food, energy, water nexus Flashcards
food energy water nexus
the relationship will always exist, but we need to lessen their dependence on eachother. freshwater is a very stressed resource, and climate change is not helping
-it takes water to produce energy, and takes energy to produce drinkable water
water and climate implications
-increased water usage
-lessened freshwater availability and accessibility
-people dont live where accesible freshwater is
implications of the us as the largest food exporter and water implications of this role
-threatened by the water usage rate
-weak regulations and climate change of increased water usage
-leakage is a huge player
-thermoelectric power plants use a lot
- water is not used in solar
-fracking devours groundwater
hydropower advantages
-role in smaller countries
- emmissions free and renewable base load
-storage capacity
-flood control
how can we increase the role of hydropower
-pumped storage hydropower facilities
-new facilities in untapped waterways
-upgrading non power dams
-upgrades at existing facilities
barriers (and addressing them) for hyrdopower
-climate is the achilles heel
-r and d needed for non power dams
-extending awareness
-classification changed needed to change it to “renewable”
-streamlining regulatory licensing and permitting procedures
pumped storage
best bulk energy storage method
-excess can be used for pumping water from low to high elevation resoviors
microhydro
-archmedian screw
-desalinization
How can we reduce the intensity of the food, energy, water, nexus
1) wind and solar power
2) carbon farming
3) precision ag
4) policy changes
5) drip irrigation and indoor ag
-also reduces energy and water usage
