What is Green Energy?

Clean or ‘Green’ Energy is produced with little-to-no environmental impact and doesn’t dispense greenhouse gases into the air that contribute to global warming in the same way that fossil fuels do. It is generated from natural and renewable resources that can be replenished and is a particularly appealing concept to many people because, unlike fossil fuels, such as coal and oil, renewable energy sources will not run out.

To meet this demand, many energy suppliers now offer green energy tariffs that offer some level of its energy produced from renewable sources.

What Types of Green Energy are there?

All types of green energy provide reliable energy and protect the environment. Green energy's varied forms mean more locations across the planet have the potential to harvest this renewable energy than ever before, meaning more energy can be collected right here in the UK

Wind energy is generated through the movement of air. It is captured by wind turbines that produce electricity using the kinetic energy created by air in motion.

Geothermal energy is produced using the heat that comes from the sub-surface of the earth. It is contained in the rocks and fluids beneath the earth’s crust and can be found as far down to the earth’s hot molten rock, magma. To produce power from geothermal energy, wells are dug deep underground to access steam and hot water, which can then be used to drive turbines connected to electricity generators.

Hydroelectric energy is generated using the motion of water. It is generated using flowing water to spin a turbine which turns a shaft that’s connected to an electric generator.

Solar energy is generated by the sun. It is captured through solar panels that convert the sun’s rays into usable electricity. Solar energy is also commonly used produce thermal energy to heat indoor spaces or fluids.

How do Green Energy Tariffs Work?

How do Green Energy Tariffs Work?

Once signed up to a green energy tariff you still get your electricity from the National Grid in the same way as any other customer. Electricity is generated from a range of sources, some of which are renewable and some of which are not, and is then fid in to the National Grid and then supplied to your home.

What happens is your supplier will match some, or all of, the electricity you use by buying energy produced from renewable energy generators. That's where the renewable energy that comes from wind, geo-thermal, hydro and solar fits in to the equation. The amount of green energy they buy depends on their level of commitment in the tariff.

This all means that the more households signed up to green energy tariffs thera are, the more renewable energy is fed into the National Grid.

How Green are Green Energy Tariffs?

Switching to a green tariff doesn’t automatically mean all of the electricity produced comes from renewable sources. Providers will produce some energy from fossil fuels, some from renewable sources and will buy some from renewable energy generators.

The mix of this energy production varies from provider to provider. Energy providers are required to publish details of what percentage of the electricity they generate comes from renewable sources and what percentage comes from other sources such as coal, gas and nuclear power, this is known as their 'fuel mix’.

Certain providers will have a higher percentage of renewable source in their energy mix than others.

Why Choose Green Energy?

Traditionally sourced energy comes from fossil fuels that release carbon dioxide into the atmosphere, contributing to the ever worsening global warming crisis. With climate change becoming increasingly important to our society, going green with your home energy tariff can help the environment.

Do Green Energy Tariffs Cost More?

Do Green Energy Tariffs Cost More?

When green energy tariffs were first launched, they were much pricier than standard, non-green tariffs. However, these days, costs have come down considerably and the price difference between green and non-green tariffs is much smaller. As the demand for green energy continues to grow, the price continues to drop. In fact, more than half of the 355 tariffs on sale in June 2019 claimed renewable electricity credentials. This compares to only 9% three years previously. Britain is currently generating more power from clean energy than from fossil fuels for the first time in history.
