In a fuel cell, the chemical energy within the fuel is converted directly into electricity (with by-products of heat and water) without any mechanical drive or generator. This can result in high electrical conversion efficiencies and low emissions. The fuel cell may eventually replace a conventional gas boiler in a central heating system and can generate electricity with a higher efficiency than central power plant and, being located in the home, any waste heat can be used by the household, rather than dumped into the atmosphere.

Energy efficiency is widely regarded as the most important first step in making the transition to a low carbon economy. Whilst renewable energy and other measures are also vital components, energy efficiency ensures that valuable energy - whether it be heating, cooling, or electricity - is not wasted. There are numerous energy efficiency technologies, from insulation materials to a plethora of more efficient electrical devices, and more energy efficient vehicles. Explore these pages to find energy efficiency solutions that are right for you. - Description added by: David Lockie
