If the price is right

It has long been a bone of contention that renewable energy is far from cost-effective, and that view has been borne out by a recent landmark study. A report from Parsons Brinckerhoff, ´Powering the Nation´, reveals that the cheapest power would come from either nuclear generation or combined-cycle gas turbines, which come in at as little as 0.06 per kW/hr, while the cheapest estimate for offshore wind is 0.15, with tidal energy even more expensive.
