initial torque to overcome the friction in generator and then to keep constant speed of stator within the generator. Minimum 50NM

This all depends on firstly how the turbine is built, and how large the turbine is. Please add more detail.
Yes most power stations do use heat to generate electricity. Heat energy of the fuel (e.g. burning coal, burning oil, nuclear fission) is utilized to heat water present in the boiler. This heating generates steam, which is then utilized to run the turbine. However some power stations get the energy to generate electricity without using heat (e.g. hydroelectric dams, wind power, sea wave power, solar cell generation systems).
Hydroelectric energy is created by water powering a turbine.
Mini wind turbine
The minimum wind speed required to maintain motion in a wind turbine is typically around 3-5 meters per second (m/s). This is known as the cut-in speed, below which the turbine will not generate usable electricity.
5mph
Typically, wind turbines need a minimum wind speed of about 6-9 mph (3-4 m/s) to generate electricity. This is known as the cut-in speed. At this speed, the turbine blades start rotating and generating power.
Solar energy does not use a turbine to generate electricity. Solar panels convert sunlight directly into electricity through photovoltaic cells, without the need for a turbine.

One resource that doesn't use a turbine to generate electricity is solar power. Solar panels convert sunlight directly into electricity through photovoltaic cells without the need for a turbine.

To generate electricity from steam, a steam turbine is typically used. High-pressure steam is directed onto the turbine blades, causing the turbine to spin. The spinning turbine is connected to a generator, which converts the mechanical energy into electrical energy.
You don't. But you can use the weight of falling water to generate electricity. The water spins a turbine (a type of fan blade), and the spinning turbine turns an electric generator.
