Major reductions in the costs of renewable technologies for electricity generation such as solar PV, geothermal, and wind are expected during the period 2010 to 2025. Also, a subsidy limited in time would give countries a strong incentive to accelerate electrification and reach a level of energy consumption compatible with a high development level by the end date for the subsidy. By then, they could presumably assume the lower costs of national feed-in-tariffs with no or less need for assistance from the international community.
