What type of energy is produced by waste to energy plants?

Waste-to-energy plants primarily convert waste materials into usable energy through processes such as combustion. The main output from these plants is electricity generated through steam turbines. When waste is burned, it produces heat, which is then used to convert water into steam. This steam drives turbines that generate electricity. Additionally, some plants can use the heat directly to provide steam for industrial processes or district heating systems.

While heat energy is produced, it is primarily this heat energy that gets converted into electricity or steam for further use. Therefore, the choice that encompasses both forms of energy—electricity and steam—accurately reflects what waste-to-energy plants produce.
