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 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

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
Thanks to Cool Green Science for this set of instructions for North American viewing of the sun’s near-disappearance:
Where will you be on August 21, 2017 when the solar eclipse passes through North America?
Here’s a guide to viewing opportunities, including Nature Conservancy preserves where you can catch the spectacle in beautiful surroundings.
Solar eclipses can be viewed from the earth’s surface about two to four times a year, but they aren’t viewable from all parts of the earth’s surface and the path of totality (the places on Earth from which viewers can see the total eclipse) is only about 50 miles wide. Eclipse 2017 stands out because the path of totality cuts a wide swath through the United States and all of North America will have views of a partial eclipse.

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
Thanks to EcoWatch for this note about the Google site that helps residents of major cities in the USA think more clearly about solar as an option:
Thanks to the Guardian for this series of videos:
Every day, the sun kickstarts mini power plants in about 942,000 homes around America. We are of course talking about solar energy – and in 2017, it’s never been cheaper to invest in it for your home. The Guardian looks at key tips for installing solar panels and why now is the time to switch

For every redemption story there seems to be at least one more redemption puzzle. Conundrums. This is one of those. We want to love the scheme for some of its nobler aspects, but then realize it is impossible to do so unconditionally. And finally, simply, impossible:

When we think of Normandy, apples and oysters come to mind. Calvados, too. We are happy those traditions endure but even happier to see the roads there as a hotbed of environmental innovation:
Thanks to Bloomberg for a surprising bit of good news about the prospects for solar energy going forward:
Emerging markets are leapfrogging the developed world thanks to cheap panels.
by Tom Randall
A transformation is happening in global energy markets that’s worth noting as 2016 comes to an end: Solar power, for the first time, is becoming the cheapest form of new electricity. Continue reading
We are constantly playing catch up with the terminology, let alone the science, of environmental efficiency in all its forms and considerations. Anthropocene delivers the daily goods, in the form of a summary of an environmentally-oriented scientific study, that we constantly find useful:
The title is either wishful thinking, or stating the obvious; we are not sure which. Thanks to our colleagues at Clean Technica for this:
Hawai’i Solar Power (In Depth)
by Carolyn Fortuna
Glorious blue skies and endless sunshine. Warm, balmy breezes. Isn’t that how you envision Hawai’i? Like the slogan, “Everything’s better in Hawaii,” right? Oops, one thing does dampen the impression of Hawai’i, though: its high cost of living, especially for energy. Continue reading
World electricity production going from black to green
In a significant first, the world now has the capacity to produce more power from renewables than from coal, according to the International Energy Agency.
In a time of troubling headlines, the more promising headlines can get lost, but they are there. At least with regard to renewable energy. Click the image above to read the summary of this book at Anthropocene or the image below to go to the source:
The rapid spread of renewable energy is a bright spot in the global energy transition towards a low carbon economy. Despite lower fossil fuel prices, renewable power expanded at its fastest-ever rate in 2015, thanks to supportive government policies and sharp cost reductions. Continue reading

Those of us who live near the Kochi Airport in Kerala, India feel pretty proud of our 100% solar-powered access to the outside world; but this story tells us to expect even more in the USA soon:
Thanks to the BBC for this story:
Silicon Valley’s biggest companies are investing in renewable energy in a serious way – a sign, perhaps, of rapid changes in the energy market.
By Chris Baraniuk 14 October 2016
Most people think of Apple as a company that makes phones, computers and smart watches – not an energy provider. But in August all of that changed when the firm was given permission to sell energy from a Californian solar farm that it acquired last year. Continue reading
Precisely two months ago we shared a great function by Google for investigating the potential for installing solar power in your neighborhood (mostly if you’re in the US). Last week, one of our most successful Instagram posts was of three shades of blue at Villa del Faro (see above), where photovoltaics are key. Panels are becoming less and less expensive, so hopefully the alternative energy will keep spreading! Continue reading
