Politics trumps logic
Unfortunately, the Senate (& compromise) versions got rid of the $2 billion to accelerate technologies and instead put in lots more $s (good news) for pet projects (bad news). It seems politicians think they can "pick winners" better than scientist, engineers and entrepreneurs. Can you say "ethanol"? When will it end?
House version: "$2,000,000,000 shall be for expenses necessary for energy efficiency and renewable energy research, development, demonstration and deployment activities, to accelerate the development of technologies..." (i.e., open-ended as to what might actually work!)
Compromise version: "That $2,000,000,000 shall be available for grants for the manufacturing of advanced batteries and components..." (i.e., Closed-ended: "Do thus and so.")
