100% renewable electricity

Why is renewable energy important?

A lot of the energy generated within the UK comes from fossil fuels such as oil, gas and coal. These generate greenhouse gases, pollute our air and negatively impact the environment, contributing to climate change.

Renewable energy, such as wind, water and solar are alternatives to fossil fuels. These green renewable energy sources are more sustainable, and provide substantial benefits for our climate, our health and our economy.

What does 100% electricity actually mean?

The ‘normal’ energy supplied to a customer’s home comes from the National Grid and is made up of electricity and gas (if you have both) produced from a variety of sources. We'll match 100% of the electricity you use on this tariff with the purchase of Renewable Energy Guarantee of Origin (REGOs).

Choosing a tariff with renewable electricity increases demand for renewables, which makes it more attractive for investors to invest in more renewable sites. So although it’s not possible to know whether the electricity that ends up in your home is from a renewable source – we can guarantee that every unit you use will be replaced on the network by a unit of renewably sourced electricity. Beyond this, there are currently no additional environmental benefits to this tariff.

What does additionality mean?

When green tariffs offer additional benefits to the environment, in addition to other legal obligations and schemes, this is called ‘additionality’. You may have seen tariffs such as donations to an environmental charity, planting trees, supporting community energy projects or building new renewables such as offshore wind. For Sainsbury’s Energy Fix & Reward tariffs we do not currently offer these sort of additional environmental benefits. 

What are Renewable Energy Guarantees of Origin (REGOs)?

Every unit of renewable electricity that we source comes with a Renewable Energy Guarantees of Origin (REGO) Certificate – they essentially provide proof that the electricity has been generated from a renewable source. OFGEM issue one REGO per megawatt hour (MWh) of electricity generated from eligible sources to renewable electricity generators. 

What is your approach to sustainability?

Sainsbury’s Energy is a partnership between Sainsbury’s and npower. Both companies are committed to pushing sustainability through their business activities.

From the little things such as making our tariffs paperless, through to wider initiatives run by our fellow group companies, we continue to look for ways to balance sustainable practices with cost effective energy.
