Microgenerators

As of 2000, it also looks as though more and more electric utilities are becoming interested in fuel cell stacks as local microgenerators to top up power from large power stations, without the need for long-distance transmission of electricity and its attendant expense and power losses. 

Among several investigated applications, an interesting one is the development of devices for the microgeneration of power based on a combustion process [35]. 

The simplest way to use renewable energy at home is to switch to a green electricity provider, but if you want to take your green commitment further and the idea of being energy independent appeals, become your own electricity supplier. Microgeneration schemes exist to harness the endless, natural supplies of power from the wind, sun, water, and earth. 

While some microgeneration schemes come close to fulfilling a household s energy needs, it is prudent to have a fail-back option. Most schemes work in tandem with an existing grid connection, which switches on in times of intermittent supply (as in wind and sun) or at peak usage times. This can also work in your favor—if your demand is low and you produce more electricity than you need, you could sell it back to a main grid. 

Microgeneration technologies include small wind turbines, solar photovoltaic (PV) systems, small-scale hydro and micro CHP (combined heat and power) systems,... 

Today, microgeneration systems generate relatively small amounts of energy at the site of a domestic or commercial building. However, it is estimated that by 2050, 30 to 40 per cent of the UK s electricity demand could be met by Installing microgeneration equipment to all types of buildings. 

Smart electricity meters are designed to be used in conjunction with microgenerators. 

Smart electricity meters are designed to be used in conjunction with microgenerators. Electricity generated by the consumer s microgenerator can be sold back to the energy supplier using the smart two-way meter. 

Small wind microgenerators can be used to make a useful contribution to a domestic property or a commercial building. They can be stand-alone and about the size of a tall street lamp. A12 m-high turbine costs about 24,000 and, with...
