Solar power on earth
Every day, around 1367 watts per square meter (W/m^2) of solar radiation hits our planet! That amount may seem small – but it’s more than enough to power many of our daily activities and needs when harnessed correctly. So where does all this energy come from?

This energy goes towards weather, keeping the temperature of the Earth at a suitable level for life, and powers the entire biosphere.
What is solar energy & how does it affect the Earth?
Not all of the sunlight that strikes the top of the atmosphere is converted into energy at the surface of the Earth. The Solar energy to the Earth refers to this energy that hits the surface of the Earth itself. The amount of energy that reaches the the Earth provides a useful understanding of the energy for the Earth as a system.
Is solar energy the future of energy on Earth?
Our Verdict: Solar Energy is the Future of Energy on Earth! Solar energy is a renewable and clean form of natural energy that has the potential to power our world. It can be collected from the sun’s rays and converted into electricity or thermal energy for homes, businesses, and industries.
How does solar energy work?
Solar energy acts as a that can be harnessed. Almost all of the Earth 's energy input comes from the sun. Not all of the sunlight that strikes the top of the atmosphere is converted into energy at the surface of the Earth. The Solar energy to the Earth refers to this energy that hits the surface of the Earth itself.
How much solar energy does the Earth receive?
In addition to being free as a source of energy (it does cost money to harness it and turn it into electricity), energy from the sun is practically limitless. The surface of the Earth receives solar energy at an average of 343 W/m 2. If we multiply this times the surface area of the Earth, about 5x10 14 m 2, we get 1715x10 14 W.
How can solar energy be used?
Solar energy can be used to produce heat, cause chemical reactions, or generate electricity. The total amount of solar energy incident on Earth is vastly in excess of the world’s current and anticipated energy requirements.
