In part one of this two-part interview, Corporate Watchdog Radio co-hosts Francesca Rheannon and Bill Baue speak with Ron Pernick and Clint Wilder, co-authors of the new book, The Clean Tech Revolution: The Next Big Growth and Investment Opportunity. Pernick and Wilder, who helped define the clean tech industry in their work with the research and publishing firm Clean Edge, discuss how clean tech includes clean energy sources such as solar and wind but not so-called "clean" coal or nuclear, despite the fact that some environmentalists claim nukes can help solve climate change. Pernick and Wilder also explain the six Cs, or the major forces they identified that are driving the clean tech revolution. This week's conversation covers fours of the Cs (costs, capital, competition, and climate), saving the final two (China and consumers) for the second half of the interview next week.
