[2] Wind turbines have some of the lowest global warming potential per unit of electricity generated: far less greenhouse gas is emitted than for the average unit of electricity, so wind power helps limit climate change. [3]However, there is a simple way of dealing with this problem – namely, the power output from a given type of turbine for different wind velocities can be measured experimentally – and the results can be stored in an easily accessible database. A known Internet tool of this kind is a Swiss Wind Turbine Power Calculator.
