Energy advice ignores the climate crisis

An extraordinary op-ed headline caught my eye in the NZ Herald this morning. “Oil and gas reserves can be part of low carbon future.” Professor Basil Sharp, director of the University of Auckland Business School’s Energy Centre and Frank Duffield, an Honorary Fellow at the Centre, argue that continuing exploration for oil and gas reserves is entirely compatible with a low carbon future for New Zealand.

Their starting point is that developing a low-carbon economy will take longer and cost more than many people realise and in the meantime we must ensure that we have continued access to the energy we need.  This they claim is a reality which is ignored in debates about mineral resources and could mean that we miss out on significant development opportunities which could actually enhance our environmental credentials.

Rebutting myths and misconceptions about wind energy

I’ve been listening to a lively keynote address given to the NZ Wind Energy Conference earlier this month. The speaker was Lawrence Jones from Alstom Grid. He’s an expert on integrating variable renewable energy sources into global power grids. It was a heartening talk for anyone concerned to see renewable energy, wind in particular in this case, advance rapidly to take the primary position it must do if we are to have any hope of staving off the worst effects of global warming. All the more heartening because it was based on a major research project conducted by Alstom Grid on behalf of the US Department of Energy exploring the challenges and best practices for grid integration in many countries of the world.

I’ll offer a brief overview of the talk here, but I recommend it as worth listening to in full. There’s an audio of it on the Wind Energy Association website, and the accompanying slides are on this pdf file. Continue reading “Rebutting myths and misconceptions about wind energy”

Unstoppable waves of innovation in the Waikato?

A pleasant surprise this morning to see across the front page of the Waikato Times the headline “Waikato’s plan to harvest sunlight”.  The article reports that lines company WEL Networks has been evaluating photovoltaic cells and is now investigating the feasibility of solar power production in the Waikato region.

Commercial viability is the determining factor. It’s the dramatic fall in the cost of photovoltaic cells which has caused WEL Network’s investigation. CEO Julian Elder said that the low price of the cells, compared with where they were a few months ago, made solar power stations affordable in New Zealand. He said that in the space of a few months the return on investment had gone from about half a century to under 10 years.

We are looking at the whole range, from 1-2 kilowatt units on a house, up to the thousands of kilowatts for a large-scale pilot,” Dr Elder said.

He said it was not a case of if they built such power stations but a matter of when.

Europe’s renewable power continues to increase

Some encouraging renewable energy news in a recent press release from the European Wind Energy Association.  Their analysis of the 27 National Renewable Energy Action Plans shows that the EU-27 will meet 20.7 % of its 2020 energy consumption from renewables, exceeding the 20% target.

The National Action Plans show that one third (34%) of EU electricity demand will be supplied from renewables by 2020. Wind energy will be the largest contributor, generating 14% of Europe’s total electricity demand in 2020 (494 TWh from 213 GW installed capacity). Other renewables are expected to contribute as follows: 10.5% from hydro, 6.6% from biomass, 2.4% from solar photovoltaic, 0.5% from CSP, 0.3% from geothermal and 0.1% from ocean.

Minister wants all options open

The Minister for Economic Development Steven Joyce had a curious op-ed in the Herald earlier this week. It was aimed at those pesky people who obstruct progress when government tries to remove roadblocks in the way of business development.

And that’s when the problems start to arrive. The people who say “we want jobs” but then in the next breath say “but you can’t do that … you can’t build that there … you can’t expand that … you can’t explore for that there … you can’t live here … you can’t invest in property here – you just can’t do that!”

And very quickly we start limiting our options.

It was all safely general. No specific examples were provided. However, I recognise myself  amongst the people he is complaining about, and am happy to provide some of the detail missing from his article. Continue reading “Minister wants all options open”
