RENEWABLE ENERGY SOURCES ON THE EARTH-

   The Earth’s Energy Input is Nearly Entirely Implanted of Incident Radiation. This Amounts to 173,000 TW. Tides and Therefore The Heat Supply within the Planet (Mostly Radioactivity) also Quantity Contribute Concerning 3 TW and 32 TW, Severally to The Energy Input. Around 52,000 TW (i.e Concerning 30% of The Incoming Solar Radiation) is Mirrored Back to the Region. The Remaining Energy is Degraded to Heat and Re-Emitted as Radio Wave Infrared. 

Table (1) Represents the Energy Balance Processes on The Planet. The Relative Stability of The Earth’s Temperature Indicates the Balance between Planetary Input and Output of Energy.

Table 1- 

Energy Balance Processes on The Planet-

The Source of Energy Available to Mankind are Broadly Classified into Two Forms That are Renewable and Non-Renewable. The Energy used by Mankind Originates from

• Radiant Energy Emitted by The Sun (Solar Energy and its Derivatives). 
• Geothermal Energy from The Interior of Earth. 
• Tidal Energy Originating from The Gravitational Energy from The Moon. 
• Nuclear Energy.

What is a SOLAR ENERGY? 

   Solar Energy is an Alternate Source of Power, The Supply of Solar Energy is Limitless Unlike Fossil Fuels such as (Coal, Natural Gas, Oils Etc). The use of Solar Energy Produces No Water or Air Pollution. 

Solar Energy is Becoming The Primary Source of All Over The World. 

The Solar Energy can be Converted Electricity in Two Ways-

1. Solar Cells, to Change Sunlight Directly into Electricity. 
2. Solar Power Plant, Uses Solar Thermal Collectors to Indirectly Create Steam that is used to Power Generators.
