I thank Ken Czepelka (Jan. 29 issue) for responding to my Jan. 22 letter, "The Solution." I don't personally argue with Ken on what he presented, but it's in conflict with Robert Bryce's 2008 book, "Gusher of Lies: The Dangerous Delusions of Energy Independence." Bryce deals extensively with the "solar" issue. In Chapter 16, "Solar, the 1 percent solution," he provides an analysis by Raymond James and Associates that solar power in residential applications costs $0.37 per Kilowatt-hour, nearly four times conventional sources! Simmons and Company International estimated that even a growth rate of 25 percent a year of solar power capacity would only provide about 1 percent of global electricity demand by year 2020 at a cost of $0.22-$0.84 per Kilowatt-hour. By 2030, the Energy Information Administration estimates that solar power will provide about five billion Kilowatt-hours of electricity to American consumers per year, a mere fraction (0.0015) of the 3,351 billion kilowatt-hours of electricity the agency expects from coal. It's true that the Sun is an unlimited source of power, but cloud cover is also unlimited and is a "killer drawback" according to Bryce, along with a lack of "high-density electrical storage." "Solar power can never be relied upon to provide large quantities of base load power."
