More (solar) power to you

Remember when clean tech companies were all the rage and were going to save the world (and make investors a lot of money)? Well, that was before the credit crunch and when energy demand was surging. There was more than a whiff of the dotcom boom about the dizzying rise of clean tech stocks, and few were surprised when the sector came crashing down about a year ago. But unless everyone gives up on trying to stop climate change, the good clean tech companies will come back in fashion and will prove to be more resilient than many of the one-hit-wonder dotcoms. So now's the time to fill your boots, while shares are cheap. Buy solar power firm Romag.
