3)The first advantage of renewable energy is that it is renewable, has an extremely large reserve, and can be endless. Forms of energy such as solar, wind, geothermal, ocean waves, rain... are available and free to use, without fuel costs. Biomass energy also has large reserves and low fuel costs. Compared to traditional energy sources such as coal, oil, natural gas, which are increasingly depleted, only meeting human energy needs for about 50-70 years, this advantage is a strength. outstanding.
Despite many great advantages, renewable energy also has some disadvantages, such as Due to the impact of nature, renewable energy has lower stability than traditional energy sources. Solar energy can only be exploited during the day on sunny days, and at night or on cloudy and rainy days, the system will not work. Or with wind energy, wind turbines can only generate electricity at times when the wind speed is in the range of 4-25 m/s. The wind speed must be at least 4 m/s for the wind turbines to start running smoothly and generate electricity, but if it exceeds 25 m/s, the turbines will stop working to avoid damage in windy conditions strong.

4)Solar energy is a sustainable energy source for the future because it contributes to protecting the green environment, does not release any greenhouse gases during operation. The solar system will help customers get a source of savings on energy bills

5)1. Increase the temperature of the refrigerator
2. Set the washing machine to warm or cold water, not hot water
3. Make sure when washing dishes by machine, dishes and utensils must be fully lined up in the rack
4. Lower the temperature of the water heater
5. Should choose energy-saving products when replacing old household appliances
For heating and cooling:
6. Do not overuse heaters and air conditioners
7. Clean and change the filter regularly
8. Use energy-saving compact bulbs for the best light efficiency
9. Insulate the hot water system with a cost of only 10 - 20 USD but will save 450 kg of gas used for heating water
10. Use less hot water by installing a low-flow faucet
11. Air-conditioner in your house/apartment
12. Walk, bike, carpool or use public transport whenever possible
13. When you can afford to buy a new car, you should choose a fuel-saving type
14. Reducing household waste: Reduce, reuse, recycle
15. If your vehicle has air conditioning, it is recommended to recycle the refrigerant of this system
Improve your apartment/house
16. Insulation for walls and roofs
17. Modernizing the window system
18. Plant lots of trees and light-coloured walls
Business and community
19. Ask your boss to install energy-efficient appliances and implement solutions to save energy and reduce emissions in the workplace
20. Contact local and national environmental authorities, to give your opinion on the economical and efficient use of energy as well as environmental issues.
