2b. Energy Conversion
Energy, or the ability to do work, can be transferred from one form to another. For example, the mechanical energy of a compressed spring can be transformed into motion energy when the spring is released. Explore more examples of energy transfer by moving the sliders back and forth.
Lignite-fired plants like those in North Dakota use energy conversion to generate electricity. Expand the accordions to learn more.
Chemical Energy to Thermal Energy
Coal, which contains chemical energy, is burned, creating thermal energy, and radiant energy!
Thermal Energy to Motion Energy
The thermal energy is used to heat water into steam. As steam passes through a turbine, the turbine spins, changing thermal energy into motion energy.
Motion Energy to Electrical Energy
The turning turbine is attached to a generator. As the generator turns, electricity is generated.
