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.

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
24 February 2016, Energy Post, What comes after solar PV? BIPV. The time of ugly solar panels is over. Make way for building-integrated photovoltaics. Fereidoon Sioshansi, president of Menlo Energy Economics and publisher of the newsletter EEnergy Informer, notes that BIPV not only look stunningly better, they also reduce costs. They can even lead to energy-producing buildings. Regardless of whether and how they are subsidized, solar photovoltaics (PVs) panels are gaining in popularity around the world, found on increasing number of roofs in sunny and even not so sunny countries. They continue to be installed in significant numbers even in places where they get little credit for any net generation into the network, as in Queensland, Australia. In such cases, customers adjust the size of the installations mostly for self-consumption. Traditionally, a customer with an existing roof would call a contractor to install them, paying out of pocket, or increasingly leasing them with little or no upfront investment. The result is generally an ugly, incongruous after thought, and an expensive one at that. Many roofs have protruding chimneys and other obstacles resulting in panels distributed in odd and unpleasant patterns. Other roofs are in wrong angles to the sun or shaded by neighbours‘ houses or trees, making them unsuitable for solar PVs. Today, an increasing number of architects and engineers are designing individual houses and entire subdivisions with solar panels in mind. The same goes for many commercial buildings, especially warehouses, parking garages, office buildings, shopping malls, airports, train stations – anything with large flat roofs. Including solar panels at the time the roof is being built reduces installation costs substantially, by some estimates as much as 20%. Read More here
23 February 2016, Climate Home, A flying fairy tale: Why aviation carbon cuts won’t take off. Ten days ago the airline industry stunned the world. After years of prevarication the world’s top airlines and leading manufacturers said they would take climate change seriously. The UN’s aviation body, ICAO for short, announced a carbon emissions standard that would apply to new aircraft from 2020, and to all new deliveries of in-production aircraft – current types, or minor variations on current types – as from 2028. Aircraft that don’t meet the standard will not be allowed to be produced after 2028. None of the operational aircraft currently in the fleet will be affected. The statement was widely acclaimed, notably by the US government. But will it really have any significant impact on reducing emissions? Our contention is it will not, riddled as it is with flaws. It will not be a “rigorous and challenging” standard as industry claimed, nor will it save the 650 megatonnes of CO2 emissions by 2040 that the White House proudly proclaimed. ICAO and states shaped the standard around parochial national manufacturer interests instead of the need to mitigate climate change. Aircraft designers will still face many challenges developing the next generation of airliners, but this standard will not be one of them. Beyond business as usual? New generation aircraft are generally some 10-15% more fuel efficient than those they replace. They need to be to sell. This translates to an average annual efficiency improvement of between 0.5% and 1.0%. Constant market pressures result in a continuously improving line when you plot the average fuel consumption of new aircraft types against their entry into commercial service date. Yet ICAO intends to regulate this ever improving trend with a flat (time independent) carbon standard. Even if the stringency is initially set at a level that will have an impact, its effect will quickly fade over time as market-driven improvements cut in. The maximum theoretical effect of the standard at maximum stringencies is just 1 gigatonne of CO2 between 2020-2040, while total CO2 emissions from aviation over this period will be in the order of some 31 Gtonnes, i.e. a potential saving of just 3%.
