ABSTRACT
Feed-in tariff – A UK government initiative that provides a financial incentive for users of low-carbon heating installations. Renewable energy is effectively free fuel, but remarkably few of these installations exist in the UK. Biogas – composed mainly of methane and carbon dioxide with minor traces of other gases. The energy potential in differing water levels has been exploited for centuries through water-mills and subsequently hydroelectric power. The power potential of water trapped within a lagoon is achieved by a difference in water level between open sea and that within a separating barrier or breakwater. Air pressure built up by the wave oscillations is used to propel an air turbine/electricity generator. Micro-combined Heat and Power (CHP) or microgeneration – an electricity generator at the point of use, independent of a mains grid supply of electricity, combined with a water heater.
