Keep buying green bananas
Cautious Optimism is justified and healthy. However technological advances did not defuse the population bomb, only reset the clock
The continuing incremental progress in education and health care for Third World women and girls is the reason the population bomb did not explode. The birth rates of the 1960's would have extrapolated to 10-11 billion if the global cultural attitudes about women had not evolved. Even developed countries had not widely accepted contraceptive birth control until the late 60's. Birth rates dropped in developed western countries as well.
Economic opportunity was also a driver by reducing the number of children needed to support a family. Modern agricultural practices required fewer hands for higher yields.
It helped suppress population growth that China adopted a One-Child policy but on the other side; we have had no global wars, plagues or famines causing several millions of deaths during the past 50 years. The political actions probably are about a wash as to population control. Fewer people are born but more live longer. It does seem that plagues and famines may be on the upswing and will have a more significant impact in the future. Climate change driven crop failures from drought and flooding are predicted.
Can modern technical agriculture feed a few billion more people? Maybe, it depends upon the weather and 100 million tons of ammonia annually for fertilizer. Almost all that ammonia is produced from natural gas. The gas industry TV commercials optimistically assure me that North America has enough gas for 100 years at current usage. What if we double or triple usage to displace coal, fuel vehicles and augment agriculture? New pipelines and high prices until it is all gone . What then?

The definition of solar has been constrained latelly to mean PV, when it has long been inclusive. That inclusive definition is not going away.

Futura Solar has a multiple solar benefit roofing system that recognizes that inclusiveness. Intended for low profile commercial, industrial, agricultural and institutional buildings, this system takes advantage of the surface area of the roof to provide significant amounts of power to the processes taking place beneath that roof. This lowers the cost, and the emmissions, improves leverage vis-s-vis energy providers and insulates against price volatility.

David, great positive article, thanks very much for lightening up our doom days (currently very grey in Europe). Your reasoning is also very soundproof: we have continuously proven to beat negative and doom thinking, especially to proof illiterate politicians wrong (except for your champion Chu, who Americans should embrace and nurture!). There's still so much room for new additions to (partial) independence of fossil fuels: apart from sun (only starting), wind, geothermal (still only childplay efforts) we have incredible and unstoppable energy locked up in waves and tides. Just go on!

But, David, natural gas is a fossil fuel and in some ways of figuring dirtier than coal. The proposed transition to alternate energy is akin to the proposed use of heroin once to kick the opium habit.

The main problem is the emphasis on intermittent energy instead of baseload green energy. With geothermal, bananas are grown in Iceland while there are alligator farms in Idaho. The latter are commercial, the bananas could be.

Danes have even used the stench of pig farming to grow tomatoes through use of air filters.

Municipal sludge can power modern external combustion engines and Syracuse University has even experimented with use of powder biomass for an internal combustion engine.

Thank you for your optimism but we could do so much better far sooner if we only would. The threat of global warming is very real in my view and we seem to be losing the race.

Best, Terry
