2. Renewable energy :-
 Renewable energy is energy which comes from natural
resources such as sunlight, wind, rain, tides, and geothermal
heat.
 which are renewable (naturally replenished)
 Renewable energy provides 19% of electricity generation
worldwide.

3. Types :-
 Wind power
 Hydropower
 Solar energy
 Biomass
 Biofuel
 Geothermal energy

4. Solar Energy :-
 Solar energy is the energy derived from the sun through the form
of solar radiation.
 Solar powered electrical generation relies on photovoltaic.
e.g.:- Solar photovoltaic cells(solar panels), Heat Engine,
solar heat collectors
Solar energy utilization

5. Why it is required soon ?
 From last century mostly the power is produced by Hydro Carbon fuel.
 Conventional and Hydro Carbon energy resources are constant
in nature .
 Soon conventional resource will go to finish .
 Sun power is longtime and reliable , (it have very long term commitment)

6. Top oil Importers :-

7. How it produce Electricity ?
(by solar panels)

8. Solar panels-
 Flat plate solar collectors system
 Concentrated photovoltaic's (CPV) systems

CVP-

9. Concentrated solar power:-
 also called concentrating solar power and CSP
 systems use mirrors or lenses to concentrate a large area of
sunlight, or solar thermal energy, onto a small area.
 Electrical power is produced when the concentrated light is
converted to heat, which drives a heat engine connected to an
electrical power generator

11. Photovoltaic Power Plants type-
 Ground based solar system
 Space solar power (SSP) system

12. SSP- SOLAR SPACE POWER
 Space-based solar power (SBSP) is the concept of collecting
solar power in space for use on Earth
 It has been in research since the early 1970s.
 The SBSP concept, originally known as Satellite Solar Power
System (SSPS),

13. SSP Built in Components :-
 A Satellite
 Concentrating mirrors
 Photovoltaic cell convertor (sunlight to Electricity)
 Microwave transmitter / LASER Transmitter
 Microwave/ LASER converter (MW to Electricity) **
 Power controller & distribution

14. Method:-
 It use the method of collecting the Solar power in space and
then supply on to the Earth by means of transmitting power
in the form of Microwaves , LASER beam.
 method of transmitting power over long distances .
(e.g., from an SPS to Earth's surface) using microwaves from a
very large antenna (up to one square kilometer) on the
satellite to a much larger one, now known as a rectenna, on
the ground.

15. The SSP concept :-

17. Why in Space ?

18. • No air & clouds in space, so the collecting surfaces could
receive much more intense sunlight, unobstructed by weather
 A satellite could be illuminated over 99% of the time
(Earth's shadow on satellite comes only 16 minutes)
 Higher collection rate: In space,
 collection in orbit is approximately 144% of the maximum
attainable on Earth's surface.
 Longer collection period:
