Greener Future

McNulty are to change from the traditional method of electricity supply to the "green" energy source of Combined Heat and Power (CHP).

CHP id the simultaneous generation of heat and power, usually electricity, in a single process.  Combined with the centralised generation of electricity, when the waste heat produced from the generation process is generally discarded.

Traditionally, electricity has been supplied by burning non-renewable fuels such as oil, coal and gas.  As is regularly documented, using these fuels result in large amounts of Carbon Dioxide being released into the atmosphere, thus increasing the effects of global warming.  This is widely believed to be a fundamental cause of climate change.  Furthermore, these fuels are becoming increasingly scarce leading to price rises in a already unsettled global energy market.

"Green" electricity is energy produced either via renewable fuel sources (solar, wind, etc.) or by Combined Heat & Power (CHP) systems which offer a much more efficient method of electricity generation when compared to traditional power stations.  Typical efficiency figures are 30 - 45% for traditional power stations, as the heat produced is unharnessed and release as waste via cooling towers etc. because CHP systems make extensive use of heat produced during the electricity generation process, they can achieve overall efficiencies in excess of 70% at the point of use.

MOCL's 'green' energy is to be derived from a CHP scheme operated by SWALEC.
