Answer:
Horizontal-axis (HAWT) pros
- It is more effective than vertical-axis turbines, usually, vertical-axis turbines are lower to the ground, so they can't utilize the higher wind speed that is found higher above sea level.
- Higher efficiency: every mechanical machine will always convert its fuel into useless energy, (i.e. sound energy). They can convert more wind power into electricity than VAWTs. This is due to the blades being perpendicular to the wind.
Cons
- Transportation: Due to the masts and blades being taller than VAWTs, its transportation can occasionally cost up to 25% of the equipment's price.
- They need a yaw control: A yaw system is the component that will be required for the direction of the rotor towards the wind.
Vertical-axis (VAWT) pros
- Unlike HAWTS, a yaw system is not a necessity, nor do they even need it.
- The turbines can be closer together.
- Cheaper: As they are not as elevated as their HAWT counterparts, they do not need as much money.
- Do not need to be pointy towards the wind: this benefit is most prominent in places where wind direction varies frequently.
Cons
- Decreased level of efficiency: In VAWTs, there will be more drag that will occur inside the blades when they rotate.
