Energy sources Our energy needs.For people live on our planet, we need energy.We need energy for heat, for light and for transportation.When its cold, we need energy for heat; when its dark, we need energy for light.When we want to travel, we need energy for transportation. For example, to run our cars, we burn gasoline, which comes from oil.We also need energy to run our factories. Here are some of the ways we get energy.Fossil fuels include coal, oil, and natural gases. Fossil fuels are important sources of energy.We burn fossil fuels to generate electricity.Another source of energy is hydroelectricity power. Hydroelectric power comes from the energy of falling water.The energy of falling water is converted into electricityNuclear power is another way to get energy. Heat from nuclear reaction is converted into electricity. There are also other ways to get energy.Solar cells can converted into sunlight directly into electricityMany people that the use of solar energy will increase, because they are safe for the environment, however, solar energy is still expensive and underdeveloped.Wind power is also a safe source of energy; however, it is only useful in the area where there is a lot of wind.Like solar energy, the use of wind power is still quite limited.Questions:When its cold, what do we need energy for?Are coal and oil both fossil fuels?In your country, do many homes use solar energy? Whats a good way to get energy in a area where there is a lots of sunlight? Converting sunlight into heat and electricity requires sunlight.What about the future?One of the main problems we now face is how to reduce the use of fossil fuels.There are several reasons why this is important.One reason is that the supply of fossil fuels is running out.Fossil fuels are not renewable. As the supply decreases, the price will increase, there may even be war.There is also the problem of transport.Large oil tanks transport oil across the oceans.Sometimes there are accidents and large amounts of oil spilling into the oceans.In the past few years, there have been several accidents.These accidents have caused the death of many fish, birds and other wildlife.Another problem is air pollution.When we burn fossil fuels, waste gases such as carbon dioxide are produced.The waste gases enter our atmosphere and cause pollution, which damages our environment.For example, air pollution causes acid rain and acid rain is killing many of our forests.There is also the problem of global warming.When a large amount of carbon gases are in the atmosphere, our world begins to heat up.If the temperature rises, the polar ice cap will begin to melt and oceans will rise.Plants and trees help reduce global warming, because they convert carbon dioxide into oxygen.If there are more plants, then the rate of global warming is reduced.However, many of our great forests are being cut down or burned. Our forests are also being killed by acid rain.So, as you can see, it is important for us to move away from fossil fuels as soon as possible.Nuclear energy also has problems.One problem is safety, nuclear reactors are not completely safe.There is always some risk of accident.In some cases, radiation has escaped into atmosphere and into water supplies.Another serious problem is the problem of nuclear waste.The radiation from nuclear waste products is very dangerous.If it gets into the environment, it can cause serious health problems and even death.How about hydro-electro power, Can it help us move away
