When I sort of looked down through some early lists of the stimulus package laundry list - I saw a lot of retro-fitting of buildings for energy efficiency in terms of a lot of the "green" dollars; particularly Federal buildings and facilities. This make a fair amount of sense for a variety of reasons. For example, converting from single to double paned windows soon pays for itself in many communities and there comes a time in which the upgrade actually saves more money than it cost to do in the first place. Still, it wasn't what I was expecting to see in terms of creating "green technologies" and "green jobs".
I can also see the advantage to upgrading the electrical grid so that we more efficiently use what we are currently generating. - Besides, if the energy efficient and petrol saving car of the future is electrically based, I can see a growing need at a rate that outstrips the doubled population within the next 25-50 years. - But, for the very little I've since read about the issue, what is proposed may cover about 1%-10% of the costs to honestly upgrade the grid.
With respect to some of these other projects - There are plans on the shelf and even permits issued for a number of these types of projects out there around the country. With the lack of Federal coordination, a number of communities and utilities have drawn up plans for their own back yards. I don't know that there is much for coordination between areas and regions about the country. I suspect that in the end, some areas, regions, and parts of the country are going to be light years behind others...Yet, these projects can meet a number of the Obama criteria and efforts.
