Often the focus is on alternative Energy sources and while it is commendable to consider and take such challenges as solar, wind of the mixtures that is passive up. Of just as crucial importance is the efficacy of the installation. With the aforementioned the whole of Life energy expenditure must be considered. Lots of the energy options have an energy expenditure when end of life costs and costs are payable. As the whole of life cost is factored in, often the energy saving disappears. This is not to imply that we should not consider energy types but we need to make sure that we are not deceiving ourselves when we doing comparisons to conventional energy sources like gas, coal or fossil fuel.
With these energy sources that are conventional for the technology we can see the advantages, although we are well versed in the whole of life cost because we have used them for so long. It is like recalling our childhood we have the ability to concentrate on the good bits and the bad bits fade away into the land a bit. Energy efficiency is all about minimizing Losses or using the ‘lost’ energy for some function that is useful. A very simple example is that of a gas turbine industry energy efficiency courses Singapore, in what is called easy cycle form the exhaust temperature is in the sequence of 540 degrees Celsius. This warmth is wasted and goes up into the air.
With the Arrival of a cycle Arrangement, using a HRSG (Heat Recovery Steam Generator) this waste energy can be used to drive a steam turbine driven generator and average produce half as much power again as the initial Gas turbine generator setup. There is the capital cost of the combined cycle arrangement. Typically a simple cycle unit is in the order of 25-30% efficiency whereas a combined cycle structure is around the 60-65% efficiency. If needed the energy may be used in industry for process steam. We need to make sure that we are Read and up to date and energy efficiency if we are to make energy utilization.
