How will President Obama's $825 billion plan to stimulate the economy work? It looks like it will create jobs for the people working on the projects. But how long will those jobs last and will they continue after the projects are over? And if there's something wrong with his plan, what would be a better alternative? I think that if these projects are investments that create revenue generating operations, they are worth doing -- especially if those revenues ultimately recoup the investment.

Here are some of the specific plan elements that I view as investments:

• Boost renewable energy supply. The plan seeks to double renewable energy generating capacity of over three years -- to power six million American homes. It would upgrade two million homes and 75% of all federal buildings to better protect against the heat and cold -- saving low-income homeowners $350 a year in utility costs and cutting government costs by $2 billion a year. It would also provide loan guarantees to boost the $100 billion in private sector investment in clean energy projects over three years.
• Upgrade 3,000 miles of transmission lines for a national electric grid to make more efficient use of energy.
• Build 1,300 waste-water projects which would provide an ongoing revenue source for cities and states and reduce the costs of cleaning up polluted water.
