Sun is the ultimate source of energy.

It provides us energy both directly and indirectly.

We get sunlight and heat from Sun which keeps our earth warm and habitable. Solar energy can be used directly to produce electricity, cook, heat water etc with different instruments.

Solar energy helps all living organisms in many ways. Plants prepare their food in presence of sunlight which helps them grow. These plants are the source of all out conventional energies like coal, petrolium etc. which are formed when plants gets buried inside earth for millions of years. Thus, sun gives us energy indirectly too.
