Anything we do to remain alive on this planet comes with a carbon burden. The use of renewable energy comes with a carbon burden – photovoltaic cells and wind generators for domestic energy production consume energy in being manufactured, resulting in carbon dioxide emissions – renewable energy is NOT “zero” carbon!

Commercial wind farms require energy in their construction, as do the cables to transmit energy produced. The term “zero carbon” is incorrect and misleading. The correct term is “carbon neutral”, enabling the positives and negatives of the green equation for all construction to be taken into account.
