The pie chart above shows that 399 kilotonnes of greenhouse gases came from energy and water, just under a third of all greenhouse gases from the city of Brighton & Hove in 2018.
Why energy is so important
Energy is essential for our city, it:
- provides heat for homes
- powers our transport
- keeps our healthcare system running
To maintain our quality of life, we need to set up an energy supply that is:
- affordable
- locally generated
- green
There are high levels of fuel poverty due to rising energy prices, energy inefficient housing and low incomes.
Living in a cold home with bad ventilation can cause health issues like respiratory problems and depression.
What you'll find in this section
This section covers:
- reducing energy consumption
- providing greater access to renewable energy
- making sure existing homes are affordable and healthy to live in
This means:
- new renewable energy generation technologies
- an engaged community who want to make change
- a focus on new business models that can transform our local energy systems
Why becoming carbon neutral is important
Energy-efficient homes reduce waste energy and the demand for non-renewable energy. They may also be cheaper and healthier to live in.
We can only transition to Carbon Neutral by 2030 if we can remove carbon from our energy and water infrastructure on a bigger scale. So, working at a city region and wider south east region scale will be needed for success.
The council will work closely with partners of the Greater Brighton Economic Board and Greater Brighton Infrastructure Panel to provide ambitious solutions for low carbon infrastructure across the city region.
Greater Brighton energy and water plans
These plans, agreed in 2020, brought together public sector, business and academic stakeholders across the city region.
They identified opportunities for energy and water infrastructure that will support our goals and actions to remove carbon and help economic growth in renewable energy, power, heat and transport.
Learning and sharing information between local councils was important in this rapidly evolving technology, financial and regulation.
Recently, there's an increased focus on the potential to build hydrogen production, distribution and end uses in the city region, particularly for heavy vehicles.
The water plan identified challenges in cutting the amount of clean drinking water we use. This would be to reduce the impacts of the predicted water shortages to the region in the next decade.
Water and wastewater treatment use energy, so cutting how much we use will also reduce carbon emissions.
Existing homes
Energy efficiency in housing and buildings is important in reducing carbon emissions. The council has a role to play in energy upgrades and retrofitting, through:
- organising and coordination
- being a trusted partner
- supporting the growth of local skills and supply chain
The council is developing an extensive plan for:
- solar PV (photovoltaic)
- replacement of heating and hot water
- energy efficiency in council housing
It's also working with residents to change behaviour, where required, and make sure they get maximum benefit from the retrofit programme.
There is significantly more private housing than council housing, so this is where we can make greater carbon savings. Although, this relies more on government action and funding.
To promote the retrofit of private homes, the council is working with partners, including:
- Solar Together Sussex
- Warmer Sussex
- Local Energy Advice Partnership
Council property
The council has been improving its own stock of housing by identifying where energy use is not efficient. It's also been working with site managers to save energy and water and improve the efficiency of gas, electricity and oil use.
In the near future there will be a focus on low carbon heat technology. Surveys will be done in schools and housing centres that may be suitable for this technology. Control and monitoring systems will also be improved.
In 2021 to 2022, a programme to install 500 kW of solar PV in corporate, housing and leisure sites will save 150 tonnes CO2 a year.
The council will transfer its energy supply to renewable sources as existing contracts end.
Challenges
Some of the biggest challenges we're facing are:
- 38% of the city’s carbon emissions are from gas, 26% from electricity
- scaling up energy efficiency retrofit of private homes - rented and owner-occupied - presents long-term, logistical and engagement issues
- heating is difficult to decarbonise, it needs a mix of solutions, heat networks, and long-term programmes to replace gas boilers
- local supply chain for new energy technologies needs to be developed further
- smart energy systems are essential but need complex systems
Key actions
Reduce CO2 emissions from council owned properties
To do this, we will:
- work towards a fully renewable electricity supply in council property
- develop an investment plan for transitioning council buildings to carbon neutral
Building audits will measure opportunities, identify and prioritise planned self-financing energy saving projects on council assets. For example, replacing old lightbulbs with LEDs is expected to pay back the cost of the LED in 4 to 5 years in lower electricity bills.
Energy efficiency and renewable energy projects will be done using the savings reinvested.
The timeframe for this will be short, medium and long term. The impact on CO2 emissions will be high.
We will also:
- deliver a major programme of renewable energy, solar PV and energy efficiency retrofitting on council housing
The impact on CO2 emissions for this will be 1,291 tonnes per year. The timeframe will be medium term.
Reduce carbon emissions from council-owned vehicles
To do this:
- our fleet of council vehicles will become carbon neutral - we will reduce diesel vehicles and plan through delivery of the Fleet Strategy
The impact on CO2 emissions for this will be high. The timeframe will be medium and long term.
Street lighting modernisation
To do this we will:
- replace street lighting with LEDs - this will be part of continuing work on the street lighting modernisation programme
The impact on CO2 emissions for this will be 2,360 tonnes in 2021. The timeframe will be short term.
Improve standards in private housing
To do this we will:
- continue to explore partnerships and urge for investment and solutions for increasing the retrofit of private housing to improve energy efficiency
The impact on CO2 emissions for this will be medium. The timeframe will be long term.
We'll also:
- increase capacity for hazard inspection and Energy Performance Certificate non-compliance
- consider creating a private rented sector team to enforce housing and energy efficiency standards
- support the growth of good landlord schemes
The impact on CO2 emissions for this will be medium. The timeframe will be short term.
Finally, we will:
- address fuel poverty through a programme of energy efficiency in council-owned housing
The timeframe for this will be short and medium term. It will have a low impact on CO2 emissions.
Support a resilient, zero carbon and smart energy system through delivery of the Greater Brighton Energy Plan
