05 Jun 2014: Coating for Roof Tiles Could
Help Clear Smog-Causing Air Pollutants

Engineering students have created a roof tile coating that, when applied to an average-sized residential roof,

breaks down the same amount of smog-causing nitrogen oxides per year as a car driven 11,000 miles makes. If applied to one million roofs, the titanium-dioxide based coating, which costs roughly $5 per roof, could clear 21 tons of nitrogen oxides each day, the team calculated. That could put a noticeable dent in atmospheric levels of the pollutant; in Southern California, for example, an average of 500 tons of nitrogen oxides are emitted daily. The team, which was recently recognized in a U.S. Environmental Protection Agency student design contest, showed that their tiles could remove 88 to 97 percent of nitrogen oxides in laboratory tests — a feat that other roof tile prototypes have not demonstrated.

Those 95 developing nations today make up the vast majority of the 144 countries with renewable energy support policies and targets in place. The report credits such policies with driving global renewable energy capacity to a new record level last year — 1,560 gigawatts, up 8.3 percent from 2012. More than one-fifth — 22 percent — of the world's power production now comes from renewable sources. Overall, renewables accounted for more than 56 percent of net additions to global power capacity in 2013, the report says. Although financial and policy support declined in the U.S. and some European countries, China, the U.S., Brazil, Canada, and Germany remained the top nations for total installed renewable power. China's new renewable power capacity surpassed new fossil fuel and nuclear capacity for the first time, the analysis found.

02 Jun 2014: New U.S. Coal Plant Rules
Could Lead to a Steep Drop in Emissions

The Obama administration today unveiled a sweeping new plan that aims to cut carbon dioxide emissions from the nation’s 600 coal-fired power plants by roughly a third. Gina McCarthy, administrator of the U.S. Environmental Protection Agency, said the new rules would give states maximum flexibility to achieve the goal of reducing power plant emissions 30 percent below 2005 levels by 2030. Hundreds of coal-fired power plants are expected to close under the EPA plan. But rather than immediately shutting down plants, states would be allowed to reduce emissions by making changes across their electricity systems — by installing new wind and solar generation or energy-efficiency technology, continuing to expand the use of natural gas, and by starting or joining state and regional “cap and trade” programs. “There is no one-size-fits-all solution ... so each state’s path can be different,” said McCarthy. The proposed regulations could be held up by legal challenges. Obama administration officials said the rules would lift the U.S. into a clear global leadership position on combating global warming.

30 May 2014: New Battery Technology
Could Offer Cheap Renewable Energy Storage

New battery technology that uses cheaper and safer materials to store large amounts of energy may soon enable utility companies to use more renewable power,
Enervault iron-chromium flow batteries
Iron-chromium flow battery technology
according to MIT Technology Review. The new device is a type of flow battery, and it uses liquid materials that rely on iron-chromium chemical reactions to store energy. California-based startup Enervault, developer of the new battery, figured out how to use materials that had been tried in batteries decades ago; Enervault overcame a key technical challenge that had caused the earlier batteries to quickly degrade. The new battery is large — it can store one megawatt-hour of electricity, or enough to run 10,000 100-watt light bulbs for an hour — and the materials last more than 20 years, according to its developer. Although the battery is inefficient compared to conventional batteries — it loses 30 percent of the energy used to charge it — it is still economically viable, the company says. The iron-chromium flow battery costs 80 percent less than vanadium flow batteries, a competing technology. The batteries are currently in use at a small power plant near Modesto, California.

dioxide emissions by an order of magnitude. The E-Fan aircraft has two, 30-kilowatt electric motors powered by a series of lithium-ion batteries in the wings of the plane, as well as a 6-kilowatt electric motor in the wheel to provide extra power during takeoff and taxiing. Despite incorporating highly energy-efficient and aerodynamic design elements, however, the E-Fan has only a one-hour range and cannot leave the vicinity of the airport. Airbus says that future designs will rely on electric-hybrid engine technology and that by 2050 such airplanes should be able to accommodate 70 to 80 passengers on a three-hour flight. The plans were spurred, in part, by the European Union's Flight Path 2050, which aims to reduce the aviation sector's nitrous oxide emissions by 90 percent, noise pollution by 65 percent, and carbon dioxide emissions by 75 percent by 2050. "It's a very different way of flying," said Jean Botti, a technology officer at Airbus Group, "absolutely no noise, no emissions."

"water wheel" gathers garbage floating in the Jones Falls River, which runs through the city to the Baltimore Inner Harbor, and deposits it in a large dumpster so the trash can be hauled away. Two large booms funnel debris toward a conveyor belt powered by the wheel, which itself is powered primarily by the flowing river. When the flow isn't strong enough to turn the wheel, water pumps, run by solar panels lining a canopy over the wheel, turn on and push water up to spin the wheel. The water wheel was designed to handle the heavy debris and larger pieces of trash that the river often carries, said its designer, Baltimore-based Clearwater Mills. It began operating earlier this month and cost $750,000, with $500,000 of that contributed by the Maryland Port Administration, Co.Exist reports.

Stanford has become the first major U.S. university to divest its shares in coal-mining companies from its endowment funds, lending support to a growing nationwide movement calling for universities and

pension funds to drop investments in fossil fuel companies. Citing guidelines that allow trustees to weigh whether “corporate policies or practices create substantial social injury” when choosing investments for the university's $18.7 billion endowment, the board decided, after five months of deliberation, to purge stakes in up to 100 companies worldwide that derive profits primarily from coal mining. A Stanford spokeswoman said that coal companies constitute a small fraction of the university's total endowment investments, “but a small percentage is still a substantial amount of money." Board members said their decision was made partly because coal is the most carbon-intensive of any major fossil fuel and that less carbon-intensive energy sources are available.

29 Apr 2014: Exxon Mobil Arctic Project
Possibly At Risk Over Russia Sanctions

Exxon Mobil's development of a Russian Arctic oil project valued at nearly $900 billion is at risk following recent U.S. sanctions on Russian officials as a result of Ukraine's ongoing political crisis, Bloomberg News reports. Exxon Mobil has partnered with the Russian state-controlled oil company OAO Rosneft to drill an oil-rich geological structure known as Universitetskaya, which contains an estimated 9 billion barrels of oil, valued at $900 billion at current market prices. Rosneft's CEO, Igor Sechin, a longtime member of Russian President Vladimir Putin's inner circle, was sanctioned by the U.S. yesterday, exposing the partnership with Exxon Mobil to additional scrutiny. Exxon Mobil and Rosneft are set to invest an estimated $600 million in drilling at the site in the Kara Sea, which would make the project Exxon's most expensive to-date. A U.S. Treasury official said yesterday that U.S. companies can still do business with Rosneft, but some analysts say Russian companies could become wary of working with Western corporations in the future. Exxon said last week that the project is on schedule.

from a non-profit group. Nuclear power — currently the only major zero-carbon, around-the-clock baseload power source — supplies 19 percent of U.S. electricity and is key to meeting President Obama's pledge to reduce emissions 17 percent below 2005 levels by 2020, according to the Center for Climate and Energy Solutions. The economic viability of the 100 nuclear reactors in the U.S. is worsening, the report says, because of the abundance of cheap natural gas and rising wind energy production. A carbon tax or some form of carbon trading — for instance, requiring coal-fired plants to purchase and blend their electricity output with nuclear power — will be essential to keeping nuclear plants from closing before the end of their lifespans, the report contends. Four power companies recently announced the early retirement of five nuclear reactors, which constitute more than 4 percent of U.S. nuclear capacity, the group says.

according to Dutch turbine maker Tocardo International BV. Run-of-river hydropower stations redirect part of a waterway through a diversion to spin turbines and generate electricity. Run-of-river is considered a more benign type of hydropower than large dam projects because it is a smaller-scale technology that doesn't create large upstream reservoirs that flood ecosystems and disrupt a river's natural flow. Some conservation groups are concerned that problems with migratory fish passage and other environmental issues could outweigh the power-generating potential of run-of-river hydro projects. The company implemented its first project to harness tidal streams at Den Oever, Holland, and it has been operating for five years.

04 Apr 2014: Solar Panels Could Beam Power
From Space Down to Earth, U.S. Navy Says

Researchers from the U.S. military are developing technology that would harvest solar energy in space and beam it down to Earth, according to the Naval Research Laboratory. Although the concept seems futuristic, the
Space solar satellite concept
Navy is currently testing two prototype designs, both of which combine solar panels with electronic components that convert the energy to radio waves and transmit it to Earth. Eventually, engineers plan to use robotic vehicles to transport the panels to space and assemble them into a 1-kilometer wide satellite orbiting the planet. Theoretically, harvesting solar energy in space is more efficient than on Earth, because panels can collect sunlight around the clock and regardless of weather conditions. The U.S. military, currently the world's largest oil consumer, is eager to develop the technology to save money on fuel and simplify military deployments. But the private sector also has plans for the technology: California utility company Pacific Gas & Electric plans to buy space solar power by 2016.

27 Mar 2014: Wind Turbine in a Blimp
Can Bring Power to Remote Locations

A Massachusetts company will soon deploy a portable wind energy system using a conventional turbine blade inside a cylindrical blimp that floats about 1,000 feet above the ground, drawing on the stronger winds at that altitude. The Buoyant Airborne Turbine (BAT), developed by Altaeros, is designed to be used in off-the-grid locations where importing diesel fuel or other energy is expensive. The company recently announced a $1.3 million demonstration project in Alaska that will supply power to about a dozen homes. Altaeros says it is also working on deals to install projects in remote locations in Canada and Australia. The BAT, made of industrial fabric, sends power back via high-strength tethers that hold it to the ground. Altaeros is one of several companies developing wind turbines that hover above the earth or fly, including Makani, which has invented a turbine that looks like a flying wing. Makani was acquired last year by Google X.

The consumer giants' new policies go beyond standards set by the industry's main certification body and include provisions to protect wildlife-rich rainforests, carbon-dense peatlands, and the rights of local communities. Environmental groups are welcoming the commitments, though some believe the companies' pledges should go further. The Union of Concerned Scientists questions General Mills' definition of "high carbon stock" forests, while Greenpeace is urging Colgate-Palmolive to move implementation up to 2015 from 2020. Environmental groups are hopeful that new commitments will pressure Proctor & Gamble, the last remaining consumer products giant without a similar pledge, to adopt deforestation-free palm oil policies.

21 Mar 2014: Koch Brothers Biggest Lease
Holders in Alberta Tar Sands, Report Finds

The largest lease holder in Canada's oil sands is a subsidiary of Koch Industries, the conglomerate that is the source of the fortune owned by the controversial conservative political donors, Charles and David Koch. The Koch's holdings in the tar sands were disclosed by an activist group that analyzed mineral records of the Alberta government. The Koch subsidiary holds leases on at least 1.1 million acres in the northern Alberta oil sands, which span roughly 35 million acres; other industry experts estimate the total Koch holdings could be closer to 2 million acres. That puts Koch Industries ahead of energy heavyweights Royal Dutch Shell and Conoco Phillips, both of which lease significant acreage in the oil sands. The findings are likely to inflame the debate surrounding the proposed Keystone XL pipeline — which would transport tar sands oil to refineries in Texas — although the Koch's company has not reserved space in the pipeline. Activists argue that the Kochs do have a stake in the outcome of the Keystone XL battle because the pipeline would drive down crude oil transportation costs, benefiting all lease holders.

York. Solar City will station salespeople in 60 stores throughout those states to pitch the benefits of their 20-year solar contracts directly to consumers, and Best Buy will take a cut of the sales. Based on a homeowner's utility company and monthly electric bill, Solar City representatives will be able to quickly give potential customers an estimate of the costs and savings associated with a solar lease. Leasing enables a homeowner to avoid the large upfront costs associated with purchasing and installing solar panels by spreading those investments over a 20-year lease and locking in a set rate for electricity generated by the panels. Residential solar installations have accelerated in recent years due largely to the popularity of leasing programs, with 2013 showing the fastest growth ever.

11 Mar 2014: 'Space Frame' Wind Tower
Allows Turbines to Be Built in Remote Places

New wind power technology could bring turbines to hard-to-reach locations, according to engineers from General Electric. The company has developed a new type of wind tower, dubbed the "Space Frame Tower," consisting of metal latticework wrapped in weather-resistant fiberglass. Unlike conventional steel tube wind towers, the latticework can be bolted together on-site, which means the tower's framework can be transported using standard shipping containers and trucks, allowing taller wind towers to be installed in locations previously inaccessible to the longer trucks needed to transport conventional towers. The Space Frame Tower also has a five-leg base that's wider than conventional towers, increasing stability and ultimately allowing it to reach heights up to 450 feet — an advantage at sites where higher turbines can reach stronger winds. A 318-foot tall prototype is up and running in Tehachapi, California, with a 2.75 megawatt turbine nearly 400 feet wide.

10 Mar 2014: Arsenic Remediation Project
Will Begin Decontaminating Water in India

New technology that removes arsenic from drinking water is set to be deployed on a large scale in India, according to researchers from Lawrence Berkeley National Laboratory and an India-based water technology company. The device removes arsenic by passing electricity through steel plates submerged in a water reservoir. The electric current causes the plates to rust more quickly than they would under normal conditions, and the rust chemically binds to arsenic in the water and sinks to the bottom of the reservoir. The precipitated sludge can be removed from the tank, rendering the water safe to drink. Notoriously high levels of arsenic, a tasteless and odorless contaminant, naturally occur in groundwater sources in India, Bangladesh, and even California's Central Valley. Long-term exposure can cause cancer and severe damage to organs. A commercial plant is set to begin operations in West Bengal, India, this year and researchers estimate the drinking water can be sold for as little as eight cents per gallon.

Of the 10 cities surveyed, residents of Boston, home of the Zipcar company, were most aware of car-sharing programs. Young people and, surprisingly, households with children were least likely to own their own cars, the survey said. Roughly half of the people who had tried car-sharing had already decided not to purchase or lease their own car, and did not plan to do so in the future. Rather than environmental concerns, nearly 60 percent of interviewees said cost and convenience led them to participate in car-sharing.

"We found that when wind turbines are present, they slow down the outer rotation winds of a hurricane," said Stanford engineer Mark Jacobson, who led the research. "This feeds back to decrease wave height ... which in turn slows the winds of the entire hurricane and dissipates it faster." For Hurricane Katrina, a massive turbine array could have slowed wind speeds by 58 percent and storm surge by 79 percent, and for Sandy wind speeds could have been cut by 14 percent and storm surge by 34 percent, according to findings published in Nature Climate Change.

Since then, production has only intensified in Wyoming, a leading state in the U.S.'s unconventional oil and gas boom. The mapping effort, a first step in determining how oil and gas drilling operations impact wildlife and ecosystems, focused on southwestern Wyoming because it not only has some of the nation's largest natural gas reserves, but also because the region has high-quality wildlife habitat and encompasses a major portion of the country's remaining intact sagebrush steppe.

Other types of rewritable papers have been developed, but they are all more expensive and energy-intensive to produce, and some versions use inks that pose environmental and safety hazards. The new system costs less than 1 percent of standard inkjet printing, the researchers estimate, primarily because ink cartridges are expensive. The researchers found they could refill cartridges with water and use them, along with the rewritable paper, in typical desktop printers. Print on the rewritable paper is only visible for about 22 hours, or as long as it takes the paper to dry completely. The scientists note that, while 90 percent of business information is retained on paper, most printed documents are read only once before being discarded.

12 Feb 2014: Despite Costs, Most Americans
Want Action on Climate Change, Report Finds

A large majority of Americans — 83 percent — say the U.S. should make an effort to reduce global warming, even if those efforts have economic costs, according to a new report from the Yale Project on Climate Change Communication. As many as 56 percent of Americans would be willing to pay an extra $100 each year if their power company would generate 20 percent of its electricity from renewable sources. Corporations and industry should be doing more to stave off climate change, according to 65 percent of people interviewed in a national survey, and 61 percent believe individual citizens should also be taking a more active role. Many of the survey's findings are similar across Democratic and Republican party lines. Tax rebates for energy-efficient vehicles and solar panels are popular among people aligned with both parties, for example, as well as funding renewable energy research and regulating carbon dioxide as a pollutant. And people from both parties are generally supportive of ending all fossil fuel subsidies, although Democrats (67 percent) are more supportive of that policy than Republicans (52 percent).

31 Jan 2014: U.S. State Department Report
Boosts Prospects of Keystone XL Pipeline

In a long-awaited report, the U.S. State Department has concluded that the carbon-heavy oil from Alberta's tar sands will be extracted whether or not the Keystone XL pipeline is built, improving the prospects that the highly controversial project will be built. In an environmental impact statement that was six years in the making, the State Department concludes that the process of extracting and burning tar sands oil creates 17 percent more greenhouse gases than traditional oil, but that the heavily polluting oil will be brought to market with or without the pipeline. "It's unlikely for one pipeline to change the overall development of the oil sands," said a State Department official. If completed, the pipeline would carry 830,000 barrels of oil a day from Alberta to refineries on the coast of the Gulf of Mexico. President Obama will make the final decision on the Keystone XL pipeline and he vowed last year that he would approve the pipeline only if it would not "significantly exacerbate" the problem of carbon emissions. Environmental activists such as Bill McKibben of 350.org have said it would be "game over" for the climate if Keystone XL is built.

More than 1,200 EVs are being sold in Norway per month thanks to incentives that include free electricity for recharging, lower sales tax rates, waived tolls, free parking, insurance discounts, and permission to drive in bus lanes, which are less crowded. The EV rush is expected to slow, however, as bus lanes become more crowded, and the government plans to end financial incentives once 50,000 EVs are registered, which could occur by 2016.

Aiding and Democratizing Research

When biologist Caren Cooper carries out her avian studies, she’s aided by thousands of assistants, none of whom are paid for their work.

to her research projects. These lay people provide information that enables her and other scientists to study bird life in ways that would otherwise be impossible. But, as Cooper notes in an interview with Yale Environment 360, the uses of citizen science go well beyond bird research. Bushmen in the Kalahari are using apps to document wildlife and natural resources that need to be protected. Environmental activists also are employing open-source technology to measure and monitor pollution, including the deployment of kites and balloons to document such events as the Deepwater Horizon oil spill. “A lot of the ways for us to move forward in certain fields require massive collaboration,” says Cooper. “And so we’re building all the infrastructure for these collaborations, all of the web tools — whatever we need to make that happen.”
