The use of electricity in England is indspensed with Demand for electricity in England during typical days in winter and summer is illustrated in the graph. The use of electricity in an average English home is shown in the pie chart. From the graph, it is generally obvious that the demand is in its maximum around 2100, and in its minimum around 4000, being almost constant between 1900 and 2100 in winter times. During summer times, on the other hand, the demand reaches its top point around 1300, and the bottom point around 900, being almost constant between 1550 and 2000. In Winter times, the curve gradually increases to reach 40000 units of electricity by 3 o'clock in the morning. This is followed by gradual decline to its lowest limit of 30000 units at 9 o'clock. A gradual rise is obvious again to reach a stationary level between 3 o'clock and 9 o'clock of about 40000 units again. Then, there is a sharp rise in the next hour to reach its maximum before collapsing again to a lower level by the end of the day. In summer time, the curve gradually decrease to reach its lower limit around 9 o'clock of a bit more than 10000 units. A gradual increase is noticed to reach its top of 20000 after which a stationary phase is obvious between 3 o'clock and 10 o'clock at night of about 15000 units. The pie chart, on the other hand, shows that 52.5% of the electricity is used for heating rooms and water. 15% is consumed for ovens, kettles and washing machines, 15% is used in lighting, TV and radio, and finally 5% is consumed in the use of vacuum cleaners, food mixtures and electric tools.

Happiness is very difficult to define, because it means so many different things to different people. While some people link happiness to wealth and material success, others think it lies in emotions and loving personal relationships. Yet others think that spiritual paths, rather than either the material world or relationships with people, are the only way to true happiness. Because people interpret happiness for themselves in so many different ways, it is difficult to give any definition that is true for everyone. However, if there are different kinds of happiness for different individuals then the first step in achieving it would be to have a degree of self-knowledge. A person needs to know who he or she is before being able to know what it is that makes him or her happy. Of course, factors such as loving relationships, good health, the skills to earn a living and a peaceful environment all contribute to our happiness too. But this does not mean that people without these conditions cannot be happy. Overall, I think an ability to keep clear perspectives in life is a more essential factor in achieving happiness. By that I mean an ability to have a clear sense of what is important in our lives (the welfare of our families, the quality of our relationships, making other people happy, etc.) and what is not (a problem at work, getting annoyed about trivial things, etc.). Like self-awareness, this is also very difficult to achieve, but I think these are the two factors that may be the most important for achieving happiness.
