Our renewable mix, from the ground up

By now you’re probably already aware that all our electricity is 100% renewable, as standard, whichever tariff you choose.

Our renewable electricity is certified by Renewable Energy Guarantees of Origin (REGOs), which means that all of the electricity you buy from us is matched with the equivalent amount of units from 100% renewable sources in the UK.

There are multiple renewable sources that contribute to our fuel mix, but how do they work?


As much as we sometimes moan about the weather, at least we know the wind isn’t going to run out in the UK anytime soon; this makes it a great renewable source.

How does it work?

The blades on a wind turbine spin as the wind flows past them. They’re connected to a generator and, as they move, this generator converts the energy into electricity which can be fed into the national grid via a transformer.

Solar panels use photovoltaic cells to harness the power of the sun and create electricity. As if we needed another reason to love the sunshine.

How does it work?

Solar panels are made of two sheets of silicon placed on top of each, with a rather slim gap between them. One sheet is positively charged, the other negatively charged; this causes a tension between the sheets.

When the sunlight hits the top of the panels, the tension in the sheets causes electrons to be dragged in one direction to create direct current (or DC) electricity.

We can use it in our homes by passing it through an inverter and turning it into alternating current (AC) electricity.

This video from SciToons goes into more detail and sums it up pretty well.


Bioenergy is made from anything that is derived from organic matter, including wood, crops, and waste products.

How does it work?

As mentioned above, different types of materials can be used for bioenergy, varying from wood to crops, however the principle behind producing energy from them remains the same; the matter is burnt or broken down to produces gas or heat, which can then be used to power a turbine to produce electricity.

Renewable energy sources are just the start

Small changes can eventually add up to make a big difference. That’s why as well as offering renewable electricity, we make it easy to more efficiently manage household energy by offering smart home technology. We’re also offering exclusive electric vehicle home charging (powered by renewable electricity) to help aid the transition to electric cars.

We’re also contributing to nature-based carbon offset programs. These projects protect existing natural forest ecosystems, which absorb and store carbon dioxide.

And so we can be sure that we're helping to make a difference, we’ll only contribute to projects that are certified to government or voluntary carbon credit standards. We’re working with two important projects in Cordillera Azul (Peru) and Katingan Mentaya (Indonesia).

These projects provide job opportunities for local communities, as well as helping to reduce CO2 emissions globally, which is good news for everyone, including us here in the UK.
