How do you generate a lot of electricity from a wind turbine?

I know it’d generate more if it was a windy day etc. but what actually happens inside the turbine to create more electricity? and are there any other ways to generate electricity with a wind turbine? Thanks, Kyle:)

How would you calculate the theoretical power output of a Savonius wind turbine?

I built a small scale Savonius style wind turbine for a project. I can easily measure the power it puts out in a wind tunnel using a wattmeter, but how would I calculate the theoretical maximum power output? I want to use these two values to find the turbine’s efficiency. Thanks!
