are they for real? Wood is so inefficient as fuel that shipping it over anything more than 500km (number taken out of my behind, but it is in the ballpark) takes more energy than is contained in it.

The only reason to do so is to end up with high value in "biofuels" category. Just for show.

Not wood, compressed wood pellets. Energy density seems to be between 50-80% of coal. And remember that fuel is only part of the total cost, especially if the formulas include health costs, pollution or carbon emissions.
