The solar manufacturing industry is now a highly competitive industry. Solar module companies that can’t compete are dropping like icicles on a warm spring day. Shell dropped out of the solar module race in 2006, giving its solar business to SolarWorld.
Nonetheless, Shell is still quite bullish on solar energy in the long term. In one of the two future energy scenarios it just released (the New Lens Scenarios), it projected that solar would become the largest source of energy by 2070.
