2. Energy is one of the most vital elements for the existence of all living beings on the earth. The increasing demand for energy, gradual rise in oil prices, depletion of fossil fuels, unchecked deforestation and exponential population growth have aggravated the cooking energy problem. In this crucial situation, solar energy which is pollution free, cost free and available in abundance during most days of the year, offers a practical solution to the household energy problems. Solar cooker that works on solar energy is a great boon to both rural and urban households. It is a simple, safe and convenient way to cook food by consuming cost free fuel. According to some of the oldest scriptures of India, Rigveda and Brahma Grantha, Solar cooked food was called “Amritha” and the cooking appliance was known an “Akshayapatra”.

Among 98 percent of the respondents, 84 percent possessed box type solar cooker with single reflector followed by double reflectors. About 58 percent of the respondents purchased solar cooker in the price range of Rs2001 and above. Majority of the home makers (44%) purchased solar cooker in the last 5 to 10 years.

17. The major problem faced by the respondents while using solar cooker was its heavy weight, food could not be cooked whenever they wanted and that it took more time to cook food and food did not get cooked if the intensity of the sun was low. Respondents were satisfied with the advantages of solar cooker offered as a method of cooking. To combat this major drawback, there are solar cookers like the concentrating type, heat accumulating and steam cookers which are available in the market but the cost is higher when compared with that of the box type solar cooker. Solar cooker must be made available at a subsidized rate laying more stress on its advantages rather than disadvantages. Using solar energy for cooking at least one meal a day can save a lot of fuel, money and reduce environmental pollution. When we review today’s situation there is a lot of stress on alternative energy sources as it helps in combating the energy crisis and global warming to save our mother earth.
