Which energy technology really is the most economical, cost-effective solution for the long term? And how do renewable technologies really stack up when compared to coal, gas and nuclear on cost? Gail Rajgor kicks off a new Renewable Energy Focus series by asking whether it is even possible to compare technologies on a truly like-for-like basis. And if so, what do we need to bear in mind?
