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.
Main Challenges for Designing a Off-Shore a Wind Farm in Mexico
This article describes the main challenges involved for designing and planning of an offshore wind farm in Mexico. First, a brief description of the site is made and analysis of the wind resource is made in a maritime location located in the municipality of Magallanes, Tabasco, which has high wind potential. Subsequently, based on the characterization of the wind data, the type and class of the wind turbine is determined based on the characterization of the wind data. Then, the optimal distribution of the wind turbines is determined and the annual energy production and the losses caused by the wake effect are estimated. Also, the main components of the off-shore wind farm infrastructure are described and a parametric study is carried out to estimate the Joule losses of submarine cables. Finally, an economic viability study of the off-shore wind farm is made and a comparison is made with an on-shore wind farm.
On estimation of the displacement in an earthquake source and of source dimensions
The study of an earthquakes mechanism is usually finished bythe determination of a fault piane and the direction of displacementalong it. In many aspects of geodynamics and seismology it wouldbe very important to estimate also the dimensions of a source and cliiefly— the magnitude of the displacement in it.This problem can be reduced to the comparing of fields of sfaticaistress before an earthquake and after it. The difference of energies ofthese two fields depends upon source properties in question; lience it ispossible to determine dimensions of the source and the displacementin it if the forni of the source and the difference of the energies be known.The energy difference can be found from observations on the seismicwaves energy.The idea of such an approach belongs to L. Knopoff. He solved thetwo — dimensionai problem which. deals with the study of very strongearthquakes with long faults. The analogica! three — dimensionaiproblem is considered in this paper; it is necessary for studying of morenumerous weaker earthquakes and investigation of some contiguousproblema.
