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.

The verdict on Durban – a major step forward, but not for ten years

In this guest post, Mark Lynas, author of Six Degrees, High Tide and The God Species, advisor to the president of the Maldives, analyses the outcome of the Durban conference and what it means for the future of international climate negotiations. It’s one the best and most detailed accounts I’ve come across, from someone at the heart of the action. This article was first published at his personal blog.

Following the marathon negotiations session at Durban, all the delegates should now be back home – and if not quite rested, certainly ready to assess the outcome with the benefit of some distance. In this (rather long) post I will look at the key documents agreed in the Durban outcome, and try to offer some sense of what they mean for the climate regime, and for the climate. (Apologies for some jargon, and for unexplained acronyms, which should be familiar to anyone following the negotiations, and without which this post would be even longer still.)

The Durban mandate

During the second week of COP17 the South African presidency operated an ‘Indaba’ system of high-level meetings, where an options paper was gradually whittled down into a decision text on the crucial issue of the future legal form of the UNFCCC regime. Various iterations of this paper produced some rollercoaster ups and downs from the perspective of a small islands state delegate (as advisor to the President, I once again joined the Maldives delegation). The final version, agreed in the small hours on Sunday 11 December — nearly 48 hours after the COP was supposed to have concluded — is titled ‘Establishment of an Ad Hoc Working Group on the Durban Platform for Enhanced Action'(PDF link).

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.

The counsel of failure: Greenhouse Policy Coalition on Durban

“There is a danger that, in trying to encourage major emitters to sign up to a new agreement or to bridge the Kyoto legal gap, New Zealand might commit itself to something short of a global deal that binds us to making economic sacrifices which are not reflective of fair burden sharing.” So wrote David Venables, executive director of the Greenhouse Policy Coalition, in the NZ Herald this week.

I described the Greenhouse Policy Coalition in a post last year, but I’ll briefly recap. Its members come from a range of New Zealand industry and sector groups covering the aluminium, steel, forestry (including pulp and paper), coal, dairy processing and gas sectors. They include Fonterra, NZ Steel, the Coal Association, Solid Energy, NZ Aluminium Smelters Ltd and others. They are not deniers of climate change and express the cautious opinion that “there is sufficient scientific evidence to warrant the adoption of appropriate precautionary public policy measures”. However their emphasis is strongly on policy which protects what they regard as New Zealand’s international competitiveness.

Call the COPs: Neville Chamberlain only went to Munich once

Simon Johnson discusses the Durban UNFCCC international climate negotiations through the historic lens of the Second World War and the Rio 1992 Earth Summit.

In a very considered comment at Hot Topic yesterday, David Lewis questions whether the Durban UNFCCC international climate negotiations can come up with a binding treaty that effectively reduces greenhouse concentrations, given the existing public will.

“I don’t see how negotiations on an international climate treaty can proceed to an agreement that would actually stabilise the composition of the atmosphere at a level that would not cause [dangerous anthropogenic interference] without more demand for such an agreement coming from the global population”

Lewis compares the public world-wide demand for action in the international climate change negotiations with the changing British attitudes to ‘Total War’ with Hitler’s Germany in 1940. Lewis implies that in the climate change negotiations, each government is “trapped in a circumstance where it can’t generate the national will that’s necessary”.
