8 March 2016, Energy Post, New data debunks clean energy claims Apple, Amazon, Google. Recent claims by owners of large data centers that a large part of their operations are powered by renewable energy have skeptics coming out of from under their solar panels. Now, there is hard data proving that skepticism is valid, writes energy consultant and author Jim Pierobon. He applauds the efforts of companies like Amazon, Apple and Google to strive for clean energy, but calls for more transparency on their actual practices. A recent report by Lux Research casts a large shadow on some data centers’ clean-energy claims. Scientists at Lux Research found the data centers frequently draw on far more coal-fired power with its much higher emissions than renewables. Companies such as Google, Amazon and Apple should be careful about the claims they make, lest they come across partly as PR stunts. Amazon’s claims are off-base in 23 of its data centers in Virginia. It is less than transparent about how it calculates its emissions “They aren’t doing as much as they claim about sourcing their electricity,” said Ory Zik, Lux Vice President of Analytics. Full-time Data centers need a lot of power to run 24/7. They cannot rely on the intermittent supplies that come from solar and wind energy systems. As a result, they must draw electricity from the regional power grid. Solar and wind systems they have deployed or are developing can help supply renewable power to their centers and to power grids. But they supply nowhere near enough electricity on their own to run operate data centers reliably full-time. Read More here

2 March 2016, Renew Economy, “Base load” power: a myth used to defend the fossil fuel industry. Last week, leading lights of the global fossil power industry gathered at a conference in Houston, Texas, for CERA, known in the sector as the “Davos of Energy”. They reportedly got the shock of their professional careers. They had invited the most senior executives from the biggest network owner (Chine State Grid Corp) in the biggest energy market in the world (China). The organisers fully expected their Chinese guest to endorse the “all of the above” marketing pitch, which is underpinning the “keep coal” campaign. No such luck. Despite prodding by leading oil industry commentator Daniel Yergin, the chairman of State Grid Liu Zhenya reportedly said the “fundamental solution was to accelerate clean energy, with the aim of replacing coal and oil.” Gasp number one. And then to more stunned silence, he and State Grid’s R&D chief Huang Han dismissed coal’s claim to be an indispensable source of “base load” generation. As the network operator builds out its clean power sources, they noted, coal-fired generators could only serve as “reserve power” to supplement renewables. “The only hurdle to overcome is ‘mindset’,” Liu said. “There’s no technical challenge at all.” The “base load” mindset, though, is a pretty big and powerful hurdle. Across the world it infests incumbent utilities, the coal and nuclear lobbies, conservative politicians, energy regulators, and many in mainstream media, who are clinging to the concept of “base load generation” as the last resort to try to ridicule wind, solar and other technologies. In Australia, which has more coal generation as a percentage of its energy supply than any other developed country, this perpetuation of this idea has reached fever pitch, particularly with the imminent exit of the large coal-fired power station in South Australia. But according to Tim Buckley, from the Institute of Energy Economics and Financial Analysis, the idea of “base load” generation as an essential part of the energy mix is becoming redundant, and turning into a myth dreamed up by the fossil fuel industry to protect its interests. “It’s as dangerous as the marketing term of “clean coal” and the idea that coal is “good for humanity”,” Buckley says.

26 February 2016, Climate News Network, US blocks India’s solar power plan. World trade regulations have been invoked by the US to challenge India’s ambitious programme to expand massively its renewable energy capacity and provide local jobs. India has been told that it cannot go ahead as planned with its ambitious plan for a huge expansion of its renewable energy sector, because it seeks to provide work for Indian people. The case against India was brought by the US. The ruling, by the World Trade Organisation (WTO), says India’s National Solar Mission − which would create local jobs, while bringing electricity to millions of people − must be changed because it includes a domestic content clause requiring part of the solar cells to be produced nationally. What a difference two months make. On 12 December last year, US President Barack Obama praised the Paris Agreement on tackling climate change, just hours after it was finally concluded. “We’ve shown what’s possible when the world stands as one,” he said, adding that the agreement “represents the best chance we have to save the one planet that we’ve got”. Clear-cut victory The WTO says that its dispute settlement panel “handed the US a clear-cut victory . . . when it found that local content requirements India imposed on private solar power producers in a massive solar project violated trade rules, although the two sides are still discussing a potential settlement to the dispute”. One official of India’s Ministry of New and Renewable Energy told India Climate Dialogue that the ruling might make the country’s solar plan more expensive, and would definitely hit domestic manufacturing and, consequently, the possibility of creating jobs in the sector.

25 February 2016, Renew Economy, Graph of the Day: The myth about energy subsidies. Ever hear the story about why renewable energy can’t compete without a subsidy? You hear it all the time from the fossil fuel industry. And the response from renewables? Take away fossil fuel subsidies, and they’d be glad to compete on level terms. This graph below, displayed today by David Hochschild, a commissioner with the California Energy Commission, at the Energy Productivity Summer Study in Sydney, illustrates why the fossil fuel and nuclear industries don’t want that to happen. Studies by the International Energy Agency point out that global subsidies for fossil fuels outstrip those for renewable energy nearly 10-fold. The International Monetary Fund said if climate and environmental costs were included, then the fossil fuel subsides increased another 10 times to nearly $5 trillion a year.
This graph, that Hochschild sourced from DBL Investors, shows the accumulated energy subsidies in the US under federal programs. Oil and gas dominate, followed by nuclear. Federal renewable energy subsidies, in the form of investment and tax credits, are a small fraction. “The fossil fuel industry hates to talk about that,” Hochschild told RenewEconomy in an interview after his presentation. “There is a myth around subsidies, but there is no such thing as an unsubsidised unit of energy.” Read More here
