The World Health Organization warns that millions of people are dying every year from indoor air pollution．Nearly three billion people are unable to use clean fuels and technologies for cooking，heating and lighting．
These findings show that the use of deadly fuels in inefficient stoves，space heaters or lights is to blame for many of these deaths．
WHO officials say indoor pollution leads to early deaths from stroke，heart and lung disease，childhood pneumonia and lung cancer．Women and girls are the main victims．These diseases can often result from the burning of solid fuels．These fuels include wood，coal，animal waste，crop waste and charcoal．
The United Nations found that more than 95 percent of households in sub-Saharan Africa depend on solid fuels for cooking．It says huge populations in India, China and Latin American countries，such as Guatemala and Peru，also are at risk．
Nigel Brace is a professor of Public Health at the University of Liverpoo1．He says researchers are developing good cook-stoves and other equipment to burn fuels in a more efficient way .There are already multiple technologies available for use in clean fuels．There is really quite an effective and reasonably low-cost alcohol stove that is made by Dometic(a Sweden-based company)that is now being tested out．LPG(liquified petroleum gas)cook is obviously widely available and efforts are under way to make those efficient．Another interesting development is electric induction stoves(电磁炉)．WHO experts note some new，safe and low-cost technologies that could help are already available．In India, you can bay an induction stove for about $8．00．And in Africa you can buy a solar lamp for less than$1.00．
But，this，the agency says，is just a start．It is urging developing counties to use cleaner fuels and increase access to cleaner and more modern cooking and heating appliances．
