I'm sure the pace will pick up a bit but the bottom line remains the same. They won't significantly impact the energy shortage we face in this country. Alternative energy production is mostly hype and this administration is the biggest purveyor of hype that I've ever seen. "Green" companies are going out of business right and left. All funded with tax payer money. Billions of dollars up in smoke. When the funding runs out the companies fold. Time and time again. Private industry will solve the problem when it's financially profitable and not the government. We just have to sit back and wait. The government can provide the tax incentives which would help but then they have to get out of the way and that just not going to happen any time soon. IMHO
