(CNN) - The Obama administration stepped up its defense of the controversial $862 billion economic stimulus plan Tuesday, releasing an analysis which concludes that the measure is helping to spark major technological advances in energy production, among other things.
According to the analysis, the package's $100 billion "innovation" investment has helped put the United States on track to cut the cost of solar power by 50 percent in the next five years.
The report also predicts that the cost of electric vehicle batteries will drop 70 percent by 2015. The country's total capacity to generate renewable energy, it says, will double by 2012.
Additionally, the analysis says that medical investments funded by the Recovery Act will lower the cost of a personal human genome map to under $1,000 over the next five years - a development that could have significant ramifications for health care.
