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.
