21 November 2016, Yale Climate Connections, Fuel Cells: Promising, but struggling to catch on. Fuel cells are efficient, generate clean electricity, and they run around the clock. So why aren’t we using them on a mass scale? Fuel cells have been the next best clean-energy thing for, well, a long time. The byproducts of that reaction are heat and water. The heat can be recycled into the fuel cell itself and/or used for external heating and cooling – generally referred to as combined heat and power. That makes stationary fuel cells – the kind used for electricity, as opposed to ones used in vehicles – extremely efficient and as clean an energy source as solar and wind.A technology with roots in the 1800s and modern-day use in every NASA-manned space flight from Apollo through the end of the space shuttle program, fuel cells just kind of look like a big box. Inside, they electrochemically combine hydrogen and the oxygen from ambient air to create electricity. But because the hydrogen source for most fuel cells comes from natural gas, they are generally not considered renewable, leaving them in an environmental limbo. Read More here

20 November 2016, New York Times, A Wrenching Choice for Alaska Towns in the Path of Climate Change. SHAKTOOLIK, Alaska — In the dream, a storm came and Betsy Bekoalok watched the river rise on one side of the village and the ocean on the other, the water swallowing up the brightly colored houses, the fishing boats and the four-wheelers, the school and the clinic. She dived into the floodwaters, frantically searching for her son. Bodies drifted past her in the half-darkness. When she finally found the boy, he, too, was lifeless. “I picked him up and brought him back from the ocean’s bottom,” Ms. Bekoalok remembered. The Inupiat people who for centuries have hunted and fished on Alaska’s western coast believe that some dreams are portents of things to come. But here in Shaktoolik, one need not be a prophet to predict flooding, especially during the fall storms. Laid out on a narrow spit of sand between the Tagoomenik River and the Bering Sea, the village of 250 or so people is facing an imminent threat from increased flooding and erosion, signs of a changing climate. With its proximity to the Arctic, Alaska is warming about twice as fast as the rest of the United States and the state is heading for the warmest year on record. The government has identified at least 31 Alaskan towns and cities at imminent risk of destruction, with Shaktoolik ranking among the top four. Some villages, climate change experts predict, will be uninhabitable by 2050, their residents joining a flow of climate refugees around the globe, in Bolivia, China, Niger and other countries.

19 November 2016, One Step off the Grid, Enova reaches major milestone, looks to expand and try peer to peer trading. Australia’s first community-based electricity retailer, Enova Energy, has reached major milestone of 1,000 customers, and is already looking to expand its geographic base and push into new areas such as peer to peer trading. Enova, based in Byron Bay in the northern rivers region of New South Wales, says it has reached its 1,000 customer level several months ahead of target, as it seeks to reach its break-even goal of 4,000 customers within the first two years of operation. CEO Steve Harris says the retailer has also attracted a higher number of business customers – 70 so far – which will help revenues, and possibly offset a small impact on margins from rising wholesale prices and high prices for large scale renewable energy certificates. Harris says there is clearly a groundswell of community interest in alternatives to the big oligopolies, and a fair deal on renewable energy. Nova, which describes itself as a “community owned renewable energy company”, pays 10c/kWh for solar feed in tariffs, more than 50 per cent above most retailers. “The higher feed in tariff is paying dividends for us. But it’s about community and it’s about environment. Households and businesses are showing they are quite happy to switch from their existing provider,” Harris told One Step Off The Grid in an interview. Harris says Enova is also benefiting from partnerships, such as a solar bulk buy program on the south coast of NSW, and another solar initiative in the ACT. Read More here
18 November 2016, ECO, UNFCCC – Fossil of the Day – The first Fossil of the Day award goes to…take a deep breath…Turkey, Russia, Australia, New Zealand, France, Japan and Indonesia for duplicity at the UN climate negotiations. While representatives from climate vulnerable countries, cities, businesses, and civil society organisations are fighting to keep dirty fossil fuels in the ground, as well as preventing the expansion of polluting airports (hat-tip to France), these countries still aim to increase their domestic fossil fuel extraction. By doing so, they are quite literally drilling under everyone’s efforts to keep global warming below the critical threshold of 1.5°C. These countries helped forge the Paris Agreement which is now in force, committing them to halt climate change, so they really need to get the left hand and the right hand talking to each other. Put your money where your mouth is, please! Read More here
