Not Clearly Pro or Con to the question "Can Alternative Energy Effectively Replace Fossil Fuels?"
"This huge increase in renewables, particularly wind, will require a substantial increase in the amount of money taken from consumers’ electricity bills to subsidise new wind farms through the Renewables Obligation (RO)... This currently amounts to £1 billion a year, an amount which will have to rise significantly to fund the construction and development of thousands of new turbines...
But what of wind’s performance as an energy provider? Wind generation does not provide a reliable supply of power. It must be ‘shadowed’ by baseload power stations such as nuclear and coal as it is intermittent. Over-reliance on it could lead to supply interruptions if the wind does not blow, blows too hard or does not blow where the wind farms are located. Importantly, such high-demand periods of cold and hot weather correspond to periods of low wind so overdependence on intermittent wind can actually increase carbon emissions as conventional power stations are required as back-up..."
