Energy conundrum of developing economies
• 40% people rely on wood, charcoal, or animal waste to cook their food
despite the availability of technical solutions.
• 2 million people die annually from diseases caused by indoor smoke –
more than deaths from malaria.
• An estimated 1 billion people use health services without electricity.
• Over 291 million children go to primary schools without access to any
electricity.
• Almost 50% of vaccines in developing countries are ruined due to poor
cold chain services.

4. 4
Way forward–NZEB for developing economies
• Much can be achieved by the committed, within the current energy
policy framework
• SunCarrier Omega Net-Zero Energy Building , India - An empirical
model of decentralized off-grid energy system
• Attractive for deployment in developing economies due to the ease
of design, installation, commissioning and maintenance
• A design life of 25 years; ROI within 10 years
• Use-cases in Rural Electrification, Residential and Commercial
buildings, Telecom Tower Electrification, un-interrupted power for
Industry, Energy Security (Healthcare) …
