What’s in this guide?
Did you know that depending on your energy supplier, your energy could be coming from a different place?
Although most energy suppliers use a combination of fossil fuels such as gas and coal, some purchase their electricity from renewable generators.
That means it’s better for the planet, and sometimes better for your wallet.
Let’s take a look at fuel mixes, including what it is, which suppliers have what kind of fuel mix and the national average.
Read on and find out more.
What is a fuel mix?
A fuel mix refers to the blend of fuel that energy suppliers use to supply your energy. For instance, see the table below for Octopus Energy’s fuel mix and the comparison to the UK average.
Since 2005, it has been a legal requirement for your energy company to tell you what their fuel mix is so that you can make an educated decision about your energy.
This is particularly important if you care about having green energy or investing in renewable energy generation.
You can often find your energy suppliers fuel mix on their website. Usually under a tab or on the front page.
In each instance, you can compare it to the UK average.
This tells you how your energy company matches up to the UK average, which typically consists of approximately 24% renewable energy, 23% nuclear energy and 17% coal.
Below you can see the fuel mix for Octopus Energy, which was awarded Which? Recommended Provider in 2018.
Although they do offer a 100% green energy option, their fuel often consists of this mix:
|CO2 emissions||13 g/kWh||290 g/kWh|
|High-level radioactive waste||0.00004 g/kWh||0.0017 g/kWh|
So why is this so important? Let’s find out.
Why is it important?
Knowing your fuel mix is essential because it can help you understand the impact that your energy makes.
For instance, a good example is that if you use natural gas, you are paying for a natural gas-fired plant to produce your electricity. This is far more environmentally friendly than using coal for the same purpose.
As you can imagine, the higher your supplier’s renewable energy percentage, the greener your energy is.
Renewable energy comes from sources such as solar power, hydro, wind power or biomass.
The actual electricity you get won’t be different from anyone else, you will still get a steady and reliable stream that powers your home perfectly.
The only real difference is where your money is going.
Plus, when choosing green energy, you can rest easy that you’re helping to develop the UK’s switch to renewables.
