Nowadays, windmills don’t just rely on the wind’s force to push the blades into motion in order to produce energy. Modern turbines use more complicated and refined aerodynamic principles to make use of the wind’s energy most efficiently.
The two basic aerodynamic forces that work together in wind-turbine rotors are lift, which acts perpendicular to the direction of wind flow; and drag, which acts parallel to the direction of wind flow.
The blades of a turbine are shaped just like airplane wings, using an airfoil design. One surface of the blade is a little rounded, whereas the other side is quite flat.

Wind energy is one of the biggest source of renewable energy. In order to understand the working of the wind turbines, it is important to know about the different components of the wind turbine.
Although there are different types of wind turbines that operate, but the simplest possible wind-energy turbine consists of three major parts:
1. Rotor blades
The blades are the main part of the system. The blades act as barriers to the wind, although recent blade designs do more than just act as a barrier. As the wind forces the blades to move, the energy gets transferred to the rotor.

Welcome back to our 10 of the best series, counting through 10 of the greatest ways to generate cleaner, greener energy. Number 2 on our list, tidal power generators are a newbie to the circuit but with masses of potential yet to come!
Tidal energy is produced using tidal energy generators. This can be done in 2 ways; 1)Barrage generation, and, 2) tidal steam generators. Power created by the former is on the whole more environmentally friendly due to less impact on ecosystems. Like the wind turbine, the tidal stream generator rotates under water with the kinetic motions of the ocean tides harnessing the energy to produce electricity. Tidal power has huge potential due to the size of the oceans and predictability of the tides. Read the full story
