The main source of heat is the Sun.
The main source of energy and heat is the sun.
Cooking uses heat energy as the main source. It is the main activity that uses heat as a source of energy.

The main source of heat that makes water on the earth evaporate is the thermal energy from Sun.
The main energy source for a reaction is typically provided by heat, light, or electricity.
The main source of energy that heats the Earth is the Sun. Solar radiation is absorbed by the Earth's surface and then re-radiated as heat. The Earth's atmosphere traps some of this heat, leading to the warming of the planet.
Heat energy can be transferred from a source to a receiver through three main mechanisms: conduction (direct contact transfer of heat between objects), convection (transfer of heat through a fluid, either liquid or gas), and radiation (transfer of heat through electromagnetic waves without the need for a medium).
