Answer 1

Explanation

Initial Cost:

Nuclear power plants have the highest initial cost due to expensive construction, safety measures, and regulatory requirements.

Running Cost:

Hydroelectric power plants have the lowest running cost since they utilize the natural flow of water, requiring minimal fuel or operational expenses.

Comparison between different power plants:

Item	Nuclear Power Plant	Steam Power Plant	Hydro Power Plant	Gas & Diesel Power Plant
Site	These plants are located away from thickly populated areas to avoid radio-active pollution	Such plants are located at a place where a supply of water and coal is available, transportation facilities are adequate	Such plants are located where large reservoirs can be obtained by constructing a dam e.g. in hilly areas	Such plants can be located at any place because they require less space and a small quantity of water.
Capital Cost	The initial cost is the highest because of the huge investment in building a nuclear reactor. (But less than Hydro Plant)	The initial cost is lower than those of hydroelectric and nuclear power plants.	The initial cost is very high because of dam construction and excavation work	The initial cost is less as compared to other plants.
Operating Cost	Except for the hydroelectric plant, it has the minimum running cost because a small amount of fuel can produce a relatively large amount of power	Higher than hydroelectric and nuclear plants because of the re- requirement of the huge amount of coal.	Nil	Highest among all (except nuclear) plants because of the high price of diesel.
Cost of Fuel Transportation	Less clean than hydroelectric and diesel power plants.	Maximum because a huge amount of coal is transported to the plant site.	Nil	Cleaner than steam power and nuclear power plants.
Overall Efficiency	More efficient than the steam power station	Least efficient. Overall efficiency is about 25%.	Most efficient. Overall efficiency is about 85%	More efficient than a steam power station. Efficiency is about 35%.
Standby Losses	Fewer standby losses.	Maximum as the boiler remains in operation even when the turbine is not working.	No standby losses.	Fewer standby losses.
