12 July 2016, Renew Economy, ACT could make windfall gains from bold 100% renewables target Who is the smartest energy minister in the country? At the moment, you would have to say it was the ACT’s Simon Corbell, the mastermind behind the territory’s bold 100 per cent renewable energy target, and who is poised to deliver massive savings to consumers in the nation’s capital. Indeed, if current wholesale electricity prices continue as they are across Australia, the ACT will not just have zero emissions electricity by 2020, it may also be getting most of it for free. This extraordinary situation arises out of the nature of the contracts that the ACT government has written with the project developers who have won its unique reverse auction tenders. The ACT has locked in fixed prices at between $77/MWh and $92/MWh for a total of 400MW of wind energy capacity so far. If the wholesale price is below those contracts, the ACT government pays the difference. If it is above, the ACT electricity utility ActewAGL receives the excess. In the past two months, wholesale prices across Australia have gone through the roof, mostly because of soaring gas prices (at record levels in most states), and supply constraints. Some of these rises have already been passed on to consumers. The first of the ACT commissioned wind farms, the 19MW Coonooer Bridge project in Victoria, opened earlier this year and gets a guaranteed $81.50/MWh from the ACT. But prices in Victoria have regularly jumped above $100/MWh in the past two months. Read More here

7 April 2016, Energy Post, Wind and solar’s Achilles heel: what the methane meltdown at Porter Ranch means for the energy transition. Utitlity-scale wind and solar power are typically backed up on-site by gas peakers, or backed up indirectly by gas-fired power plants. These gas plants lead to significant greenhouse gas emissions in the form of methane. So at what point does a renewable-plus-gas combination become worse for the climate than coal-fired power? Mike Conley and Tim Maloney, long-time members of the Thorium Energy Alliance, have calculated what they call a “Worth-It Treshold” that gives the answer. And they conclude as things stand, natural gas isn’t a bridge to a sustainable future.“We need about 3,000 feet of altitude, we need flat land, we need 300 days of sunlight, and we need to be near a gas pipe. Because for all of these big utility-scale solar plants – whether it’s wind or solar – everybody is looking at gas as the supplementary fuel. The plants that we’re building, the wind plants and the solar plants, are gas plants.” 1– Robert F. Kennedy, Jr. Environmental activist, Member of the board of Bright Source, developers of the Ivanpah Solar Station, Nevada, a 392 MW (peak) concentrated solar plant. Part One Natural Gas – the polite term for methane The methane leak in the Los Angeles suburb of Porter Ranch is America’s worst environmental disaster since the 2010 Deepwater Horizon oil spill in the Gulf of Mexico. But even more troubling is the larger issue of “fugitive” methane, and what it means for our growing reliance on wind and solar energy. Burning methane for energy produces about half the CO2 of coal, which is a good thing. But fugitive methane – the gas that leaks before it can be burned – is a powerful greenhouse gas, with 84X the Global Warming Potential (GWP) of CO2. The big idea behind wind and solar farms is to fight global warming by reducing greenhouse gases. But since most of a farm’s power is actually generated by gas, the rationale for a massive build-out of utility-scale wind and solar hinges on the issue of fugitive methane. That rationale just had a major meltdown at Porter Ranch. Read More here
22 March 2016, Reuters, Australia announces A$1 billion clean energy fund, in break with past. Australian Prime Minister Malcolm Turnbull on Wednesday said the country would establish a A$1 billion ($761.60 million) clean-energy innovation fund, in a major departure from his predecessor’s much maligned approach to combating climate change. Conservative former Prime Minister Tony Abbott was criticized by environmental groups for lagging behind other advanced economies when he announced cuts to Australia’s greenhouse gas emissions last year. Abbott, a climate change skeptic who was ousted in a party coup by Turnbull in September, also faced criticism for his strong support for the coal industry and for scrapping an ambitious carbon tax and emissions trading plan in 2014. Turnbull said the new fund would focus on investing in high-tech clean energy technologies. “What that is going to do is every year invest A$100 million in the smartest, most cutting edge Australian clean-energy technologies and businesses to ensure that we … play our part in cracking the very hard problems, the challenging technical difficulties that we face in terms of reducing emissions,” he told reporters. Abbott pledged that the world’s largest exporter of coal and iron ore would cut emissions by 26-28 percent of 2005 levels by 2030, a target he submitted as part of negotiations on a global climate deal in Paris last year. Abbott also sought and failed to scrap the country’s Clean Energy Finance Corporation and the Australian Renewable Energy Agency, which Turnbull said on Wednesday would be retained. Australia is one of the largest carbon emitters on a per capita basis due to its reliance on coal-fired power plants, and critics say it has done little to match ambitious targets set by the United States and Europe.

11 March 2016, YALE Climate Connections, Aspen 3rd City in U.S. to Go 100% Renewable. Aspen, Colorado . . . home to a winter playland of skiing, snowshoeing, trekking, and now, 100 percent clean energy. Aspen started transitioning away from fossil fuels in the 1980s with two hydroelectric dams. Then last summer, the city purchased enough wind energy to meet the last 25 percent of its energy needs – the equivalent of taking 4,000 cars off the road for a year. Aspen joined Burlington, Vermont and Greensburg, Kansas in relying solely on clean energy. David Hornbacher, Aspen’s director of utilities and environmental initiatives, says although every community is unique, each one can put together a portfolio of clean power. HORNBACHER: “We’re the third municipal electric utility in the nation to achieve this and each did it by a different route. So let’s let each of these organizations inspire others to find their path to one-hundred percent renewable.” Now Aspen’s renewable energy portfolio includes wind, water, and solar power. By using the forces of nature to power the community, Aspen hopes to inspire other communities to take action. Read More here
