1. Nuclear power plants: in nuclear power plants, the nuclear energy is obtained when uranium atoms are bombarded with neutrons. The uranium atoms break into smaller atoms through a process of fission, hence releasing nuclear energy. The nuclear energy obtained is converted into thermal energy. The kinetic energy of steam obtained through this is converted into kinetic energy of turbine which thus helps us obtain electrical energy.

2. Solar thermal power plant: Thermal energy is obtained from solar radiation in solar thermal power plants. Many reflectors reflect and concentrate solar radiation on absorbers. There, the solar energy is converted into thermal energy. The thermal energy obtained from solar radiation is used to drive the turbine which thus helps in the generation of electricity in solar thermal power plants.

Answer 2

Answer:

Other than thermal power plant, nuclear power plants, solar power plants use thermal energy for power generation. Different ways of generating thermal energy are:

• Using fossil fuels: By burning, fossil fuels such as coal, petroleum, the chemical energy stored in them is converted into thermal energy.

• Using natural gas: Chemical energy in natural gas is converted into thermal energy.

• Using nuclear fuels: Controlled chain reaction in nuclear power plants releases huge amount of thermal energy.

• Using solar energy: Solar energy can be reflected and absorbed in aborbers where it gets converted to thermal energy.  

• Using geothermal energy: Underground water, sometimes, comes in contact with hot spots (where hot molten rocks are found), and thus steam is generated which is then collected via hot springs. Thus, geothermal energy is converted to heat energy.
