    That's good to know.
    What about the environmental impacts of batteries?

    What about flywheel storage, or other types of mechanical energy storage? Is there hope to gain good efficiencies on these ideas?

    •  First, if you go to: (0+ / 0-) you'll see a link to a report that shows the relative costs of all storage devices, including flywheels, which are very inefficient, apparently.

      If you are talking lead acid batteries. Yuck. They have a very limited lifespan if actually drained down and recharged a lot and they create a huge hazardous mess when disposed of. New batteries? I don't know enough about.
