Pledge 1.

I will switch to a 100% renewable energy supplier. 

Why should I make the change?

At the moment, most homes in Scotland are kept warm by burning oil or gas to heat water for radiators, which releases the greenhouse gases that are driving the climate emergency. In fact, around 23% of Scotland’s greenhouse gas emissions comes from our homes and workplaces (1).

Switching to a 100% renewable energy tariff is a relatively quick first step to making your home more climate friendly. It takes a little bit of thought, but once it’s done, it’s done, and you can rest a little easier knowing that no fossil fuels were burnt to power your home.


I will switch to a 100% renewable energy tariff

We are all likely to be using some sustainably generated electricity no matter what tariff we are on, but switching to a specifically green tariff sends a message to suppliers that there is demand and that customers want to see a shift away from fossils fuels. The growing number of green tariffs shows that the suppliers are listening, so the switch to a renewable supplier is a valuable one, no matter which company you choose.

A green tariff means that some or all of the electricity you buy is ‘matched’ by purchases of renewable energy that your energy supplier makes on your behalf. Energy purchased on a green tariff comes from a variety of sources such as windfarms and hydroelectric schemes, with some offering a nuclear-free option. Some tariffs will be ‘100% renewable’, others will offer a percentage of the total. Your supplier will let you know how your energy is being produced and also what percentage of your supply is renewable.

Switching to the greenest tariffs means you are supporting the renewables industry, as the most sustainable suppliers purchase energy directly from the generating company. The best suppliers will be transparent about where they buy their energy from and will list this on their website.

The Energy Saving Trust have picked their top 3 renewables suppliers, who all clearly list the sources of their energy on their websites (as of Feb 2020).

Beware of greenwash

Some green tariffs are not all they are cracked up to be. Some claim to be 100 % renewable, but what the company is actually doing is buying up excess REGO certificates. These certificates are issued to renewable energy producers for each megawatt hour of renewable energy generated and are sold to non-renewable energy generators to create “green tariffs”. These certificates are cheaply available from times of excess production across the EU and these tariffs do little to encourage the generation of renewable energy in the UK. Often companies will divert their REGO certificate to their “green tariff”, away from their regular ones, meaning that while their renewable tariff looks clean, their non-renewable tariffs become dirtier. Make sure to read the small print of any tariff to see what type of “renewable” energy you are being offered.
