Is that really a bad thing? The government stated it wanted to encourage green technology development. In anything as new as that industry, you're bound to have failures. The fact that there hasn't been any successes is a bigger problem I'd say.
Is a $10B loss in this time of excessive deficit and debt bad?
Absolutely.
They aren't successes because you can't force things in a free market. When it becomes economically viable and effective, it will happen. I hope that happens soon... but until it does...
In other words, it was artificial. Most of these companies weren't really doing development, but production of inferior products.
Take the Chevy Volt that was heavily pushed... it sucks... they barely sold any, things were a danger, etc. Sound like something you want to buy? Why not just buy a Smart Car if that's the market you are in? It's more economically viable, safe, reliable, etc. It's not quite as green, but at this point it is the best thing out there in that market.
If the government wants to pick winners (Goldman Sachs, GM) and losers (Bears Stern, Lehman Bros, or the backed losers such as the list I showed), it should do due diligence to ensure it is reasonable and has a good chance of success...
I'd rather if politicians only handled big picture economic items, instead of micromanaging to that level, personally. They don't have a great track record.
