This article contains the following exhibits: * Exhibit 1: Within three to seven years, solar energy's unsubsidized cost to end users will approach the cost of conventional electricity in a number of markets, including parts of the United States (California and the Southwest), as well as Italy, Japan, and Spain. * Exhibit 2: Installed global solar capacity will grow by roughly 30 to 35 percent a year, from 10 gigawatts today to about 200 gigawatts in 2020. -- ((Udhay Shankar N)) ((udhay @ pobox.com)) ((www.digeratus.com))
