Renewables are powering the UK’s drive to Net Zero
In less than a decade, renewable energy has gone from an expensive but climate friendly alternative energy source to the foundation for a future UK energy system.
The shift to renewable and low carbon energy is just one part of a broader energy transition happening in the UK that will see clean energy sources replace fossil fuels in heating, transportation and industrial processes.
Today, solar and wind projects are not only unsubsidised but able to generate electricity at half the cost of an equivalent gas or coal fired power station.
In 2012, just 10% of UK electricity came from renewable sources, Fast forward to 2022 and more than a third of the UK’s electricity came from green and renewable sources. With nuclear power included, over half of UK electricity that year was from clean, low carbon sources.
The latest UK Government Energy Strategy – Powering Up Britain – seeks to accelerate the deployment of renewable energy projects in the UK as the backbone of a future energy system that promises greater energy affordability and energy security while also contributing to tackling climate change.
In 2022, half of our electricity came from low carbon sources
We have made significant progress with cleaning up our electricity grid, almost entirely replacing coal powered electricity generation in the process, but reducing our reliance on gas is an altogether harder challenge.
Renewable energy is weather dependent, making the job of balancing supply and demand much harder than it was when coal and gas fired power stations could be turned on, off, up and demand to exactly match demand.
The existing UK electricity network needs upgrading to support the deployment of renewable, low carbon energy and reach the goal of a net zero UK electricity supply by 2035. Our battery energy storage projects will provide the network balancing currently delivered by gas fired power stations.
But, delivering a 100% low carbon electricity grid requires network upgrades
How Battery Energy Storage Solves the Challenge of Balancing Supply and Demand in a Renewables Based Energy System
While much progress has been made with decarbonising our electricity supply, oil and gas is still the primary energy source for UK transportation and heating. Looking at UK energy consumption as a whole in 2021, 80% was provided by gas, oil and coal. While energy usage was responsible for 73% of all UK carbon emissions.
Decarbonising heat and transportation is much harder than electricity, not least because we’re talking about 41 million vehicles and 29 million homes rather than hundreds of power stations. But there are promising signs.
In 2023, there are more than 760,000 electric vehicles on the road in the UK and 380,000 households have installed an electric heat pump for heating and hot water. Every major car manufacturer is building electric vehicles and almost all of the major gas boiler manufacturers are manufacturing heat pumps.
And we need to decarbonise transport and heating as well
Not everything will be electrified. Hydrogen will play in role in decarbonising industrial processes. The aviation industry is banking on bio fuels – produced from vegetables not oil – to reach net zero. We will continue to burn gas with carbon emissions capture.
But much of the 80% of total UK energy consumption currently provided by fossil fuels will need to be met by clean electricity from renewable sources.
Predictions are that electricity consumption will increase by 100% to reach net zero by 2050. It’s why the UK Government goals is targeting a five fold increase in solar generation by 2035 and doubling wind generation by 2030.
