306

Published on


Nepalese industries offer a huge potential to cut production cost by using energy more efficiently. It is estimated that around 15% of electrical and 30% of thermal energy could be saved in eight energy intensive industrial sector. This presentation contains the result of a study conducted by German Development Cooperation (GIZ) among 200 Nepalese industries in 2012.
