CActivists say the southern North Sea will become the nation's "offshore powerhouse" with up to ten proposed wind farms.
Although activists are not opposed to renewable energy at sea, they fear that the building permit will be approved for other large onshore installations, as this is considered to be an essential power grid infrastructure.
Fiona Gilmore of SEAS, the Suffolk Energy Action Solutions group, said residents fear that large onshore facilities would be rash.
"We are fully committed to renewable offshore and wind energy, but the provision of this energy must be done responsibly to avoid unnecessary devastation," she said.
"Scottish Power Renewables [SPR] plans to build a concrete jungle on pristine coastal areas to land offshore wind energy and connect it to the grid.
"SPR has not been pressured to look for existing brownfield sites and there is no incentive for companies to develop infrastructure solutions for offshore wind power transmission.
"We need to be the world leader in delivering green energy, not just in terms of generating that energy, otherwise that energy will no longer be green."
SPR, one of several energy companies constructing wind farms in the southern North Sea, was not available for comment last night.
