Renewable energy debate
There is a renewable energy debate about the constraints and opportunities associated with the use of renewable energy.Renewable electricity production, from sources such as wind power and solar power, is sometimes criticized for being variable or intermittent. However, the International Energy Agency has stated that this only applies to certain renewables, mainly wind and solar photovoltaics, and its significance depends on a range of factors, such as the penetration of the renewables concerned.There have been ""not in my back yard"" (NIMBY) concerns relating to the visual and other impacts of some wind farms, with local residents sometimes fighting or blocking construction. In the USA, the Massachusetts Cape Wind project was delayed for years partly because of aesthetic concerns. However, residents in other areas have been more positive and there are many examples of community wind farm developments. According to a town councillor, the overwhelming majority of locals believe that the Ardrossan Wind Farm in Scotland has enhanced the area.The market for renewable energy technologies has continued to grow. Climate change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable energy legislation, incentives and commercialization. New government spending, regulation and policies helped the industry weather the 2009 economic crisis better than many other sectors.
