A hidden challenge for renewable energy, in terms of carbon reductions at least, is making sure your cure is not more damaging than your disease. Many types of renewable power plants, for example, contain large amounts of concrete and cement, the production of which involves significant greenhouse gas emissions.

The emissions involved in construction, from concrete or other sources, seem rarely to be included in calculations of the environmental benefit arising from renewable energy. Yet it is not inconceivable that a wasteful enough construction process might produce more carbon emissions than a project could save over its operating lifespan.
