Re: will the size of the propeller in a wind turbine effect the energy produced

Yes, of course it will. The bigger it is, the more wind will affect it.

Moderator's note:
A search of the web will give you some great information about the relationship between turbine size and power generation. For example, the Danish Wind Industry Association has a great web site with lots of technical information and tutorials available. The American Wind Energy Association also has some great FAQs that can help. Good luck!
