Our electricity cocktail

Our company fuel mix is as follows:

We have simple tariffs that have a positive impact. Let us tell you a little more about them:

In our Tap and Still tariff, we use something called 'combined heat and power' (CHP to its friends). In a nutshell, power plants give off a lot of heat when they make electricity. When this heat would otherwise go to waste, green energy uk's suppliers harness it and put it to good use.

We get CHP from some pretty quirky sources, too. Sign up to Still and tomatoes and hot water pipes could help to power your house!

And you can't get greener than our Sparkling tariff. Using the power of falling water, the sun, the wind, and organic waste material, we provide energy that is 100% sustainable.

Not only is this tariff sustainable, but it helps to clean up and make use of waste products. Some of our generators even use pig poo, skip waste and used chip fat to make electricity!

What about gas?

Our gas is green too! 100%

Gas like electricity is a homogenous product when delivered to consumers but the gas we put into the grid is not. Green gas, or biogas, is sourced from processes like Anaerobic Digestion (AD), where waste that would otherwise leak methane into the atmosphere (methane is 20 times more potent than CO2), is processed into biogas to be used as fuel. All our gas will come with a Green Gas certificate under this independent scheme http://www.greengas.org.uk.


Gas

How is it generated?

It’s generated in weird and wonderful ways. It’s fun to sell; that makes us happy.

Hydro

Harnessing the British weather.

Hydro-electricity means taking the force of free-falling water and converting it into power. Some of our energy comes from small hydro-electric schemes in Scotland, Dorset and Cornwall.

Anaerobic digestion

Finally something useful from what comes out of the back end of a pig.

Anaerobic digestion – a process where microorganisms break down organic material in the absence of any oxygen to produce a methane and carbon dioxide-rich biogas. This can be burnt to produce energy, with none of the harmful effects of fossil fuels. And what's more, the nutrient-rich solids left after digestion can be handily used as a fertiliser!

CHP

CHP what?

Combined heat and power (CHP) is the simultaneous generation of heat and power (usually electricity) in a single process. In a standard power plant a huge amount of energy is lost as waste heat. CHP plants harness this 'waste' heat for a useful purpose (heating a block of flats for example). As a result CHP plants can be up to 95% efficient, almost twice as efficient as gas or coal fired power stations. The CHP process is therefore both green and historically Climate Change Levy exempt.

Aberdeen Heat and Power

Solar

Energy from 93 million miles away.

A solar cell (or a 'photovoltaic cell' to you scientists out there) takes the light from the sun and converts it into power. 'Solar thermal systems' take heat from the sun and use it to heat water in our homes.

Solar

Wind

Love it or hate it we don’t use much of it.

Does what it says on the tin. Our suppliers use the force of the wind to drive turbines, which in turn make electricity.

RES Group

Biomass

Plants to you and me.

Biomass is produced from organic material – that's wood, plants and animal waste to you and me. We get this either directly from plants, or from waste products from industry, agriculture or your very own home!

Biomass

Our electricity generators

Safe energy from sound sources.

Gask Farm

Gask Farm

The folks down at Gask farm have finally solved the problem of what to do with their pig manure. Turn it in to electricity! Pig slurry is fed into an anaerobic digester and the gas released is captured and burnt to generate electricity. The fertiliser produced as a by-product is used to feed the crops which are then fed to the pigs the following year. A real circle of life!

Aberdeen Heat and Power

Seaton Energy

At a housing development in Aberdeenshire a Combined Heat and Power (CHP) unit is supplying heat and hot water to up to 500 flats, to a sports changing facility, and to the Council owned ballroom, leisure centre and ice-rink. The excess electricity produced is bought by us and supplied to customers on our Still tariff.

Jake's Nursery Tomato Farm

Jakes Nursery

Jakes Nursery is a tomato farm in Sidlesham in Chichester. Since 2007 Jakes have been supplying Green Energy UK with electricity created solely as a by-product of their tomato growing process!

Faichemard Farm

Faichemard Farm

Highlands farmer Duncan Grant is taking advantage of a river running through his family farm by creating electricity from it. He has installed a micro hydro-generator and is selling the electricity to us.

Amazing what comes from the
back end of a pig (or cow)
