Any type of development has potential impacts on the environment. Even though renewable energy is a clean source of energy that does not produce carbon emissions, building windfarms in the sea can have both negative and positive impacts on the environment. Through its research projects COWRIE is helping us all to get a better understanding of these impacts. Using this new knowledge developers can build and operate their projects in a responsible and environmentally friendly way. Everyone can benefit from the positive aspects of renewable energy whilst knowing that the environment is not being harmed.
