Wind is an abundant natural resource on Earth that occurs as a result of the sun unevenly heating the surface of the planet. As hot air rises, cooler air moves in to fill the void. Wind has long served as a power source to humans, from powering ships across the sea to farmers relying on windmills to grind their grains and pump water. Today, we use wind turbines – both onshore and offshore – to generate electricity. To learn more, read 10 Incredible Facts about Wind Energy That Will Blow You Away
- Wind turbines are huge– an average turbine blade is about 200 ft long while turbine towers reach up to 295 ft tall on average, and they will likely get even bigger to produce more renewable power.
- Offshore wind could potentially generate 18 times the current global electricity demand. They can generate more electricity with fewer turbines and it frees up land for other purposes without impacting human or terrestrial wildlife activity.
- Despite being the world’s largest greenhouse gas emitter, China is also the world leader when it comes to wind energy, producing more than a third of global wind power generation and capacity. Its Gansu Wind Farm will eventually include 7,000 turbines producing 20GW of power.
- In the U.S., the first commercial-scale wind farms have been approved off the Massachusetts coastline. Another will be built in the Pacific Ocean lining the coast of California with a long-term plan in place to construct wind farms along nearly the entire US coastline.
Path to 100% Perspective:
To reach clean energy goals, renewable sources like solar and wind will need to provide the basis of all power generation in the future. However, both are dependent on environmental factors that could make them less reliable. Backup capabilities must be in place to succeed, like both short and long term battery storage. In addition, flexible power plants, capable of ramping up when needed, will need to be installed. Eventually, those plants will run on sustainable fuels that can be generated by excess solar and wind energy.
