK and the USA), researchers found a strong link between TCO and market share of those vehicles. They also identified a number of ways in which policymakers may promote the adoption of cleaner vehicles through the provision of financial incentives.

Controlling energy demand instead of supply could help solve the problems of variability associated with wind power, according to new research. In the case of Portugal, it was estimated that measures to reduce electricity demand could reduce the peak consumption by 17.4 per cent in 2020.

Researchers have provided a set of guidelines to help policymakers, designers and operators develop sustainable solutions for energy-storage systems for electricity grids. The guidelines cover a range of energy-storage technologies and grid-integration options.

Norway has the highest battery-electric vehicle market share of any country worldwide. A new study investigated the incentives that have persuaded consumers to purchase electric vehicles in Norway, revealing that up-front price reductions (such as exemptions from purchase tax) are the most powerful incentives.

A new study has reviewed the dramatic changes that have taken place over recent decades in ‘network-bound systems’ of electricity grids, water supply and wastewater management. Focusing on case studies in The Netherlands, the study found that consumers are becoming more active participants in the supply of these resources and services.
