Renewables are no more natural, abundant, better or cheaper than fossil fuels, according to the Greening Earth Society (GES). The GES - an organisation which believes that "using fossil fuels to enable our economic activity is as natural as breathing" - claims in its report Renewable Energy and the Laws of Nature that the four tenets that form the basis of renewable energy's appeal to the environmental community are false. Author Mark P. Mills argues that renewable energy sources are no more 'natural' or abundant than fossil fuels, but are worse than fossil fuels because they require more intensive land-use, and are as inherently costly as deposits of coal or natural gas.
