One of the main impediments to harnessing solar energy is storage. Solar batteries work as a short-term solution, but not when it comes to long-term storage or to power, say, an entire city. Solar energy and oil wells might sound like an odd combination, but the principle is similar to how geothermal energy would be harnessed.
