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.
Renewable energy describes a collection of energy technologies i.e. solar, wind, geothermal derived from sources that are never-ending and can be replenished time after time. Most countries across the world heavily depend on fossil fuels (oil, coal andnatural gas) as sources of energy to power their economies.
Fossil fuels are non-renewable forms of energy, meaning, they utilize limited resources that will ultimately deplete, hence, driving up overall energy costs. These very countries have responded to the threat by stepping up campaigns to embrace renewable forms of energy like solar and wind
In Vietnam there are a lot of traffic problems in my country. First, there are too many people using the roads in the rush hour. Second, there are too many vehicles on the road that leads to traffic jams. Another problem is that many roads are narrow and bumpy. Fourth, there are traffic accidents every day so a lot of people are injured. I think we should obey the traffic rules and traffic signs as well.
Non-recoverable energy sources, such as coal, gas, have been exploited by humans for a long time . These kinds of energy take a very long time to form. However, its consumption happens so fast that it causes the problem of depletion of natural resources as well as pollution.
Meanwhile, renewable energy sources such as wind, solar, and water are available in abundance and availability. However, the exploitation of this energy source requires modern and complex equipment.
Renewable energy source promises to be the energy source of the future. They are friendly to the environment. We should make use of them and reduce the reliance on non-renewable resources.

Renewable energy comes from a source that will not deplete. Two common examples of this type of energy are solar power and wind power. Geothermal power, hydropower, biomass, and tidal power are additional forms of renewable energy that produce power for our planet right now.
The primary advantage of renewable energy is that fewer potentially harmful emissions are released into the atmosphere. Although fossil fuels are used to create the products that allow for this power to be produced, most forms of renewable energy can become carbon neutral in 5 years or less.
The disadvantage of renewable energy is that it can be costly. Although wind power and solar power have become cost-competitive with coal-fired power and nuclear power in some communities, some forms are not cost-competitive globally yet when the cost per kilowatt hour is compared. In 2015, the lifetime cost per kilowatt hour of conventional coal was 9.5 cents, while the cost of offshore wind was 15.8 cents.
There are additional advantages and disadvantages of renewable energy to consider as well.
