Grid Parity for Solar and Wind Energy

According to the Global Wind Energy Outlook published by the Global Wind Energy Council and Greenpeace International, wind power alone could supply as much as 19 percent of global electricity needs by 2030, and 30% by 2050, given policy support. The economics of wind and solar production are leading the way: see an overview of recent studies relating to grid parity of solar and wind energy, including the October report by Deutsche Bank analyst Vishal Shah, and a New York Times article. The Deutsche Bank report found that solar has already reached grid parity in the ten states that represent 90 % of U.S. solar electricity production. Wind continues to face community opposition, but a Health Canada study in November concludes that there is no evidence of a causal relationship between exposure to wind turbine noise and self-reported medical illnesses and health conditions.
