Yulia: Hello, Mai. How are you?

Mai: Hi. I'm fine. Thanks!

Yulia: Can I ask you some questions for sources of energy?

Mai: Okay!

Yulia: What are renewable energy sources and what are their advantages and disadvantages? 

Mai: Renewable energy sources are solar power, hydro power, wind power etc.
Hydro power is plentiful and it can generate a great deal of energy. However, hydro power is limited because we cannot build dams in some certain areas. Solar power and wind power is convenient and abundant but sometimes they are not available.

Yulia: And what are non-renewable energy sources and what are their advantages and disadvantages?

Mai: Non-renewable energy resources are fossil fuels like coal, oil and natural gas. They are abundant but they are harmful to the environment. They will possibly be used up one day, which could lead to a shortage of energy.

Yulia: What types of energy does Vietnam use most? 

Mai: In Vietnam, people use both non-renewable energy sources like coal, oil, natural gas and renewable ones like hydro and solar power. Vietnam still relies mostly on non-renewable energy resources. However, hydro power is increasingly used. In some areas, people also use solar power to heat water and biogas is used for cooking

Yulia: Uhhh, what can we do to save energy?

Mai: I think we can save energy by using renewable energy like solar power or wind power instead of fossil fuels. We should use public transport, use less electricity or only use as much water as we need.

Yulia: Ok, thanks for your answers. See you~

Mai: See you~
