As it pertains to storage, we're seeing growth, so yes, renewable energy has faced the issue of intermittency. However, generally speaking, grids face the issue of reliability as well.
Again, different sources provide different reliability solutions. When you think about demand, the question leads one to conclude that there must be a balance to this, which is the role of the grids. There are different technology mixes with each grid, the supply mix, so to say. We're implementing a larger strategy on storage to look at the whole grid benefit that it can provide to offset intermittency issues and reliability issues that are common to all grids and that are caused by all generation sources.
The addition of the investment tax credit or the extension of the investment tax credit to energy storage technology is wonderful, because it's creating solutions for grids and it's creating a domestic manufacturing capability as well.
