I am in Government IT. We are being informed, that rolling blackouts by 2010 will be a consistant problem for much of the aging power grid.

Many of us are trying to shift power hungry process to run at night to help with this upcoming problem.

Plus the power grid needs maintenance, being able to shut down portions of the grid at night for maitenance is absolutely necessary.

I think for electric at home cars to be trully successfull, we will need home power generation. The electric companies will get into the home fuel cell buisness. THey will glady rent you the unit for a nice monthly fee.
