But that's how I feel about the Vestas Consumer Wind study and its accompanying Corporate Renewable Energy Index, both available as PDF files from here.
The first study says that people like wind. Wind is popular. Wind has a halo effect, and this can be transferred to companies buying wind power.
This is a stupid business case. Invest in us so people will like you? Really? Really. No, invest in us because you will make money, at at least because you will advance a technology that can make money for you down the road. A business case based on PR is charity, not business.
