Offshore wind: a huge resource

Two wind energy items arrived in my inbox in close proximity recently. One was from the NZ Wind Energy Association (NZWEA) congratulating Meridian Energy on turning the first sod at Mill Creek wind farm in the Ohariu Valley north-west of Wellington. It’s a 60 megawatt farm of 26 turbines. The project will cost $169 million and is expected to be commissioned by mid-2014. It will increase NZ’s installed wind capacity from 623 megawatts to 683 megawatts.

NZWEA’s chief executive made appropriate remarks to accompany the announcement, reiterating the expectation that at least 20% of NZ’s electricity will be generated from wind by 2030 and noting the technology advances in harnessing wind which is now one of the lowest cost options for new generation in New Zealand.

It’s good to see the steady progress in the development of wind energy in NZ, although it seems to arouse little excitement in Government circles who reserve most of their interest for further  fossil fuel development. And a report in Saturday’s NZ Herald was a sobering reminder that the $7 billion invested in the oil and gas sector over the past five years puts it far ahead of any other local sector when it comes to investment in new productive capacity. NZ is hardly on the brink of transition from fossil fuels, hardly, it seems, even interested in the possibility while there’s money to be made from exploiting them.

Nick Smith: another fossil fuel fail

MP Nick Smith in a NZ Herald opinion piece this week uses the fracking debate to advance the cause of fossil fuel mining. He claims that fracking is important in the development of geothermal energy and then moves seamlessly to the notion that we are desperately in need of unconventional natural gas in order to save us from falling back on coal, which we will otherwise “inevitably burn”. In defending fracking he manages to nicely couple the fossil fuel natural gas with a renewable energy source, geothermal.

It’s not my purpose to argue here about fracking as a technology. What is dismaying about Smith’s article is the complacency with which he advances the cause of natural gas. Writing enthusiastically of the huge unconventional shale gas resources in the US, he claims gas emits one-third the greenhouse gas emissions of coal. I know its emissions are lower, but it was news to me that they were as low as that. I could find no source to substantiate that figure. A little over half is the best figure I have been able to locate, and there are big questions about methane leakage in the fracking process. However let that pass. The real issue is the unrestrained pursuit of unconventional fossil fuels, which as James Hansen has reminded us often enough will mean game over for the climate.

Roughan’s ready theory

John Roughan has a theory. The New Zealand Herald‘s columnist and leader writer waxes lyrical this week about the discovery of the Higgs boson bringing excitement back to science — science having been made dull by being “dominated by environmentalism” for too long. Others may wish to make fun of Roughan’s somewhat incoherent take on particle physics:

The glimpse of the ‘Higgs boson’, or something like it, allows minds to boggle on the existence of “dark matter” and the possibility there really is a dimension to the world that is beyond human sensory perception.

Who knows where that knowledge will lead? Next they will work out how to control the particle, then they will remove it to enable things – people – to travel at the speed necessary to explore the galaxy.

But bring it on, I say. Let’s get the Roughan-Higgs drive patented. That’s a new technology that could really drive the economic transformation of New Zealand. Truly ground-breaking stuff from a political columnist.

Roughan’s real theory, sadly, is much more mundane, and amounts to little more than an extended and ill-educated rant against environmentalism.

No dallying with denial

Will Hutton’s Observer column this week was forthright on the folly and danger of climate change scepticism. “Climate change is already hurting and, unchecked, will turn into a catastrophe.”  Against that statement he points to the intellectual bankruptcy of allowing ideological preference for reducing the role of government in society to somehow justify climate change scepticism. It’s not even as if capitalism is under threat of disappearance.  “Capitalism is not going away: the task is to reform it deploying a more agile, intelligent state.” But taxation and regulation will be part of that reform and the climate sceptics on the right need to come to their senses on that necessity.

Hutton’s was the sort of direct statement we should expect from informed journalists. He notes in passing that the media is often less interested in the evidence that it should be. “It likes a spat: the idiosyncratic brave climate change dissenter is pitched as the David against the Goliath of established opinion.”

The day after I’d read Hutton’s column the NZ Herald’s monthly magazine Element accompanied Monday’s edition of the paper and cheered up my morning. There was no dallying with denial here. Editor James Russell gave voice to the slight embarrassment many of us who worry about climate change probably feel in some company.

A sunnier outlook from the ground up

The NZ Herald business supplement recently carried a thoughtful feature by Peter Huck in which he described moves to combat climate change at lower levels than the floundering international negotiations. He begins with a report on Desertec Industrial Initiative, the German-led consortium which this year hopes to trial in Morocco a concentrated solar power plant as the harbinger of ambitious plans to provide very large quantities of solar and wind energy to North Africa and Europe.

Huck takes this as one of the many signals that the top-down approach to limiting carbon emissions through international deals is giving way to a ground-up attitude that stresses action.  Others include the EU’s introduction of a carbon tax on airlines that use its airports; Scotland’s investment in wave power; California’s embrace of renewable energy, clean fuels, a cap-and-trade programme to limit emissions, and other green policies; Ecuador’s efforts to preserve its forests by getting donors to pay it to keep oil in the ground; China’s approval last year of its 12th Five Year Plan, which aims to tackle energy consumption and CO2 emissions. Further down the chain Huck instances a growing urgency about reducing emissions which can mean corporate investment in renewable energy, municipal emphasis on public transport, or a family insulating their home.
