Good Energy supports homes and businesses generate, use and share renewable energy.  

When we use the term ‘greener energy’, we mean energy generated in a way that has a lower environmental impact than energy generated from fossil fuels such as coal, oil and gas. This includes renewable electricity and carbon-neutral gas tariffs; products that enable people to use more renewable electricity at home such as heat pumps, solar panels and batteries; and products that support the transition to electrified transport such as electric vehicle charge points.   

We offer 100% renewable electricity and greener gas tariffs 

100% renewable electricity 

When you switch to Good Energy, we match all the electricity you use at home with electricity generated from renewable sources. We buy electricity directly from over 2,000 independent renewable generators across Britain.  

This means that, while your home will still get its electricity through the national grid, the volume of electricity you ‘take out’ is balanced by Good Energy generators feeding in renewable electricity.  

Electricity from renewable sources is greener than electricity from fossil fuels such as coal, oil and gas because it produces zero carbon emissions as it is generated. Burning fossil fuels is responsible for nearly 90% of global carbon emissions, making it the largest contributor to global heating and the climate crisis. The UN’s International Panel on Climate Change (IPCC) makes it clear that mitigating climate change requires “transitioning from fossil fuels to very low or zero carbon energy sources, such as renewables”.

Carbon neutral gas 

Our Greener Gas tariff is made up of 10% renewable biogas, generated in Britain from breaking down organic matter via anaerobic digestion.  

We offset the total emissions resulting from the gas used by our customers by buying carbon credits in Gold Standard offsetting projects. These projects directly support the growth of renewable energy, for example by replacing burning solid fuels such as wood and coal with biogas generation.  

Independently accredited tariffs 

Our electricity and greener gas tariffs are recommended for being green by independent experts. All our tariffs are Uswitch Green Tariff Gold Standard, and we have been a top-rated Which? Eco Provider for Energy for three years in a row. Good Energy tariffs are also recommended for by Friends of the Earth.

We install heat pumps, which cut your carbon footprint by around 65% compared to gas or oil boilers

Switching from a boiler to an air source heat pump is one of the biggest things you can do to reduce your home’s carbon footprint. For UK properties, it results in an average reduction in carbon emissions of around 65%. 

The government’s latest official carbon conversion factors show that the UK electricity grid’s carbon intensity is similar to gas consumption on a grams of CO2 per kilowatt hour basis. But because heat pumps provide heating over three times more efficiently than a gas boiler, they consume far less energy to provide the same amount of heating – resulting in a smaller carbon footprint. 

Heat pumps with a higher efficiency rating will be even lower carbon. The minimum level of efficiency for a heat pump installation to be eligible for the Boiler Upgrade Scheme grant is 2.8, as set out in government policy standards

Data collected over 12 months from heat pumps installed by Good Energy shows our installations reach an average efficiency of 3.4

We install solar panels & batteries, which enable you to get more of your electricity from renewable sources 

Installing solar panels on your property means you are directly generating and using renewable electricity. This not only reduces the amount of electricity you need to draw from the national grid, but solar power that doesn’t get used within your property or stored within a battery will feed into the energy grid, increasing the volume of electricity generated from renewable sources.  

Manufacturing, transporting and installing solar panels generates carbon emissions. However, as solar panels save around 900kg in carbon emissions each year compared to electricity from the national grid, this carbon is paid back in around 1.6 years. Well-maintained solar panels will last 25-30 years or more, resulting in a net carbon saving compared to using electricity from the grid. 

The Centre for Alternative Technology estimates that a home battery would need to be charged using renewable electricity (for example, from solar panels) and used to replace electricity predominately generated using gas around 200 times to pay back the carbon emissions resulting from the manufacturing process. Depending on how often this happens, the carbon payback period for a home battery could be 1-2 years. 

We install electric vehicle charge points, to support the transition to greener transport 

In comparison to traditional cars, which burn petrol or diesel and generate carbon dioxide emissions every time they are driven, electric vehicles produce no direct emissions. Research by Carbon Brief has found that the average electric vehicle being driven in the UK will pay back the carbon emissions generated from its manufacture within 2 years.  

What’s more, the research found that “over the full vehicle lifecycle, carbon dioxide (CO2) emissions from an EV are around three times lower than an average petrol car”. 

Across electricity, heating and transport, the tariffs and technology installed by Good Energy saves carbon emissions compared to using energy from burning fossil fuels. This is why we can provide you with greener energy.
