A study on Monday showed that More than a billion.people are at risk from lack of air conditioning and refrigeration to keep them cool and also to preserve food and medicines as global warming brings more high temperature to the scene.
More electricity demand for fridges, fans and other appliances will add to man-made climate.change unless power generators shift from fossil fuels to cleaner energies, according to the report by the non-profit Sustainable Energy for All group.
In a survey of 52 countries, those most at risk included India, China, Mozambique, Sudan, Nigeria, Brazil, Pakistan, Indonesia and Bangladesh, it said.
"We have to provide cooling in a super-efficient way," Kyte said. Companies could find big markets, for instance by developing low-cost, high-efficiency air conditioners to sell to growing middle classes in tropical countries.
And simpler solutions, such as painting roofs white to reflect sunlight or redesigning buildings to allow heat to escape, would also help.
The U.N.'s health agency says that heat stress linked to climate.change is likely to cause 38,000 extra deaths a year worldwide between 2030 and 2050. In a heat-wave in May, more than 60 people died in Karachi, Pakistan, when heat rose above 40 degrees Celsius (104°F).
In remote areas in tropical countries, many people.lack electricity and clinics are often unable to store vaccines or medicines that need to be chilled, the study said. And in city slums, electricity supplies are often intermittent.
Many farmers or fishermen, meanwhile, lack access to a "cold chain" to preserve and transport products to markets. Fresh fish goes off within hours if stored at 30 degrees Celsius (86°F) but stays fresh for days when chilled.
