The article says the world relies on fossil fuel for energy because it's cheaper. That's true. It doesn't mention that the world relies on it because it's reliable. It doesn't disappear for 6 months of the year, or stop producing for 3 out of 5 days or during peak demand periods. Make renewables cheaper and more reliable and they will replace fossil fuels in a snap. Cheaper is not enough if it doesn't do the job.
