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

15 February 2016, Renew Economy, Nuclear commission findings spell more trouble for wind and solar in Australia. The South Australian Royal Commission into the nuclear fuel cycle has conceded that nuclear power is not a viable alternative for Australia, but has urged authorities to consider it anyway – in what could have serious implications for the roll out of renewable energy across the country. The commission delivered the results of its “tentative” findings on Monday, indicating that it supports the establishment of a nuclear waste facility in the state, the storing of spent nuclear fuel and the expansion of uranium mining. On the subject of nuclear generation, the commission admitted that it wasn’t viable in South Australia in the foreseeable future (2030) – even with a significant carbon price and a sharp reduction in the cost of capital. It conceded that Australia should only adopt “proven” new nuclear technologies such as “small modular reactors” and next generation “fast reactors” , but that these were some way off, and likely to be very costly. But commission chairman Kevin Scarce wants the nuclear generation dream to continue. He admitted that while there were real risks in nuclear generation – and there are “no guarantees on its safety” – he doesn’t “think the positive side of nuclear power is being presented.” Despite the findings of the commission on the high costs of nuclear, and its unsuitability to the South Australian market in particular, he wants nuclear energy to be part of the national consideration because of the challenges Australia faces in meeting its emissions abatement task. In effect, he and the nuclear proponents are betting that Australia will fall short in its climate targets; and given the record of the Coalition government on climate policy – including the repeal of the carbon price, the slashing of the renewable energy target, the attack on key institutions and slow progress on energy efficiency – that is a fair bet.

15 February 2016, Renew Economy, Tasmania energy prices to soar as supply crisis forces switch to diesel gen-sets. Energy consumers in Tasmania – already facing a trebling in wholesale electricity prices since the state lost its grid connection to the mainland, now face yet another trebling in prices as the government turns to highly expensive diesel gen-sets to protect its rapidly depleting hydro resources. The Tasmania government late Friday announced it would turn to diesel gen-sets to ensure the lights would not go out and was ordering at least 200MW of containerised diesel generators to be installed as hydro levels continue to fall and the repair to the Basslink cable to the mainland is further delayed. Tasmania enjoys among the cheapest costs of wholesale energy in the country when it relies only on hydro and wind energy. But prices doubled to around $90/MWh when it decided to import 40 per cent of its needs from Victoria in the face of the driest spring on record which forced hydro levels to fall to near record levels. That cost rose further to more than $110/MWh when the Basslink cable failed in December, and the government had to accelerate its plan to bring back its Tamar Gas power station into production. That has brought back 280MW of gas capacity into production, and Hydro Tasmania is now planning to add another 75MW of gas and up to 200MW of diesel power in “containerised diesel generation.” The cost of diesel generation is expected to be at least $300/MWh and may be more. As some diesel was switched on at the weekend, the average price of electricity jumped to more than $160/MWh on Friday and Saturday. This compares to prices of around $40/MWh last summer. The situation is highlighting the fact that wind energy and solar energy would have provided much cheaper power, and obviously much cleaner power, except the state authorities have passed up opportunities to accelerate the deployment of those technologies, despite having a large hydro resource to act as a battery.

9 February 2016, Renew Economy, Coalition restates wish to axe CEFC, then unveils its largest program. The Jekyll-and-Hyde nature of the Coalition’s clean energy policies were underlined again on Monday, with the Federal government trumpeting one of the biggest ever programs by the Clean Energy Finance Corporation, just hours after it repeated its wish to close the agency down. On Monday, Coalition MP Jane Ruston, appearing before a Senate Environment and Communications Legislation Committee hearing, had confirmed that it remained the Coalition’s intention to dismantle the CEFC, if it could get enough votes in the Senate. Greens Senator Scott Ludlam: Is it still government policy to abolish the CEFC? Ruston: …Yes. Ludlam: …Why? Ruston: …I think the government made it pretty clear when we were elected that we didn’t believe we should be in the job of being a bank. (Ruston apparently forgot that the Coalition has proposed the $5 billion northern Australia infrastructure fund, which is to operate on the same principles as the CEFC, just in a different area). Hours later, federal environment minister Greg Hunt trumpeted the launch of one of the green bank’s biggest investments yet, claiming credit for a $250 million energy efficiency program targeting community housing in Australian cities.
Hunt – in a media release sent while he was in Dubai, where he is attending the World Government Summit, and is thought to be a finalist in the “world’s best minister” award – said the CEFC-led program would drive the construction of market-leading energy efficient community housing project in 2016. He said this would contribute to the greening of Australia’s cities and built environment. It will provide as many as 1,000 new energy efficient dwellings Australia wide. Interestingly, Hunt said his department “had directed the CEFC to focus on cities and the built environment under its new Investment Mandate, which also included financing emerging and innovative renewable energy technologies as well as energy efficiency.” Read more here
