No, they got it right. Biofuel production is an extremely wasteful use of valuable land. Here is a comparison of projected algae-based biofuel production with CURRENT PV+BEV technology and current corn-based ethanol biofuels:GRA wrote:Considering we're less than 1/5th of the way through the 21st Century, I'd say their conclusion is far more decisive than is justified. It could well be true, or it could well not be. The next 10 or maybe 20 years, sure, if there are no major breakthroughs.
Current PV+BEV technology: 1,000,000 miles per acre per year
Projected future algae-based biofuel: 500,000 miles per acre per year
Current Ethanol+ICEV technology: 10,000 miles per acre per year
In addition, the PV is lightweight and can (and is) installed on top of buildings, so it does not use valuable farmland which could be used to grow food for growing fuel.
