Energy Consumption in My Household - Personal Statement Example

For instance, the energy consumption of the light bulbs, the kettle, and the electric oven takes over 50% of total energy consumption. Simultaneously, the usage of a notebook, TV, and CD/DVD player takes less than 10% of total energy consumption in the household. Then, introducing numerous appliances with high power inputs reflects in ecology due to the 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 the adverse effects of the usage of appliances with high energy consumption. The first step is in limited usage of such appliances, e.g. switching-off used light bulbs, unplugging seldom-used appliances and chargers for cell phones and other personal gadgets, setting the computer to "sleep mode" or "hibernate mode", etc. The next step is more radical. This is the replacement of appliances with high power inputs by equivalent appliances with fewer power inputs.

For instance, the replacement of the old CRT monitor or TV by a new TFT monitor or TV panel can significantly reduce energy consumption because these appliances are often used. However, these appliances need an enormous power supply and engineering support of appropriate infrastructure. It is essential that appliances which were introduced earlier (with the usage of old technologies) prevail in energy consumption distribution; see Table above. For instance, the energy consumption of the light bulbs, the kettle, and the electric oven takes over 50% of total energy consumption.

Simultaneously, the usage of a notebook, TV, and CD/DVD player takes less than 10% of total energy consumption in the household. Then, introducing numerous appliances with high power inputs reflects in ecology due to the necessity to make more electric power stations. 3. How to save energy in the householdIt is essential that energy consumption can be reduced significantly without compromising human needs. There are several means to reduce the adverse effects of the usage of appliances with high energy consumption.

The first step is in limited usage of such appliances, e.g. switching-off used light bulbs, unplugging seldom-used appliances and chargers for cell phones and other personal gadgets, setting the computer to "sleep mode" or "hibernate mode", etc. The next step is more radical. This is the replacement of appliances with high power inputs by equivalent appliances with fewer power inputs. For instance, the replacement of the old CRT monitor or TV by a 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 a strategy. Many new appliances use half the energy of those from a decade ago. It is necessary to note that usually, new appliances are more ergonomic and safe.
