17 Jun 2016: California’s Roadside Trees
Provide $1 Billion in Municipal Services

The trees that line California’s streets and boulevards are worth an estimated $1 billion a year for the work they do in removing air pollution, storing CO2, cooling homes, and reducing rain runoff, among other municipal services,

Palm trees in Los Angeles, California.
according to a new analysis by the U.S. Forest Service and the University of California, Davis. The state’s 9.1 million street trees pull nearly 568,000 tons of carbon from the atmosphere annually, equal to taking 120,000 cars off the road, the study, published in the journal Urban Forestry & Urban Greening, found. The scientists say California has room to put another 16 million trees along its roads if it wants. "We've calculated for every $1 spent on planting or maintaining a street tree, that tree returns, on average, $5.82 in benefits," forester and lead author Greg McPherson said in a statement. "These trees are benefiting their communities 24 hours a day, 365 days a year."

15 Jun 2016: Clean Energy Could Cost Up To
59 Percent Less by 2025, Report Finds

The cost of solar energy could drop by as much as 59 percent by 2025, from 13 cents to 6 cents per kilowatt hour, according to a new report from the International Renewable Energy Agency.

Offshore wind could become 35 percent cheaper, and onshore wind 26 percent cheaper, by 2025. The cost of building renewable energy facilities is also likely to fall, by as much as 57 percent by the middle of next decade, the report found. “Historically, cost has been cited as one of the primary barriers to switching from fossil-based energy sources to renewable energy sources, but the narrative has now changed,” Adnan Z. Amin, director-general of IRENA, said in a statement. “To continue driving the energy transition, we must now shift policy focus to support areas that will result in even greater cost declines and thus maximize the tremendous economic opportunity at hand.”

10 Jun 2016: Researchers Find a Way to Turn
CO2 Into Rock at Iceland Power Plant

Scientists have discovered a new way to successfully capture carbon dioxide and transform it into rock deep underground. The experiment, published in this week’s Science,

Section of rock made from mixing CO2 and water.
was conducted at the Hellisheidi power plant in Iceland, the world’s largest geothermal facility. When the plant — which helps power Iceland’s capital, Revkjavik — pumps up volcanically heated water to turbines, gases like carbon dioxide and hydrogen sulfide often come up as well. A team of U.S. and European researchers, led by Columbia University's Lamont-Doherty Earth Observatory, captured the CO2, mixed it with the used volcanic water, and re-injected it into basalt rocks up to a half-mile underground. More than 95 percent of the mixture naturally solidified into carbonate minerals in less than two years. Previous estimates predicted that the process could take hundreds, if not thousands, of years.

03 Jun 2016: Increasing Hurricane Damage
Could Strain U.S. Emergency Relief Budget

As hurricane season in the U.S. officially got underway this week, federal financial experts warned that damage from tropical storms will “increase significantly in the coming decades” due to human-driven climate change, and that such a trend could threaten the national emergency relief budget.

New Jersey National Guard
“Over time, the costs associated with hurricane damage will increase more rapidly than the economy will grow,” the report from the U.S. Congressional Budget Office states. Right now, damage from hurricanes amounts to 0.16 percent of the U.S. GDP, or about $28 billion. As sea levels rise, intense storms become more frequent, and coastal development continues, the report estimates this share could reach .25 percent ($45 billion in today’s economy) by 2075. The federal agency suggested that one way to cut costs is “a coordinated effort to significantly reduce global emissions.”

02 Jun 2016: U.S. Officials Issue a
Sweeping Ban On Elephant Ivory Trade

The Obama administration finalized a rule this week banning the sale of nearly all elephant ivory within the United States.

The exceptions to the new rule include professionally appraised antiques at least a century old and items with fewer than 200 grams (7 ounces) of ivory. The rule does not apply to ivory from other species, such as walrus, whale, and mammoth, the U.S. Fish and Wildlife Service said in a statement. The new regulation is part of a recent global push to halt the trade of elephant ivory from Africa. Kenya burned 105 tons of confiscated ivory in April to raise awareness of the country’s growing poaching problem, and the country’s president, Uhuru Kenyatta, will seek a total ban on elephant products during an international wildlife trade meeting this fall.

26 May 2016: More Solar Energy Jobs Exist
In U.S. Than in Oil and Gas Sector

Solar energy now supports more jobs in the U.S. than either the oil and gas industry or coal mining, according to a new report from the International Renewable Energy Agency (IRENA).

Alex Snyder
Solar jobs grew at a rate 12 times faster than general U.S. job market growth. Worldwide, employment in green energy grew 5 percent in 2015, to 8.1 million jobs, IRENA reported. The 58 percent drop in oil prices since 2014 caused many fossil fuel companies to lay off workers — more than 350,000 people worldwide since the slump began. The IRENA report says clean energy jobs could triple to 24 million by 2030 if nations follow through on the climate pledges they made in Paris last year. “This increase is being driven by declining renewable energy technology costs and enabling policy frameworks,” said Adnan Amin, director-general of IRENA.

25 May 2016: Could This Straddling Bus Help
Solve China’s Air Pollution Problem?

With an estimated 20 million new drivers on the road each year, China has long struggled to control its CO2 emissions, air pollution, and traffic problems.

YouTube/Xinhua
But a Beijing-based transit company is planning to test a new straddling bus this summer that could provide some relief, according to Chinese news agency Xinhua. The bus, which can carry up to 1,400 passengers, hovers above the road, letting smaller vehicles pass underneath. Because it operates on existing roadways, the system is much cheaper to build than underground subways, while carrying the same number of people. The idea of a straddling bus has been around since 1969, but has remained a far-fetched concept until recent years. A model of the system, designed by Transit Explore Bus, was unveiled at the International High-Tech Expo in Beijing this month. The company plans to build and test an actual straddling bus in Changzhou this summer.

Interview: CO2 'Air Capture' Could
Be Key to Slowing Global Warming

For two decades, Klaus Lackner has pioneered efforts to combat climate change by pulling carbon dioxide from the atmosphere.

Now, after years of watching the global community fail to bring greenhouse gas emissions under control, Lackner — director of the Center for Negative Carbon Emissions at Arizona State University — is delivering a blunt message: The best hope to avoid major disruptions from global warming is to launch a massive program of CO2 "air capture" that will begin to reverse the buildup of billions of tons of carbon in our atmosphere. "We need to have the ability to walk this backwards," says Lackner. "I'm saying this is a war, and we need to use all the weapons at our disposal. You don't want to get into this fight with one hand tied behind your back."

20 May 2016: Obama Looking for Kids
As Science Advisors to the White House

White House advisors tend to be experts with decades of experience in specific fields, from foreign policy to education to energy.

Chuck Kennedy/White House
But President Barack Obama announced this week he’s looking for a much younger batch of consultants to advise the White House on science, technology, engineering, and math (STEM). The Kid Science Advisors outreach program will ask children which issues are most important to them and how to better engage students studying science to help guide White House policy and priorities. "The real reason we do this, as I’ve said before, is to teach our young people that it’s not just the winner of the Super Bowl or the NCAA tournament that deserves a celebration,” Obama said Thursday. “We want those who have invented the products and lifesaving medicines and are engineering our future to be celebrated as well."

19 May 2016: Brewing Company Creates
Edible Six-Pack Rings to Save Wildlife

Plastic six-pack rings have long been a nuisance to wildlife and ecosystems, fouling oceans and shorelines, and entangling and choking wildlife.

Now, a brewery in Florida has developed an edible version from the byproducts of making beer, including wheat and barely. If not eaten by marine creatures, the six-pack ring biodegrades. Saltwater Brewery 3-D printed 500 of the holders in April and plans to scale up production to package all of its 400,000 cans of beer per month in the edible rings. The material is just as strong as traditional plastics, the brewery says, but is more expensive. The price would drop, however, as more companies use the edible rings, the brewery said. “We want to influence the big guys,” Chris Goves, president of Saltwater Brewery, said in a video about the new project. “And hopefully inspire them to get on board.”

27 Apr 2016: Wooden Skypscrapers Grow in
Popularity in Effort to Reduce Emissions

Architects are increasingly abandoning traditional steel-and-cement skyscrapers in favor of wood-and-glue designs — a move that experts say could help drastically reduce CO2 emissions from the world’s building sector.

Acton Ostry Architects
Creating steel, iron, and non-metallic minerals — including concrete — is an energy-intensive process that accounts for more than 10 percent of global greenhouse gas emissions. In the 1990s, developers created a product known as cross-laminated timber — planks of wood glued together by a polyurethane adhesive — with the strength and durability of traditional building materials, and far fewer CO2 emissions. With concern for climate change mounting, wood-based skyscrapers have been popping up around the globe in recent years. The University of British Columbia, for example, approved an 18-story, wooden housing complex in 2015. “This revolution has happened rather quietly and happened rather slow,” Kris Spickler, a heavy timber specialist at Structurlam, told Popular Science. “But I think we’re in a year right now where we’re going to see it explode.”

21 Apr 2016: A Town Made Almost Entirely Out
Of Plastic Bottles is Being Built in Panama

Construction has begun on the world’s first town made almost entirely out of recycled plastic bottles. Located on Isla Colón in Panama, the village will consist of 120 houses and a lodge on 83 acres of tropical jungle.

The first two-bedroom home was built late last year, and is made from 10,000 plastic bottles pulled from Panama trashcans, roadsides, and beaches. The walls of the homes consist of steel cages filled with bottles and then encased in a concrete mix. They are flexible enough to withstand an earthquake, and insulating enough to keep the home up to 17 degrees F cooler than the jungle outside. Because there are so many recycled bottles on the island already, homes can be built quickly and cheaply, said Robert Bezeau, founder of the Plastic Bottle Village. “We are changing the world, without changing the Earth, one home at a time,” he says on the project’s website.

In addition to its own financing, the World Bank said it would work to mobilize $25 billion in commercial funding for clean energy over the next five years. “If we don’t act, climate change threatens to drive 100 million more people into poverty in the next 15 years,” John Roome, senior director for climate change at the World Bank Group, said in a statement. The new spending plan “will allow us to help developing countries more quickly, and in the areas where support is most needed, such as disaster preparedness, social protection, and coastal protection.”

17 Mar 2016: The World’s Economy Grew,
But Greenhouse Gas Emissions Didn't

Despite a 3.1 percent growth in global GDP in 2015, greenhouse gas emissions remained flat for the second year in a row, according to the International Energy Agency.

The decoupling of emissions from economic growth is “welcome news,” IEA executive director Fatih Birol said in the press statement. “Coming just a few months after the landmark COP21 agreement in Paris, this is yet another boost to the global fight against climate change.” The world’s nations released 32.1 billion metric tons of greenhouse gases last year, equal to—or perhaps even a slight downtick from—2014, the agency said. The stabilization is likely due to the booming renewable energy industry and global cutbacks on the use of coal, particularly in the U.S. and China, the two largest emitters of carbon dioxide. Chinese emissions, for example, declined 1.5 percent last year.

Over the last 15 years, UNICEF and the government of Malawi have rolled out nine million free mosquito nets to guard the health of pregnant mothers, their offspring, and refugees against the ravages of malaria. This has been a public health triumph. But the mosquito nets are also being used by villagers for netting fish in Lake Malawi, contributing to the rapid decline of the lake’s fish stocks, which dropped 93 percent between 1990 and 2010, according to the UN’s Food and Agriculture Organization. Overpopulation and deforestation also contribute to the problem, but misuse of mosquito netting is playing a significant role.

03 Feb 2016: China’s Wind Power Sector
Experienced Rapid Growth in 2015

China installed nearly half of all new global wind power generation last year and added as much new wind energy capacity in one year as the total capacity of the leading U.S. wind-producing states — Texas, Iowa, and California. Bloomberg New Energy Finance reports that China installed nearly 29 gigawatts of new wind-power capacity last year, surpassing the previous record of 21 gigawatts in 2014. China’s new wind energy capacity dwarfed the next-largest market, the United States, which added 8.6 gigawatts in 2015. Analysts said China’s wind sector grew rapidly because of declining manufacturing and installation costs, generous government feed-in tariffs, improving transmission capacity, and the government’s campaign to curb pollution from coal-fired power plants.

02 Feb 2016: General Electric Joins
The Move From CFL Bulbs to LEDs

General Electric, a leader in the lighting market, has announced that it will stop manufacturing compact fluorescent light (CFL) bulbs by the end of the year and

increasingly shift production to LED (light emitting diode) bulbs, which last longer, produce a better-quality light, and are rapidly declining in price. The move highlights a trend away from CFL bulbs, which several years ago were the go-to choice for energy-saving bulbs to replace energy-intensive incandescent light bulbs. “Now is the right time to transition from CFL to LED,” said GE lighting executive John Strainic. The price of an LED bulb has fallen from $30 to $5 in recent years and continues to decline. Retail giant Ikea abandoned CFL bulbs last year and now sells only LED lights, and other major retailers like Walmart are expected to follow suit — a move welcomed by environmental groups, which laud the large energy savings from LEDs.

27 Jan 2016: Rush to Electric Vehicles
Is Worsening Air Pollution in China

The push by the Chinese government and the country’s automakers to expand production of electric vehicles is actually worsening air pollution and carbon emissions because most of China’s electricity is still produced by coal-fired power plants, new studies show. Thanks to government incentives, production of electric and plug-in hybrid vehicles is expected to grow six-fold to two million cars and trucks by 2020. But studies by researchers at Tsinghua University show that electric vehicles charged in China with coal-fired power produce two to five times as many particulates and other pollutants as gasoline cars. The Tsinghua studies call into question the government policy of promoting deployment of electric vehicles while the vast majority of the country’s electricity still comes from coal. “International experience shows that cleaning up the air doesn’t need to rely on electric vehicles,” said one analyst. “Clean up the power plants.”

26 Jan 2016: Cost of Manufacturing Solar
Panels Is Projected to Continue Falling

The cost of manufacturing solar panels is dropping more quickly than previously predicted, putting solar energy on course to meet

20 percent of global energy demand by 2027, according to Oxford University mathematicians, who developed a new forecasting model. By contrast, the International Energy Agency’s predictions are far more conservative, stating that by 2050, solar panels will generate just 16 percent of global energy demand. The Oxford researchers' model predicts solar panel costs will continue to decrease 10 percent a year for the foreseeable future. Their model draws on historical data from 53 different technologies. The findings should help refute claims that solar PV cannot be ramped up quickly enough, said Oxford's Doyne Farmer, who co-wrote the paper. “We put ourselves in the past, pretended we didn’t know the future, and used a simple method to forecast the costs of the technologies,” he said.

In the summer of 2008, with gas prices hovering around $4 a gallon, Obama, then a candidate, set a goal of getting 1 million electric cars on the road by 2015, something he reiterated in his 2011 State of the Union address. Of the 250 million cars and trucks on U.S. roads, only 400,000 of them are electric. Sales fell six percent last year when compared to 2014, to about 115,000 vehicles, despite an increasing number offerings, often at sold at steep discounts. But cost remains an issue. Mostly due to the price of batteries, electric and hybrid cars often cost about $8,000 to $10,000 more than an equivalent gasoline-powered car.

07 Jan 2016: New Device Harvests Energy From
Walking and Exercising, Researchers Say

Researchers at MIT have developed a new method for harnessing energy generated by very small bending motions, which could be capable

of harvesting power from a broader range of natural human activities such as walking and exercising. Based on electrochemical principles — the slight bending of a sandwich of metal and polymer sheets, with materials similar to those in lithium ion batteries — the new technology can more effectively capture energy from human motions than previous devices. Those devices, which were based on frictional technology or the compression of crystalline materials, can capture energy from mechanical vibrations, but they are not as compatible with the pace of human movements, the researchers explain in the journal Nature Communications. When bent even a very small amount, the new layered composite produces a pressure difference that squeezes lithium ions through a polymer. The process produces alternating electrical current, the researchers say, which can be used directly to power devices such as cell phones and audio players.

The graphene technology is 10 times cheaper and more efficient than current methods of producing heavy water. "This is really the first membrane shown to distinguish between subatomic particles," said University of Manchester researcher Marcelo Lozada-Hidalgo.

23 Dec 2015: Congressional Tax Credits
Expected to Further Boost U.S. Renewables

The renewable energy sector in the United States is finishing 2015 on a high note as Congress has voted to approve significant extensions for tax credits for renewable energy, and the American Wind Energy Association (AWEA) has reported a surge in wind power installations. Ending uncertainty about the fate of tax credits for the wind and solar industries, Congress has voted to extend investment tax credits for solar power and production tax credits for wind energy through 2022 and 2020, respectively. Renewable energy companies and analysts praised the extensions, saying that, coupled with rapidly falling prices for wind and solar energy technologies, the tax credits virtually guarantee a boom in the production of renewables in the U.S. Earlier this week, the AWEA said U.S. wind energy production has reached a milestone, with 50,000 turbines providing a generating capacity of 70 gigawatts — enough to power 19 million homes.

14 Dec 2015: Accelerating Rock Weathering
Could Help Reduce Atmospheric CO2 Levels

Speeding up the naturally occurring process of weathering rocks to draw carbon dioxide out of the atmosphere could help to

stabilize the climate and avert ocean acidification caused by greenhouse gas emissions, according to research published in the journal Nature Climate Change. As rainwater and other environmental conditions naturally break down rocks on the earth's surface, carbon dioxide is drawn from the atmosphere. The process converts CO2 to bicarbonate, a mineral that chemically binds CO2 and is washed away through rivers to the oceans. By modeling the large-scale effects of weathering — which is driven largely by precipitation, vegetation, and soil microbes — the researchers found methods for accelerating this CO2-removal system. Such a strategy could significantly counteract anthropogenic fossil fuel emissions, they say, slowing ocean acidification and protecting delicate ocean ecosystems such as coral reefs.
