Hydro power works by flowing water pushing a water wheel that generates a power station to make power.
Are you out of your mind? A power plant generates electricity by spinning an armature in a field. The armature is spun by burning a fuel (Natural Gas, Oil or Coal) to make steam. Or in the case of a Hydro-electric power plant the force of water spins the turbine.
if you want to make a attractive and nice model it will cost around Rs.5000.
Depends entirely on the cost of the available energy source and the invested cost in the power plant. Most of our domestic energy in US is produced by Coal. Regulations to make coal more environmentally clean will drive up the cost.
Biomass energy comes from plants - such as wood waste, corn kernels or non food energy crops which are generally used to make liquid fuels, heat or electricity. The cost of energy produced from biomass always depends on the type of biomass that is being utilized, the type of energy being produced (heat, electricity or fuel), the technology used and the size of the plant. Power plants that can burn biomass directly can generate electricity at a cost of 7 to 9 cents per kilowatt-hour.
water
Hyrdo power is derived from the movement of water downhill, so the only way that hydro power could run out would be if water stopped flowing. That is a bigger problem than a lack of electricity. Of course while hydro power is renewable it is also finite (and comes with a cost to the environment). After all the possible avenues for getting hyro power has been exhausted the world will either have to make to without new energy sources or use the sources it does have more wisely.

Hydro Electric Dams, Geothermal, Wind Power
In hydro power the water from a dam is channeled through narrow down facing tunnels where it spins turbine wheels. These wheels axles are connected to electrical generators which make electricity.
