• The Alternative Energy Blog did a nice overview of the current state of alternative energy investing in European markets.

• And finally, in news that's now a bit dated (apologies), a recent study gave evidence that companies with strong environmental performance are given a higher valuation by investors, perhaps (slightly) signalling better exits and exit multiples for cleantech investments -- both in terms of IPOs and in terms of acquisitions by large, established companies moving in these directions.
