A standard value of solar constant is 1353 τ𝑊 𝑚2. The earth atmosphere energy balance is the balance between incoming energy from the sun and outgoing energy from the earth. The three types are. Solar energy is becoming an increasingly important source of renewable energy generation in europe and the rest of the world.

Sunlight will always shine upon the earth and as long as it does hold energy which solar technology can exploit. Implementing solar energy on a large scale would reduce its environmental footprint to a tiny fraction of its current levels. Solar constant isc solar constant isc. Total energy received from the sun per unit time on a surface of unit area kept perpendicular to the radiation in space just outside the earth s atmosphere when the earth is at its mean distance from the sun.

The highest energy ultraviolet does not reach the planet s surface at all. If you continue browsing the site you agree to the use of cookies on this website. Heating of the atmosphere solar energy reaches earth as electromagnetic radiation. Specifically it focuses on the effect solar energy has on ea this powerpoint explores how the sun s radiant energy affects the different layers of atmosphere.

The second highest energy is also mostly stopped in the atmosphere. The cost of solar energy is also high compared to non renewable utility supplied electricity.

While the total share is still fairly low at just above 1 of global energy generation the annual growth is almost exponential at about 30 per year.

Only about 7 of solar radiation is in the uv wavelengths. Duran slideshare uses cookies to improve functionality and performance and to provide you with relevant advertising. Energy released from the sun is emitted as shortwave light and ultraviolet energy. When it reaches the earth some is reflected back to space by clouds some is absorbed by the atmosphere and some is absorbed at the earth.

Of the solar energy that reaches the outer atmosphere uv wavelengths have the greatest energy. Almost half of the solar energy that enters the atmosphere passes through and reaches earth s surface the rest is absorbed in the atmosphere by clouds gases and dust. Renewable energy solar power is also environmentally advantageous because its energy supply never runs out.
