because you can get it without buying it
it is alternative.
why could you consider the sun ''free enegery''
If by 'leaf factory' you mean the leaves of plants, then the source of free energy is the Sun, in the form of sunlight form the Sun.
we could not. if the sun ran out of light, or solar energy we could not renew it. but I don't think that the sun will run out of solar energy.
'Solar' means 'to do with the Sun' so you don't need to use the two words together. Solar energy is from the Sun, so it arrives free at the Earth. The only cost is in making and maintaining the receptors to turn the solar energy into useful energy for mankind.
99.9% of Earth's energy comes from the Sun. It is usual, especially in the natural water cycle for the energy to evaporate water to come from the Sun. Of course you could also use the heat from a nuclear reactor.
No. Frogs would not survive without energy from the sun. A frog's food source depends upon the energy of the sun for its food. Without the sun, the frogs would not have food.
some people say it isnt if its the sun, so if u mean the the sun then no, it is not renewable. solar energy itself, you PROBABLY could...
YES!!!why???becauze the heat of the sun could penetrate the erth but it could be hard...once it enters the erths core it would be only 1% or 0.001% of the given energy of the sun....
It is economical to consider installing solar panels because we need the energy for our planet. The sun provides it all and solar panels would save energy and money.
I believe none. The amount of other energy available would be insignificant, and without energy from the Sun, it would get extremely cold.
Short answer, NO The sun is the source of all energy and life on earth
