Offshore wind energy - potential for India
This paper attempts to analyze energy demand scenario, especially that of almost unlimited wind energy and highlight vast potential of offshore wind energy for India in territorial water along its long coastline. Challenges to exploit this potential, financial viability of such offshore energy projects, social, environmental, and other related issues are discussed in Indian context to serve as a useful tool for policymakers to allocate resources for detailed studies for estimation and its ultimate utilization to add to growing pool of renewable energy.
Wind Energy Potential In India With Its Different Aspects
This paper presents the wind power potential in India with a review of different aspects. Excessive use of fossil fuel created environmental degradation and major problems like global warming and different forms of pollution. Fossil fuels are in limited quantity and are depleting day by day. Such situation compelled the world to find the innovative solution to full fill the increasing energy demand. Development index of any country in terms of economic, industrial and social depends on how much energy being consumed. To fulfill such needs Indian government took great initiative towards non-conventional energy sources. Indian government set up a separate ministry for proper monitoring and functioning of renewable power sectors. Continuous efforts from the government toward renewable energy source drove the country to 5th position in the world. India is currently in 4th position in wind energy installed capacity. Indian government set to achieve 175 GW Power from renewable energy sources till 2022 out of which wind energy will contribute 60 GW.
Mathematical Modeling of Scour and Deposition
Electronic computers are opening up the field of sedimentation engineering by permitting the analysis of problems which heretofore have required too much time and effort. Movable stream bed profiles are being calculated in addition to water surface profiles. The initial gradation of sediment material in the stream bed may be prescribed to facilitate the calculation of an armor layer. This gradation is continually changed by the computer program in response to sediment particles being deposited on the stream bed and material on the stream bed being removed to satisfy transport capacity. Hydraulic sorting of sediment by grain size is accomodated. The stream bed does not have to be represented by a single grain size. Retardance of motion because of armor layer is calculated.
