19 Aug 2014: Wind Energy Prices at
All-Time Low, According to U.S. Report

The cost of wind power in the U.S. is at an all-time low of 2.5 cents per kilowatt hour, according to a new report

Major U.S. wind farms
from the U.S. Department of Energy, and utility companies are in some cases electing to use wind as an energy source over fossil fuels because of its low cost. Although wind power grew modestly in 2013 — installations were only 8 percent of those seen in the record year of 2012 — it now meets 4.5 percent of U.S. energy needs, producing enough electricity to power 16 million homes. The country ranks second only to China in installed wind capacity, the report says, and wind power accounts for 33 percent of all new U.S. electric capacity additions since 2007. That progress has been heavily dependent on federal, state, and local incentives, however, and wind power's growth could slow if those incentives expire. Its viability could also fall if natural gas becomes more affordable than wind, the report cautions.

The "Cash in Your Lawn" program in Los Angeles offers residents up to $6,000 ($3 per square foot) for replacing their lawns with drought-tolerant plants, rocks, and pebbles. Throughout the state, Governor Jerry Brown recently prohibited lawn watering more than two times per week and banned fines for brown lawns, which homeowner associations sometimes impose with the intent of improving a neighborhood's appearance. The drought, currently in its third year, threatens the water supply of California's 38 million residents. Agricultural regions have already seen severe water reductions, placing extra pressure on the state's groundwater reserves.

the International Energy Agency (IEA). In 2013, networked devices consumed around 616 terawatt hours (TWh) of electricity, with most of that used in standby mode. Roughly 400 TWh — equivalent to the combined annual electricity consumption of the United Kingdom and Norway — was wasted because of inefficient technology. The problem will worsen by 2020, the agency projects, with an estimated $120 billion wasted as devices such as refrigerators, washing machines, and thermostats become networked. Much of the problem boils down to inefficient “network standby,” or maintaining a network connection while in standby mode. Most network-enabled devices draw as much power in this mode as when fully active, the report notes. Using today's best technology could cut energy consumption by 65 percent, the IEA said.

Home Depot will require labeling by the fourth quarter of 2014, a company vice president said, and the retailer is testing to determine whether it's feasible to eliminate neonics altogether without compromising plant health. Another retailer, BJ's Wholesale Club, which has more than 200 East Coast locations, said it will ask suppliers to eliminate neonics by the end of the year, or label plants treated with them as requiring "caution around pollinators." An analysis of 800 peer-reviewed studies released this week by an international group of scientists found that neonics have been a key factor in bee declines.

24 Jun 2014: Concentrated Solar Power
Could Compete with Natural Gas, Study Says

Concentrated solar power (CSP) could meet a substantial percentage of current energy demand in some parts of the world, according to research

published in the journal Nature Climate Change. In the Mediterranean region, for example, the study shows that a grid-connected CSP network could provide 70 to 80 percent of current electricity demand, at no extra cost compared to natural gas-fired power plants. CSP could also feasibly meet energy demands in parts of southern Africa, according to researchers. CSP systems use mirrors or lenses to concentrate solar rays into a small area. The concentrated energy heats a liquid that produces steam to drive turbines, which means that the collected energy can be stored as heat and converted to electricity when needed — a major advantage over solar panels, which store energy much less efficiently.

12 Jun 2014: U.S. Breweries Cut Water
Use Amid Widespread Drought Conditions

Major breweries in the U.S. are cutting back on the amount of water they use to brew beer as drought threatens their water supplies, the Associated Press reports. MillerCoors, headquartered in Chicago, has reduced its water use by 9.2 percent since 2012, a company sustainability report said. Earlier this month St. Louis-based Anheuser-Busch, the largest U.S. brewer, reported that it has cut water use by 32 percent in the last five years. Employing strategies such as fueling boilers with wastewater, recycling water used to clean bottles and cans, and installing sensors to fine-tune irrigation in hop and barley fields, MillerCoors has cut water use to 3.48 barrels of water for each barrel of beer, the company says. The company is also giving $700,000 to landowners in the watershed of its Fort Worth brewery who make efforts to curb erosion and runoff by, for example, planting native grasses or rotating cattle grazing lands. Craft breweries typically use twice as much water as major breweries per barrel of beer, the AP notes, because they are smaller in scale and don't have access to the same technology.

more important as the state's long-term drought continues and the birds' wetland habitats dwindle. Using crowdsourced data, The Nature Conservancy (TNC) tracks the paths of migratory birds on their annual journey from Canada to South America to determine where and when the birds will need suitable wetland habitat for stop-overs in California's Central Valley. Then, in a sort of reverse auction, TNC asks farmers how much they would charge to temporarily flood their land to accommodate the birds, and pays farmers with the lowest bids to do so for a few weeks or months. The Nature Conservancy says the year-old program has been a success, enabling the organization to rent habitat for roughly 0.5 to 1.5 percent of what permanent protection costs. The program's budget is $1 million to $3 million annually. Forty farmers flooded roughly 10,000 acres last year, and sightings of key migratory bird species were 30 times above average, according to TNC.

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.

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.

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.

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."

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.

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.

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

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.

of corporations that have pledged measures to protect southeast Asian rainforests. 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.
