Avg score: 7% Most missed: “What is an example of storing wind power electro-chemically?”
Wind turbines are typically installed in groups called "farms". Onshore wind turbines can produce 2.5 to 3 MW of power, while offshore wind turbines can produce around 3.6 MW.  Wind energy can be stored using a variety of methods, including: Batteries: Batteries are a good option for wind turbines because they are efficient, durable, and have a long lifespan. They can store energy from production peaks and release it as heat or steam later. Batteries can supply electricity for 20 minutes, while slower-response batteries can supply less power for up to an hour. Compressed air energy storage... Show more
