Energy cheaper than from coalPublished on July 11th, 2010
When economic well-being measured by the gross domestic product exceeds a threshold, birthrate drops sharply.
Global warming now threatens irreversible climate damage, ending glacial water flows needed to sustain food production for hundreds of millions of people, and shrinking the polar cold water regions of the ocean where algae start the ocean food chain. Atmospheric CO2 dissolving into the ocean acidifies it, killing corals and stressing ocean life. Demand for biofuels increases destruction of CO2 absorbing forests and jungles.
Burning coal for power is the largest source of atmospheric CO2, which drives global warming. Airborne coal soot causes 24,000 annual deaths in the US and 400,000 in China. We seek alternatives such as burying CO2, or substituting wind, solar, and nuclear power.
