Our society runs on energy, which is produced in many ways, including the combustion of fossil fuels like coal and gasoline. Too often, harmful substances are released when producing or using energy. These waste products cause air and water pollution and may contribute to global warming.
Biological and agricultural specialists are developing alternative energy sources, such as plant-based fuels and solar power systems. These energy options may help sustain our quality of life while reducing adverse effects on the environment. These specialists also seek ways to conserve energy and improve the environment using current technology. Alternative energy is a growing field, and energy conservation will pose ongoing challenges for the future.
