" What is more, as costs for wind and solar power have plummeted over the past decade, and the new report points out that for a given amount of land, solar panels are at least 50 times more efficient than bio fuels at capturing the energy of sunlight in a useful form."
1. Wind and Solar do not complete with bio fuels. You can not run a truck, ship, or airliner on electricity effectively because of battery technology.. Even cars are limited today by cost. Now if you are talking about bio fuels to run generators then maybe, but for transportation not at all.
It is kind of like that big huge lie that people like to tell about wind and solar reducing our dependence on foreign oil.
