As you know, sources of energy like solar energy, wind energy,.. are very important. People use them for many things:cooking, heating,ect...But, almost the sources of energy have the disadvantages and advantages. There are two kinds of energy:non-renewable and renewable energy. Non-renewable is very popular in many countries. They are abundant, available and easy to use. However, they won't last forever and they're harmful for the environment. And, people will use renewable energy to solve the problems of non-renewable energy. Renewable sources of energy are forever and they're clean and safe, too. Nevertheless, they have some problems, too. For example, nuclear is clean but it's dangerous to use. Wind power has many advantages but it isn't available,... On the other hand, there are some sources of energy don't have some serious problems like solar energy. It's the reason why people use solar energy in the future. So, what should we do to save energy? We should use them properly and use them less. We should use less cars or motorbike, too. It also have the enviroment. Energy is very important, we should protect them for our life in the future.

The energy generated from natural sources such as the sun， wind， rain， and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover， using renewable energy can reduce your electricity bills. Unfortunately， solar energy can be only used during the daytime but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth’s surface to the top and can create environmental changes.

We can save energy by doing some following tips. First of all, we should use electricity more efficiently and reduce our electricity bill. We need to turn off the TV when we are not watching, turn off all the lights before going to bed. Besides, we should not leave the fridge door open in a long time due to wasting of electricity. Moreover, we should save water by taking showers instead of baths or turning off the water when you don not use it. The next tip is reducing the use of fossil fuels like gas, coal, and oil. It is not only saving energy but also protect our environment. To do this, we can use public transport and avoid using car or motorbike for short trip. All in all, because our energy is limited we need to reserve it for the future generations.
