How is the potential wind power output calculated for a specific site and turbine? (Formula) P=0.5 x p x Cp x v^3 x As p= 1.2kg/m^3 Cp= energy coefficient (.4-.5) v^3= meters per second (double wind speeds=8 fold in power) As=m^2 (area swept by blade) How can the social gap in renewable energy be overcome? Include more people in the conversation and what could be the benefit. Define « intermittent » for wind energy. Why is it a problem? Wind energy can be on/off dependin...
