Energy efficiency is a term that is often heard but it is a term that not a lot of thought goes into. Many people think the term relates to an appliance that uses less electricity, but energy efficiency means so much more than that. Energy efficiency is the effort made to achieve the goal of reducing the amount of energy that is used when providing a product or a service.
A simple example would be home insulation. Insulating a home means a building uses less heating and cooling energy to maintain a comfortable temperature in the home. The manufacturer of the insulation material is likely to be striving to save energy in the manufacturing process and may be using solar power to generate electricity for his offices or manufacturing plant. Taking this chain of energy events, it can be clearly seen that energy efficiency is applicable to more than the energy rating on a new refrigerator. For the manufacturer, he is saving on electrical costs, operating a green business model and supplying a product that has the same benefits for the customer.
Obviously, there are many different motivations for improving energy efficiency. By reducing the amount of energy used for a given process, cost savings may be able to be passed on to consumers. Reducing energy use is also important to reducing emissions. Statistics show that improved efficiency in buildings, transportation, and industrial processes could reduce the world’s energy needs by one third with the benefit of controlling greenhouse gases.
Energy efficiency cannot be mentioned without reference to renewable energy and both are key elements in any kind of sustainable energy policy. On a global scale this means some countries will be able to reduce the amount of energy imports from foreign countries and become more self sufficient in renewable energy methods, saving their own domestic energy resources
Keeping air conditioning well-maintained can help your system last for decades and along with some other useful energy saving actions, make the system as energy efficient as possible. A neglected air conditioning system loses around five percent efficiency each year by not being maintained. Filters and coils are both parts that require regular maintenance for air conditioning to operate effectively and efficiently. By keeping systems at peak performance, any costs spent on maintenance will be recovered by cheaper repair costs and electricity cost savings.
One of the most simple energy efficiency savings to be made with air conditioning is to set the thermostat a few degrees higher when the house is going to be empty for a while and automatically set it to return to optimum cooling temperature half an hour before the house is occupied again. Another saving of five to fifteen percent is made by keeping the air conditioning systems filters clean. Once a month the filters should be cleaned and replaced if necessary. Make sure no heat generating appliances like table lamps or televisions are located near the thermostat as this will artificially be telling the system the room is hotter than it is causing unnecessary energy usage.
