Abstract: Energy continues to be a major constraint in achieving socioeconomic growth in developing countries. Recent studies indicate that current patterns of energy consumption and anticipated growth of demand in developing countries risk becoming unsustainable in the long run and hence countries need to focus on sustainable energy strategies that do not impair their development goals. While the important role renewable sources of energy are destined to play in sustainable development strategies is well recognized by nearly all nations, the development and application of these sources on a wide scale face formidable technical, economic and social challenges. Major national and international efforts are needed to expand the use of renewable energy in order to ensure that future energy systems are sustainable from an environmental perspective. Such efforts are especially needed in building the requisite institutional capacity, decentralized infrastructure, human resource capabilities, technological and production capabilities and above all an enabling environment. The renewable energy development effort will have to assume a sufficient scale and magnitude if it is to serve as an instrument of economic growth and social progress. Renewable energy resources sector growth in India has been significant Even for the decentralized systems, the growth for solar home lighting systems has been 300%, solar lanterns 99% and solar photovoltaic water pumps 196%. This is a phenomenal growth in the renewable energy sector mainly for applications that were considered to be supplied only through major electricity utilities. Some large projects have been proposed, and a 35,000 km2 area of the Thar Desert has been set aside for solar power projects, sufficient to generate 700 to 2,100 gigawatts. Renewable energy systems are also being looked upon as a major application for electrification of 20,000 remote and unelectrified villages and all households in such villages and hamlets by 2012.

Energy is essential to our society to ensure our quality of life and to underpin all other elements of our economy. Renewable energy technologies offer the promise of clean, abundant energy gathered from self-renewing resources such as the sun, wind, earth, and plants. Virtually all regions of the world have renewable resources of one type or another. Wind, solar, biomass, and geothermal technologies are cost-effective today in an increasing number of markets, and are making important steps to broader commercialization. Each of the renewable energy technologies is in a different stage of research, development, and commercialization, and all have differences in current and future expected costs, current industrial base, resource availability, and potential impact on greenhouse gas emissions. This paper discusses the State Of The Art Renewable Energy and technology in its present scenario. Taking into account the general trends this paper discusses the different forms of renewable energy and their current trend and developmental status on the global arena mainly focussing India because it’s a country lying in the tropical region with abundant sources of renewable energy including a platform to utilize it to the best of its potential with the world class technology available in any other developing nation. Starting from the dawn to dusk this paper discusses the advent and state of the art of solar energy technology, geothermal energy technology, wind energy technology, biomass energy technology, hydropower technology and many more. It also discusses their environmental impact and many other aspects of sustainable development
