Not Clearly Pro or Con to the question "Can Alternative Energy Effectively Replace Fossil Fuels?"
"Some argue that without subsidies clean energy could immediately displace fossil fuels. Unfortunately, that's a ways off. Clean energy still doesn't provide enough fuel and power to supplant fossil fuels altogether. It will take years, possibly decades, for clean energy to scale up enough to give fossil fuels a run for their money. We best get started."
