Fossil Fuels
The chemical energy in thermal power stations, heating systems, and vehicle engines is transformed into thermal energy through the chemical reaction of combustion.
Radioactive substances
The atoms of these substances can thus undergo nuclear reactions that release large amounts of nuclear energy, which can be transformed into thermal energy.
Renewable energy sources
Stored water
Wind
The Sun
The Erth's heat
