Solar Energy And The Atmosphere Slideshare

Energy released from the sun is emitted as shortwave light and ultraviolet energy.

The three types are. Solar energy main drawbacks the initial cost is the main disadvantage of installing a solar energy system largely because of the high cost of the semi conducting materials used in building one.

Implementing solar energy on a large scale would reduce its environmental footprint to a tiny fraction of its current levels. Availability of solar energy energy from the sun is abundant the earth receives 174 petawatts pw 1 74 000 terawatts tw of incoming solar radiation insolation at the upper atmosphere solar power systems installed in the areas defined by the dark disks could meet the world s current total energy demand.

Renewable energy solar power is also environmentally advantageous because its energy supply never runs out. The cost of solar energy is also high compared to non renewable utility supplied electricity. 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.

The highest energy ultraviolet does not reach the planet s surface at all. The earth atmosphere energy balance is the balance between incoming energy from the sun and outgoing energy from the earth.

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.

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. 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. Heating of the atmosphere solar energy reaches earth as electromagnetic radiation. Solar energy is becoming an increasingly important source of renewable energy generation in europe and the rest of the world.

Only about 7 of solar radiation is in the uv wavelengths. The second highest energy is also mostly stopped in the atmosphere. Sunlight will always shine upon the earth and as long as it does hold energy which solar technology can exploit.
