The increase in climate change and global warming has necessitated other sustainable sources of energy such solar and wind. More recently, wind has become popular in the pursuit of replacing fossil fuels widely known to release toxic gases into the atmosphere.
IQS Directory reported that there are 35,000 wind turbines operation around the world to convert wind power into electricity. The working mechanism of wind turbines is quite simple as “a turbine’s blades spin clockwise, capturing energy. The main shaft is triggered to spin, which is connected to a gearbox within the nacelle. The gearbox directs the energy to a generator, converting it to electricity. The electricity then enters the power grid.”
The biggest wind turbines generate electricity worth 12 megawatt-hours in a year to supply 600 US homes, observed National Geographic. Because its operational cost is obtainable at no expense and wind is a clean source of energy—“Mass production and technology advances are making turbines cheaper.” In fact, several governments are drafting tax incentives to advance wind energy developments.
The following benefits obtained from wind energy spell out the chief reasons behind its heightened usage in recent years:
- Renewable source of energy
- Reduce electricity bills
- Feed-in-tariffs are imposed based on consumption, while excess can be exported to the local grid for a certain price
- Significant shrink on carbon footprint
- Store excess electricity in batteries
