California continues to lead the US in renewable energy

In 2006, California adopted aggressive legislation aimed at reducing greenhouse gas emissions and boosting renewable energy production throughout the state. And since then, the state has been tracking its progress through its annual California Green Innovation Index report. The ninth report was just released this week and it shows that the state has made some major progress towards its renewable energy goals while hitting a bit of a bump in regards to its emission reductions. Between 2010 and 2015 solar energy generation increased by over 1, 700 percent and renewable electricity accounted for almost 22 percent of all of the state’s electricity generation in 2015. From 2014 to 2015, renewable energy generations increased by over eight percent overall with solar power rising by over 40 percent. But because of the drought, hydroelectric energy generation decreased over six percent. Importantly, the report also shows that with a push towards renewable energy, job and economic growth aren’t hampered. In fact, it’s quite the opposite. Since California’s climate law was passed in 2006, the state’s GDP has increased by nearly $5, 000 per person — which is double the increases the US achieved as a whole. Job growth in California was also stronger than the rest of the country by about 27 percent. These achievements were accomplished all while reducing per capita emissions by 12 percent and carbon-intensity by 4.5 percent. However, while the report shows that the state is doing very well in some areas, it also notes that reductions in greenhouse gases have stalled, falling just 0.34 percent between 2014 and 2015. And those numbers have been leveling out for the last few years. The report attributes the lack of progress in this particular area to cheaper gas prices and increased commute times — which rose nearly three percent — as residents are forced to move further away from their jobs due to the rising housing costs in urban areas. “Transportation sector emissions vastly outweigh other carbon-producing areas of California’s economy, and the recent spike should alert policy-makers that despite our best efforts, more must be done, ” Adam Fowler, an economist at the research firm that put the report together, said in a statement . However, while there’s still some work to be done, the progress the state has made shows that its efforts are largely working and should be seen as a standard for other states and the country as a whole. “The data in this year’s Index shows that developing cleaner transportation options presents both a great challenge and a great opportunity for the state moving forward, ” said Noel Perry, the founder of the nonprofit group Next 10, which released the report. “Finding a way to reduce emissions by 5 percent each year in the coming decade will require innovation. Fortunately, that’s something California has proven it knows how to do.” Source: Next10 (1) , (2) , (3)

California will start charging electric vehicle fees in 2020

While some states are still offering incentives for electric vehicle buyers, California will soon become the biggest state to start charging fees for EV ownership. California is estimated to account for about half of the country’s EV sales, so the state is keen on recuperating some of the money it won’t be making from gasoline taxes. The fees will take effect starting with 2020 model year plug-in vehicles, Autoblog reports . Those vehicles will have one-time $100 registration fee upfront, followed by and annual registration fee that varies based on the market value of the vehicle. On the low end, the fees are $25 for a vehicle valued at less than $5, 000, but anyone with a $60, 000-plus plug-in vehicle will be paying $175 per year to keep their tags up to date. On the other hand, California has the highest gas prices in the country , and even on the high end, those registration fees will end up costing less than three or four tanks of gas. Internal combustion fans won’t be getting a break either: California’s gas tax will hit 30 cents per gallon by November 2017. All told, California’s EV fees are expected to generate $52 billion over 10 years, which will be put back into the state’s budget for infrastructure repairs. Elsewhere in the US, EV fees have already caught on. According to the Sierra Club , 10 states plus Washington, DC already have similar fees while eight others are currently considering similar legislation. Via: Autoblog Source: California Senate

Over 8,000 Uber, Lyft drivers fail new Massachusetts background check

More than 8, 000 Uber and Lyft drivers have been denied licenses to operate in Massachusetts under a new, stricter state background check law , according to the Boston Globe . The most common reason? Issues with the driver’s license status, including suspensions. Under the new law, which went into effect in January, drivers for ride-hailing companies must undergo a two-part background check, one from the companies and one by the state. Out of 70, 789 applicants, 8.206 drivers were rejected, according to a state review. Hundreds were turned down because they had serious crimes on their record, including violent or sexual offenses. Others had drunk or reckless driving offenses. 51 applications came from alleged sex offenders. Uber has faced criticism in the past over its handling of background checks. District attorneys in Los Angeles and San Francisco filed a civil suit against the company in 2014, claiming it failed to unearth the criminal records of 25 drivers in those areas. But, both Uber and Lyft point out that the Massachusetts background check delves much deeper into a person’s history than theirs do, which is unfair to drivers who are trying to turn their lives around. “Under Massachusetts law, Lyft’s commercial background check provider, like all consumer reporting agencies, is legally prevented from looking back further than seven years into driver applicants’ histories, ” Lyft told the Boston Globe in a statement. “The state does not face the same limitation, which likely explains why a small percentage of our drivers failed the state’s background check while passing ours.” “Thousands of people in Massachusetts have lost access to economic opportunities as a result of a screening that includes an unfair and unjust indefinite lookback period, ” Uber said in its own statement. “We have an opportunity to repair the current system in the rules process so that people who deserve to work are not denied the opportunity.” Massachusetts is hardly the first state to push back against ride-hailing companies. Now that Uber and Lyft are becoming ubiquitous across the country, and with self-driving cars on the horizon, over 30 states have passed regulations to tackle some of the companies’ thornier issues.

Scientists make battery that runs on air and carbon dioxide

Researchers at Penn State University have potentially come up with yet another way we could create energy from all that nasty carbon dioxide we pump into the atmosphere. They’ve developed an inexpensive flow cell battery that uses mostly water solutions containing either dissolved CO2 or dissolved normal air — the technical name for the dissolving process is called sparging, just FYI. Because the liquids contain different concentrations of CO2, they have different pH levels, and it’s this imbalance that generates electricity. In a flow cell battery, two liquids are separated by a membrane that doesn’t allow them to mix, but does permit the flow of ions. As ions are exchanged between the denser CO2 solution and normal air solution, the voltage changes at the manganese oxide electrodes in either tank. This stimulates the flow of electrons between the two connected electrodes and voilà : electricity. When the ion concentrations have normalized, you can effectively recharge the battery by refilling each tank with the opposite solution, reversing the flow of electrons. The Penn State scientists were able to do this over 50 times before seeing a drop in performance. Using CO2 in a flow cell battery isn’t an entirely new idea, but this version has an average power density of 0.82 W/m2 — nearly 200 times higher than anything developed previously, according to the researchers. Other CO2-based fuel cell systems are capable of much more, but they are also much more complicated, using other energy dense fuels and requiring high temperatures to operate. Penn State’s battery, on the other hand, works at room temperature and uses inexpensive materials and processes. Even so, the team admit it may not be economically viable to make use of their research on a large scale just yet. The dream, though, would be to integrate these batteries into fossil fuel power stations, repurposing their CO2 emissions to make even more energy. While more work needs to be done to improve performance and viability, anything that can make light of a bad (and worsening) situation can only be a good thing.

New York approves a 90 MW wind farm off the coast of Long Island

The Long Island coastline. (credit: Stanley Zimney ) On Wednesday, New York Governor Andrew Cuomo announced that the state had approved a 90 MW offshore wind farm to be installed off the coast of Long Island. That would make what will be called the South Fork Wind Farm the biggest offshore wind farm in the US. The announcement comes just a month after Block Island, a facility off the coast of Rhode Island , became the first ever commercial offshore wind farm in the US to transmit electricity in late 2016. Deepwater Wind, the company that installed the turbines off Block Island, will also be supplying the turbines for South Fork. In a press release, the New York governor’s office wrote that the turbines will be placed 30 miles southeast of Montauk and “out of sight from Long Island’s beaches.” The press release added that South Fork will provide electricity for 50,000 Long Island homes. Two weeks ago, Governor Cuomo announced that New York would commit to installing 2.4 GW of offshore wind by 2030. That comes just as the state announced that Indian Point, a 2 GW nuclear energy facility just north of New York City, would close by 2021 . The state of New York celebrated the closure of Indian Point, claiming that the plant was unsafe and too close to a major metropolitan area. But critics of the move said it would be difficult for New York to replace all of that greenhouse-gas-free energy with renewable energy. Read 4 remaining paragraphs | Comments

Squid protein makes textiles self-healing

You might be able to repair your ripped jeans one day just be adding water, thanks to a breakthrough from Penn State researchers. Based on its earlier research on self-healing plastics , the team turned squid teeth proteins (yep) into a liquid form using yeast and bacteria, then used it to coat cotton, wool and other fabrics. If the material is torn, you just need to put the edges together, apply warm water and it magically “heals, ” as flexible and strong as before — even after being laundered. “Fashion designers use natural fibers made of proteins like wool or silk that are expensive and they are not self-healing, ” said Penn State Professor Melik C. Demirel. “We were looking for a way to make fabrics self-healing using conventional textiles. So we came up with this coating technology.” The proteins can be used to fix regular, non-coated fabrics by adding water, or applied to threads before the material is even made. The technique isn’t perfect — there are visible seams — but it’s still better, stronger and easier than any sew job I’d attempt. As the garments can be self-healed by water, throwing them in the wash would also fix small tears or other defects. It sounds great for klutzy clothes owners, but the research, supported by the US Army and Navy research arms, isn’t just aimed at consumers. Dermirel thinks the substance could be adapted to create clothing that protects soldiers, farmers or industrial workers by neutralizing toxic chemicals. “If you need to use enzymes for biological or chemical effects, you can have an encapsulated enzyme with self-healing properties degrade the toxin before it reaches the skin, ” he said. By adding anti-bacterial properties, it could also be used in medical dressings or mesh clothing to reduce infection risks. The team now needs to figure out how to create the proteins without using actual squid or their teeth, and plans to further torture-test the repaired materials. “The next step would be to see if clothes can self-repair when we pour the liquid into a washing machine, like you would a detergent, and apply water and heat, ” Demirel tells CNN .
