With fast growth of civilization there is also an ever mounting need for energy. Energy may be in the form of fuels or electricity. Petrol is a liquid fuel which is used widely nowadays. But this kind of fuels is likely to be exhausted at the rate man is using it recently.
To meet the challenge, various methods have been suggested. One is to minimize the man’s demand in using the energy. Non-essential consumption should be minimized. During certain days of the year, people all over the world turn off the electricity for 1 hour to save the energy. Modern gadgets consuming energy should only be used when they are absolutely necessary.
Energy conservation is possible through modernization of plant and equipment. People should replace the obsolete equipment by the modern ones.
Energy can be saved on transport by the following methods. People should commute by the rail rather than by cars and vans. The transport must be improved with a view to sparing the energy. Cities must be planned in such a way that the commuting distance from this place to others is minimized.
In industry, many things could be done to reduce waste of energy or to economize energy. The machine maintenance needs to be tightened; heater must be utilized properly. When systems are streamlined, economy in fuel is obvious. Instead of using materials requiring higher energy, those which require lower energy should be used.
We hope man with his ever rising urge for existence will cope up with this urgent problem and find alternatives.

There are some ways to have a good health in our life. First of all, we should have a reasonable diet. For example, we should eat more nutrition food instead of smoking or using alcoholic drinks. It is very important because what we eat highly affects our health. Besides, we can do exercise every morning such as: walking, jogging, riding bicycle and so on to keep fit. That helps us to have a well-proportioned body and always in good spirit. Finally, sleeping is also very important so we must sleep enough. If we sleep enough we will be high-spirited.

Health is important with all people in the world. People say that "Health is all". Health is wealth and we must agree that good health gives us to control our own lives. If you sick, you won't be able to do any work at all. Good health helps us have a complete happiness. Health is as important as life.
There are many to keep us healthy. First, we should do exercise everyday. We can walk on the street, do aerobics and so on. Second, we should go to the hospital to get a general check-up so that we can have information about our health. Third, we should have a health insurance too.

Around 2030 we will see commercialization of the first friction-free no-moving-parts flying vehicles which will be considered by many to be the ultimate freedom machine. Much like the transition from analog to digital in the world of information technology, the study of traditional mechanics and traditional aerodynamics will be replaced with a new physics governing vehicular movement.
Even today, flying cars are very much on the radar screen to become a next generation automotive technology. They will begin with a more convenient version of today’s airplanes and eventually converting over to the frictionless cars.

I think traffic education will be a great help. My father is a pretty safe driver, and he reads under traffic rules and practices best. When I often ask how he knows it, he looks at me and says: "If you want to join the traffic, you have to understand these things." The other problems I see with drivers today are distraction, distracted driving and not being aware of the surroundings. I think those people need to focus more so that there is no traffic accident. Moreover, they should learn about transport education
