Wind Energy
Wind Turbine Sizing Calculator
Find the minimum rated power needed for a wind turbine to meet your annual energy demand, given a site's expected capacity factor and system efficiency. Useful for homeowners, farmers, or project planners sizing a turbine before procurement.

Wind Energy
Wind Energy Density Calculator
Compute the wind power flux (watts per square meter) available at a site for a given wind speed and air density. This is the gross resource: the energy passing through every square meter of rotor area before any turbine extracts it.
