Global warming induced by human activity is now well established. The key driver in increasing global temperatures is the burning of fossil fuels such as coal, oil, and natrural gas. In order to reduce our dependency on these materials and to improve the environment more and more businesse are switching to renewable sources or energy, such as wind, hydro and wave, and energy derived from waste and organic residues.  A key site for the Irish market is the Sustainable Energy Authority of Ireland, where you will find lots of explanatory information. One of the principal initiatives to consider is implementing Combined Heat and Power, CHP. Producing power or heat in a generator or boiler on its own is inefficient (~30%), whereas producing both together in the sense of capturing the waste heat as part of power generation increases efficiency into the 75-80% range with obvious benefits. A good explanation of this technology can be found at

A growing area of interest is anaerobic digestion of organic wastes and biomass, see UK Anaerobic Digestion and Biogas Association website access to wide-ranging information on this exciting area.
