New energy and energy efficiency strategies announced

 Wp-Content Uploads 2007 08 WindturbineRenewables are the key to New Zealand’s future energy needs, according to the government’s new energy strategy, published today [HTML, PDF]. No new thermal generation should be built over the next ten years, the government is going tell the power generation and distribution state owned enterprises. New generation capacity is expected to come from an expansion of wind and geothermal generation. The energy strategy is complemented by the new energy efficiency and conservation strategy (EECS) [web, PDF], designed to help homes, businesses and transport reduce their energy use.
Announcing the energy strategy, David Parker said (Scoop audio):

The government does not believe it is in the interests of the country for the SOEs to build any more base-load thermal generation. The government will be writing to the SOE generators to make it clear that it expects them to follow this guidance. We are also considering additional measures to ensure our message is loud and clear, for all generators, not just SOEs. Competitive neutrality between the private sector and SOEs is important.

In the transport sector, the government wants to encourage biofuels, greater fuel efficiency, and low-carbon vehicles. It foresees as much as 60% of the light vehicle fleet being electric powered by 2050. The strategy also call for the development of a domestic sea freight strategy, looking to build an integrated rail/sea freight system to reduce reliance on roads. [“Key points” press release]

In her speech launching the EECS, Jeanette Fitzsimmons said:

“This is an action plan to make a real difference to Kiwi families so that they can live in warmer, drier, healthier homes that cost less to heat; for business to become more competitive; and to save money and emissions in the transport sector. The strategy is set to deliver annual non-transport energy savings of 30 PetaJoules per year by 2025. That’s the same as the electricity used by 30 cities the size of Nelson in 2006 or 18 months of coal-fired production from Huntly, at 2006 levels. In transport, cumulative savings by 2025 will be around 4.8 billion litres of fuel.”

All good stuff, but someone should tell her officials that a PetaJoule is a bit more than 1015 Joules – as defined at the back of the strategy document. That should be 10 to the power of 15, a thousand trillion joules, or 1,000,000,000,000,000 joules. Either that, or Nelson is the most energy efficient town in the known universe. Mike Ward clearly doesn’t need to be mayor…

Reaction so far seems mainly positive. More from me when I’ve had a chance to read the strategy documents in detail.

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].

The whey forward?

New Zealand’s first E10 biofuel – a blend of petrol with 10% ethanol – went on sale in three Gull petrol stations around Auckland last Wednesday, and the PM poured the first drop [Herald]. The ethanol comes from Fonterra, mainly from their Edgecumbe dairy factory in the Bay of Plenty, which can produce 30,000 litres a day from processed whey. Gull Force 10, as the fuel is branded, ran into its first bit of trouble when the AA warned motorists to check that their cars were compatible with the fuel before filling up [Stuff]. This swiftly became “cars could break down and blow up

Fuel from willows

Interesting interview with Jim Watson, former President of the Royal Society of NZ on Kathryn Ryan’s Nine to Noon programme this morning (podcast here, but only for a week). Watson, the founder scientist of Genesis Research & Development discusses the new Biojoule project being established at Taupo. A species of willow (not the cricket bat kind) will be grown and harvested to produce ethanol as a biofuel, and lignin, a biological chemical alternative to hydrocarbons from fossil fuel as a feedstock for plastics. Home grown technology in every sense of the word.

Do android farmers dream of electric tractors?

Here’s a way to reduce agricultural emissions: the electric tractor. Global Public Media make the case for the electric tractor as a means to eliminate fossil fuel use (and helpfully explain why farms can’t be self-sufficient in biofuels):

This week we took a (petroleum-powered) scenic drive through the redwoods to the Mendocino coast to visit Stephen Heckeroth and demo his “Solar Electric Tractor.
