The study the article is talking about, is a possible solution to cover California’s solar energy glut problem, it is a case study. In trying to do that, it may create other problems, such as infrastructure to get people to charge their cars during the day while they work. This means employers must pay chargers at work, adding onto more costs onto the employee. Nighttime charging may be cheaper and more convenient, but remember, the study wants you to capture all the wonder solar power during the day, not use potential green house gases from natural gas at night. The more complexity, the more problems you have.
