Clearing the decks

A few quick links before I post on the government’s just announced energy strategy: cleaning out the tabs in my web browser…

  • Professor Graham Harris of the University of Tasmania addresses the issues I raised in my “ecological overdraft” post a few days ago, in Sleepwalking Into Danger – an article for ScienceAlert: “It is time to admit how little we know and face the risks of planetary degradation – this goes way beyond climate change. Biodiversity isn’t just birds, primates and whales; it is planetary function and resilience.”
  • The Royal Society For The Protection Of Birds is planning [Guardian, BBC] to allow the sea to reclaim 728 hectares of coastal land in the Essex marshes on Britain’s east coast to restore habitat for wildlife – and as a pragmatic adaptation to rising sea levels. Could we see the same sort of thing here?
  • The Andrill project – a sea floor drilling effort under the Ross Ice Shelf involving NZ and US scientists – is using nifty Apple computers, so Apple has posted an interesting perspective on the work being done. New drilling season starts soon.
  • Brian Fallow in the Herald takes a look at the cost of carbon in the new ETS and speculates about ongoing impacts on the government’s accounts.
  • Carbon emissions from shipping may be much higher than previously thought, according to The Independent (UK).
  • German solar power company Conergy is planning a 500 turbine windfarm near Broken Hill in New South Wales. Meanwhile, BusinessWeek (US) profiles entrepreneur John O’Donnell, who has bought into Aussie scientist David Mills solar thermal designs, and plans to build a lot of generation at costs competitive with coal. With Silicon Valley money, and soon.
  • The Dominion Post digs up some advice to government on dealing with “environmental refugees”. NZ will probably want to help small Pacific nations, but refugees from the Asian megadeltas might be another matter.

Biofuels to fly, and other stories

747Air New Zealand is carefully positioning itself as a climate-friendly airline with its latest announcement that it is to trial biofuels in a 747 flight from Auckland in the next couple of years. Working with Boeing, Air NZ will be part of the first commercial trial of biofuel, in a Rolls-Royce-powered jumbo in the next 18 months . The flight will only use biofuel in one engine, and will not carry customers. [Stuff, Herald, BBC, June HT blog on aviation biofuels].

NZ emissions trading scheme announced

NzetsDetails of the government’s planned emissions trading scheme (ETS) have been announced. Scoop has all the government speeches and press releases. I’m reading them at the moment, and will comment more later, but here are some highlights:

  • Foresters will receive the full value of carbon credits on new growth (from 1/1/2008) in post-1990 forests.
  • Agriculture will not be brought into the scheme until 2013.
  • NZ emissions units will be Kyoto-complaint and internationally tradeable (subject to some limits).
  • Some units will be allocated free, others auctioned.
  • Forestry will be first into the scheme in Jan 2008.
  • Transport’s next, in 2009, basically through fuel prices
  • Stationery energy (power generation) and heavy industry will enter in 2010, with no free allocation for electricity generators.
  • Farmers will get free allocation of units based on 90% of 2005 emissions, but details to be worked out

The government hopes that 90% of power generation will be from renewable sources by 2025. In transport, they want to cut per capita emissions in half by 2040, and encourage the wide use of electric vehicles. Goals for agriculture are more nebulous: to be the world leader in emissions reduction research, and to lead the world in agricultural emissions reductions. In forestry, they would like a net increase of 250,000ha in forest area by 2020.
The government has also released an update on our expected Kyoto deficit – up to 45.5 millions tonnes from 41.2 mT, mainly from increased dairy production. In the absence of any emissions reduction policy, the government projects this could rise to 65mT, but believes the ETS will cut the 2008-12 deficit to 25mT.
My first thought? Politically astute. By getting foresters on board with what amounts to a taxpayer subsidy, they get enough trees planted to offset a large chunk of the Kyoto liability, and buy time to bring agricultural emitters in to the scheme. More later.

Electric cars or coal-to-diesel?

TeslaThe carbon neutral flagship of New Zealand’s power sector, Meridian Energy, has announced that it’s planning to start trials on electric cars next year [Stuff, Herald] . CEO Keith Turner also announced a new service specialising in helping to design and build energy efficient homes, and a new environmentally friendly Wellington headquarters. Discussing the car trial, Turner said:

“The prize in making the move to electric vehicles comes when you recharge them with renewable electricity. Meridian will be able to demonstrate renewable, zero-emission, certified carbon neutral mobility.

How green is my skyline?

WindturbineReaders with functioning short term memories may recall that my local lines company, Mainpower, through its Local Generation subsidiary is planning to build a wind farm on Mt Cass, looking down over the Waipara Valley. The site (or a large chunk of it) can be seen from the comfy chairs on my veranda, testing my commitment to low carbon energy and landscape aesthetics. To help me (and others) come to terms with what this means, Mainpower’s main wind energy people, Andrew Hurley and Todd Mead, have launched a blog covering the planning and development process. It promises to give an interesting insight into the way wind farms are developed, and already demonstrates a refreshing openness about the process. Andrew’s commented here on wind issues, and has been up to Limestone Hills to talk climate blogs and wind, so I wish them luck with their new venture. Not sure about the turbines on the skyline though… 😉
