4. RAG322 SAINS PERSEKITARAN 2 PENGURUSAN TENAGA Pbp usm expg@tm.net.my mzin@usm.my Kecekapan Tenaga (KT) Penggunaan tenaga yang cekap yang biasanya dinamakan Kecekapan Tenaga (KT) bermakna menggunakan tenaga dengan bijak dan secara produktif bagi menyempurnakan tugas yang sama. Strategi tenaga ke-5 ialah dengan mempromosikan kecekapan penggunaan tenaga terutama dalam sektor perniagaan/perdagangan dan perindustrian. Malaysia boleh mencapai penjimatan satu pertiga daripada penggunaan tenaga tahunannya melalui usaha yang telah dilaksanakan dengan jayanya, seperti Projek Peningkatan Kecekapan Tenaga Industri Malaysia (MIEEIP).
