Green energy suppliers

‘Green’ tariffs are increasingly popular with consumers. The Diocese encourages every parish to transfer to a green tariff for 100% renewable electricity. In some cases, ‘green gas’ may also be worth considering.

This is one of the first steps to save energy and carbon emissions advocated for churches and people in the Diocese – the others being to review your heating system and its settings, and to change the lightbulbs to low energy models, usually LEDs. Most of our churches have taken these steps already.

Introduction

One of the simplest steps we can take in contributing to the effort against climate change is to switch to a ‘green energy’ supplier.

Every supplier has to meet a minimum government standard; the cost of doing this is built into the tariff.

But this only goes part of the way. Some suppliers go further, with specific ‘green tariff’ options.

In the past these green options have come at a higher cost. That’s not necessarily so now. It is beginning to be possible to combine the cost benefit with an environmentally sensitive option.

100% renewable energy

However it’s best to switch to a company exclusively offering a supply of 100% renewable energy that it has itself generated or directly paid for.

Electricity

There is a limited choice of genuinely renewable electricity. Links to companies are at the foot of this page.

The alternative is to use the national Parish Buying scheme’s Green Energy Basket.

The national Energy Footprint Tool, part of Parish Annual Returns, deems these options (but only these options) as genuinely renewable, and therefore (near) net zero carbon for electricity.

However strictly speaking, even this renewable electricity is not all renewable, as the energy used in ‘transmission and distribution’ (ie within the national grid), is also accounted for by the Church of England, including in the Energy Footprint Tool. This energy loss may not be fully compensated by renewable energy purchased by your supplier.

Nonetheless we still term it ‘100% renewable’ to distinguish from tariffs which only offer a percentage of renewable energy, while correctly accounting for the non-renewable element in calculations and the annual results of the Energy Footprint Tool, reported by the Church of England.

Gas

Very few companies offer genuinely ‘green gas’. This means biomethane, refined from biofuel. See links below.

Other companies offset their gas through a variety of schemes. Purely from the point of view of your carbon footprint, it is better to buy genuinely green gas. This offers greater assurance for the customer.

However there are also other factors to consider, eg cost, and ethical sourcing. For example, some biomethane supplies may originate in factory farms and abattoirs. The time has yet to come when it is possible to discriminate on where your green gas comes from.

‘Green gas’, like renewable electricity, is also not actually 100% renewable. Its carbon emissions (CO2e) are about 75% less than natural gas. For calculation, we use CO2 conversion factors for biomethane published by the UK government, as we do for all other fuels.

How to switch

Nevertheless it is well worth switching, especially to renewable electricity. The Diocese encourages every parish to do so. Details are given below of companies listed by the Energy Footprint Tool.

Before taking a final decision on switching, you can call the Head of Environment and Sustainability to discuss the above advice and options for your church.
