Three scientists at the University of Manchester have shared their findings in a journal whose title we had not been aware of, but are glad to know is looking out for us all:
Science of the Total Environment is an international journal for publication of original research on the total environment, which includes the atmosphere, hydrosphere, biosphere, lithosphere, and anthroposphere.
Since most readers of our pages likely use this type of oven on a daily basis, it seems worthy of a moment to read their findings as abstracted below:

130 M microwaves in the EU consume 9.4 TWh of electricity annually.
First LCA for microwaves to estimate the environmental effects of EU regulation
Standby Regulation will reduce impacts by 4–9% by 2020; WEEE Directive by ~ 0.3%.
Decarbonisation of electricity will reduce most impacts by 6–24% by 2020.
Eco-design regulation for microwaves should be developed to reduce resource use.
More than 130 million microwaves are affected by European Union (EU) legislation which is aimed at reducing the consumption of electricity in the standby mode (‘Standby Regulation’) and at more sustainable management of end-of-life electrical and electronic waste (‘WEEE Directive’).

Thanks to the Guardian for giving Bill McKibben the space to put the New York City decision in perspective:
Over the years, the capital of the fight against climate change has been Kyoto, or Paris – that’s where the symbolic political agreements to try and curb the earth’s greenhouse gas emissions have been negotiated and signed. But now, New York City vaulted to leadership in the battle.
On Wednesday, its leaders, at a press conference in a neighborhood damaged over five years ago by Hurricane Sandy, announced that the city was divesting its massive pension fund from fossil fuels, and added for good measure that they were suing the five biggest oil companies for damages. Our planet’s most important city was now at war with its richest industry. And overnight, the battle to save the planet shifted from largely political to largely financial. Continue reading
MIT Climate CoLab allows the public to vote for promising crowdsourced ideas on how to tackle climate change.

Norway’s public policy that puts environmentalism front and center stands in stark contrast to the obvious deconstruction of protections in this country.
Sales of electric and hybrid cars in Norway outpaced those running on fossil fuels last year, cementing the country’s position as a global leader in the push to restrict vehicle emissions.
Norway, a major oil exporter, would seem an unlikely champion of newer, cleaner-running vehicles. But the country offers generous incentives that make electric cars cheaper to buy, and provides additional benefits once the vehicles are on the road.
Countries around the world have ramped up their promotion of hybrid and electric cars. As China tries to improve air quality and dominate new vehicle technology, the government there wants one in five cars sold to run on alternative fuels by 2025. France and Britain plan to end the sale of gasoline- and diesel-powered cars by 2040.
Norway is ahead of the rest of the world. Continue reading
Biomethane is an age-old concept in much of what is frequently called the “developing world”, so it’s difficult to overstate the irony of “1st world” adoption. That said, it’s heartening to read of more projects aimed at maximizing poo’s full potential.
A long winding road climbs into a gathering dusk, coming to an abrupt dead end in front of a house. Here, a solitary flickering flame casts out a warm glow, illuminating the nearby ridge line of the Malvern Hills.
Below the light sits a mysterious green contraption resembling a cross between a giant washing machine and a weather station. This is the UK’s first dog poo-powered street lamp, and it is generating light in more ways than one.
The idea seems simple enough: dog walkers deposit the product of a hearty walk into a hatch and turn a handle. The contents are then broken down by microorganisms in the anaerobic digester, producing methane to fuel the light, and fertiliser…
…Humans have used animal dung as fuel since the neolithic period, and have known how to get flammable gas from decaying organic matter since the 17th century. Small-scale anaerobic digesters are commonplace in many developing countries, while larger plants producing heat and electricity from animal manure and human sewage have long been used in the west.
Yet the energy in most excrement still goes to waste. Continue reading
Thanks to Fred Pearce over at Yale Environment360 for this puzzler:
A loophole in carbon-accounting rules is spurring a boom in burning wood pellets in European power plants. The result has been a surge in logging, particularly in the U.S. South, and new doubts about whether Europe can meet its commitments under the Paris accord. Continue reading
Battery technology is the thing. It seems to be a holy grail that environmentalists and technologists can agree on for helping us, humans who want a habitable planet for generations to come, mitigate climate change. And occasionally it is at the core of short term fixes. Once the dust has settled on 2017, and we are looking back on stories that were on the positive side of long term impact on the planet, this story will probably get more attention. For now it seems like a footnote at the end of the year to note that this Tesla scheme actually seemed to work:
Last spring, Elon Musk made a daring bet. He claimed he could build and install the world’s largest grid storage battery in South Australia within 100 days of the date a contract was signed or the system would be free. The contract was signed on September 29. Installation was completed by the third week of November. On December 2, the giant 129 MWh system was activated. Continue reading
The Estonian government is so eager to take on big problems that many ambitious techies leave the private sector to join it.Illustration by Eiko Ojala
This is about people with an idea pursuing it with confidence in the ability of government to achieve something that its people want. Not everyone, everywhere, would want this to be sure. But it is a vote in favor of pursuing the common good together. It is worth the read, on a cold winter’s night (or wherever you may be) for a glimpse of the future for those in small, flexible places:
Its government is virtual, borderless, blockchained, and secure. Has this tiny post-Soviet nation found the way of the future?
Up the Estonian coast, a five-lane highway bends with the path of the sea, then breaks inland, leaving cars to follow a thin road toward the houses at the water’s edge. There is a gated community here, but it is not the usual kind. The gate is low—a picket fence—as if to prevent the dunes from riding up into the street. The entrance is blocked by a railroad-crossing arm, not so much to keep out strangers as to make sure they come with intent. Beyond the gate, there is a schoolhouse, and a few homes line a narrow drive. From Tallinn, Estonia’s capital, you arrive dazed: trees trace the highway, and the cars go fast, as if to get in front of something that no one can see. Continue reading

Some things we lose slowly, which seems better than losing them quicker; other things we gain too slowly:
Tuesday should have been a day of unmitigated joy for America’s oil and gas executives. The new G.O.P. tax bill treats their companies with great tenderness, reducing even further their federal tax burden.

And the bill gave them something else they’ve sought for decades: permission to go a-drilling in the Arctic National Wildlife Refuge. But, around four in the afternoon, something utterly unexpected began to happen. A news release went out from Governor Andrew Cuomo’s office, saying that New York was going to divest its vast pension-fund investments in fossil fuels. The state, Cuomo said, would be “ceasing all new investments in entities with significant fossil-fuel-related activities,” and he would set up a committee with Thomas DiNapoli, the state comptroller, to figure out how to “decarbonize” the existing portfolio.

Lisa Friedman appears twice on today’s landing page of the newspaper she works for, once as co-host on a video, below, about Alaska; and again as host of an equally important story in the form of an interview, also captured on this video titled Jerry Brown on How to Fix Global Warming.
How can policymakers fight climate change in the face of political headwinds? Gov. Jerry Brown of California addresses that question at ClimateTECH, a conference from The New York Times, in a conversation with Thomas L. Friedman.

Thanks to the Guardian for this update on the current state of the art of wind power, and it is good to see Britain in the lead:
Wind isn’t just mysterious, destructive and exhilarating – capturing just 2% of it would solve the planet’s energy needs at a stroke. And as the windiest country in Europe, Britain is at the forefront of this green revolution Continue reading

The often maligned Calvin Coolidge quote the “Business of America is Business” takes on a positive note when we consider that in the current political climate many corporations are stepping up where the federal administration falls short.
After the November elections, many of us in the climate and energy fields were rightfully fearful. What would happen to international agreements to cut greenhouse gases? What would happen to funding for climate research? What would happen to the green energy revolution?
In most instances, Trump is worse than we could have imagined. But in one special area, the president may not matter. That is in the growth of corporate purchasing of renewable energy. It turns out there are factors that even he cannot stop that make choosing renewable energy an easy decision for many companies.
New evidence about the unstoppable renewable energy wave recently came out in a report that was released by Apex Clean Energy and the GreenBiz Group. These groups surveyed corporations to determine their future plans on renewable energy installation and adoption. They wanted to know whether these plans had changed in the past few years and what motivated their decisions to implement renewable energy strategies. The outcome of this survey is available here for people who want to read the entire document.
The groups surveyed 153 major corporations (both public and private), whose combined revenue was in excess of $250 million. Among these companies, 84% are “actively pursuing or considering purchasing renewable energy over the next 5-10 years.” Surprisingly, they found that 43% of the corporations intend to be more aggressive in their pursuit of renewable energy in the next two years. 87% of those actively pursuing renewable energy purchases stated that the election had no impact on their decision.
In fact, 11% were more inclined to purchase renewable energy. Continue reading

Farming seaweed, using the power of the sun and the vast resources of the oceans, is a topic we expect to be featuring more of in these pages, and whether considering it as food or fuel we know the folks at the salt will be one of our primary sources delivering the goods:
The push for renewable energy in the U.S. often focuses on well-established sources of electricity: solar, wind and hydropower. Off the coast of California, a team of researchers is working on what they hope will become an energy source of the future — macroalgae, otherwise known as kelp.
The Pacific Coast is known for its vast kelp forests. It’s one of the fastest-growing plants on Earth, and farming it requires no fertilizer, fresh water, pesticides, or arable land. “It can grow 2 to 3 feet per day,” says Diane Kim, one of the scientists running the kelp research project at the University of Southern California.

Chile’s near catastrophe with hydroelectric energy, averted in part thanks to the efforts of friends in the Patagonia Sin Represas campaign, made us wonder whether Chile’s path to a greener future would be straight and narrow. Thanks to the New York Times and Ernesto Londoño we think we have strong evidence helping us with the answer:
CERRO PABELLÓN, Chile — It looks and functions much like an oil drilling rig. As it happens, several of the men in thick blue overalls and white helmets who operate the hulking machine once made a living pumping crude.

With the ability to power roughly 165,000 homes, the new plant is yet another step in Chile’s clean energy transformation. This nation’s rapidly expanding clean energy grid, which includes vast solar fields and wind farms, is one of the most ambitious in a region that is decisively moving beyond fossil fuels.

Latin America already has the world’s cleanest electricity, having long relied on dams to generate a large share of its energy needs, according to the World Bank.
But even beyond those big hydropower projects, investment in renewable energy in Latin America has increased 11-fold since 2004, nearly double the global rate, according to a 2016 report by the International Renewable Energy Agency, an intergovernmental organization. Chile, Mexico and Brazil are now among the top 10 renewable energy markets in the world.
So as Latin America embraces greener energy sources, government officials and industry executives in the region have expressed a sense of confusion, even bewilderment, with the Trump administration’s decision to withdraw from the climate changecommitments contained in the Paris Agreement, declare an end to the “war on coal” and take aim at American environmental regulations.

Thanks to the Conversation for highlighting the potential of this inspiring technology.
Bren Smith, an ex-industrial trawler man, operates a farm in Long Island Sound, near New Haven, Connecticut. Fish are not the focus of his new enterprise, but rather kelp and high-value shellfish. The seaweed and mussels grow on floating ropes, from which hang baskets filled with scallops and oysters. The technology allows for the production of about 40 tonnes of kelp and a million bivalves per hectare per year. Continue reading

We appreciate California’s heroic measures to take responsibility and show leadership where it can on climate change:
Over the past decade, California has passed a sweeping set of climate laws to test a contentious theory: that it’s possible to cut greenhouse gas emissions far beyond what any other state has done and still enjoy robust economic growth.
Now that theory faces its biggest test yet. Last August, the State Legislature set a goal of slashing emissions more than 40 percent below today’s levels by 2030, a far deeper cut than President Barack Obama proposed for the entire United States and deeper than most other countries have contemplated.
So how will California pull this off? Continue reading
