Fresh off completing Pienza Neutral Bay, developer <a href="https://www.apartments.com.au/developers/central-element">Central Element</a> is preparing its next move in the coveted Lower North Shore suburb.&nbsp;

Central Element (CE) has lodged plans for an eight-storey apartment building at <a href="https://www.apartments.com.au/new-apartments/54-64-barry-street-neutral-bay-nsw-2089">54–64 Barry Street</a>, a 1,659 sqm site just south of Military Road and the Neutral Bay town centre.

The $52 million development will involve the demolition of four detached homes across four lots to deliver 45 apartments, including eight affordable housing units to be managed by Bridge Housing. The mix will comprise six one-bedroom apartments, 24 two-beds, and 15 three-beds. The apartments will sit above three basement levels with 62 car parking spaces and 50 bicycle spaces.

<a href="https://www.apartments.com.au/architects/mhn-design-union">MHN Design Union</a> (MHNDU) has returned as architect following its work on Pienza, again shaping a mid-rise form with a clear street presence. The design features a lower four-storey podium element that responds to surrounding context, with upper levels recessed to reduce perceived bulk. Communal open space is proposed both at ground level and on the rooftop, the latter including an outdoor kitchen and swimming pool.

“The building has been designed with a lower four-storey element and with building materials commensurate with the character of the area,” Beam Planning noted in its submission to the North Sydney Council.

Bridge Housing will manage the affordable units for a period of 15 years, as required under the Housing SEPP’s incentive provisions.

MHNDU’s design report further highlights the site's strategic location just 250 metres from key bus stops and 1.3 kilometres from North Sydney CBD, positioning it for transit-accessible housing supply. In their planning justification, the design team emphasised the site’s compatibility with emerging local character and scale.

Central Element has a solid apartment pipeline spread all over Sydney. They recently completed&nbsp;Pienza, 37 apartments just 500 metres away from the new project, and are currently building Ethos Chatswood, Ballamac House in Coogee, and Bianca on the harbour in Drummoyne.

They have plans for future projects in Mosman, Bondi Beach, Greenwich, Lavender Bay, along with a tower on the edge of Hyde Park.

Real estate investment fund Wentworth Wentworth Equities is soon to launch a "Los Angeles-inspired" residential, leisure and lifestyle precinct in Brisbane’s Hamilton riverside ahead of the predicted Olympic-led population explosion for the city.

Drawing its style inspiration and name from Los Angeles’ renowned The Grove, <a href="https://www.apartments.com.au/new-apartments/hamilton-grove-19-hercules-street-hamilton-qld-4007">Hamilton Grove</a> will feature three residential towers and a vibrant street-level public precinct with curated luxury lifestyle, retail and dining offerings.

The first of the three towers, to launch in March 2026, will comprise 61 apartments, in the same building as a premium hotel.<img alt="Hamilton Grove" data-entity-type="file" data-entity-uuid="d227fe61-8392-45b7-b386-9133f29a249f" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-01-19%20at%209.10.56%E2%80%AFAM.png?VersionId=HTCV35HZ4h84jQCmHwhsdIPN0ctO5d7Z" />

Wentworth Equities Executive Chairman Sameh Ibrahim said the precinct will be unique in its appeal to both residents and the wider community.

“Hamilton is already one of Brisbane’s most sought-after riverside suburbs and for good reason,” Ibrahim said.

“Where else in the world can you walk out of your front door and have everything you could possibly need at your fingertips? The city is just around the corner, the airport is only ten minutes away, you have the river and green spaces right there and premium retail and dining on your doorstep."

Wentworth Equities acquired the 7637 sqm Hercules St site in 2014, when Ibrahim said he had a "very clear vision" for the precinct, but ultimately it wasn't the right time to develop. He said Hamilton was still very much an "emerging precinct."

“Since then, Hamilton and surrounding suburbs like Ascot and Albion have significantly grown and matured into a precinct that aligns with our vision for Hamilton Grove. Brisbane as a whole has so much to offer in the way of lifestyle appeal, but as it stands it is so widespread – you go to Howard Smith Wharves for fine dining, you go to James Street for shopping, you go to West End to walk along the river – but what if you could go to Hamilton Grove for everything?

“Our vision is a precinct that brings together the best of Brisbane into one central space abundant with culture, class and culinary experience – a place that a lucky few will get to call home, but the rest of Brisbane still get to explore and experience at their leisure.”

"LA-inspired" Hamilton Grove to launch on Brisbane riverside

There’s a quiet patch of <a href="https://www.apartments.com.au/developments/hawthorn-vic-3122">Hawthorn</a>, between the bustle of Glenferrie Road and the curve of the Yarra, that rarely sees change, and even more rarely, new apartments. But that’s exactly where <a href="https://www.apartments.com.au/developers/pomeroy-pacific-quattro-corp">PQD</a> is planting Kooyongkoot: a deliberate, 18-residence answer to the question of what downsizers actually want.

“This is something this pocket of Hawthorn has never seen before,” says Fil Gacesa, head of sales at PQD. “<a href="https://www.apartments.com.au/new-apartments/kooyongkoot-hawthorn-1-kooyongkoot-road-hawthorn-vic-3122">Kooyongkoot</a> will deliver just 18 large-scale apartments in the heart of Hawthorn. It is the true definition of resort-style living.”

That scale is central to the story. It’s what allows for two dedicated lift cores, short corridors, and a generous lightcourt that draws natural ventilation and sunlight into every residence. It’s also what makes room for the sort of amenity usually confined to high-density towers: a fully equipped wellness centre with infrared and traditional saunas, yoga and pilates studio, cold therapy shower, and treatment room. There’s a golf simulator, car and dog wash stations, and extensive storage too, not bolted on, but baked in from the start.

But more than the checklist, it’s the design intent that carries weight. “This project has been many years in the making,” says Mark Pomeroy, Director of PQD. “Not just in planning, but in listening, to what our buyers and the local community are looking for”.

[smartcode_project:default project_id=102717 project_image_fid=355289]

That listening shows up in the materials, oak floors, natural stone, V-ZUG appliances, and in how space is handled. Penthouses feature private rooftop terraces with pools. Terraces and garden residences embrace outdoor connection. Inside, the layouts skew large and open, geared for hosting, not just housing.

Architecturally, <a href="https://www.apartments.com.au/architects/cera-stribley-architects">Cera Stribley</a>’s approach is grounded. There’s no reaching for spectacle here. Instead, the building offers a sculptural calm, anchored by landscaping from Eckersley Garden Architecture.&nbsp;

“We wanted to create spaces that feel expansive, serene, and meaningfully connected to daily life,” said founding partner Chris Stribley elsewhere.

[smartcode_project:default project_id=102717 project_image_fid=355304]

That sentiment, calm, connection, echoes in the location itself. Kooyongkoot sits just a short stroll from Central Gardens, Fairview Park, and the Rivoli Cinema. Tram lines and schools are close, but the street is tucked, quiet, and leaf-lined.&nbsp;

“Residents of Kooyongkoot will be a short stroll from Fairview Park, Central Gardens, and the Glenferrie Road retail strip," Gacesa notes, "but you're also cocooned in this peaceful pocket behind extensive landscaping by Eckersley Garden Architecture.”

Kooyongkoot is set for completion in late 2026.

The project that said no to compromise: Inside Kooyongkoot, Hawthorn

When long-time Ivanhoe locals Graeme and Catherine, decided it was time to downsize, they weren’t necessarily in a rush.&nbsp;

Like many in their stage of life, they had started thinking about apartment living, but anticipated making the shift in two to three years.

That timeline changed when they visited <a href="https://www.urban.com.au/new-apartments/candela-ivanhoe-40-upper-heidelberg-road-ivanhoe">Candela</a>, a new boutique development by <a href="https://www.urban.com.au/developers/salter-brothers">Salter Brothers</a>. The project ticked all the boxes they were looking for: location, quality design, and long-term lifestyle benefits, which prompted them to bring their decision forward.

“It was the right place at the right time,” they said. “We knew immediately it ticked all the boxes, and we didn’t want to wait.”

[smartcode_project:default project_id=342 project_image_fid=358855]

Their decision to downsize was driven by a combination of practical needs and lifestyle considerations. Their existing home, while much loved, had become increasingly difficult to maintain. It spanned multiple levels, included extensive front and back gardens, and was starting to show the wear that comes with age.&nbsp;

They were looking for a more manageable lifestyle, one with less upkeep and more freedom. A brand-new apartment with no maintenance requirements and the ability to simply “lock up and leave” gave them peace of mind and a greater sense of control over their future.

Financially, the purchase made sense as well. The available stamp duty savings, strong price-to-value offering, and timing of the settlement suited their plans, making the transition smoother and more cost-effective. The apartment's design and inclusions further supported their choice.

[smartcode_project:default project_id=342 project_image_fid=357493]

The layout was both functional and flexible: three bedrooms, a butler’s pantry, a separate laundry, and a large open-plan living area. It gave them the freedom to host a family, accommodate guests, or set up a home office. The expansive balcony and elevated views added to the appeal, providing a sense of openness and connection to the outdoors.

“It just had a really good flow,” Catherine noted, something they found lacking in many other apartments they’d considered, particularly in the established market.

Candela’s boutique scale was another deciding factor. With a smaller number of residences and a top-floor penthouse position, the couple felt the development offered the privacy and space they were looking for, without feeling isolated.

“We liked that it wasn’t a huge development. It felt well-balanced, modern but still with a sense of community, not overwhelming,” they said.

[smartcode_project:default project_id=342 project_image_fid=357508]

Equally important was the ability to remain in Ivanhoe, a suburb they know well and have deep roots in. After 46 years in the area, proximity to local parks, shops, and familiar faces mattered just as much as the apartment itself.

“We didn’t want to give up the community we’ve known for decades. Candela allowed us to upgrade our lifestyle while staying in the place we call home.”

With a Walk Score of 90, the village location supports a convenient, connected lifestyle. <a href="https://www.apartments.com.au/developments/ivanhoe-vic-3079">Ivanhoe</a> Station is just a eight-minute walk away, and the neighbourhood offers access to parks, cafes, restaurants, and schools along Upper Heidelberg Road, all within easy reach.

Beyond the apartment, the couple also saw value in the broader vision for Candela, one that integrates residential living with public spaces and local amenities.&nbsp;

The development introduces 58 new apartments as well as a mix of commercial and social spaces that integrate contemporary architecture with the suburb’s existing character.&nbsp;

At ground level, residents will find a charming café and a lifestyle wellness centre, perfect for unwinding and rejuvenating. Meanwhile, the rooftop garden offers a stunning vantage point for residents to enjoy breathtaking sunsets, host gatherings, or enjoy barbecues with family and friends. It's not just a place to live; it's a vibrant community where every moment is an opportunity to connect and create lasting memories.

Why Ivanhoe locals are choosing to downsize to Candela

Mark and Roy Makari are expanding their presence in Sydney’s South West with a second major proposal for Leppington, this time envisioning a 900-dwelling mixed-use development just 850 metres from their previously lodged tower trio on Fifth Avenue.

Project management and construction management firm Creative Vision filed the plans for the&nbsp;multi-building project at <a href="https://www.apartments.com.au/new-apartments/230-rickard-road-leppington-nsw-2179">230 Rickard Road, Leppington</a>. The proposal seeks to establish a new focal point for the precinct through a high-density, transit-oriented development supported by diverse land uses.

According to the Scoping Report prepared for the Department of Planning, the scheme includes around 900 apartments across multiple towers, including 135 dwellings designated for affordable housing. A mix of market and subsidised apartments will be supported by ground-level activation through retail and office space, a childcare centre, and a hotel, forming a comprehensive urban precinct.

<img alt="Mixed Use Development 230 Rickard Rd Leppington" data-entity-type="file" data-entity-uuid="34797362-f3dc-4d84-8235-2657fc5f3bde" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Plan.png?VersionId=Uzckrz9tUpDQl5lX1_WMhjnv16bsr8wG" />

The Design Report by <a href="https://www.apartments.com.au/architects/studiosc-0">Studio SC</a> notes that the project “intends to deliver a high-quality, high-density built form that supports the vision for the Leppington Town Centre, integrating mixed-use outcomes and public domain upgrades.” The development is expected to be delivered in stages, although a precise timeline is yet to be confirmed.

The project will be assessed through a future State Significant Development Application, with the Scoping Report indicating the team will seek design excellence via a competitive process or through an expert design review panel. Early massing diagrams suggest a series of mid- to high-rise buildings framing a central landscaped spine, with emphasis on pedestrian permeability and public space.

The planning documentation flags a strong sustainability agenda, stating that the development will “respond to the urban heat island effect, incorporate water sensitive urban design, and prioritise active transport”.

<img alt="Mixed Use Development 230 Rickard Rd Leppington" data-entity-type="file" data-entity-uuid="369d7b54-1279-4cde-88ec-dcb215594414" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Podium_1.png?VersionId=QArL7B2kkLt63vl5xvL0FNV_ardAlez4" />

The proposal follows in the footsteps of the Makaris’ nearby Fifth Avenue site, where they’ve submitted plans for three towers comprising nearly 500 apartments, with 10 per cent dedicated to affordable housing. That project features commercial podiums, a childcare centre, and a new public park that would occupy more than a third of the site.

Both developments are situated within walking distance of Leppington Train Station and fall under strategic precinct plans promoting higher density housing. The town centre is undergoing substantial transformation, driven by state government planning reforms aimed at fast-tracking housing delivery.

Together, the two projects represent a combined ambition of nearly 1,400 new homes across just under two kilometres of central Leppington.

Wind Farm

<html><body>
UBS Asset Management has sold their stake in Collgar Wind Farm, Western Australia's largest wind farms, to REST Industry Super.
REST had owned 40 percent of Collgar and have acquired UBS Asset Management's 60 percent stake.
The deal will make Collgar one of the largest Australian renewable energy projects directly owned by an Australian superannuation fund.
Rest has been involved with Collgar since construction began in 2010. 
Collgar generates, on average, between 40 and 50 per cent of the state’s renewable electricity. This is enough to power up to 170,000 average WA households per year and displace up to 690,000 tonnes of carbon dioxide emissions per year. 
<div class="page" title="Page 1">
<div class="layoutArea">
<div class="column">
The acquisition was negotiated by Rest’s internal investment manager, Super Investment Management. 
</div>
</div>
</div>
 George Zielinksi, chief investment officer at Super Investment Management, said the project is expected to continue to generate sustainable cash flows.
<div class="page" title="Page 1">
<div class="layoutArea">
<div class="column">
“Collgar Wind Farm is a premium infrastructure asset that has been delivering strong returns for Rest members", Zielinski said.
<img src="https://res.cloudinary.com/dz9xllyip/image/fetch/c_scale,w_580,q_auto:good/https://s3-ap-southeast-2.amazonaws.com/po.images/2019/6/24/Colgar%20Wind%20Farm%203.jpg" alt="">
"Renewable energy projects like this will continue to play an important role in Australia’s future.
“As an existing owner, Rest has been able to monitor and assess the wind farm’s operational performance since construction was completed in 2011. 
"Taking full ownership is a great opportunity to drive further value from the asset and strengthen Rest’s infrastructure portfolio. 
"We are confident it will help grow members’ retirement savings into the future.” 
Collgar is the largest wind farm in WA, built on 18,000 hectares of land with a total capacity of 206 Megawatts. 
Collgar generates, on average, between 40 and 50 per ent of the state’s renewable electricity, enough to power up to 170,000 average WA households per year and displace up to 690,000 tonnes of carbon dioxide emissions per year. 
The project holds a five-star Global Real Estate Sustainable Benchmark (GRESB) rating for 2018.

DomaCom have been selected by developers CWP Renewables and Partners Group as their partner to implement the community co-investment initiative of Sapphire Wind Farm in rural New South Wales.
The Sapphire Wind Farm, in Kingsland New England in Northern New South Wales, will be an Australian first for its community co-investment.
DomaCom's <a href="https://domacom.com.au/" target="_blank">fractional property platform</a> will allow local community members to invest alongside institutional investors.
The platform allows multiple investors to aggregate their investments into an asset, typically a real estate asset, but now also renewable energy projects.
Andrew Dickson at CWP Renewables, the company behind developing and constructing the wind farm, said DomaCom is a great fir for the community co-investment initiative.
"Their online platform makes it very easy for people to establish and manage their investment," Dickson said, adding that after testing the community's interest late last year, he was surprised with the level of interest.
“With over $7.3m of pledges received so far from the local community, we are pleased to now be delivering on our promise to the community, to open up the project for co-investment.”
Ross Laidlaw from DomaCom said the company are excited about the partnership.
“We are very excited to be partnering with CWP Renewables and Partners Group in the Community Co-Investment Sapphire Wind Farm. DomaCom has been a pioneer in fractional investment in Australia now in its 5th year of operation.
"The Sapphire Wind Farm Community Fund is a clear demonstration of the vision of DomaCom taking large institutional assets and breaking them down into fractional components to allow retail investors to obtain exposure to an asset class not previously available.”
Construction of the wind farm began in January, and the final turbine was installed in October. 
Ben Haan from Partners Group, the investment fund manager that co-owns the project, said community investment is integral to the business.
"What we are pioneering at Sapphire will be applied to future Grassroots projects, allowing our communities to share the benefits and to invest in Australia’s renewable energy future," Haan said.

GUEST OBSERVER
While Australia’s energy market operator continues its investigation into South Australia’s recent state-wide blackout, there are important questions being asked. 
For instance, was extreme weather the only cause? Has South Australia replaced fossil fuels with renewables too quickly?
And is the Australia’s Renewable Energy Target (RET) too ambitious all together?
It is impossible to find answers without understanding how the energy market works, and how replacing one source of energy with another actually happens. 
<h2>How does the market work?</h2>
Most Australians (barring the Northern Territory and Western Australia) get their electricity through the National Electricity Market. 
Suppose all the energy users, at a particular day and time, switch on lights, computers, industrial machinery, washing machines, vacuum cleaners, traffic control equipment and more. Added together, they determine how much energy is needed or demanded at that very point in time. 
On the other side of the poles and wires, different independent electricity generators – thermal, hydro, wind, solar – are offering energy to the market, each at a price enabling them to recover costs and make a reasonable profit. This is called bidding. 
Contemporary electronic technology allows for the wholesale market to take electricity and bids every five minutes, and allocate amounts accepted from the successful bidders. And who are those successful bidders?
All current bids are ranked by unit price. Allocation starts from the lowest-price bidder, then the second lowest one, and continues on until the current demand is met. The last accepted bidder’s price becomes the spot market price, and allows other successful bidders to make more or less profit.
<h2>How do renewables affect the market?</h2>
The main incentive policy for wind farms in Australia is the Renewable Energy Target (RET), which legislates that 33 gigawatt hours of electricity must come from renewable sources by 2020. As part of the RET, large-scale renewable energy generators (solar and wind farms) receive credits (certificates) for electricity they generate, which are then purchased by retailers to meet the target. 
This market is separate to the National Electricity Market (NEM) and acts as a second income source for renewable energy generators.
With this in mind, we have modelled what happens when wind energy is phased into the market based on five minute electricity market data for several years.
The running (marginal) cost of wind generators is zero (because wind is free), unlike traditional thermal technology (which has to pay for coal and gas). Subsequently, wind generators recover their fixed costs and obtain profit in the difference between marginal cost and market price based on “more expensive” bids. 
In the long run, wind generation decreases the market price through the bidding process. So with an increase in the energy volume generated by wind, the traditional sources are pushed out from the market. The chart below illustrates this process for South Australia. 
<a href="/images/2016/10/25/image-20161019-20308-xt2ui.jpg" target="_blank">Click to enlarge</a>
<h2><img src="/images/2016/10/25/image-20161019-20308-xt2ui.jpg" alt=""></h2>
Because their fixed costs can be recovered through the RET, wind generators can bid at near zero prices and completely eliminate traditional competitors. Therefore, wind generation can only naturally exist in the market if there are other, more expensive forms of generation to set the price. Otherwise wind farms could not recover their costs without the RET. 
This means that there is an optimal proportion of wind energy in the market, where more expensive thermal generators set the market price. 
If there is an optimum amount of wind energy in the market, this has important consequences for the RET. The target artificially increases the proportion of wind energy that can be sustained in the grid. While this may be the goal of the RET, without the incentive, wind capacity would eventually fall back to the market optimum. 
In practice, this would occur as wind farms reach their natural life of about 20 years and aren’t replaced. So the RET won’t maintain or increase wind energy in the market in the long term, unless the incentives continue indefinitely.
The current RET is legislated to 2030, with a target set for 2020. To encourage wind energy in the long term, it would be required, then, to support the RET by an ongoing financial inducement without a closing date. 
Without any financial inducement, wind farm developers would not increase capacity beyond the optimal point, and some thermal generation will continue to exist. Thermal generation can be completely excluded only if all the fixed costs of wind energy can be recovered through the RET. This is impractical and beyond the intentions of the policy. 
So as it stands, our modelling suggests the RET is not a good way to increase the amount of wind generation in the electricity network. However our conclusions are different for other renewable energy sources such as hydro, which also have near zero marginal costs but have much longer lifetimes.
Therefore, where and if possible, we need to use a mix of technology, rather than overemphasising wind generation technology.

Are wind farms messing up the electricity market?

<html><body>
GUEST OBSERVER
The debate about wind farms is clearly not over yet.
Last week Australia’s National Heath and Medical Research Council awarded A$3.3 million to fund two new health studies: one to measure the effect of infrasound on sleep quality, balance, mood and cardiovascular health; the other to determine whether low-frequency sound from wind farms can disrupt sleeping patterns.
Given the past few years of prickly wind turbine politics, this has predictably caused quite a stir.
On one side, the usual suspects sought to capitalise on the NHMRC’s announcement. Independent senator John Madigan called for a moratorium on new wind farms, wanting all projects to be put on hold as a “precaution”.
Coalition senator Chris Back leapt to support his call, perhaps unsurprisingly given that he (along with Madigan and fellow senators Nick Xenophon, David Leyonhjelm and Bob Day) have been described by Sydney University public heath professor Simon Chapman as “sworn enemies of infrasound".
In contrast, many in the scientific community expressed their disappointment at what they see as a waste of millions of research dollars. They referred to studies from around the globe that have consistently failed to find solid evidence for a connection between infrasound and poor health.
However, funding further research on the possible health impacts of wind turbines is consistent with the NHMRC’s own conclusions in a February 2015 statement, which said:
"Given [people’s] reported experiences [of ill health] and the limited reliable evidence, NHMRC considers that further, higher-quality research is warranted."
So the nation’s largest, most respected and most trustworthy medical research funding body actually agrees that more research is a good idea.
<h2>Down tools?</h2>
Tempting though it is, this piece isn’t about rehashing the current evidence of the health impacts – real or imagined – of wind turbines. That’s been done already and will clearly continue for a while yet.
What’s more interesting, to me at least, is this appeal for a moratorium, and the more general question of how useful a tool it is for making decisions about overtly science-based issues.
Madigan’s call is a typical invocation of the precautionary principle. This asserts that if there are reasonable (that is, evidence-based, scientific) grounds to believe something new might be unsafe – or at least presents risks that unacceptably outweigh the potential benefits – then we should not proceed with the new thing.
On the surface, it’s hard to argue with that.
But when it comes to wind turbines, there is nothing to suggest that Madigan, Back and like-minded folks will consider any level of risk acceptable.
Imagine for a moment that these new studies find no statistically defensible evidence to link infrasound to human ill-health. Will those calling for a moratorium accept the results and declare wind turbines safe (or at least safe enough to lift a ban)?
I suspect not. It looks to me as if what they are actually demanding is “proof of safety”, rather than evidence of “acceptable risk”. This is, of course, impossible. To use an oft-quoted example, we can’t prove that orange juice is 100 percent safe, yet it remains defiantly on our supermarket shelves.
I’d wager a year’s salary that Madigan and friends would declare any “acceptable risk” results to be insufficient, too short-term, or generally just biased and inadequate, and demand that yet more research is done.
The naysayers are not looking for counter-evidence to their claims, most probably because there are things about wind farms that they simply do not like. If they have been unswayed by the research showing no evidence of harm so far, it seems unlikely two more studies will change their minds. 
But what about us down at the science end of town? As noted on The Conversation last year by my colleagues Jacqui Hoepner and Will Grant, “if a credible, scientifically rigorous study were to show a link between wind turbine operation and health effects, it should absolutely be taken seriously”. Agreed!
So for argument’s sake, let’s imagine that these new studies do end up producing empirically valid results that clearly suggest that infrasound from wind turbines can cause people harm. Would we science-loving citizens be prepared to bow our heads and accept the evidence; to admit that Madigan and his cohorts did the right thing by calling for a moratorium?
I’d like to think that I would. But I also imagine myself demanding more research, and I’m confident most other science-positive folks would, too. In our defence, though, we would of course be looking for evidence confirming the existence and likely extent of the harm, rather than seeking proof of some mythical, absolute guarantee of safety.
<h2>Precautionary tale</h2>
So what good will more, precautionary-principle-inspired science do? In reality, probably very little.
For one thing, practical, policy-related action can rarely wait for “all” the evidence to be in before decisions are made and actions taken (assuming such a magical, perfect-evidence situation could ever arise). Invoking the precautionary principle is not likely to simplify this situation.
Far from making decisions more evidence-based, the calls for a precautionary approach are liable to entangle us more deeply in the politics of decision-making. It’s blisteringly naïve to believe that when applied “correctly”, the precautionary principle will refocus warring factions’ attention on noble considerations like gathering sufficient, acceptable evidence and using this to guide us to the most objective solutions.
In fact, it’s arguments over what constitutes the right kind – and sufficient amounts – of evidence that lie at the heart of such disagreements, not what the evidence itself shows. Many people call for evidence-based policy – but when it’s the evidence itself that is up for debate, it’s important (as my colleague Will Grant has quipped) actually to have evidence-based evidence.
So how will this issue play out from here? Here’s my guess:
• a moratorium will probably not be called
• the new research projects will be conducted
• based on current available evidence, they will probably find little to support the idea that wind turbines located more than than 1,500 metres from humans have measurable negative health effects
• scientists will say “I told you so”
• Senators Madigan et al, should they still be around, will call for yet more research.
