ABSTRACT
Amidst concern that the worlds oil and other fuel resources are finite and depleting .Due to the problems associated with the use of fossil fuels, alternative sources of energy have become important and relevant in today's world .Solar energy and wind energy are one of renewable energies, and they are inexhaustible energy source which are available any where, also known as non conventional sources of energy.
They cause less emission and are clean and safe because of their non-discharge of carbon dioxide, oxides of sulphur and nitrogen (the major atmospheric pollutants), radioactive and thermal pollution they are viable sources of clean and limitless energy.
INTRODUCTION:
In our day-to-day life, we use energy for various purposes, yet it is one of the few things on the world, which has not significantly changed with the times non-renewable energy sources are still being used over the world when new innovations renewable sources could be used instead. One of such innovative system is to increase efficiency of the productions of energy renewable sources is WIND SOLAR HYBRID SYSTEM.
SOLAR ENERGY:
Solar energy utilization became predominant with the putting into practice of semiconductors. Solar energy can be trapped with so called Solar Cells. Though the solar cells are expensive, they never cause pollution. For sufficient power to be generated large number of solar cells must be used. The basic principle is photo electric effect.
• Solar photovoltaic power produced in India is 2.75 MW standing 5th in generation.
• There are as many as 54’795 solar street lightening systems, 0.342 million solar home lightening systems, 0.56 solar lanterns.
• The areas near the equator are best places to get more out of solar radiation.
• There are as many as twelve solar power projects in India. As they are expensive their establishment is limited to the economic conditions of a nation. Satellites use solar energy only as it is the best means for working energy.
WORKING:
During day, solar radiations gets converted into DC electrical energy using solar photovoltaic modulus while aero generators (small wind energy conversion system) Exeter on the mast converts Kinetic energy in the wind stream into mechanical energy and subsequently to electrical energy, the aero generator generates 3 phase AC power that is converted to DC using converters, the energy meter displays power consumed by gadgets. Necessary precautions are taken to protect the aero generator from damage due to excessive wind speed. The electrical energy generated is stored in the batteries and with the use of inverters (DC to AC conversion systems). AC appliances like lights, farms, pumps, computers etc., can be operated.
CONCLUSION:
• Taking into account the efficiency and effect on
• Environment, newer fuels must be discovered and machinery must be perfectly designed.
• Learn and let people learn the need of non-conventional energy sources and proper management without wastage. Use vehicles running with fuel cell or bio-fuel.
• Make the objectives of the 10th five-year plan successful with respect to the energy sources. The entire fund from the side of Government must be properly utilized. Promote the usage of non-conventional energy. Help build such energy plants.
Apart from advancement in Science and Technology we have the basic duty of protecting the environment.
