Dear guests, I'd like to talk to you today about renweable and non-renewable energy. Fossil fuel are non-renewable energy sources. They include oil, coal, and natural gas. They can be used to create energy, generate electricity, or drive big machinery. Unfortunately, they are harmful to the environment. Viet Nam still relies mostly on non-renewable energy sources, however, hydro power is increasingly used here too. Hydro and nuclear power can generate a great deal of energy. They are renewable and plentiful. However, hydro power is limited because dams cannot be built in certain areas. Nuclear power can provide enough electricity for the world's needs, but it is dangerous. The sun and the wind are other alternative sources of energy. The wind turns turbines to make electricity. Solar power can be converted into electricity. It can be used to heat or cool our houses. Although there are some disadvantages, these alternative energy sources can offer abundant amounts of clean, safe electricity. They will be valued more and more in the future in Viet Nam.

Kính thưa các vị khách quý, hôm nay tôi muốn nói với các bạn về năng lượng tái sinh được và năng lượng không tái sinh được. Năng lượng hóa thạch là năng lượng không tái sinh được. Chúng bao gồm: dầu, than đá, khí đốt tự nhiên. Chúng có thể được sử dụng để tạo ra năng lượng, tạo ra điện hay vận hành các cỗ máy lớn. Thật là không may, chúng lại độc hại cho môi trường. Việt Nam vẫn phụ thuộc chủ yếu vào các nguồn năng lượng không tái sinh được, tuy vậy năng lượng nước cũng đang ngày càng được sử dụng nhiều. Thủy điện và hạt nhân có thế tạo ra rất nhiều năng lượng. Chúng rất dồi dào và có thê tái phục hồi. Tuy nhiên, thủy điện có hạn chế bởi vì các đập nước không thể xây dựng ở một số vùng. Năng lượng hạt nhân có thể cung đủ điện cho nhu cầu của toàn thê giới nhưng nó lại rất nguy hiểm. Mặt trời và gió là những nguồn năng lượng thay thế. Gió làm quay các tua-bin và tạo ra điện. Năng lượng mặt trời có thế chuyển hóa thành điện. Nó có thể được sử dụng để làm nóng hoặc làm mát nhà của chúng ta. Mặc dù có một số bất tiện, những nguồn năng lượng thay thế này có thể mang đến rất nhiều điện an toàn và sạch. Chúng sẽ trở nên ngày càng được xem trọng ở Việt Nam trong tương lai.

Example: Hydro power is a renewable source of energy because it comes from water. It is cheap and plentiful. Unfortunately, dams can only be built in certain areas .
Wind power
Ảnh
Wind power is a renewable source of energy because it is free. It comes from wind. It's abundant. Unfortunately it isn't always available and it isn't cheap.
Solar power
Ảnh
Solar power is a renewable source of energy because it comes from the sun. It's abundant, clean and safe. Unfortunately it isn't cheap.
Coal and natural gas
Ảnh
Coal and natural gas is a non-renewable source of energy because it can be used up. If s very cheap but it's polluting. It's not friendly to the environment.
Biogas
Ảnh
Biogas is a renewable source of energy because it comes from the waste of cattles and animals. It's plentiful and safe but it's not easy to use.
