Energy policy to promote photovoltaic generation

Supplying present and future energy demand without adding to climate change is one of the most pressing problems today. Renewable energy is a potentially huge solution, for which governments are creating policies to encourage its harness and use. The dominance of photovoltaic (PV) among renewable energy technologies is owed mostly to its noiselessness, non-toxic emission, and relatively simple operation and maintenance. This study reviews the policies existing and in the making in seven leading countries that actively champion use of PV. (C) 2013 Elsevier Ltd. All rights reserved.
