Types of green energy
A solar cell or photovoltaic cell more precisely is the sunlight and converts it into energy. Solar thermal systems take the heat of the sun and use that to heat water for households. In the UK due to our unpredictable weather photovoltaic power is most commonly used.
Biomass is produced from organic matter either directly from plants or indirectly from industrial, commercial, domestic or agricultural.
- Wood biomass includes forest products, wood waste and energy crops like elephant grass and fast growing trees like willow. We also buy energy created from burning wood waste.
- Non-wood biomass includes animal waste and biodegradable food products such as vegetable oil.
We buy electricity from small-scale hydroelectric systems currently based in Scotland, Cambridge and the Peak District. hydroelectric power take water in free fall and turn this energy into electricity. CHP Cleaner
Combined heat and power (CHP) is the simultaneous generation of heat and power (usually electricity) in a single process. In a standard power plant an enormous amount of energy is lost as waste heat. ‘Waste’ cogeneration plants harness this heat to a useful purpose (heating of a residential building, for example). As a result of cogeneration plants can be up to 95% efficiency, nearly twice as efficient as gas or coal power plants. The cogeneration process is therefore green and climate change levy exempt.
Most of the cogeneration we buy comes from two very different sources
1. Industrials Electricity is generated by the producers of tomatoes and peppers. They burn gas to heat their homes to produce green or carbon dioxide to enrich the atmosphere actually growing plants. This green electricity produced is a useful product that nurseries can not be used to sell back to us in the UK green energy which is fed into the network so that others can use.
2. Residential-A cogeneration plant and heating to a network of hot water pipes with insulation that transport heat around a building often public or private sector flats. Meanwhile, the electricity generated is used in common areas or exported to the grid.
Anaerobic digestion is a renewable energy source because the process produces a methane and carbon dioxide rich bio gas suitable for energy production helping replace fossil fuels. In addition, nutrient-rich solids, left after digestion can be used as fertilizer.
making small scale wind energy and uses wind to spin a turbine that generates electricity.
