2)Factor on energy saving

*Architecture aspects

-building orientation

-heat and light proof materials

-smart building

3)Equipment design

*Energy saving

*Energy eficiency

Advantage

•The renewable resources are

nearly infinite

•A very large amount of energy

could be generated in this way

•A barrage could be used in various ways: as a bridge or as

a barrage against flooding

Disadvantages

•Sunlight is only found during the daytime which makes it

inconvenient to use at night.

•Wildlife could be affected

•Construction of barrage could

be expensive

By today, i learned:

1. We need to conserve as much energy we can because energy resources can be exhausted after a long time.

2. What can we do to reduce the consumption of energy are recycle, turn off electrical equipment when not used and replace old light bulbs with energy saving fluorescent bulbs.

3. Factors on energy saving are

   1. architecture aspect

   2. Equipment design

   3. Maintenance of energy management

Kepentingan tenaga terbahagi kepada tiga iaitu:-

1) komuniti

2) Ekonomi dan politik

3) Industri

Jenis tenaga terbahagi kepada 2 jenis iaitu :-

1) Tenaga boleh diperbaharui. Contoh, tenaga solar, tenaga angin, biomass dan tenaga air

2) Tenaga yang tidak boleh diperbaharui. Contoh, bahan api, arang dan gas

Kebaikan tenaga boleh diperbaharui:

1) boleh diperbaharui tidak kira jumlah

2) nilai yang besar

Energy management is a crucial practice aimed at optimizing energy use to reduce costs, enhance efficiency, and minimize environmental impact. As global energy demands rise and the effects of climate change become increasingly apparent, effective energy management has gained prominence across various sectors. This essay explores the essential components of energy management, including energy audits, efficiency improvements, monitoring and control systems, demand response, renewable energy integration, and behavioral changes.

>Tenaga yang boleh diperbaharui

-angin

-solar

>Tenaga yang tidak boleh diperbaharui

-petroleum

-batu arang

Kelebihan renewable energy
