Searching for ecological nirvana in energy supplies

Posted 14 August 2019 by David Spratt

“A society grows great when people plant trees whose shade they know they will never lie in.” - Greek Proverb I spent the best part of Saturday planting trees, flaxes, and ferns along a stream bank with my son, Tom, and his best mate. The task was “wholesome” according to Tom, as the plantings should facilitate the recovery of a stream that was once badly polluted but now runs mostly clear following positive steps by my dairy farmer neighbor to abide by the Fonterra clean stream accords. As I patted my own back for my newly enhanced green credentials, I turned my...

Sustainability now considered economic and environmental

Posted 7 August 2019 by Chris Hargreaves

New Zealand has set a target under the Paris Agreement to reduce its greenhouse gas emissions by 30% below 2005 levels by 2030, and to adopt increasingly more ambitious targets in the future. Per capita, New Zealand's emissions are one of the highest in the world with an output of <1% of the total world's emissions. Business New Zealand recently released a report which concluded that "opportunities to improve our performance in productivity and renewable penetration lie in every part of the energy supply chain. While productivity and renewables are not necessarily mutually...

Tech That Keeps The Planet Cool

Posted 31 July 2019 by David Spratt

I lit my first fire at home for the year on the unusual date of May 31, just one day before the official beginning of winter. I live in the sunny north side of Auckland, but I would have expected to see my dog sleeping in front of the fire by around late April. There are some of us who believe that to the detriment of future generations the planet is suffering from global warming and others who feel that the scientific consensus is still a long way from being agreed. Either way, I do believe there is a general accord that we can’t keep consuming the planet’s resources at the rate...

Can New Zealand Electrify Industry?

Posted 20 May 2019 by Chris Hargreaves

The Government has set a target for New Zealand’s economy to be net-zero emissions by 2050. Does our current approach stack up? Methanex - adding 15% to national electricity demand? In a recent submission to the Ministry of Business, Innovation and Employment (MBIE), Methanex, New Zealand’s largest single gas user suggested that should the company transition from gas-based manufacturing of methanol to electricity, this would increase New Zealand's national electricity demand by around 15% (5,800 gigawatt-hours). In other words, there would be a Rio Tinto Aluminum Smelter-sized...

Mercury’s pioneering direct grid-connected battery: it’s large and in-charge

Posted 24 September 2018 by Richard Gardiner

During the recent two-day EMANZ Conference that I attended in Auckland with our Energy Manager, Tânia Coelho, I was struck by the surge of genuine enthusiasm for and commitment to renewable energy from the diverse group of Energy Managers and others who attended. In this regard, our country is in the fortunate position that 85% of our electricity supply already comes from renewable energy, mainly hydro-electricity, geothermal and wind-generation based. Successive National and Labour Coalition Governments have made a strong and binding commitment to New Zealand meeting its global carbon...

Caution urged on New Zealand’s ‘gung-ho’ climate change approach

Posted 24 July 2018 by Richard Gardiner

This excellent article in Energy News says it all for me. A reality check which deserves to be published in the mass media! Unlike New Zealand politicians who are only interested in scientific research that validates their particular view of the world, this acclaimed Cambridge University academic knows what he is talking about and has no ideological axe to grind on Climate Change. - Richard Gardiner, Managing Director, Total Utilities. The following article was originally written by Gavin Evans and published on Energy News Michael Kelly has nothing against walkways and cycle...

Solar in a Renewable Based Energy Market

Posted 12 June 2018 by Chris Hargreaves

It is well known that in New Zealand, energy generation is largely renewable. Around 65% of generation is hydro-based mainly in the South Island and around 15% is geothermal based through the central to the eastern side of the North Island. In the following series of articles, we will look at the pros and cons of commercial solar installations in the New Zealand market. During the last National-led Government, there was little emphasis placed on increasing the uptake of large-scale Solar (with the current Labour-led Government this may change) as it was seen merely as converting from one...

Leaking air, leaking bottom line: top money-saving tips

Posted 12 December 2017 by Chris Hargreaves

The following was published in the NZ Herald 25th of November 2017 and includes energy tips from Total Utilities' own Pushkar Kulkarni who reveals how leaking air wastes money. Four energy experts offer top tips to save money Running an air-conditioning unit at full tilt to cool down one part of a building, while a boiler blazes away to heat another part of that same building, sounds like madness - but it's surprisingly common in New Zealand's commercial buildings. It's just one of the ways businesses are squandering energy, and therefore money, in the course of their day-to-day...

Watercare House Case Study: Anchor tenant scores a NABERSNZ excellent rating for energy use

Posted 7 December 2017 by Chris Hargreaves

Pushkar Kulkarni from Total Utilities completed the site review and NABERSNZ Assessment of Watercare House. Here he provides additional commentary to the original published case study, highlighting the specific benefits of a NABERSNZ tenancy rating. "A NABERSNZ tenancy rating is an ideal tool for tenants as it shows them how their day to day operations impact their energy performance. It can also determine how well they manage energy and identify the opportunities that may exist to improve energy performance. In an increasingly competitive market place and businesses look for a point of...
