Agriculture accounts for 70 percent of total global freshwater withdrawals.
Food production consumes 30 percent of total energy consumed globally.
Dams produce hydropower and store water for irrigation and urban uses.
Biofuels crops are grown for energy use.
Plants convert sunlight energy to chemical energy, the basis of all food chains.
Energy extraction operations use up and pollute farmland.
Global transportation of food is a major fossil fuel user.
The entire water cycle is powered by energy from the sun.
Fossil fuel extraction and transport is a large water user.
Hydrogen (from water) fuel cells provide a potential future energy source.
Irrigation withdraws and farm runoff pollutes groundwater.
Nutrient runoff from farmland causes eutrification
Water shortages and food shortages go hand in hand.
Climate change is altering precipitation patterns and therefore farmland.
Renewable energy like solar and wind turbines can work on productive farmland.
Water cooling at power plants warms local water systems.
Many LEDC are planning new hydro schemes to meet energy needs.
Access to water for food production is a past and future source of conflict in many regions.
