Renewable energy debate
From Wikipedia, the free encyclopedia
Policy makers often debate the constraints and opportunities of renewable energy.

Renewable electricity production, from sources such as wind power and solar power, is sometimes criticized for being variable or intermittent. The International Energy Agency has stated that its significance depends on a range of factors, such as the penetration of the renewables concerned.[2]
There have been concerns relating to the visual and other impacts of some wind farms, with local residents sometimes fighting or blocking construction.[3] In the US, the Massachusetts Cape Wind project was delayed for years partly because of such concerns. Residents in other areas have been more positive, and there are community wind farm developments. According to a town councillor, the overwhelming majority of locals believe the Ardrossan Wind Farm in Scotland has enhanced the area.[4]
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.[5] New government spending, regulation and policies helped the industry weather the 2009 economic crisis better than many other sectors.[6]
The concerns about environmental impacts of renewable energy are presented by the proponents of theories like degrowth and steady-state economy as one of the proofs that for achieving sustainability technological methods are not enough and there is a need to limit consumption.[7]
