Yes.
Wind energ Warm air rises up and cold air settles down. Similarly, due to uneven heating of the earth.s surface by the sun rays at Dwo different adjoining Places, a pressure difference is created and wind is produced.
Wave energy: Strong winds are generated due to the sun and the waves are generated by strong winds blowing across the sea.
Ocean thermal energy The difference in temperature berween the water at the surface and water at depth in seas and oceans is due to the sun.
Energy from fossil fuels: Fosil fuels [coal, petroleum, ete.] are tormed when large plants and ancient creatures are buried deep inside the earth.s crust under the effect of a lot of pressure and heat.
Solar energy: The phenomenon of photoelectric effect generation of electricity by light) is possible only in the presence of sun.
Blomass: Plants convert the solar energy into chemical energy with the help of inorganic substances [i.e., air, water, etc.] These plants are consumed by plants and animals to produce wastes from which energy is obtained.
Energy from flowing water: Water from sea and rivers evaporates and falls at different places of the earth as snow and rainfal. This water collected in a dam, when allowed to flow, rotates the turblne of a generator and electricity is produced.
