A recent study finds that companies are setting aside a large chunk of their IT spending for green technology projects (BusinessWeek, March 5, 2009). Two out of three of the large companies surveyed by Deloitte said they have at least 5% of their IT budget earmarked for green IT projects. Suppose that the survey was based on 1,000 large companies.
