Decarbonising the world’s energy systems via the deployment of renewable energy infrastructure is one of the most impactful things we can do to protect communities and the environment from the devastating impacts of unmitigated climate change.

While wind energy infrastructure remains essential to support the world’s energy needs, a considered focus on avoiding and minimising impacts in the development and delivery is key to achieving the transition to renewable energy. In many Asia Pacific countries it is already legislated that any proposed wind farm projects demonstrate where and how efforts have been made to avoid or minimise impacts through the planning and design process.

There is a complex challenge as countries work towards net zero and decarbonisation targets, while also avoiding and minimising impacts on communities and the environment.

This fact sheet compares some of the impacts associated with the technical aspects of wind farm projects, and explores ecologically sensitive design that can minimise and mitigate such impacts. Two infographics are included that provide comparisons between the following scenarios:

Scenario 1: Developing wind farms with a standard approach to environmental assessment
Scenario 2: Developing wind farms with environment and community disturbance mitigation as a key focus

Four key mitigation areas

Four key areas to mitigate impacts on wind farm projects 

To reduce disturbance to the environment and communities, wind farm projects need to be developed with minimisation and mitigation in mind. If ecological values are determined early, routes and siting can be optimised and approvals can be obtained in a timely manner.

Actions that can be taken across key mitigation categories include:

Biodiversity	Technology	Route planning and siting	Approvals
Micrositing access roads around ecologically sensitive areas, away from key habitats and individual vegetation Minimising factors that may attract species to turbine locations Blade marking to improve visibility to diurnal bird species Acoustic deterrents to reduce the risk of collision for microbats Implementing turbine-free buffers around areas that provide key breeding, roosting or foraging habitat for significant fauna species Harmonise with the surrounding land used for agriculture	Blade manipulator technology to raise turbine blades when navigating tight turns during transport, to reduce disturbance to vegetation Raising the minimum turbine rotor swept area height to reduce the likelihood of turbine collision by avifauna, particularly microbats Employing alternative crane technology such as tower cranes that are smaller and result in smaller hard stands and assembly areas, thereby reducing disturbance to vegetation On demand shutdowns using smart technology to reduce potential impacts to raptors and other at-risk bird species Low wind speed curtailment to reduce the risk of collision to microbats	Planning alternative site logistics such as just-in-time delivery of turbine components such as blades, resulting in reduced laydown area construction, and overall ecological disturbance Choosing development locations which balance great positive environmental and social outcomes (least impacts) with capital return Possible optimisation of civil design and electrical design to minimise disturbance footprints, such as steepening earthwork batters and including retaining structures in steep terrain Depending on geology, cabling may be installed underneath access roads, or within the access road corridor, therefore reducing earthworks	Taking into account designation of natural assets for impact reduction or mitigation Construction methodology: using energy-efficient machinery, reducing waste, and recycling materials, ongoing monitoring, and use of local materials Layout planning that avoids native vegetation, prioritising retention of areas of highest ecological significance Early engagement with communities to contribute to positive social value outcomes

Standard approach versus minimisation, mitigation and early investigations

Wind farm projects that focus on optimising routes, the accuracy of earthworks and maximising of siting will benefit from positive community and environmental outcomes.

Scenario 1: The standard approach to environmental assessment

Scenario 1 shows the impacts associated with the technical aspects of wind farm developments when actions are not taken to minimise or mitigate disturbances to the environment and communities.

Scenario 1: Developing wind farms with a standard approach to environmental assessment.

*Hardstand areas vary between projects, with some areas rehabilitated post-project, or different sizing depending on construction methodology.

Impact of earthworks on high value environmental area

Hardstand area is large – up to 50 per cent more than scenario 2

Crews might be present for relatively longer timeframes during construction

Impacts on native vegetation, trees, geology and soils mostly connected with access roads and civil works

Environmental and community impact

Approvals: Protracted environmental and planning approvals

Timing: Extensive delay in approvals and project start

Costs: Increased offset costs

Scenario 2: Environment and community disturbance mitigation

Scenario 2 shows the impacts associated with the technical aspects of wind farm developments when actions are taken to reduce disturbances to the environment and communities.

Scenario 2: Developing wind farms with environment and community disturbance mitigation.

*Hardstand areas vary between projects, with some areas rehabilitated post-project, or different sizing depending on construction methodology.

Reduced energy use, waste, materials

Less impacts on geology, soils and natural drainage than scenario 1

Avoidance or impact minimisation on vegetation and trees

Less impact on birds and bats using detection and operational technology applications

Improving biodiversity outcomes, even achieving nature positive

Environmental and community impact

Approvals: Streamlined environmental and planning approvals

Timing: Reduced delay in approvals and project start

Costs: Reduced offset costs

What does this mean for wind energy developments?

There are complex and sensitive considerations that investors and developers of wind energy projects need to work through to achieve approval. The design and construction for any individual project depends on multiple factors and needs to be done with sensitivity and empathy for the directly impacted landowners, communities, and the environment.
