With fast growth of civilization there is also an ever mounting need for energy. Energy may be in the form of fuels or electricity. Petrol is a liquid fuel which is used widely nowadays. But this kind of fuels is likely to be exhausted at the rate man is using it recently.

To meet the challenge, various methods have been suggested. One is to minimize the man’s demand in using the energy. Non-essential consumption should be minimized. During certain days of the year, people all over the world turn off the electricity for 1 hour to save the energy. Modern gadgets consuming energy should only be used when they are absolutely necessary.

Energy conservation is possible through modernization of plant and equipment. People should replace the obsolete equipment by the modern ones.

Energy can be saved on transport by the following methods. People should commute by the rail rather than by cars and vans. The transport must be improved with a view to sparing the energy. Cities must be planned in such a way that the commuting distance from this place to others is minimized.

In industry, many things could be done to reduce waste of energy or to economize energy. The machine maintenance needs to be tightened; heater must be utilized properly. When systems are streamlined, economy in fuel is obvious. Instead of using materials requiring higher energy, those which require lower energy should be used.

We hope man with his ever rising urge for existence will cope up with this urgent problem and find alternatives.

Do you think of using electricity power wastefully every day? Do you know that many countries without electricity power? In Viet Nam, the people in remote mountains as Ha Giang, Lang Son province,…..have used oil lamp instead of electricity power.

BÀI DỊCH

Bạn có thấy mình sử dụng điện hoang phí mỗi ngày không? Bạn có biết rất nhiều nơi trên thế giới không có điện? Ngay tại Việt Nam, những người dân tại các vùng núi hẻo lánh Hà Giang, Lạng Sơn,…vẫn phải sử dụng ngọn đèn dầu thay vì điện.

Điện là một trong những nguồn năng lượng quan trọng nhất đối với cuộc sống. Bạn có thể thực hiện các sinh hoạt hàng ngày như ăn uống, tắm rửa, giải trí,…đều sử dụng năng lượng điện, ngay cả khi tôi đang dùng Laptop để viết bài luận này. Bạn có nhớ mình đã phát điên như thế nào nếu một ngày không có điện, đặc biệt khi nhiệt độ mùa hè 40 độ. Bạn đang dùng điện tiết kiệm chứ? Hay sử dụng một hoang phí? Còn riêng tôi, thật đáng xấu hổ vì nhiều lúc mình đã không biết tiết kiệm điện, và khi đọc những bản tin về người dân vùng cao sử dụng chai nhựa để làm bóng đèn, trong khi đó đèn được bật sáng ở mọi nơi thì tôi lại cảm thấy nghẹn lòng.

Bạn thân mến! Đã đến lúc chúng ta nên học cách tiết kiệm điện, đó là cách bạn cứu lấy cuộc sống của mình và mọi người xung quanh. Và hãy hưởng ứng Giờ Trái Đất các bạn nhé!
