Still, it leaves the world with much less energy than during the good ol' cheap oil days... Too much less to provide me with much comfort...
According to
Dr. Steven Chu ...............
“But carbon-neutral energy sources are achievable.
A world population of 9 billion, the predicted peak in population,
could be fed with less than one third of the planet”s cultivable land area. Some of the rest could be dedicated to growing crops for energy. But the majority of all plant matter is cellulose—a solid, low-grade fuel about as futuristic as burning wood. If scientists can
convert cellulose into liquid fuels like ethanol, the world’s energy supply and storage problems could both be solved at a stroke.“
