^{Renewable Energy & Emerging Technologies}

Meeting with the world wide expectation, renewable energy has evolved a lot. The use of renewable can be seen in day to day life basically in four areas electricity generation,  air and water heating and cooling transportation and rural(off-grid) energy services.  The existence of this energy has been find across wide geographical area as compared to other energy sources. Large application of renewable energy has resulted in significant improvement in energy security, climate change mitigation and economic benefits. The use of renewable energy has directed the people to move forward from conventional fuels due to the environmental reasons. Renewable energy can be defines as a form of energy derived from the natural sources which cannot be depleted such as wind or solar power. They are the natural energy present in all forms ranging from sunlight, wind, waves, geothermal heat and tides. There sources are replaced constantly but does not get short. Although there is unlimited supply of the fossil fuels, we should go for the use of renewable energy as it is not only safe for the environment, eco-friendly but also less prone to pollutants if any. The development in renewable technologies has led to human development both way rural and urban. A single form of renewable energy can be further converted into different forms. It won’t be wrong to say that renewable energy is leading to sustainable development.
