Green Energy – Utilization and Barriers of Solar and Hydro Power Technologies

Conventional energy sources, the best functional drivers of economic development essentially depend on oil, coal, and natural gas. Though these conventional energy sources noticeably effect the escalation of economic progress, simultaneously they are proven to be more hazardous to the environment and human health. The alternative sources of energy like solar, wind, hydro, biomass, geothermal & others may not have a specific impact on climatic conditions. These Green energy sources capably meet 12% of the world's demand for energy. These highly resourceful green energy sources are initiated and advanced at present in the form of Green technology which is often referred to as eco-friendly clean technology. It is an emerging technology in fulfilling the requisites of future generation, without diminishing or damaging natural resources available on the earth. It employs pioneering techniques in sustainable development to create eco-friendly products. The inherent reason for considering the Green technology the best of all ecological approaches relies in its capability to impact humans in diverse areas for ex., environment, economic, and social. This paper presents extensive perspective of Solar and Hydro sources for Green technology, its challenges and opportunities in line with global endeavors and trends towards sustainable development. It also outlined broad spectrum of areas where Green technologies are emerging. It is assumed that the progress of Green technology will initiate global, sustainable and macro-economic powers that have an impact on societies, economies and a way of life in future.
