ALTERNATIVE POWER CSChE 2002 Student Conference • Alberta’s restructuring experience: • Fundamental principles behind restructuring are sound • Prices will stabilize with more generation coming on stream • Despite California, no one has stopped deregulating. In fact Ontario will move ahead in 2nd Quarter, 2002

ALTERNATIVE POWER CSChE 2002 Student Conference The amount of power available in the wind is determined by the equation: w = 1/2 r A v3 where w is power, r is air density, A is the rotor area, and v is the wind speed. Wind power is a measure of the energy available in the wind. It is a function of the cube (third power) of the wind speed. If the wind speed is doubled, power in the wind increases by a factor of eight (23). This relationship means that small differences in wind speed lead to large differences in power.
