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.

World Could Warm 8 Degrees
Celsius If All Fossil Fuel Reserves Burned
As nations meet in Bonn, Germany this week to hash out how to achieve the 2-degree Celsius goal they set in Paris, new research is providing policymakers a glimpse of what would happen if the world does nothing to curb climate change.
What if nations chose instead to burn through all of their remaining fossil fuel reserves, equal to 5 trillion tons of CO2 emissions? According to the new study published in the journal Nature Climate Change
, the world would warm an average 8 degrees Celsius (14.4 degrees F), or up to 17 degrees Celsius (30 degrees F) in the Arctic. The research was conducted by a team of climate scientists at the University of Victoria and Simon Fraser University in British Columbia who wanted to understand the worst-case scenario. “Such climate changes, if realized, would have extremely profound impacts on ecosystems, human health, agriculture, economies, and other sectors,” the researchers write.
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."

Norwegian Company Building
The World’s Largest Floating Wind Farm
Scotland is about to get the world’s largest floating wind farm, with five 6-megawatt turbines bobbing 15 miles offshore in the North Sea.
The project—which is being developed by Statoil, a Norwegian energy company—marks a shift in offshore wind technology. Most ocean-based turbines to date have been rooted to the sea floor by concrete and steel foundations, similar to oil and gas rigs. But this design limits the projects to shallower waters. Statoil’s floating turbines, known at Hywind, consist of a steel cylinder filled with ballast water and stones, and are tethered to the sea floor by a series of cables. The company, which was granted a lease to build the wind farm this week
, will install the Scotland project in water more than 300 feet deep. The plan is for the wind farm to start generating electricity by the end of 2017.

Fumes from Farms Are
Top Source of Fine-Particle Pollution
Farms are the number one source of fine-particulate air pollution in the U.S., Europe, Russia, and China, according to new research published in the journal Geophysical Research Letters
Gases from fertilizers and livestock waste cling to emissions from cars, power plants, and factories to create solid particles less than 1/30th the width of human hair. Particles this size have been shown to penetrate deep into lungs, and cause an estimated 3.3 million deaths each year from illnesses like heart and pulmonary disease. Global climate action, however, could reduce this type of air pollution in the coming decades, says the new study, done by three Columbia University scientists. Cutbacks in energy consumption would mean that fumes from farms would have fewer emissions to which they could bond. This reduction in particulates would happen even if fertilizer use increases, the research says.

Despite Push for Renewables,
Fossil Fuels Likely to Dominate in 2040
World leaders pledged last year in Paris to cut CO2 emissions and limit global warming to 2 degrees Celsius. Despite these promises, U.S. analysts said Wednesday
that fossil fuels
— including coal — will still likely be the world’s primary source of energy in 2040. The findings are part of the U.S. Energy Information Administration’s annual World Energy Outlook report. Electricity from wind, solar, and hydropower will grow 2.9 percent annually, the report concluded, and by 2040, renewables, coal, and natural gas will each generate one-third of the world’s electricity. But diesel and gasoline will still power the majority of vehicles, with electric cars making up only 1 percent of the market, the report said. The report also found that carbon emissions from energy consumption in the developing world could grow 51 percent from 2012 to 2040
as countries like India and China modernize their economies, particularly by using coal.
Bringing Energy Upgrades
To the Nation’s Inner Cities
America’s low-income urban areas are filled with aging buildings that are notoriously energy-inefficient. It’s a problem that Donnel Baird sees as an opportunity. Baird is CEO and cofounder of BlocPower,
a startup that markets and finances energy-upgrade projects in financially underserved areas. Founded in 2013 with venture capital seed money, BlocPower bundles small energy-improvement projects together — from barber shops to churches —and sells them to potential investors. In an interview with Yale Environment 360
, Baird describes how BlocPower’s projects not only create jobs and reduce carbon emissions, but also raise awareness of global warming in inner-city communities. “It is not possible for the climate change movement to win anything significant without the participation of people of color,” says Baird.

Alberta Wildfire Could Unlock
Vast Reserves of CO2 from Permafrost
A massive wildfire raging in the heart of Canada’s tar sands region has forced 88,000 people from their homes
, scorched more than 1,600 buildings,
and caused several fossil fuel companies to reduce operations and shut down pipelines. The fire — fueled by above-average temperatures
and dry conditions linked to climate change — burned through more than 330 square miles of land in Alberta in just a few days. Now, scientists are warning the fire, and the many others like it that Canada has experienced in recent years, could unlock vast reserves of CO2 stored in the region’s underlying permafrost. Fire destroys the protective layer of vegetation that keeps permafrost frozen, and warm conditions spur microbial activity, generating CO2 and methane emissions. “This is carbon that the ecosystem has not seen for thousands of years and now it’s being released into the atmosphere,” Merritt Turetsky, an ecosystem ecologist at the University of Guelph in Ontario, told the New Scientist

Brazilian Officials Put a
Hold on Mega-Dam Project in the Amazon
A proposed 8,000-megawatt hydroelectric dam in the Amazon was put on hold this week by Brazil’s environmental agency out of concerns over its impact on a local indigenous tribe.
The São Luiz do Tapajós project — which would be Brazil’s second-largest dam and a cornerstone of government efforts to expand hydroelectric power — would require developers to flood an area the size of New York City and home to thousands of Munduruku people. The environmental agency, Ibama, said they were suspending the project’s licensing because of “the infeasibility of the project from the prospective of indigenous issues.” Brent Millikan, the Amazon program director for International Rivers, told Reuters
, "The areas that would have been flooded include sites of important religious and cultural significance. The local communities have a huge amount of knowledge about the resources where they are — if they were forced off the land and into cities they would become unskilled workers."

For James Hansen, the Science
Demands Activism on Climate
Climate scientist James Hansen has been a prominent figure in the global climate conversation for more than 40 years. His 1988 congressional testimony on climate change helped introduce the problem of rising greenhouse gas emissions to the American public,
and he has led study after study examining how our world will change as a result of global warming. Eight years ago, Hansen made the rare decision to begin engaging in climate activism—a move that has earned him both praise and criticism from the media and scientific community. In an interview with Yale Environment 360
last week, Hansen opened up about his unconventional career path and what he believes the world could look like a century from now. “I don't think that I have been alarmist — maybe alarming, but I don't think I'm an alarmist,” he said. “We have a society in which most people have become unable to understand or appreciate science, and partly that's a communication problem, which we need to try to alleviate.”

Half of World Heritage Sites Are
Threatened By Industrial Development
Since 1972, the United Nations has worked to protect 229 locations in 96 countries known for their “exceptional natural beauty” and “cultural significance.” These spots, known as World Heritage Sites,
The Great Barrier Reef
range from Mount Kilimanjaro in Tanzania to the Great Barrier Reef in Australia, China’s panda sanctuaries, and the Grand Canyon in the United States. A new survey by the World Wildlife Fund, however, has found half of these sites are under threat
from oil and gas development, mining, illegal logging, overfishing, or other industrial activities. Eleven million people live in or near these sites, the report says, and depend on them for their housing, food, water, jobs, or ecosystem services like flood protection and CO2 sequestration. “We are not going to develop a just and prosperous future, nor defeat poverty and improve health, in a weakened or destroyed natural environment,” the authors wrote.

As U.S. Oil Production Increases,
More Americans At Risk of Man-Made Quakes
As U.S.-based production of oil and gas has boomed over the last decade, millions of gallons of chemical-laden wastewater has been pumped and stored deep underground.
The risk of experiencing an earthquake in 2016.
It turns out, however, that this disposal method—popular for fracking waste—is causing a spike in the number of earthquakes across the country, according to a new set of maps from the U.S. Geological Survey
. Seven million Americans are now at risk from man-made quakes, particularly in Oklahoma, Kansas, Texas, Colorado, New Mexico and Arkansas. "My first thought was actually, ‘Holy crap, Oklahoma is redder than California,’" USGS geologist Susan Hough told The Washington Post
about seeing the maps for the first time. Unlike California, however, most of these states don’t have earthquake-ready structures, experts said, so communities are having to update building codes and purchase new insurance.

Could Bread Mold Help
Improve Rechargeable Batteries?
A type of bread mold might just be a key to creating better rechargeable batteries, scientists reported in the journal Current Biology
Researchers at the University of Dundee in Scotland discovered that the fungus Neurospora crassa
—known commonly as red bread mold—can transform manganese into a mineral composite with “excellent electrochemical properties” ideal for use in supercapacitors or lithium-ion batteries, said
Geoffrey Gadd, a microbiologist and lead author of the study. Those types of batteries are used to power everything from laptops to railways to solar energy systems. Scientists have long studied how to make batteries more powerful and sustainable and in an environmentally safer way, but this is the first time researchers have looked to mold as a possible solution.
Interview: How to Talk About
Young Conservatives for Energy Reform
Clean Energy With Conservatives
promotes a green energy agenda for Republicans. But the phrase “climate change” isn’t one you’ll find on the organization’s website.
Angel Garcia, the group’s national outreach coordinator, admits that pushing renewables in conservative circles is an uphill battle. “We have an ideology that seems like it’s ‘Drill, baby drill,’ with nothing else. So we have to fight against stereotypes that if you’re for clean energy, then you are not really a Republican.” In an interview with Yale Environment 360
, Garcia says the Republican Party has a vested interest in embracing clean energy since the issue resonates with young conservatives. “As demographics shift, this is becoming a more important issue. So it’s better to get in front of the issue now and embrace it.”

Obama Administration Pulls
Proposal to Drill in the Atlantic Ocean
The Obama administration withdrew its proposal to open up offshore oil and gas drilling in the Atlantic Ocean on Tuesday.
Offshore drilling rigs in the Gulf of Mexico.
The decision blocks drilling in the region until 2022 and comes after an outpouring of opposition
to the plan from environmental groups and mid-Atlantic coastal communities and businesses concerned about a possible spill like Deepwater Horizon in the Gulf of Mexico five years ago. “Public pressure forced the administration to reverse course on Atlantic drilling," May Boeve, executive director of the environmental group 350.org, said in a statement. “We will continue to make the case that any new drilling is a stain on the president’s climate legacy and incompatible with the goals he committed to at the climate talks in Paris.”

Five Years After Nuclear Disaster
Fukushima Remains Highly Contaminated
It has been five years since a powerful earthquake and resulting tsunami caused a meltdown at the Fukushima Dai-ichi Nuclear Power Plant in Japan.
Regulators visit the Fukushima site in 2014.
While a few towns closed after the disaster have reopened and some locals have returned, groundwater en route to the ocean, as well as nearby soils, remains highly contaminated with radioactive waste. Toxic water and soil that has been removed by the cleanup project’s 8,000 workers sits in a growing number of storage tanks on the property, several of which have leaked. Radiation levels are so high that robots sent to clean up the power plant itself are reportedly malfunctioning
, their circuits fried. "Fukushima Dai-ichi is a complicated cleanup site," said
Dale Klein, a former chairman of the U.S. Nuclear Regulatory Commission who now consults for the Tokyo Electric Power Company, which owns the plant. "This will be a several-decades process of cleanup.”

JP Morgan Will No Longer Invest
In New Coal Mines, Citing Climate Change
JP Morgan will no longer finance new coal mines or support new coal-fired power plants in “high income” countries, the banking giant said
in a policy statement on its website.
Coal mine in Jharia, India
Bank of America, Citigroup, Morgan Stanley and Wells Fargo have made similar pledges in recent months, all part of a larger divestment movement aimed at transitioning the world’s economies off fossil fuels. The anti-coal campaign has dealt a blow to an already struggling industry. The price of coal has dropped from $140 per ton in 2009 to $42 in 2016 as cheap, abundant natural gas and renewables have flooded the U.S. energy market. At the same time, support for climate action has grown, with the signing of an international climate agreement in Paris last December. “We believe the financial services sector has an important role to play as governments implement policies to combat climate change,” JPMorgan said

Oregon To Eliminate Coal
From Its State Energy Mix by 2030
Oregon has become the first U.S. state to eliminate the use of coal by legislative action. Lawmakers at the statehouse
Oregon's only remaining coal plant, in Boardman
voted Wednesday to eliminate coal from the state’s energy supply by 2030, and to provide half of all customers’ power with renewable sources by 2040. The legislation was hammered out between the state’s two largest utilities and environmental groups. Clean energy groups praised the legislation as one of the strongest pieces of pro-climate legislation in the U.S. in years. “In terms of the coal phase-out, this really is precedent setting,” said Jeff Deyette
, senior energy analyst at the Union of Concerned Scientists. There is only one coal plant currency operating in Oregon, and it is the state's largest single source of greenhouse gas emissions.

China's CO2 Emissions Fell in 2015 Due to Decline in Coal, Boost in Renewables
China's greenhouse gas emissions fell for the second year in a row in 2015, down 1 to 2 percent, according to a Greenpeace analysis
of new data released by China's National Bureau Statistics.
The Tangshanpeng Wind Farm in northern China.
China reduced its coal consumption 3.7 percent
in 2015, and installed 32.5 gigawatts (GW) of wind and 18.3 GW of solar power. The country's recent economic slowdown also helped reduce emissions. China is currently the world's largest emitter of CO2, responsible for nearly a quarter of global greenhouse gas emissions. At a UN climate conference in Paris in December, China pledged to peak its emissions by 2030 and boost renewables. "These statistics show that China is on track to far surpass its Paris climate targets," said Lauri Myllyvirta, a senior campaigner on coal for Greenpeace. "However, the trend is not moving as fast as it could."

California Natural Gas Leak Officially Largest Leak in U.S. History
The four-month natural gas leak that sickened hundreds of Los Angeles residents and forced the evacuations of 1,800 homes this winter has officially been deemed the largest methane leak in U.S. history, according to a study
in the journal Science
A natural gas facility in California's Aliso Canyon.
The California leak spewed a total 97,100 metric tons of methane into the atmosphere, up to 60 tons per hour—the equivalent of the annual greenhouse gas emissions of 572,000 cars. Methane is a greenhouse gas dramatically more potent than carbon dioxide over a short time span. The researchers collected the data during 13 different flights through the leaking gas plume. The measurements were so high the scientists said they double-checked their recording devices. "It became obvious that there wasn't anything wrong with the instruments," said
Stephen Conley, an atmospheric scientists at the University of California-Davis who led the study. "This was just a huge event."

Growing cannabis requires huge amounts of energy
“Marijuana is the most energy-intensive agricultural commodity that we produce,” said John Kagia

It is the first time the Supreme Court has granted a request to halt a regulation before its review by a federal appeals court. The 5-4 vote along ideological lines is a blow to the centerpiece of the Obama administration’s Clean Power Plan, its strategy to combat climate change. Those challenging the regulations claim the new rules, which are to be enforced by the Environmental Protection Agency, would have a devastating economic impact. The White House says it expects the regulations to survive legal challenges. The plan, designed to lower carbon emissions from U.S. power plants to 32 percent below 2005 levels by 2030, is the main tool for the U.S. to meet CO2 reduction targets pledged at the December climate talks in Paris.

West Virginia Flatter
After Decades of Mountaintop Removal
Decades of mountaintop coal mining have substantially altered the topography of central Appalachia, according to new
esearch by Duke University
Appalachian mountain and valley affected by mining
. Areas affected by mining are as much as 60 percent flatter than they were pre-mining. In mountaintop mining, bedrock is blasted away
to uncover coal seams below the surface. In addition to mountains reduced in height, the valleys are also affected; they can be substantially shallower after mining debris is deposited in them. The fill can be as deep as 200 meters, which can significantly alter water flow and contamination as well. "The depth of these impacts is changing the way the geology, water, and vegetation interact in fundamental ways that are likely to persist far longer than other forms of land use," said Emily Bernhardt, a professor of biology at Duke and co-author on the study.

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.

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.

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.”

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.

Massive Transformation to Clean
Energy in the U.S. is Possible, Study Says
A rapid and affordable transformation to wind and solar energy within 15 years is possible in the U.S., according to a new study by NOAA
Map showing U.S. wind energy potential
and University of Colorado Boulder researchers published in the journal Nature Climate Change
. This energy transformation could slash greenhouse emissions by as much as 78 percent below 1990 levels, the study said. One of the biggest issues with weather-related power generation is its inherent intermittent nature, leading utilities to rely on gas-fired generators and other reserves during cloudy or low-wind periods. The solution to this problem is to scale up renewable energy generation systems to match the scale of weather systems, the scientists said. The model partially depends on significant improvements to the nation’s outdated electrical grid, including the creation of new, high-voltage direct-current transmissions lines.
