Chọn chủ đề 2 Comparing Different Energy Sources
(So sánh các nguồn năng lượng khác nhau)
Giải thích: Đoạn văn đi so sánh lợi ích và bất lợi của một số nguồn năng lượng khác nhau.
Tạm dịch:
Lựa chọn tốt nhất cho năng lượng có thể khó khăn. Năng lượng từ than đá là dạng năng lượng phổ biến nhất hiện nay vì các nhà máy than không tốn kém để xây dựng. Các nguồn năng lượng không tái tạo khác như khí đốt tự nhiên, sạch hơn than đá, nhưng chúng vẫn không tốt cho môi trường. Các quốc gia hiện đang chuyển sang các nguồn năng lượng tái tạo như gió, mặt trời và thủy điện. Các nhà máy điện gió và năng lượng mặt trời sạch sẽ và rẻ để chạy, nhưng chúng không rẻ để xây dựng. Các nhà máy thủy điện cũng không gây ô nhiễm, nhưng chúng có thể tốn kém để xây dựng và ảnh hưởng đến môi trường bằng cách ngăn cá di chuyển tự do. Vì những lý do này, các quốc gia và thành phố thường chọn kết hợp các loại năng lượng.
