Bold 2020 target comes with high price

Hon Dr Nick Smith
Minister for Climate Change Issues
4 August 2009 Media Statement
Bold 2020 target comes with high price

Achieving 100% renewable electricity by 2020 would cost $17.5 billion, put power prices up by 30% and require the equivalent of seven Clyde Dams being built, Climate Change Minister Nick Smith says.

Dr Smith was responding to claims by the Sign On -40% by 2020 campaigners who have stated that “100 per cent renewable electricity supply is easily achievable by 2020”. The Minister tabled the analysis by the Ministry of Economic Development in Parliament in response to questions from the Green Party promoting the -40% target.

”It would first require writing off $4.5 billion of thermal generation assets It would also require $11 billion for the replacement capacity of 2500 MW and an additional $2 billion for additional renewable peaking stations to ensure security of supply in a dry year.

“This amounts to a total capital cost of $17.5 billion, excluding the additional transmission investment that would be required, and would lead to a 30% power price increase for all consumers.

“To achieve 100% renewables we would need to build a total of 3123MW to maintain security of supply – the equivalent of seven Clyde Dams within a decade.

“I have also seen proposals from those campaigning for a 40% reduction in emissions by 2020 who say that agricultural emissions can be reduced dramatically through adopting a ‘Smart Farming’ approach. These methods entail a one-third reduction in stock intensity which would reduce emissions accordingly.

“However, the consequences for New Zealanders of cutting by a third our stock number of sheep, cattle and deer would cost 47,000 jobs, reduce our export receipts by $6 billion and would significantly reduce the living standards of all New Zealanders.

“Such policy options for agriculture are not being considered. Our efforts are going into investing in technologies that will reduce emissions while maintaining farming returns.

“It is misleading for those advocating bold targets to say that 100% renewables and big cuts to agriculture emissions can be easily made. We need an ambitious but achievable goal for 2020 that balances the environmental risks of climate change with the economic impacts on New Zealand of reducing emissions.”

Gordon Campbell: On How Climate Change Threatens Cricket‘s Future

Well that didn’t last long, did it? Mere days after taking on what he called the “awesome responsibility” of being Prime Minister, Christopher Luxon has started blaming everyone else and complaining that he's inherited “economic vandalism on an unprecedented scale” - which is how most of us would describe his own coalition agreements, 100-Day Plan, and backdated $3 billion handout to landlords...

Public Housing Futures: Christmas Comes Early For Landlords

New CTU analysis of the National & ACT coalition agreement has shown the cost of returning interest deductibility to landlords is an extra $900M on top of National’s original proposal. This is because it is going to be implemented earlier and faster, including retrospective rebates from April 2023. More

Green Party: Petition To Save Oil & Gas Ban

“The new Government’s plan to expand oil and gas exploration is as dangerous as it is unscientific. Whatever you think about the new government, there is simply no mandate to trash the climate. We need to come together to stop them,” says James Shaw. More

PSA: MFAT Must Reverse Decision To Remove Te Reo

MFAT's decision to remove te reo from correspondence before new Ministers are sworn in risks undermining the important progress the public sector has made in honouring te Tiriti. "We are very disappointed in what is a backward decision - it simply seems to be a Ministry bowing to the racist rhetoric we heard on the election campaign trail," says Marcia Puru. More
