If anyone is interested, here is a back-of-the-envelope mass calculation:

Energy content of natural gas: 53.6MJ/kg=14.8kWh/kg Efficiency of combined cycle plant: ~50% Energy/Mass Ratio = 7.445kWh/kg

Mass of wind turbine: ~150 tons Max power: 1.5MW Capacity factor: 0.4 Lifespan: 25 years Energy/Mass Ratio = 876kWh/kg

Obviously refining the materials for a wind turbine requires more energy than making natural gas. Also obviously didn't include the mass of the natural gas plant itself. Also obviously natural gas leaks are very problematic for climate. Also obviously if only the blades are discarded (and these are typically a small percentage of the weight), you could imagine continuing to use the tower, nacelle, generator, etc...
