Even solar energy’s biggest fans are underestimating it

Every day, the sun’s rays send 173,000 terawatts of energy to Earth continuously, 10,000 times the amount used by all of humanity. Which is to say, the potential for solar energy is immense, and we’re nowhere near the limit.

That’s why solar energy is such an appealing prospect, particularly as an alternative to the fossil fuels that cause climate change. And over the past decade, solar energy technology has vastly improved in performance and plummeted in cost.

As a result, photovoltaic panels have cropped up like dandelions across fields and rooftops at a stunning pace. Yet even the people most plugged-in to the energy industry and most optimistic about solar power continue to underestimate it. In fact, it’s a long-running joke among energy nerds that forecasters keep predicting solar will level off as it continues to rocket up to the sun.
