There are many types of energy sources. In a world where the instability of both society and nature is increasing, the issue of energy is a hot issue of great concern. Fossil energy sources, which have been considered as the main source of energy, are gradually becoming scarce and are also the cause of many immobility and disputes between countries around the world. The following energy sources are available: Nuclear Energy, Compressed Natural Gas; Biomass energy; Geothermal energy. Meanwhile, as scientists predict, with the current rate of exploitation and use of fossil resources, within a few centuries our descendants will have to bear serious consequences. Since then, the need for alternative energy sources has become more and more urgent, and more and more alternative energy research projects have been started and developed. However, not 100% of them are suitable for future development.

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.

Hello everyone, today I'd like to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.

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.

Non-renewable energy is the energy taken from other sources that are available on earth.They are limited and will run out in the future. They can't be re-generated in a short time.Fossil fuels - natural gas, oil and coal - are examples of them. They are cheap and easy to use. However, when burnt, they release toxic gases in the air so they cause serious environmental changes such as global warming. And the important thing is that non-renewable sources will expire someday.

Traffic jams have appeared in many places of our country. So in the future, many interesting means of transport will be born by humans.

My dream means of transport is skycycling. In my opinion, it will br powered by solar energy and wind energy to avoid pollution and save fuel. Two people can sit on it. We can use it anytime and anywhere. It's won't take a lot of space. I think it will look like a big tube. People will pedal to move tubes in skyrails. With the use of morden techndogy, skycycking will be able to help us many things and it will make our life become better. Skycycling will be able to avoid traffic jam, pollution and it help us comtemplate sky more clearly.

Anh in the future, I hope people will make skycycling is the same as my dream.

I live in Vietnam and there are a lot of traffic problems in big cities in my country. Firstly, there are too many people using the roads especially in the rush hour when people run out to work and school or get home from those places. Secondly, there are too many vehicles on the road that leads to traffic jams. Another problem is that many roads are narrow and bumpy. Fourthly, there are traffic accidents every day so a lot of people lose their lives or are injured. So in order to travel on the roads safely, I think we should obey the traffic rules and traffic signs as well. Moreover, carefulness is very necessary.
