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.

At present, most of our energy comes from fossil fuels (coal, oil and natural gas). However, reserves are limited. Because demand for electricity is rising rapidly, fossil fuels will be exhausted in a relatively short time. Therefore, people must develop and use alternative energy sources.

An alternative energy source is nuclear power. Nuclear power can provide enough electricity for the needs of the world for hundreds of years, but it can be very dangerous. An alternative source of geothermal energy comes from deep within the earth. Scientists use heat to generate energy. However, this energy is only available in some parts of the world.

Sun, water and wind are alternative sources of energy. Wind rotating the windmill and moving the sailboat. It's a clean source and a lot of energy. Unfortunately, if the wind does not blow, there is no wind energy. As water moves from one place to another, it makes energy. However, people have to build dams to use this energy source. The dams cost a lot of money, so water is expensive too.

The sun releases large amounts of energy each day. This energy can be converted into electricity. Many countries use solar energy for their daily lives. Solar panels on the roof can generate enough energy to heat or cool the entire home. Solar energy is not only abundant and infinite but also clean and safe.

Ngắn gọn hơn: There are some tips to save power which I think are very easy to apply. Firstly, we should use energy saving light bulbs in our house. It will help us to reduce our electricity bill. Secondly, we should use public transport if we need to go long distance. We can use bicycles for short distances. I think it is good for our health and economical. And remember, before going to bed, we should turn off all lights and other unused electrical devices. It's an easy way to save our planet.

Nowadays, energy is being run out more and more so it is one of the most important things of our life. We need to save energy because nobody of us can lives without energy. So why don't we start to do it right in our home? We have many ways to save energy in our home. One of those ways is using electricity, water and gas economically. Such as we should turn off the light in room when we go out or in unnecessary situations, avoid wasting water, shut the kitchen stove when stop cooking. Use a microwave instead of a stove to reheat food. Use rechargeable batteries instead of disposable batteries... Besides, we should use electrical equipments which are energy - saving. Such as using lights and fans that have low capacity, or using equipments which reserve electricty. Not only do these help us to save money but also they work effectively.
In addition, we should frequently check electrical equipments in our home in order to fix opportunely. In summary, we need to save energy so that energy isn't run out and continues to serve human's life.

Nowadays, energy is necessary for our life. There are many kind of energy : ocean energy, electric energy, solar energy, wind energy... But energy also limit , so we must save energy. We can make some following ways.
To save petrol energy, we should:
+ Limit travel by car, motorbike, train...
You can using bicycles or walk.This not only help you save energy but also avoid traffic jams and can save your money any more.
- To save electricity energy, we should:
+ Turn off the light , the fans, the air-conditioner, you should close it after using.Avoid ironning close at peak hours...
+ When buying somethings, we should choose devices with costly a low electricity.
There are many ways to save water:
+ Turn off the faucet after using it
+ Don't let children play with water, if you let chidren play with water , this ill a lot of water.

- In the kitchen we should save gas energy by many ways:
+ turn off gas after cooking
+ don't use gas too much
+ when the food ripe, we should turn off gas immidiately to save gas.
- saving energy is our duty.
If you follow ways above, you can not only save energy but also save money very much and protect the environment.
