The top five coolest ways to integrate renewable energy into the grid

Variability is not just some new phenomenon in grid management. What we found is that renewable energy is not fundamentally different. The criticisms of renewables often neglect the complementarities between different technologies and the way they can balance each other out if spread over certain regions and energy types. Grid operators are constantly working to balance available supply with demand -- it's what they do. There are always natural variations that cause spikes in demand, reductions in supply, or create disturbances in frequency and voltage. Once you see there are a variety of ways to properly manage that variability, you start whittling away at the argument that you always need storage or a megawatt of natural gas backup for every megawatt of renewable energy.
