Benefits Of Wind Energy

Since wind energy has so many distinctive advantages, it is both desirable and crucial to the world’s energy landscape. Four of these distinct benefits are as follows:

  • Wind turbines typically repay the lifetime carbon emissions associated with their deployment in less than a year before providing up to 30 years of virtually carbon-free electricity generation.
  • Wind energy provides tax revenue to communities that host projects. 
  • As it does not require any combustion process, it is an energy with low greenhouse gas (GEI) emissions, the main culprits of global warming.
  • Wind is an unlimited resource, and so is its use if there are sufficient air currents.
  • Its maintenance costs and cost per kW produced are both relatively low. The advantage is significantly greater where the wind blows more forcefully. 

What Are The Uses Of Wind Energy?

Let’s explore 10 uses of wind energy and why we should adopt it:

1. Free and Green: 

Wind energy is renewable and eco-friendly, leaving a zero-to-little carbon footprint as no fossil fuels are burned for its production. It contributes to reducing carbon emissions by millions of tons annually.

2. Off-Grid Electricity: 

Wind electricity generation offers a great solution for generating electricity in remote areas, including the countryside, mountains, and drought-prone regions.

3. Minimal Water Usage:

Wind power plants require very little water, helping conserve water resources. They produce no radioactive waste or greenhouse gases, aligning with global efforts to reduce pollution.

4. Space Efficiency: 

Wind power plants occupy less space compared to oilfields and petrochemical facilities. The land beneath wind turbines can still be used for agriculture and other purposes, reducing its environmental impact.

5. Drought Resilience: 

Wind power operates efficiently even in arid regions, assisting farmers and ranchers in pumping water to drought-affected areas and mitigating water scarcity.

6. Reduced Oil Dependency:

How Does Wind Power Work?

Wind power works on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. It operates by harnessing the kinetic energy of wind through wind turbines. Turbines often have two or three blades that function like helicopter rotor blades or airplane wings. When wind flows across these blades, it causes a decrease in air pressure on one side of the blade. This air pressure variation between the sides of the blades causes a lift and a drag. The lift has a stronger force than the drag, causing the rotor to spin. The rotor can have a shaft, gearbox, or direct-drive turbine connecting to the generator that produces AC electricity. Thus, the turbine system converts aerodynamic force into electricity.

How Is Wind Electricity Generated?

In its most common configuration, wind energy is generated when the rotor, which has three blades, rotates around a horizontal axis. The sweep diameter of these blades ranges from 80 to more than 200 meters. The longer the blades, the greater the electricity production capacity. As they rotate, the rotor drives a generator that produces electric energy. With conventional wind turbines, the electric generator requires a rotation speed of 1,000 to 2,000 rpm, whereas the blades turn more slowly (5 to 25 rpm). With these wind turbines, a multiplier (or gear box) is installed between the rotor and the generator to increase the rotation speed. More recently, direct-drive machines have been designed; with these, the generators operate with a variable rotation speed (5 to 2,000 rpm) and do not use a multiplier. The assembly is composed of the multiplier, and the generator forms the nacelle.
