On my way to Asheville, North Carolina today, I looked over on the side of the interstate to see mile after mile of fields. However, one took me by surprise. It wasn’t full of cattle or hay, but rows and rows of shining metallic solar panels. These so-called solar farms and scattered across the country, producing comparatively small amounts of energy to power little businesses and communities.
Something very alluring, at least aesthetically, about solar energy is its infinite nature. The sunlight is producing absolutely massive amounts of energy: the energy is there, we just have to develop technology and infrastructure to harness it. We don’t have to go looking for deeply buried reserves of solar energy, it is abundant, free, carbon-neutral, and unlimited. We couldn’t ever use all the energy the sun is emitting.
Additionally, new advances like 360 degree panels are reshaping the way we harvest solar energy: making it more efficient, and therefore more affordable. Mirrors can also be used to reflect more light during different parts of the day onto solar panels to collect photons. Scientists are hard at work making panels more efficient (currently the best panels are still only 20% efficient) and more affordable. Some solar power is even created by using mirrors to make steam from water. Photovoltaic energy is difficult to capture, but worth the effort and money.
