| dc.description.abstract | In any calculation of the world energy resources, the
finiteness of fossil fuel resources set the limits. Most
authorities are agreed that by the turn of the century there
could be a rapidly developing shortfall in the available
supply of fossil fuels. Though short term solutions can be
achieved by improved efficiency in the production,
conversion, distribution and utilization of existing energy
sources, it would be wrong to conserve energy at any price.
The only alternative is to ensure adequate energy supplies
for the future by the substitution of non-depletable
resources for depletable fossil fuels. This can be achieved
if existing engineering & economic resources are co-ordinated
and dedicated to the development of the new energy resources.
Prior to undertaking this venture, it is essential to grasp
the techno-economic implications of the development of any
renewable resource. Since the oil crisis of the seventies,
geothermal energy has emerged as a very promising new nondepletable
resource among several novel non-conventional
energy resources. There are about 113 hydrothermal systems
in India and Puga geothermal resource in the North-West
Himalayan region lying in the Leh district of Jammu and
Kashmir has been identified as the most potential for
multiple utilization such as power generation, space heating,
greenhousing and aquaculture. A cascaded model entitled
CAMPER is conceived and the system is evaluated with the help
i ■
of a number of techno-economic models in a three-tier mode of *
alternative scenarios. Geothermal energy resource
exploitation in Puga by cascaded application is both
technically feasible and economically viable.
Chapter I which is introductory describes the
ramifications of geothermal energy, the environmental
implications of its utilization, the location of geothermal
energy resources of India and the objectives of the study, in
addition to a profile of Puga where this study was done.
Chapter II analyses the technical systems for resource
extraction, power generation, space heating, greenhouse
construction, aquaculture and waste-reinjection. While
Chapter III develops the techno-economic models for
evaluation of the sub-systems, Chapter IV specifies the data.
Chapter V delineates the tools of techno-economic analysis
with the help of life cycle cost analysis, sensitivity
analysis and scenario comparisons besides a number of
computer programs written for the purpose. Chapter VI
presents the results of analyses module by module. Chapter
VII draws all the threads together to capture the main
findings of the techno-economic analysis | |
