Not Clearly Pro or Con to the question "Can Alternative Energy Effectively Replace Fossil Fuels?"
"Natural gas can serve as a bridge fuel to a low-carbon, sustainable energy future. In particular, natural gas can provide the critical low-carbon 'firming' or back-up fuel that can enable deep market penetration of both wind power and concentrated solar thermal power. The marriage of gas and renewable energy in the form of hybrid wind-gas and solargas plants addresses the issue of renewable intermittency, greatly enabling low-cost/low emissions power generation...
The goal... would be to meet future electricity demand with efficiency in addition to wind, solar, geothermal, biomass, and other similar renewable sources as well as natural gas."
