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.

U.S., Canada, and Mexico to
Set 50 Percent Renewable Power Goal by 2025
The United States, Canada, and Mexico will pledge on Wednesday to generate 50 percent of their electricity
from non-fossil fuel sources by 2025, according to U.S. officials. The three nations are expected to set the ambitious goal at a North American Leaders Summit in Ottawa. The commitment includes not just renewable sources of power such as energy and wind, but also hydropower, nuclear power, carbon capture and storage at coal-fired power plants, and gains in energy efficiency. Under that definition, the three nations now produce 37 percent of their electricity from renewable sources. Canada is leading the way in non-fossil fuel power generation, with 59 percent of its electricity coming from hydropower and 16 percent from nuclear plants. Continent-wide cooperation on clean energy issues has improved since the election last year of Justin Trudeau as Canada’s Prime Minister.

Abandoned Coal Mines Emit
As Much CO2 as a Small Power Plant
Thousands of abandoned coal mines dot the U.S. landscape, vestiges of old fossil fuel boomtowns and industrial hubs.
An abandoned coal mine in Ashland, Penn.
But despite no longer producing coal, these sites are still contributing to climate change by leaking carbon dioxide into the atmosphere, according to a recent study by scientists at West Virginia University
. The total amount of CO2 released annually by 140 abandoned sites in Pennsylvania is equal to that “of a small coal-fired power plant,” says the study, published in Environmental Earth Sciences
. CO2 is created when sulfuric acid generated during the mining process interacts with carbonate rocks. It is then carried to the surface
in runoff water. “Although considerable research has been conducted regarding the environmental legacy of abandoned mine lands, their role in carbon cycling is poorly [understood],” wrote the scientists. The findings “suggest that these waters may be important to carbon cycling on a regional scale.”

2015 Deadliest Year for
Environmentalists on Record, Finds Report
Last year was the deadliest year on record for environmentalists, according to a new report from Global Witness
, a nonprofit that tracks environmental and human rights abuses worldwide.
Indigenous people protest a dam in the Amazon.
One hundred and eighty-five people were killed trying to stop development of land, forests, and rivers in 16 countries in 2015 — equal to more than three people per week. The tally represents a 59 percent increase over 2014, and is double the number of journalists killed in the same period, according to the report. Environmentalists were most at risk in Brazil, the Philippines, and Columbia, which had 50, 33, and 26 killings last year, respectively. “This report sheds light on the acute vulnerability of indigenous people, whose weak land rights and geographic isolation make them particularly exposed to land grabbing for natural resource exploitation,” the Global Witness authors wrote. “In 2015, almost 40% of victims were indigenous.”

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.”

CO2 Crosses 400 ppm For Last
Time “Within Our Lifetimes,” Study Warns
Atmospheric concentrations of CO2 will stay permanently above 400 parts per million (ppm) this year due to El Nino—and will likely not drop below that number again “within our lifetimes,” according to a study published this week in the journal Nature
CO2 measurements from 1958 to today.
The milestone represents a symbolic threshold that scientists and environmentalists had long sought to avoid. Greenhouse gases have jumped 48 percent from the pre-industrial era, and 29 percent in just the past 60 years, from 315 ppm to 407 ppm today. CO2 concentrations tend to ebb and flow with the seasons, dipping as vegetation grows in summer and increasing during winter. But in the study published in Nature
, scientists at the U.K.’s Met Office and University of California, San Diego warned that because of the recent El Nino, CO2 concentrations wouldn’t fall below 400 ppm this year, or any year into the distant future.

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.

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.

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.”

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.”

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.

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
, director of industry analytics for New Frontier, which specializes in cannabis industry research. “That’s largely because of the very high energy costs associated with its cultivation and production indoors.” The report adds to mounting concerns over marijuana’s massive ecological footprint
. Authors of the report said simple steps like switching to outdoor or greenhouse cultivation, installing more efficient lighting and monitoring energy use could significantly reduce the industry’s energy footprint.
