I read your article ‘Face of Change’ (Interview, 12 February) with great interest.
Our overall aim must be to reduce CO2 emissions on a long-term basis. The perception of wind, biofuels and nuclear is that they produce cheap energy, free from fossil fuel CO2 emissions. But the vast amount of human and economic activity needed to create, erect, operate, maintain and dismantle these forms of energy, mean the collateral emissions are greater than those saved over the plant’s lifetime.
