Support for greening the economy

It’s been interesting to see some NZ Herald articles bearing on the Green Party’s “100,000 green jobs” policy which I discussed a few days ago.

John Armstrong shared my view that the Green’s jobs policy deserved more than the “ritualistic slagging” offered by John Key and Steven Joyce.

National might still claim the Greens do not understand economics. The purpose of yesterday’s policy release was to demonstrate the Greens do understand – and are deadly serious about remedying the economy’s structural weaknesses, though not in a fashion National would favour.

Climate Change and Global Energy Security

Academics Marilyn Brown and Benjamin Sovacool, who have impressive credentials in the field of energy policy, are co-authors of the recently published Climate Change and Global Energy Security: Technology and Policy Options, a substantial and detailed study of a very wide range of technologies covering both the promise of those options and the obstacles to their effective employment.

I was deeply depressed by the time I got to page 64 of the book. That was where the tale of five challenges ended. The authors had enlarged the energy and climate change scope of the book somewhat to identify five challenges threatening the prosperity of future generations: electricity, transportation, forestry and agriculture, waste and water, climate change. They do it thoroughly, and it seemed well-nigh impossible that the growing population of the world could possibly cope with these problem areas. But the reader is counselled in the final paragraph of the chapter not to give up in despair, as the issues can be broken down into more manageable challenges to which technology and policy solutions are readily available.

Energy Strategy in Denial of Climate Change Reality

From a climate change perspective the New Zealand Energy Strategy 2011-2016 is hopelessly compromised by its determination to exploit all the oil and gas that can be found, including deep sea methane hydrates. Take a look at this extract, the second paragraph in the strategy document:

“Globally, there are two energy challenges: energy security and responding to climate change. Responding to these challenges is a major undertaking. Renewable sources of energy will help us meet these challenges, but we need to be realistic and acknowledge that there is no single answer. For the foreseeable future, fossil fuels will continue to be an important part of the global energy mix.” Continue reading “Energy Strategy in Denial of Climate Change Reality”

Revolution and realism required: UN report

I’ve been looking at the The World Economic and Social Survey 2011: The Great Green Technological Transformation which Gareth drew attention to in his recent post.  It’s a long document prepared by the UN Department of Economic and Social Affairs (DESA), not intended for casual consumption, and I haven’t read all 250 pages.  But the theme chosen for the year’s survey is fundamental for the challenge of climate change and it’s somewhat cheering just to see the title.  I thought it worth highlighting some of the content.

The survey is quite clear on the necessity for a green technological transformation. Our progress over the past two centuries has been at a cost to the natural environment which cannot continue.

“About half of the forests that covered the earth are gone, groundwater resources are being depleted and contaminated, enormous reductions in biodiversity have already taken place and, through increased burning of fossil fuels, the stability of the planet’s climate is being threatened by global warming.”

Merkel’s rush to renewables

I’ve become wary of politicians’ commitments to clean energy, having been disappointed by the rapidity with which the rhetoric of leaders like Obama or Rudd loses substance when the political going gets tough. But it was hard not to pay attention to a striking article in Yale Environment 360 this week in which Der Spiegel journalist Christian Schwägerl wrote of German Chancellor Angela Merkel’s new energy policy. In March, following the Fukushima disaster in Japan, she announced an accelerated phasing out of all 17 German nuclear reactors by 2022 at the latest.

“We want to end the use of nuclear energy and reach the age of renewable energy as fast as possible.”
