After a poor first half, renewable energy shares enjoyed a strong performance during July, with five of the eight cleantech indices that we track undergoing double-digit gains.
The best performer, up 15.9%, was the Ardour Solar Energy Index, which is heavily biased towards US solar stocks such as First Solar, Suntech Power and SunPower. Germany’s solar-heavy ÖkoDAX registered a comparatively smaller increase of 8.1%, although it had already seen a small gain in June as a result of optimism returning to the country’s solar sector.
