4.3 Renewable energy GOAL: Deliver 30% of projected total electricity output from Renewable Energy Sources (RES) by 2015 and 60% by 2020 Preliminary findings show that several sources of renewable energy can be exploited at costs that are competitive with conventional power sources as long as no major investments have to be made for infrastructural improvements such as road construction or grid extension and reinforcement (e.g., generation costs for wind energy could be lower than EC$ 0.20/kWh, well below the current fuel acquisition cost of about ECS 0.28/kWh). For rehabilitation of the older hydro power plants, estimations show that
