Fossil fuel, solar (radiant), electrical, and geothermal.
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 light is the sun

The main source of heat that makes water on the earth evaporate is the thermal energy from Sun.
The three main components of an exothermic wave are the heat source, the reaction front, and the heat release pattern. The heat source initiates the reaction, typically through an exothermic chemical process. The reaction front represents the advancing wave of heat and reaction products, while the heat release pattern describes how heat is distributed over time and space as the reaction progresses. Together, these components illustrate how energy is released and propagated through the medium.
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.
The main energy source for a reaction is typically provided by heat, light, or electricity.
