In Baltimore, the 300 block of East 23 1/2 Street is getting patched up in time for winter. One economic stimulus program is paying to insulate 11 rental rowhouses, another is paying for furnaces and a third is covering the cost for reflective roofs to be installed by prison inmates in a job-training program.
 
The block is part of one of the biggest initiatives ever undertaken by the federal government, a nationwide push to improve the energy efficiency of buildings. But as the national unemployment rate crosses into the double digits and Republicans question the stimulus program's impact, the work on East 23 1/2 -- even with all of its activity -- has so far not produced a single job.
 
Nine months after Congress passed the $787 billion stimulus package, there is little tangible to show for one of its biggest single areas of investment, the $25 billion energy-efficiency effort. That points to one of the central tensions of President Obama's landmark stimulus package: His goal was to inject money quickly into the economy while at the same time laying the groundwork for his broader, transformational agenda on energy, education and health care.
 
Officials overseeing the energy-efficiency effort want to fundamentally alter the way the country uses energy. They are trying to craft initiatives that will produce real savings to build the case for continued private or public investment. And they are putting safeguards in place to avoid any spending scandals that could tarnish the effort.
