Lots of advances have been made in solar energy, as we’ve reported recently. But solar energy may not be all dandelions and sunflowers, and there are worries not just about efficiency. Simple production capacity dictates that even if we wanted to, we couldn’t produce nearly enough to meet our current energy needs. A post by scienceblogger James Hrynyshyn over at the aptly named The Island of Doubt has some more information of solar pessimism.
Just like at that business seminar you attended, constructive criticism is best. These add a dose of realism and keep us from wondering in five years why we’re still being told we’re just around the corner from a breakthrough. As Mr. Hrynyshyn said, "Don’t get discouraged guys. Just keep plugging away…."
