How do hydropower thermal power and wind power generate electricity

How Wind Power Works

The simplest possible wind-energy turbine consists of three crucial parts: Rotor blades - The blades are basically the sails of the system; in their simplest form, they act as barriers to the wind (more modern blade designs go beyond the barrier method). When the wind forces the blades to move, it has transferred some of its energy to the rotor.

How turbines work | Impulse and reaction turbines

The more energy there is in the air, the more power a wind turbine can make. It''s just like the water. The harder it''s hitting your hand, the more energy it has, so the more energy you could catch and turn into power. A wind turbine is built very high up in the air because the wind (the air) moves much faster there.
