Here at Love Energy Savings we’re passionate about helping our customers save money on their energy bills. But for many price isn’t the only priority.
When looking to switch suppliers, more and more customers are also interested in finding out which sources suppliers get their energy from – whether it’s from renewable, nuclear, coal, natural gas or another source. Or to put it another way: how clean the energy is. And it isn’t just homeowners. Businesses are also taking this into consideration when selecting a supplier.
In fact, we recently carried out a survey of 1,001 consumers to gauge opinion on clean energy, whether businesses have a responsibility to use it, and where they stand on how this affects their decisions when picking energy suppliers:
- 40% of respondents said they believe businesses should use renewable energy
- 33% said they would pay more for renewable energy
While not a majority, these consumers represent over a third of the market – and increasingly energy suppliers are putting environmentally friendly energy at the centre of their businesses.
Where does our energy come from?
Since the introduction of the 2005 Electricity (Fuel Mix Disclosure) Regulations, energy suppliers have been obliged to disclose the sources of their energy – their fuel mix. Each supplier has a different combination, made of:
- Renewables - energy that comes from sustainable sources, including hydro, wind and solar power, biomass and landfill gas
- Natural gas
- And other sources, which include non-biodegradable wastes, oil, coke oven gas, blast furnace gas, and waste products from chemical processes
How clean is the energy from the main energy suppliers?
Below you can find a breakdown of all the energy sources of each of the five biggest energy suppliers in the UK today.
British Gas, known as Scottish Gas in Scotland, is the UK’s largest energy supplier and owned by the Centrica Group, which funds gas and oil exploration in the UK, Europe and North America.
43% of the energy it supplies comes from renewable sources. Nuclear and natural gas accounting for 11% and 37% respectively, with 9% coming from coal and other sources.
France-based supplier EDF supplies around 5 million customers in the UK and has a strong focus on low-carbon electricity, energy production and nuclear investment. EDF has invested heavily in nuclear power since acquiring British Energy in 2009.
EDF’s investment in nuclear energy is clear: 72% of the energy it supplies comes from nuclear sources. The remainder is split between coal (5.2%), renewables (11.7%), natural gas (10.8%) and other sources.
E.ON was born from the merger between German industrial groups VEBA and VIAG in 2000, and in 2007 the company also took over Powergen to become a big player in the industry.
25.2% of E.ON’s energy comes from renewable sources. Natural gas provides 49.5%, coal 7.3% and nuclear 14.9%. The remaining 3.1% comes from other sources.
Big renewable energy supporters, Scottish Power became one of the UK’s largest suppliers in 2007 when they formed part of the Spanish energy giant Iberdrola group.
Natural gas (52%) and renewables (30%) are the main sources of Scottish Power’s energy. 11% comes from nuclear, with coal (5%) and other sources (2%) making up the rest.
The best known of the big six suppliers for their support of renewable energy, SSE are currently the second-biggest supplier of natural gas and electricity in the UK.
SSE gets 67% of its energy from gas, bolstered by a fair amount of renewables (23%). The rest comes from nuclear (4%), coal (4%) and other sources.
