Thing is, solar has been out there for decades and we're still not truly embracing it as viable energy technology in this country, and until we embrace it fully, it won't become mainstream. Besides that, a great majority of government officials are in the pocket of big oil, because they have the currency to flow way more than alternative energy companies. So, while oil is spilling throughout the Gulf, we still argue about why drilling should slow down. Fact of the matter is, we could have much cheaper solar energy if it was supported by the government, and the same scenario exists for electric cars.
Sorry, I'm ranting, but I invested in STP some time ago not just for profit, but for the feeling of investing in a company that was making responsible choices. Doesn't matter if our country isn't playing along.
