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 formof solar radiation. Solar powered electrical generation relies on photovoltaic.e.g.:- Solar photovoltaic cells(solar panels), Heat Engine, solar heat collectorsSolar 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 constantin 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 photovoltaics (CPV) systems1.CVP- 9. Concentrated solar power:- also called concentrating solar power and CSP systems use mirrors or lenses to concentrate a large area ofsunlight, or solar thermal energy, onto a small area. Electrical power is produced when the concentrated light isconverted to heat, which drives a heat engine connected to anelectrical power generator 10. Photovoltaic Power Plants type- Ground based solar system Space solar power (SSP) system 11. SSP- SOLAR SPACE POWER Space-based solar power (SBSP) is the concept of collectingsolar power in space for use on Earth It has been in research since the early 1970s. The SBSP concept, originally known as Satellite Solar PowerSystem (SSPS), 12. 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 13. 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 Earths 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. 14. The SSP concept :- 15. Why in Space ? 16. 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 (Earths shadow on satellite comes only 16 minutes) Higher collection rate: In space, collection in orbit is approximately 144% of the maximum attainable on Earths surface. Longer collection period: 17. See VIDEOs ** 18. THANK YOU !!! ANY QUWRY ? Presented By-Ravi Yadav
