‫So this lecture is about the basics of solar energy, as you know that what is solar energy?
‫Solar energy is also a type of renewable energy.
‫So renewable energy is that energy that is the source found in nature, which are self-generating.
‫So we can define solar energy as it is.
‫It is a source that is found in nature and this source is not self-generating.
‫So this is known as renewable energy source of energy, which can be used again and again in not exhaustible.
‫So as you know that from millions of years we can use solar energy, but it cannot be finished.
‫So this type of energy is not known as renewable energy.
‫So one is no non-renewable resources of energy.
‫So resources of energy are we are using up and cannot recreate this like coal, petroleum and natural
‫gas.
‫So coal, petroleum and natural gas are also found in nature, but they are not generated.
‫They are not self-generated.
‫When we use them, they are finished.
‫So the self, the self generating are known as renewable and then that which can be finished.
‫These are known as non renewable sources.
‫So all types of renewable energy, one is solar energy, the also type of renewable energy.
‫Wind energy is also a type of renewable energy, hydropower, biomass and geothermal.
‫These are type of energy are so are renewable energy.
‫So here in figure, you see these are different energies.
‫This is solar energy.
‫This is wind type energy.
‫These are these are biomass energy.
‫So hydropower, energy and geothermal, these all are the types of so renewable energy.
‫So here we can see solar energy.
‫Solar energy is the form of light and heat.
‫It is energy generated due to thermonuclear fusion reaction occurring in the sun.
‫So it is the most abundant available form of energy.
‫Energy.
‫So here you see this is thermal nuclear fusion.
‫When deuterium and tritium, these two elements react with each other, each other, then they can produce
‫helium and neutron.
‫And a lot of energy is generated in this process.
‫So this type of this is this is basically solar energy which comes from sun to earth.
