Kecekapan Tenaga (KT) PENGURUS AN TENAGA • 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).
