This is an inspiring look at how new 'alternative energy' policies are leading the way in the fight against the global energy crisis. The looming threat of global warming may be the greatest long-term challenge of the modern age. "Switching to Solar" is an inspiring and optimistic story of a green revolution in the making, exploring how the unrelenting efforts of a small band of grassroots activists have discovered ways to turn solar into a practical retail energy solution. The crucial driver for the adoption of solar energy is not technology, but policy. Focusing on initiatives in Germany, it describes the use of 'feed-in tariffs' - where those producing excess energy from solar sell to energy companies - as the most successful mechanism for driving the widespread deployment of solar energy.
