1. Heat energy is produced by burning fossil fuel in a furnace or from the fission of uranium in nuclear or by hot gas in a gas-fired power station
No pollution.
Energy produced by nuclear power cannot be stored, it has to be used as soon as it is produced. This is done by producing steam from the thermal energy released and using this in a conventional power plant
cooling towers
No
A power station generator uses mechanical energy produced by the steam turbine.
The average efficiency of a nuclear power station is about 33%, measured as the ratio of power electric over power thermal.

in a power station, which usually converts chemical potential energy into electrical energy, which supplies potential difference and drives current.
Electricity
Inputs of a power station is the air inside it produced. :) But seriously: The input to a power station is the source of energy use to make electricity. This can be water, oil, gas, coal, nuclear. In less conventional terms, wind turbines and tidal schemes are 'power stations'.
Cruachan Power Station is a storage hydro-electric power station whereas a Normal Hydroelectric power station is produced and then used, no storage needed.
A hydro station.
No pollution.
Potential energy
Once you convert the solar energy to electrical energy, it makes no difference where it came from. Distribution of such energy is exactly the same, whether it came from solar energy, a nuclear power station, a tidal power station, a geothermal power station, etc.
Water energy is produced when you use the movement energy of running water to power a waterwheel. That waterwheel then powers a generator which makes electrical energy. Then the generator transfers that energy to the power station.
