We recently worked with a regional council to provide their senior management and other key stakeholders with input to the development of their climate change action plan and target-setting process.
An important part of our work was to show council, based on our experience with many other local governments, what different carbon reduction scenarios look like in this sector. In particular, we showed what a no-action scenario would mean for electricity demand, what a focus on demand reduction within council operations would look like, and what an approach that encompasses both aggressive demand reduction and a comprehensive renewable energy supply strategy could achieve.
Presenting and workshopping these scenarios helped our client to set ambitious goals for energy and carbon reduction that are achievable, affordable and can be planned and resourced in the short, medium and long term.
Three scenarios for electricity-based emissions
To illustrate how inaction and action to mitigate climate change can influence emission reductions over time, we created a series of animations. Please click on the video (< 4min) below to view the effect of energy efficiency and renewable energy measures on a council’s business-as-usual electricity consumption.
Scenario 1: no action
For most local councils, rising population, asset upgrades and service improvements are factors that influence the energy demand of council operations.
In the absence of clear policies and practices to reduce energy demand and increase renewables, these factors will lead to increased energy use. As electricity prices also rise, this will result in higher energy costs over time.
Scenario 2: action within council operations
In most organisations, there are numerous opportunities to reduce energy demand and increase onsite renewable energy.
- Upgrading building lighting systems, air conditioning controls and installing rooftop solar panels usually have an attractive payback.
- Incorporating lowest life-cycle cost technologies and solar into new developments, and implementing sustainable procurement policies for appliances and office/IT equipment can reduce or reverse energy growth over time.
- Replacing capital-intensive equipment such as air conditioning systems, water & sewer pumping systems, sporting field lighting and servers with best-practice energy-efficient technologies can similarly reduce or reverse growth in energy demand.
- Street lighting is often one of the largest energy-using accounts in a local council. As LED technology becomes available, local and main road lighting can be upgraded, leading to large energy savings.
Planning, scheduling and funding implementation of these opportunities over time will lead to a sustained and cost-effective reduction in a council’s grid energy consumption.
However, for most councils, these actions will only take climate mitigation so far, typically a 30% to 40% reduction over time. This would likely fall short of the 2018 IPCC report on ‘Global Warming of 1.5 ºC’, which states that we need to reduce global net anthropogenic CO2 emissions by about 45% from 2010 levels by 2030.
Scenario 3: ambitious action on energy demand and supply
In our experience, it is not possible for a council to achieve deep emissions cuts without focusing on both energy demand and energy supply. In an ‘ambitious action’ plan, there will be a more aggressive rollout of energy efficiency and renewable energy measures, as well as an energy procurement strategy that will source renewable energy for council’s operations.
Energy demand action will:
- Extend solar PV to more marginal sites,
- Develop a plan for larger-scale onsite solar with battery storage,
- Incorporate smart controls with street lighting,
- Plan for charging of electric vehicles over time, including passenger and commercial vehicles and road plant
Energy supply action will include renewable energy purchasing as part of a council’s normal energy procurement process. Typically, this takes the form of a renewable energy Power Purchase Agreement (PPA) as part of overall energy supply, with the potential to scale up renewable energy purchasing towards 100% over time.
For some councils, building their own solar farm may be another way to scale up supply-side action on renewables.
Ambitious action that focuses on both energy demand and renewable energy supply is aligned with global targets to decarbonise by mid-century. As leaders, local governments have an important role to play in showing their communities that deep cuts in emissions are possible and affordable.
You can read more about achieving ambitious targets in our ‘How to achieve 100% renewable energy’ paper.
Ambitious action is achievable and cost-effective
It is possible to achieve ambitious targets cost-effectively – what is required is to plan and resource ahead, to understand the cost implications as well as the cost savings, and to know what measures can be rolled out at what point in time.
