3. Our electrical infrastructure is very dependent on petroleum inputs.
7. If we start having electric supply disruptions, these disruptions are likely to start chain reactions of disruptions of other types.
8. While it is theoretically possible to get around a lot of oil shortage problems by building new infrastructure, as a practical matter this is not likely to work, because of timing, the enormity of the project, and our current financial problems.
