Tận dụng ánh sáng tự nhiên

Tận dụng ánh sáng tự nhiên nhiều hơn

Tận dụng ánh sáng tự nhiên nhiều hơn

Ánh sáng mặt trời tự nhiên sẽ tạo ra một môi trường học tập thoải mái hơn so với ánh sáng của bóng đèn điện thường có trong các lớp học. Các nghiên cứu cũng chỉ ra rằng ánh sáng tự nhiên giúp mọi người tập trung và tỉnh táo hơn và cải thiện tâm trạng của họ. Ngoài ra, việc tắt đèn sẽ giúp căn phòng mát hơn trong thời tiết nắng nóng đỉnh điểm mùa hè.

Chuyển sang sử dụng đèn LED

Một trong những lời khuyên tốt nhất về cách tiết kiệm điện ở trường là thay thế tất cả các bóng đèn sợi đốt và đèn huỳnh quang tiêu chuẩn bằng các loại đèn hiệu quả hơn. Đèn sẽ hoạt động cả ngày ở trường, khiến chúng trở thành một trong những chi phí quan trọng nhất liên quan đến việc cung cấp năng lượng cho trường.

Đèn LED tiết kiệm điện như thế nào?

Đèn LED tiết kiệm điện như thế nào?

Bóng đèn LED hiện đại có thể cung cấp hiệu năng chiếu sáng mạnh mẽ và tiết kiệm điện tốt. Những tiến bộ hiện đại trong điốt được sử dụng trong các bóng đèn này cho phép sản xuất bóng đèn giá cả phải chăng hơn, giúp chúng tiết kiệm chi phí hơn tại thời điểm mua.

Ứng dụng năng lượng mặt trời cho trường học

Trường học sử dụng đèn năng lượng mặt trời

Trường học sử dụng đèn năng lượng mặt trời

Đây là giải pháp hiện đại tiết kiệm năng lượng thông minh đã được nhiều nước trên thế giới áp dụng. Bạn có thể sử dụng điện mặt trời lắp trên mái hoặc thay thế đèn điện bằng đèn năng lượng mặt trời. Trong đó, đèn năng lượng solar khuyến khích nên lắp đặt tại các khu vực như: khuôn viên sân trường, cổng ra vào, sân thể thao, bãi để xe, hành lang,…

Lựa chọn các thiết bị làm mát tiết kiệm năng lượng

Chạy máy điều hòa để giữ cho trường học mát mẻ có thể tốn rất nhiều tiền, phải mất một lượng điện khổng lồ để bù đắp chi phí loại bỏ nhiệt do cả máy móc và hàng trăm cơ thể con người tạo ra trong thời tiết nóng nực. Chúng ta có thể nghĩ đến biện pháp thay thế bằng các thiết bị làm mát tiết kiệm năng lượng tốt hơn như hãng LG có thể tiết kiệm được 70% điện năng.

Bên cạnh sử dụng điều hoà, hãy sửa chữa các cửa sổ để chúng có thể mở để đón gió tự nhiên. Đầu tư vào quạt trần và các loại quạt đời mới tiết kiệm điện mà hiệu năng hoạt động cao.

Sử dụng đèn cảm biến chuyển động

Cảm biến chuyển động thông minh

Cảm biến chuyển động thông minh

Có nhiều không gian trong trường học chỉ thỉnh thoảng sử dụng đến ánh sáng. Tuy nhiên, để đảm bảo an toàn cho học sinh, nhiều trường bật đèn trong các phòng này như vậy có thể gây lãng phí điện không đáng có. Nếu bạn đang tự hỏi làm thế nào để tiết kiệm điện ở trường, bạn có thể cần đầu tư vào thiết bị đèn cảm biến chuyển động.

Chúng sẽ kích hoạt ánh sáng khi ai đó đi vào và tự động tắt đèn khi không có chuyển động trong một thời gian. Ưu điểm của thiết bị này là bạn không cần bận tâm đến việc bật tắt đèn, và chỉ khi có người qua lại chúng mới phát sáng nên sẽ tiết kiệm điện một cách tối đa.

Tắt đèn và các thiết bị điện khác sau giờ học

Tắt đèn sau khi rời khỏi phòng học và tắt nguồn máy tính, máy chiếu khi không sử dụng (đặc biệt là vào cuối ngày thứ Sáu và trước ngày lễ) có thể giúp giảm bớt việc sử dụng năng lượng.

Tất cả cá nhân cùng thực hiện tiết kiệm điện năng

Học sinh, cũng như giáo viên, nhân viên và quản trị viên, hãy cùng thực hiện các biện pháp để giảm lãng phí năng lượng ở trường. Giáo viên cũng cần đảm bảo rằng học sinh, sinh viên của mình hiểu tầm quan trọng của việc tiết kiệm điện năng tại trường học.

Với một chút giáo dục về cách giảm sử dụng điện ở trường, nhiều học sinh sẽ tự hào đóng góp cho những nỗ lực giúp tăng hiệu quả tiết kiệm điện năng.

Nowadays, energy is running out more and more. So we need to save energy because nobody of us can live without energy. There are many different ways to reduce your household’s energy use. Firstly, we need to adjust our day-to-day behaviors. To reduce energy consumption in your home, you do not necessarily need to go out and purchase energy-efficient products. You can also use energy-intensive appliances less by performing household tasks manually. Secondly, you can use an instant water heater. These water heaters last longer than traditional tank water heaters which makes them cost-efficient in away. Last but not least, we should turn off the light in a room when we go out or in unnecessary situations, avoid wasting water, shut the kitchen stove when stop cooking. Besides, we should use low light bulbs. In conclusion, from all the things mentioned above, I hope everyone should reduce the use of energy

Dear Mom and Dad,

I know, you do not need this thank you, but I am doing it for myself. I have never said it before, but you are the best parents one could ever get. Lucky me! You really mean the world to me; in fact I saw this world in your eyes. You gave me the wings to fly and explore this world on my own.

Thank you very much for love, care, and affection you had showered me. I may not be able to return that to you, but I want to say, I LOVE YOU!

And thanks for making me the most valuable person in your life. THANKS!!!

Love you,
