The Climate Show #23: Durban and the return of the electric car

[youtube]tbmbC8dXOiU[/youtube]

Grab some holly, deck your halls, heat up some mince pies, and then settle down to the last Climate Show of 2011. We look at the outcome of the Durban conference, discuss heavy rain in New Zealand and record-breaking weather extremes in the USA, and ponder the implications of news of more methane erupting from the seabed off Siberia. Glenn interviews Chris Paine, director of EV documentary Revenge of the Electric Car, and we round off the show with some optimistic news on possible energy solutions.

Hidden treasure is fools gold

The Institute of Professional Engineers New Zealand (IPENZ) has launched a new document, Realising Our Hidden Treasure: Responsible Mineral and Petroleum Extraction. The title says it all, and it’s the same message as the government has been feeding us for the last three years.

First the treasure. The document sets it out in dollar terms. I’ll mention only the fossil fuels here. They estimate the potential value of the resources as $109 billion for coal, $248 billion for lignite, $187 billion for oil and $45 billion for natural gas.

Then the question of responsible extraction. The document is concerned with the environmental effects. There are plenty to be concerned about, but in this post I’ll focus on greenhouse gases, which the document addresses in a short section headed “Can We Manage Greenhouse Gas Emissions?”

Powerman: solar PV, net metering and seeing the light in New Zealand

Grid tie solar power is becoming a no-brainer! Photovoltaic (PV) solar power generation has made enormous advances over just the last two years. The cost of panels and assorted gear has fallen dramatically so that in NZ grid tie solar systems in the 2KW peak power range can be purchased for under NZ$10,000 (including GST) from many outfits.

Grid tie PV systems, to make sure its clear what I mean here, are systems consisting of a set of solar panels, often 10 panels of 190W and 45 Volts each, and a grid tie inverter which feeds the solar power into the 240V mains system at your home.

Once installed the power that is generated by the rooftop panels feeds into the 240V mains system. Power required by the home is then derived from this source. If the requirements of the home exceed what’s generated, additional power flows in from the mains and your power meter runs forward as usual. But if your home requires less energy than the panels are generating, often the case on a sunny day, the excess power is fed into the grid and your meter runs backwards, or so it should. More about this below.

Liveblog: Durban down to the wire

3.20 am Sunday morning

The South African Minister took key people into a “huddle” for 10 mins.

“Can the world be saved in a tea break?”  tweeted @FionaHarvey from The Guardian.

Tea Break over… so. They have agreed “to launch a process to develop a protocol, another legal instrument or an agreed outcome with legal force applicable to all parties….” to be negotiated through to 2015 and be implemented from 2020.

Meanwhile, over in the Kyoto Protocol, the EU slipped back and agreed an eight-year commitment period, which would also take that through to 2020.   It’s up to governments to decide whether they want to submit pledges under that process by May next year.

So with the atmosphere in mind, and the steady march to 3.5ºC of warming, there’s nothing much here, yet, to slow that march.  The definition of the “legal” bit of this decision could mean anything – and I can see lawyers around me in plenary already working that out.   Will it be enough to bring the big emitters on board?

Will that be enough for New Zealand to make its pledge unconditional and continue with Kyoto? Or will our government continue to point fingers at the big guys? Given the work that Tim Groser did in watering down the text overnight, I doubt it.

But right now, I’m too tired to puzzle it all out. It’s certainly nothing like the strong climate action we need.

Oxfam NZ Election Debate: Climate change

[youtube]EsR7rdwYQbA[/youtube]

Environment minister Nick Smith, Labour’s David Parker and the Green Party’s Kennedy Graham debate climate policy in these edited highlights from the first of Oxfam NZ’s election debates, held last week in Auckland. Debate ranged from whether New Zealand can become carbon-free to the likelihood of a cross-party agreement on long-term issues that last more than an election cycle, and from the effect of investing in roads to the question of bringing agriculture into the Emissions Trading Scheme (ETS).

More on the debate from Oxfam NZ’s Jason Garman below the fold…
