Biomass is produced from organic material, either from plants or indirectly from business, zommercial, domestic or rural products.

Biomass falls into two classes:

* Wood biomass includes forest products, waste wood and energy crops like elephant grass and quick-growing trees like willow. We also buy energy made from burning waste wood.
* Non-wood biomass means animal waste and biodegradable food products like plant oil. Hydro we buy electricity generated from small-scale hydro-electric schemes currently based in Cumbria, Cambridgeshire and the Top District.

Hydro
Electric power plants take the power from free falling water and turn this energy into electricity
Cleaner CHP
Mixed heat and power (CHP) is the concurrent generation of heat and power (sometimes electricity) in a single process.

CHP is a very effective way to use both fossil and replaceable fuels. The method is green and global warming Levy exempt.

Most of the CHP we buy comes from 2 completely different sources

1.Industrial- Electricity is created by growers of tomatoes and peppers. They burn gas to heat their green homes or to really produce CO2 to improve the growing atmosphere of the plants. This green electricity produced is a handy by product the nurseries can't use so sell back to us at green energy uk where it is fed into the grid for others to use.
2. Residential- A CHP plant supplies heating to a grid of insulated hot water pipes that carry heat around a building regularly public or non-public sector terraces. Meanwhile, the electricity generated is used in the communal areas or is exported to the power grid.

Anaerobic

Anaerobic is a green power source as the process produces a methane and CO2 rich biogas acceptable for power production helping replace carbon-based fuels. Also, the nutrient heavy solids left after digestion may be employed as fertilizer.

Wind

Little scale wind takes the energy in the wind and uses it to turn a turbine that creates electricity.
