Wind turbine noise averaged 4.5-9 dB louder than predictedAt 10 different facilities, acoustical engineers Robert Rand and Stephen Ambrose measured wind turbine noise to be 3-12 dB (average 4.5-9 dB) louder than had been predicted.
Annoyance from wind turbine noiseFrom Pedersen E, van den Berg F, Bakker R, Bouma J. Response to noise from modern wind farms in The Netherlands. Journal of the Acoustic Society of America 2009;126(2):634–43.
Wind-power generation does not correlate with demandWind-power generation (blue), insolation (gold), and power demand (red) time series data show wind energy's poor correlation with demand. Thirty days of data collected in April 2010 from Bonneville Power Administration are superimposed and normalized to their maximum values. Average values are in color-highlighted black lines.
