Last year I put 29 solar panels on my roof, which should cover all of my electrical needs as measured at that time. More on this later.
Paul Krugman: “Wind and solar used to have a reputation as hippie-dippy stuff, not part of any serious approach to our energy future, and many people still have that perception. But it’s way out of date. The cost of wind power has dropped sharply – 30 percent in just the past five years, according to the International Energy Agency.
And solar panels are becoming cheaper and more efficient at a startling rate, reminiscent of the progress in microchips that underlies the information technology revolution. As a result, renewables account for essentially all recent growth in electricity generation capacity in advanced countries.”
