Which Renewable Energies Do We Use Most and At What Cost?

Here is a very interesting interactive infographic that  enables you to compare various forms of renewable energies, including solar, geothermal, wind, and bio-mass.  The comparisons are based on cost and the percentage of energy actually provided, compared to all consumed energy.  From the blog
In the U.S., only about 8 percent of all energy use comes from renewable sources. Petroleum is currently our largest consumed source of energy (37 percent), with natural gas (25 percent), coal (21 percent), nuclear power (9 percent) and renewables following behind.
