The company expects energy demand to grow at an average of about 1 % annually over the next three decades — faster than population but much slower than the global economy — with increasing efficiency and a gradual shift toward lower - emission energy sources: Gas increases faster than oil and by more BTUs in total, while coal grows for a while longer but then shrinks back to current levels.

Restoring open ocean plankton populations to known 1980 levels of health would not only annually sequester at minimum 3 ~ 4 billion tons of atmospheric CO2 (or half our global warming surplus today), it would regenerate tens of billions of tons of missing nourishment for fisheries, seabirds and marine mammals.
