These include portable solar panels, solar chargers and solar lights. In addition, new solar innovations are being introduced to the market every day and widely applied. Therefore, among the various advantages of solar energy, the main advantage is that it can be accessed and installed by almost everyone.The use of solar power may not completely replace the grid power, but it will reduce the monthly electricity bill of the family.However, in order to use solar technology, it is necessary to ensure: the direction of receiving the sun, the direction of wind, the width of space.

There are many ways to save energy.

Firstly, you should turn off the lights before going to bed or going out. You should use low energy light bubls or reduce our electricity bills. Secondly, you can also use public transport instead of cars, motorbikes, ... and we should increase the tax on petrol so that people use less petrol. It makes the air will be fresher and less toxic fume. Besides, you should reduce the use of fossil fuels and use other alternative sources of energy. Moreover, you should avoid using cars or motorbikes for short distance so you can save energy. 

To sum up, saving energy is very good for us and our environment. Using less electricity, using energy saving light bubls and using public transport are three main ways to prevent our energy from being limited.
