Session 1: Food and energy ties technology and innovation potentials

 

Food and Energy Ties

Fosssil fuels are energy in stored sunlight

After Ice Ages Wild Grains BecameDomesticated from Anatolia and Other Regions

 

Until Industrial Revolution in 18th Century Energy Came from Wind, WaveWood or Muscle

Food is stored sunlight energy via photosynthesis, just as fossil fuel energy is stored sunlight

During 1700's Steam and coal surpassed wood as energy source as England was deforested

 

In 1798 Malthus postulated that population would outrun food, but to date technology has refuted that premis, despite energy food links

 

 

 

 

Ethanol from corn spurred by subsidies and incentives of 2003 Energy Act

.

Energy and food tied together by sun, photosynthesis, formation, growth, use

Hetch Hetch and Hoover Dam for California and Arizona Power and Irrigation

Central Valley Project for California Water and US Water Resources

 

Energy use supports food production that facilitates population growth and global warming

 

 

 

Petroleum and food prices more related to supply and demand than global warming

 

Petroleum supplies over 90% of transportation fuel, nearly 100% for motor vehicles

Carbon dioxide is small but significant greenhouse gas

 

Nuclear, solar, wind, wave, geothermal energy avoid carbon emission but are costlier than fossil fuel

Agriculture mechanization and productivity growth offset Malthus food predictions until 20 th century

 

Enormous financial flows from food and energy trade are growing rapidly with price rises
