If you've ever worked with renewable energy, you know that storage is a major stumbling block. Unlike with a coal-fired or natural gas power plant, you can't adjust hydropower energy, wind energy and solar energy production based on grid needs.
Producing enough energy for a given area probably means overproducing when grid demand is low. You're also likely underproducing when grid demand is high, meaning your green energy source still relies on fossil fuels to keep the grid powered.
Batteries are available, and battery tech has come a long way in the past few years. While suitable for a home solar system, however, these batteries are expensive and not practical for long-term or grid-level storage.
