Question

Give three difference between thermal power and hydel power

Answer 1

In terms of initial cost of ther­mal power generating plants are much cheaper, but their maintenance costs are high and need more labor. Thus it is costly. But in Hydel Power, the initial cost of generating hydro-electric power is more costly but their maintenance costs are low and need much less labor. Thus it is comparatively much cheaper.

The generation of thermal power produces air pollution and dust pollution. Waste materials are detrimental to land and environment. But Hydro-electric power is a clean source of energy. It creates almost no pollution or waste materials which are detrimental to the environment.

The sources of thermal power are non-renewable resources. So, they are completely exhausted after use and cannot be renewed. But Hydel power is a flow resource. It is not exhausted after uses.

Answer 2

"Hydel power"_ it is generated by fast flowing water .2_ it uses renewable resources 3_ it does not cause any pollution 4_ intially its cost is high but later it becomes cheaper.. example : (Bhakra Nangal project.)

"THERMAL POWER" 1_ it is generated by using coal / petroleum and natural gas. 2_ it uses all no renewable resources 3_ it does cause pollution 4_ its cost is very high and its production is expensive example: ( Badarpur thermal plant of Delhi) HOPE IT WILL HELp:)
