Google to Power Itself Using
100 Percent Renewable Energy in 2017
Google announced that it has purchased enough solar and wind capacity, 2.6 gigawatts, to run entirely on renewable energy
The company, whose data centers and offices consume as much electricity as the city of San Francisco, will get most of its wind
energy from the U.S. Midwest, the Netherlands, Norway, and Sweden, and its solar from contracts in North Carolina and Chile. Google bought its first wind power in 2010 and is now the world’s largest corporate buyer of renewable energy. “The science tells us that tackling climate change is an urgent global priority,” said Urs Hölzle, Google’s senior vice president of technical infrastructure. “We believe the private sector, in partnership with policy leaders, must take bold steps and that we can do so in a way that leads to growth and opportunity.”

Hundreds of U.S. Businesses Call
For Continued International Climate Action
More than 360 U.S.-based businesses, including some of the world’s largest multinational corporations, sent a letter
Delegates at UN climate meetings in Morocco.
U.S. and world leaders this week asking them to continue to support the Paris climate agreement and speed up the transition from fossil fuels to renewable energy. "Failure to build a low-carbon economy puts American prosperity at risk,” the group said. “But the right action now will create jobs and boost U.S. competitiveness. We pledge to do our part, in our own operations and beyond.” The statement, presented at United Nations climate meetings
in Marrakesh, Morocco this week, was addressed to U.S. President-elect Donald Trump, U.S. President Barack Obama, Congress, and world leaders. Signatories include major conglomerates such as General Mills, Hewlett-Packard, Hilton, Nike, Kellogg, Unilever, Starbucks, and DuPont, as well as more than 50 other companies and investors with annual revenues exceeding $100 million.

For Third Year in a Row, Carbon
Emissions Flat as Global Economy Grows
Global carbon emissions from fossil fuels stayed flat in 2015 and are projected to increase by only 0.2 percent in 2016 — marking three years in a row that emissions have been decoupled from global economic growth, according to a new analysis
by scientists at the University of East Anglia and the Global Carbon Project
. The three-year slowdown is largely due to China’s declining coal usage, the study said, which helped the country reduce emissions 0.7 percent in 2015 and a projected 0.5 percent in 2016. But the scientists warned that emissions simply staying flat is not sufficient to combat climate change. “This third year of almost no growth in emissions is unprecedented at a time of strong economic growth… but it is not enough,” Corinne Le Quéré, a climate scientist at the University of East Anglia who led the data analysis, said in a statement. “Global emissions now need to decrease rapidly, not just stop growing.”

Scientists Attempt to
Create 3D Models of All Life on Earth
Scientists at the University of Massachusetts, Amherst have launched a new initiative to create 3D models
of all of the world’s living organisms.

Biologist Duncan Irschick invented a 30-camera array, the “Beastcam,” that captures high-resolution, full-color images of an animal’s body from all different angles. Using those photographs, Irschick and his colleagues have already created 3D models of sharks, scorpions, toads, and lizards. They plan to focus next on capturing frogs and sea turtles. The initiative, known as Digital Life
, is partnering with scientists, zoos, and non-profits to gain access to species, including those that are endangered or threatened, and providing 3D models at no cost via an open access website. “Digitally preserving the heritage of life on Earth is especially important given the rapid decline of many species,” said Irschick. “This technology can recreate organisms in a way that has never been done before.”

Diapers Made from Jellyfish?
Company Utilizes Super-Absorbent Qualities
Jellyfish populations around the world are on the rise, driven by rising ocean temperatures, increasing acidity, and overfishing.
A giant jellyfish.
But a start-up company in Israel has found a way to harness these booming jellyfish populations, using them to create biodegradable diapers and feminine hygiene products, The Guardian reported
. The company, Cine’al
, was created by University of Tel Aviv scientist Shachar Richter, who discovered that the flesh of jellyfish can absorb large quantities of liquids. By breaking down jellyfish bodies and adding antibacterial nanoparticles, Richter and his company have created a super-absorbent material they call “hydromash” that can be used in medical bandages, tampons, pads, and diapers. Americans currently throw away an estimated 40 million diapers every day, each of which can take years or decades to break down in landfill. The hydromash material takes only 30 days to biodegrade, the company says. Cine’al plans to have products ready for market in the next 18 months, according to The Guardian

Can We Turn CO2 into a Useable
Fuel? Scientists Say They Have Found a Way
Scientists at the Oak Ridge National Laboratory in Tennessee report that they have found a way to convert carbon dioxide into ethanol
, a usable fuel. The team used a spiky nanotechnology-based catalyst made out of carbon, copper, and nitrogen. When they applied voltage to the catalyst, CO2 dissolved in water turned into ethanol, with a yield of 63 percent. “We discovered somewhat by accident that this material works,” said Adam Rondinone, the Oak Ridge scientist that led the research. Because the materials are relatively cheap and the reaction can happen at room temperature, the researchers say the technique could be scaled up to store renewable energy as ethanol, for example, or to convert CO2 emissions into fuel. Finding new ways to use CO2 “in order to displace a fossil feedstock,” the scientists wrote in the study
, “is an appropriate intermediate step towards a carbon-free future.”

Is There Too Much Emphasis
Being Placed on Carbon Capture Technology?
The world is placing too much credence on being able to combat climate change by pulling carbon dioxide from the atmosphere, a process known as “air capture
,” according to an article in the journal Science
this week. “Negative-emission technologies are not an insurance policy, but rather an unjust and high-stakes gamble,” wrote the article’s authors
, Kevin Anderson, a climate scientist at the University of Manchester in the U.K, and Glen Peters, a scientist at CICERO, a climate research organization in Norway. “There is a real risk they will be unable to deliver on the scale of their promise,” and assuming otherwise is “a moral hazard par excellence,” they wrote. Carbon capture technologies are a key component of the Paris climate agreement, with many of the modeling scenarios assuming the technology will be operating on a large scale later this century, reported Climate Central

Scientists Creating “Super Grass”
To Cut Methane Emissions from Cows
Danish scientists are developing a grass that will cut down how often cows burp and pass gas — reducing the amount of methane, a potent greenhouse gas,
Dairy cows in Europe.
they release into the atmosphere. Collaborating with international seed company DLF, the scientists are working to create a “super grass” that is easier for cows to digest, thereby reducing the amount of gas that builds up in their stomachs, several media outlets reported
. Global emissions of methane — which is roughly 30 times more potent than carbon dioxide over a 100-year period — have been on the rise since the 1980s. Livestock, specifically cows, are thought to release an estimated 90 million tons of methane into the atmosphere annually. The new, nearly $2 million research collaboration between the University of Aarhus in Denmark and DLF hopes to develop the new grass by 2024, at the latest.

built on the premises, according to a draft directive from the European Union. The new rule, to be published by the end of the year, is meant to help nations curb transportation-related greenhouse gas emissions, cut air pollution, and reach climate targets. Norway and the Netherlands, for example, both plan to phase out diesel engine vehicles by 2025, according to The Guardian
. “This kind of market stimulus is not just positive, it is mandatory if we want to see a massive rollout of electric vehicles in the near future,” said Guillaume Berthier, head of electric car sales for automaker Renault. “The question of how you recharge your car when you live in an apartment within a city is a very important one.”

Scotland to Generate Some of
World’s First Kite-Driven Power in 2017
The United Kingdom will begin harnessing energy from kites flying 450 meters above ground as early as next year. Developed by UK-based Kite Power Solutions
A kite-powered wind energy generator.
the system is composed of two 40-meter wide kites that rise and fall in tandem, spooling a tether line to turn a turbine. A test site was previously built in Essex
, and a 500-kilowatt system will be built near Stranraer, Scotland on the West Freugh air force station. Because the kites are lighter than wind turbines, they can more easily be built offshore and reach higher altitude winds, which are faster and more consistent. The technology, which companies hope could revolutionize global renewable energy strategies, is also being tested
in Switzerland and Italy, among other countries.
Public Art or Renewable Energy?
New Designs Aim to Produce Both
When the topic of energy infrastructure comes up, works of art don’t usually come to mind. But hundreds of such hybrid creations — part renewable power generators,

part large-scale art installations — now exist, at least on paper, as the result of a sustainable design competition known as the Land Art Generator Initiative
. Multi-disciplinary teams across the world have taken up the challenge to come up with buildable designs that produce renewable energy and “add value to public space, inspire, and educate.” In a photo essay, Yale Environment 360
highlights eight submissions to this year’s biennial competition, including the three winners announced this week. All designed for the waters off the Santa Monica Pier in Southern California, the systems range from a ring-shaped farm floating offshore to sail-like structures that harvest drinking water from fog.

Could California’s Gridlock
Generate Electricity for the Grid?
California is testing whether its heavy traffic can produce not just emissions and air pollution, but electricity.
Traffic on Interstate 80 near Berkeley, Calif.
The state’s Energy Commission says it will spend $2 million to examine the potential of using piezoelectric crystals embedded under asphalt as a way to send the energy created by moving cars to the grid. The crystals generate energy when compressed by the weight of moving cars, but tests of the technology at larger scales have failed or been canceled in Tokyo, Italy, and Israel, according to the Associated Press
. California, therefore, “needs to figure out whether it can produce high returns without costing too much,” the AP writes. If successful, the technology could help the state reach its goal to generate 50 percent of its electricity from renewable sources by 2030. California is expected to hit a 25 percent renewables target by the end of this year.

World’s Coffee Supply
Threatened by Climate Change, Report Says
A new report says that climate change could significantly reduce the amount of suitable land on which to grow coffee
and lead to an increase in outbreaks of diseases that threaten the crop. The report
— released by the Australian non-profit, the Climate Institute — warns that under current emissions scenarios, coffee-growing regions could see a 50 percent drop in the acreage fit to raise coffee plants, which need a precise combination of temperature and precipitation to thrive. Rising temperatures are also likely to lead to an increase in diseases like coffee rust and pests like the coffee berry borer, the report said. Major coffee-producing countries in the “bean belt” — including Colombia, Mexico, Brazil, Ethiopia, and Vietnam — have already become less hospitable because of shifts in weather patterns, the report said. “It’s a severe threat,” said an executive at U.S.-based Peet’s Coffee.

Scientists Find New Way
To Convert Carbon Dioxide into Energy
Scientists have discovered a way to convert greenhouse gas emissions into a fuel
in a single step using a light-driven bacterium, according to new research published in the Proceedings of the National Academy of Sciences
. A team of U.S. scientists, led by biochemists at Utah State University, used a modified version of the phototrophic bacterium Rhodopseudomonas palustris
as a catalyst to break apart carbon dioxide and turn it into hydrogen and methane, the latter of which can be burned to generate electricity. "It's a baby step, but it's also a big step," said Utah State biochemist Lance Seefeldt
, a co-author of the study. "Imagine the far-reaching benefits of large-scale capture of environmentally damaging byproducts from burning fossils fuels and converting them to alternative fuels using light, which is abundant and clean."
For China’s Massive Data Centers,
A Push to Cut Energy and Water Use
China’s 1.37 billion people, many of them fully connected to the Internet, use an enormous amount of energy as they email, search the Web, or stream video.

Indeed, the Chinese government estimates that the country’s data centers alone consume more electricity than all of Hungary and Greece combined. But as Chinese technology and internet businesses look to burnish their environmental credentials and lower costs of operation, many are working to run their massive computing facilities more sustainably. Globally, tech giants such as Microsoft, Google, and Amazon are making rapid progress in this field, as they boost energy efficiency at data centers and seek to completely power their operations using renewable energy.

July Electric Car Sales in China
Rose by 188 Percent Over Last Year
Chinese consumers bought 34,000 new electric cars in July, a 188 percent jump over the same period last year, according to CleanTechnica
, an energy and technology news organization. The monthly total puts China on track to sell 400,000 electrical vehicles in 2016, accounting for 1.5 percent of the total auto sales market — larger than annual EV sales in Europe, or the U.S., Canada, and Mexico combined. By the end of the year, China is projected to have 700,000 electric cars on its streets; the vast majority of EV sales, 96 percent, are for Chinese-made cars, including from manufacturers BYD Auto, Zhidou, and SAIC Motor. Tesla accounts for just 2 percent of EV sales in the country, and Porsche just 1 percent.

Roughly 2 Percent of U.S. Homes
At Risk from Sea Level Rise, Report Finds
Almost 1.9 million homes in the U.S. — roughly 2 percent of the nation’s housing stock, worth $882 billion — could be underwater by 2100 with six feet of sea level rise,
Boston homes at risk of flooding.
according to a new report by Zillow
, an online real estate database. One in eight Florida homes, representing $413 billion in property value, could flood by the end of the century. In Hawaii, one in 10 homes are at risk and in New Jersey, one in 13. The new analysis is based on climate projections and mapping from the National Oceanic and Atmospheric Administration, as well as Zillow’s database of 100 million U.S. properties. It found coastal cities, such as Miami and Honolulu, are particularly vulnerable to sea level rise. More than 1 in 6 Boston homes could be underwater by 2100. These estimates don’t include commercial buildings or government properties.

Ukraine is looking for investors for a 1-gigawatt solar farm in the 1,000-square-mile exclusion zone, where radiation levels remain too high for farming or forestry, reported Bloomberg
. The project would cost $1.1 billion and transform Chernobyl into one of world’s largest solar installations. Government officials say that two U.S. investment firms and four Canadian energy companies have expressed interest in the project. The European Bank for Reconstruction & Development is also considering financing the solar farm. “The Chernobyl site has really good potential for renewable energy,” Ukraine’s environment minister Ostap Semerak said
. “We already have high-voltage transmission lines that were previously used for the nuclear stations, the land is very cheap, and we have many people trained to work at power plants.”

Global Economy Has Reduced
Its Energy Intensity By One-Third Since 1990
The global economy is becoming less energy intensive
, using fewer fossil fuels to power productivity and economic growth, according to new data from the U.S. Department of Energy.
Rooftop solar panels
Global energy intensity — a measure of energy consumption per unit of gross domestic product (GDP) — has decreased nearly one-third since 1990, the agency said. The U.S., for example, burned 5,900 British thermal units per dollar of GDP
in 2015, compared to 6,600 BTUs in 2010. China burned 7,200 BTUs per dollar in 2015 versus 8,300 BTUs in 2010. The Department of Energy says the decrease is the result of the growth in low-carbon energy sources, such as wind and solar, and improved energy efficiency. “This is excellent news,” Penn State University climatologist Michael Mann told Climate Central
. “The dramatic drop we are seeing in global energy intensity is a direct indication that energy efficiency measures are having a very direct impact on global carbon emissions.”

Ford is Developing Car Parts
Made Out of Captured Carbon Dioxide
Ford Motor Company is developing car parts made out of captured CO2 to help reduce the environmental footprint of their vehicles. The automaker is working with Novomer, a Massachusetts-based chemistry company, to convert CO2 emissions from sources like power plants into foams and plastics for use in everything from headrests, seat cushions, and instrument panels, according to The Washington Post
. Most foams and plastics in Ford cars today are made out of petroleum, the Post reported, meaning that not only do the cars use fossil fuels as they drive, but also in their construction. So far, Novomer has been able to replace about half of the petroleum in foam with CO2-based materials — at least in the lab. It could be years before the technology finds its way into commercially available Ford vehicles. The company claims to be the first automaker
developing CO2-based car parts.

Tax Credits Double Projections
Of Solar Growth in One U.S. Market
A new market report
estimates that U.S. rooftop solar in the Mid-Atlantic region will likely increase exponentially over the next five years thanks to extended federal tax credits. The Business Energy Investment Tax Credit
that Congress unexpectedly renewed last December gives homeowners and developers 30 percent back on solar panel installations and other renewable energy investments through 2019. The program could help solar installation growth in the Mid-Atlantic reach over 9,000 megawatts by 2021, doubling previous projections, according to the report, which was conducted by market research firm CreditSights. Such a jump would alleviate the need for U.S. power companies to subsidize electric needs with nuclear, natural gas, or coal during peak energy consumption periods. “If rooftop solar grows more than 30 percent, there’s no reason we couldn’t see electricity demand growth go negative in the coming years,” Greg Jones, a New York-based analyst with CreditSights, told Bloomberg News

Paris Bans All Pre-1997
Cars During Weekdays to Fight Pollution
Starting this month, Paris is banning all cars built before 1997 from driving within city limits Monday through Friday in an effort to lower air pollution levels.
Commuter traffic in Paris.
Paris has been struggling with smog for years and its pollution levels have briefly topped those in Beijing. Similar to Mexico City and New Delhi
, Paris banned even- and odd-numbered license plates on alternating days to fight smog earlier this year. It has also championed cleaner transit options, such as bike- and electric car-sharing programs. Not everyone is enthused, however: The French consumer group 40 Million Drivers said the ban could impact up to 500,000 vehicle owners in and around Paris, particularly low-income families. "When you have an old car in France, it's because you don't have the money to buy a new one," Pierre Chasseray, the executive director of 40 Million Drivers, told NPR
. "Public transport is a solution, but it's not the solution for everybody."

U.S. Solar Energy Market
Experiencing an Unprecedented Boom
Thanks to a renewal of federal tax credits and a continuing steep drop in the price of photovoltaic panels, U.S. solar energy production is surging to record highs.
New market reports show that the U.S. solar industry is expected to install 14.5 gigawatts of solar power in 2016, nearly double the record 7.5 gigawatts installed last year. (Less than 1 gigawatt of solar power was installed in 2010.) Revenues from solar installations increased 21 percent from 2014 to 2015, surpassing $22 billion. In terms of megawatts of electricity produced, new solar installations are expected in 2016 to surpass all other new sources, including natural gas-fired power plants. The extension of a 30-percent federal tax credit and a sharp drop in prices — the wholesale price of solar panels has fallen from $4 per watt in 2008 to $0.65 per watt today — are contributing to the boom. U.S.-based Solar World is building a giant solar panel factory in Buffalo, New York that is expected to employ 3,500 people.

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."

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
Rooftop solar panels in Hannover, Germany.
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.”

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.

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.”

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.

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).
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.

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.
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.
