The Journal of Power Sources recently published a study that suggested the energy grid can be 99.9% renewable by the year 2030, using a mixture of wind energy, solar energy, advanced energy storage technology, and a standby of fossil fuel. Using a model grid system with the energy potential estimated from weather data samples, the study estimated that the combination of solar and wind energy could cover demand with very few gaps, which is when fossil fuels would be used. The study notes, however, that the costs of maintaining a sparsely used fossil fuel generator could be too expensive. Could improved demand response remove the need and achieve the extra .1%?
