Globally 1.3 billion people—one in five globally—lack electricity to light their homes or conduct business. Twice that number—nearly 40% of the world's population—rely on wood, coal, charcoal, or animal waste to cook their food—breathing in toxic smoke causing lung disease that kills nearly four million people a year, most of them women and children.
For the industry and commercial activities the lack of reliable power and high fuel costs represent significant challenges for doing profitable businesses, while the noice and pollution from generators are daily nuisance.
In addition, the use of tradional and fossil fuels contribute climate change. The cutting down of trees for firewood and charcoal contributes to desertification that reduces the earth's capability to handle CO2, while the soot particles (particulate matter) reduce the radiation from the earth to space. The use of fossil fuels contributes with additional CO2 in the atmosphere.
