Substitute one type of old dirty sunlight energy with a new clean type.
The cheapest and dirtiest source of energy is coal.
That cheap energy is old sunlight in the form of decayed plants compressed over millions of years (a so called fossil fuel, coal).
The future cheap energy is eight minute old sunlight. Estimates are that enough solar energy strikes the earth every day to provide the power the entire planet uses in a year.
Here is a link to the SOHO Satellite which monitors the sun.

Warning: this solar observation can become very addicting.
The technology to capture sunlight and convert it to electricity already exists. We have solar photovoltaics, like we install on the roofs of buildings, and CSP (Concentrated Solar Power) like utility companies are building.
Here are videos about both of these technologies:

As the scientist from the National Renewable Energy Laboratory says in the video about CSP, the hope is that America will invest in solar energy the way that Spain and other European countries are.
If a country were looking for a way to invest in economic security and energy security while stimulating a sagging economy, there is no better use of our money than to move from the cheap old sunlight (coal) to the cheap (once the collectors are installed, it is close to free) new sunlight.
