Final answer:
Solar cookers could replace fossil fuels as an affordable source of energy in rural villages in third world countries.
Step-by-step explanation:
Solar cookers could replace fossil fuels as an affordable source of energy in rural villages in third world countries. Solar cookers use the greenhouse effect and reflective material to trap and retain solar energy, making them an inexpensive and efficient way to cook food without relying on traditional fuels. These cookers have been developed since the 1950s and are particularly valuable in countries with limited energy availability. They can save money, reduce labor, and have a positive environmental impact by reducing the use of kerosene and carbon dioxide emissions.
