Submission To: Climate Action For Aotearoa
Although the need for action to limit climate change has been well understood since at least 1990, global CO2e emissions have continued to increase strongly over the past 30 years and only now is the rate of increase showing some signs of deceleration. It has become very clear that, in order to avoid potentially disastrous consequences, we need to limit global warming to 1.5°C above pre-industrial levels. The Paris Agreement, which came into force on 4 November 2016, was a step forward in addressing this very major challenge, but the Nationally Determined Contributions (NDCs) submitted so far are not nearly adequate to meet the target.

Pumped Storage Planning – 1970s VS 2020
Pumped Storage Planning, 1970s vs 2020 By Dr Alastair Barnett Webinar 21 Oct 2020 Until the recent flurry of publicity about the Lake Onslow proposal, pumped hydropower storage had not been seriously considered in New Zealand since the 1970s. At that time the Tekapo canal was under construction to link the two main storage reservoirs (Lakes Tekapo and Pukaki) in the Upper Waitaki power development, and an obvious option was to design the canal to take pumped flow from Pukaki to Tekapo as well as gravity flow from Tekapo to Pukaki. The canal design was duly analysed, constructed and tested to have the required reverse flow capacity. Instead, the newly developed Maui gas field was utilised and the Huntly thermal power station continues in use, and the importation of coal means that our thermal emissions have actually increased. The disastrous outcomes of poor power planning have now been recognised, but the reaction seems to be one of panic, adopting the first scheme to come to mind while ignoring the alternatives, especially the final 10% of the Tekapo-Pukaki scheme.

As a group of professional engineers, Engineers for Social Responsibility (ESR) strongly endorse MBIE’s commitment to meet the government’s Carbon Zero targets by 2050, and the implementation of changes to our Building Consent regulations that will improve operational efficiency and reduce lifecycle carbon emissions from New Zealand’s building stock.

Prof Olaf Diegel of the University of Auckland, spoke to a webinar arranged by Engineers for Social Responsibility on 16 September 2020. Additibve manufacturing is popularly know as 3D printing and has been eagerly seized on by many computer users as an additional and interesting adjunct to their work.

Dr Geoff Bertram spoke to an online meeting of Engineers for Social Responsibility on 19 August 2020. He reviewed the electricity reforms since 1986 and their effects, particularly on pricing, excess profits and anti-competitive practices. He noted the effects particularly on increasing poverty and inequality, specially child poverty and energy poverty. He suggested steps that could be taken to deal with these problems, but noted that invested interests would make implementation of any of them, very difficult to achieve.
