There is a lot of power packed in our sun that all living things on earth depend upon. Humans have been able to capture some of the sun’s energy that falls to earth and convert it into usable power for a variety of practical uses like for cooking, heating, and to power everyday appliances.Solar energy is that produce by the Sun’s light- photovoltaic energy- and its warmth- solar thermal- for the generation of electricity or the production of heat, Inexhaustible and renewable, since it comes from the Sun, solar energy is harnessed using panels and mirrors. Photovoltaic solar cells convert sunlight directly into electricity by the so-called photovoltaic effect, by which certain materials are able to absorb photons (light particles) and liberate electrons ,generating an electric current. On the other hand, solar thermal collectors use panels or mirrors to absorb and concentrate the Sun’s heat, transferring it to a fluid and conducting it through pipes to use it in buildings and installations, and also for electricity production (solar thermoelectric). Solar energy is a major renewable energy source with the potential to meet many of the challenges facing the world. There are many reasons to promote its share in the energy market. This power source is increasing in popularity because it is versatile with many benefits to people and the environment. Solar energy offers many benefits that make it one of the most promising energy forms and proven it as the one of the most important source of energy. Renewable, non-polluting and available planet-wide, it contributes to sustainable development and job creation where it is installed. Renewable Inexhaustible Non-polluting Avoids global warming Reduces use of fossil fuels Reduces energy imports Generates local wealth and jobs Contributes to sustainable development It is modular and very versatile, adaptable to different situations Can be applied alike for large-scale electricity generation and on a small scale in areas isolated from the network

Renewable Energies are the most valued projects of our time and will be in the future and as we can see that today, we are much more aware of Renewable energies and its ways and means. Our Government constantly working on towards the generation, conservation, and promotion of more use of renewable energies.
We have Specific Ministry for the same named “Ministry Of New And Renewable Energy” (MNES) which is working as is the nodal Ministry of the Government of India for all matters relating to new and renewable energy. The broad aim of the Ministry is to develop and deploy new and renewable energy for supplementing the energy requirements of the country.
Creation CASE and Ministry:
Commission for Additional Sources of Energy (CASE) in 1981.
Department of Non-Conventional Energy Sources (DNES) in 1982.
Ministry of Non-Conventional Energy Sources (MNES) in 1992.
Ministry of Non-Conventional Energy Sources (MNES) renamed as Ministry of New and Renewable Energy (MNRE) in 2006.
The role of new and renewable energy has been assuming increasing significance in recent times with the growing concern for the country’s energy security. Energy self-sufficiency was identified as the major driver for new and renewable energy in the country in the wake of the two oil shocks of the 1970s. The sudden increase in the price of oil, uncertainties associated with its supply and the adverse impact on the balance of payments position led to the establishment of the Commission for Additional Sources of Energy in the Department of Science & Technology in March 1981. The Commission was charged with the responsibility of formulating policies and their implementation, programmes for the development of new and renewable energy apart from coordinating and intensifying R&D in the sector. In 1982, a new department, i.e., Department of Non-conventional Energy Sources (DNES), that incorporated CASE, was created in the then Ministry of Energy. In 1992, DNES became the Ministry of Non-conventional Energy Sources. In October 2006, the Ministry was re-christened as the Ministry of New and Renewable Energy.
If we talk about the Government body working on Renewable Energy in Rajasthan is Rajasthan Renewable Energy Corporation Limited (RRECL) which had been formed by merging erstwhile Rajasthan Energy Development agency (REDA) and the Rajasthan State Power Corporation Ltd. (RSPCL) in August 2002.

In the world of innovation and technology, it’s a bitter truth that it took a lot many years for humans to focus and work towards energies which we can recycle.
Today, we are at the edge of running out of our natural resources which have changed our priorities or left us with no choice than to shift to Renewable Energies. Still, a majority of the human race is still uneducated about the concept of Renewable Energies and its types, how it works?
Renewable energy is energy that is collected from renewable resources, which are naturally reloaded on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.
Renewable energy often provides energy in four important areas: electricity generation, air, and water heating/cooling, transportation, and rural (off-grid) energy services. Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries.
Talking about Solar Renewable Energy, it is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaic’s, solar thermal energy, solar architecture, molten salt power plants, and artificial photosynthesis.
It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favourable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
The large magnitude of solar energy available makes it a highly appealing source of electricity. Towards, which we have to work progressively so that we can better utilize our limited resources and start untiring our unlimited and create a bright future for our upcoming generations to live a resourceful life.
