Engineering - Research Paper Example It is essential that appliances which were introduced earlier (with usage of old technologies), prevail in energy consumption distribution; see Table above. For instance, energy consumption of the light bulbs, the kettle, and the electric oven takes over than 50% of total energy consumption. Simultaneously, usage of notebook, TV, and CD/DVD player takes less than 10% of total energy consumption in the household. Then, introducing of numerous appliances with high power inputs reflects in ecology due to necessity to make more electric power stations. It is essential that energy consumption can be reduced significantly without compromising human needs. There are several means to reduce adverse effects of usage of appliances with high energy consumption. First step is in limited usage of such appliances, e.g. switching-off non used light bulbs, unplugging seldom-used appliances and chargers for cell phone and other personal gadgets, setting computer to "sleep mode" or "hibernate mode", etc. Next step is more radical. This is replacement of appliances with high power inputs by equivalent appliances with less power inputs. For instance, replacement of old CRT monitor or TV by new TFT monitor or TV panel can significantly reduce energy consumption because these appliances are often used. ... However, these appliances need for enormous power supply and engineering support of appropriate infrastructure.

How to save energy in the household It is essential that energy consumption can be reduced significantly without compromising human needs. There are several means to reduce adverse effects of usage of appliances with high energy consumption. First step is in limited usage of such appliances, e.g. switching-off non used light bulbs, unplugging seldom-used appliances and chargers for cell phone and other personal gadgets, setting computer to "sleep mode" or "hibernate mode", etc. Next step is more radical. This is replacement of appliances with high power inputs by equivalent appliances with less power inputs. For instance, replacement of old CRT monitor or TV by new TFT monitor or TV panel can significantly reduce energy consumption because these appliances are often used. Replacement of standard light bulbs (100W) by low-energy fluorescent bulbs (less than 20W) is another example of such strategy. Many of new appliances use half the energy of those from decade ago. It is necessary to note that usually new appliances ar e more ergonomic and safe. Finally, there are
