Power Plant Engineering

TECHNOLOGY (GREEK “TECHNOLOGIA”): It is a systematic treatment of practical or
industrial arts, applied sciences resulting in technical progress by the use of plants and machinery and
automation in industry, agriculture, transportation, human and social activities etc.
Technology is an applied science dealing with specific technical problems; Technology is con-
cerned with satisfying short term, mid term and long term needs of society and its members.
2.4 ENERGY TECHNOLOGY
The applied part of energy sciences for work and processes, useful to human society, nations and
individuals is called Energy Technology. Energy technologies deal with various primary energies, process-
ing, useful energies and associated plants and processes. The coverage including exploration, transpor-
tation, conversion, utilization.
Energy Technology is concerned with ‘demand’ for various forms of secondary energy (usable
energy) and the methods of ‘supply’. Various factors affecting the ‘demand’ and ‘supply’ are in the
scope of energy-technology.
Energy can be supplied via various alternative routes. e.g. We may burn wood or natural gas or
use electrical energy to obtain heat. Energy Technology deals with various alternatives. The energy
chains (routes) between various raw energies (primary energy resources) and final energy consumption
are analysed and compared to decide the suitable choice.
Energy Technologies deal with plants and processes involved in the energy transformation and
analysis of the useful energy (exergy) and worthless energy (anergy). Energy Technology includes study
of efficiencies and environmental aspects of various processes.
Energy technology deals with the complete energy route and its steps such as:
1. Exploration of energy resources; Discovery of new sources
2. Extraction or Tapping of Non-conventional or Growing of Bio-farms
3. Processing
4. Intermediate storage
5. Transportation/Transmission
6. Reprocessing
7. Intermediate storage
8. Distribution
9. Supply
10. Utilization, Conservation, Recycling.
In every step measurements in terms of standard units are involved.
The Energy Strategies include the long-term policies, short-term and mid-term planning, eco-
nomic planning, social and environmental aspects of various energy routes. These are analysed from the
perspectives of the world, region, nation, states, sub-regions, various economic sectors, communities
and individuals.
The energy science and technologies give a systematizea, qualitative and quantitative approach
to energy studies for the entire human society, to an individual and the environment with reference to
the, past, present and future.
The present and future standard of living, economy and environment are shaped by the Energy
Technologies.
