Today in India use of non-conventional energy sources in on large scale but the sources are limited and costly and is effecting on Economy and environment of our country. So, it is necessary to move towards green technology. Renewable energy is energy generated from renewable sources, which are naturally replenished on a human timescale, such as sunlight, wind rain, tides, waves, and geothermal heat. At this time we need renewable energy instead of non-renewable energy. Because due to use of non-renewable sources emission of toxic gases as well as solid waste takes place, which is much more harmful to environment. So regarding all these points, it was observed that renewable energy sources are more eco-friendly than non-renewable energy sources. Renewable energy sources involve solar, wind, tidal and geothermal heat energy. The study on literature review of Solar Trough and Parabolic Concentrator is introduced in this paper. Solar trough has tendency to reflect all solar radiation at focus line and parabolic concentrator has tendency to reflect all solar radiation at focus point. These reflected sun radiations concentrate at one line in solar trough so we can also called is Line Focus Concentrator and if sun radiation concentrate at a point, then we can also called is Point Focus Concentrator. These concentrated sun radiation produces High Temperature at focus line/point, which is used for so many different application of solar energy. This Focus line concentrator and Focus point Concentrator used for cooking, water heating, steam generation, electric power generation in domestic as well as industrial field. The Solar Parabolic Trough is the best way to use solar energy efficiently and effectively due to its ability to convert large amount available solar energy into effective and convenient form of heat energy which can be used for various different applications.
