Water Energy Food to Think About Copyright @ Speaking Green Communications 2016 Renewable energy resources such as solar, wind and tidal are readily available and do not require fuel processing and associated water inputs The agri-food supply chain accounts for 30% of the world’s energy consumption and is the largest consumer of water resources, accounting for approximately 70% of all freshwater use.

Hinweis der Redaktion

  1. Good Morning. For those of you who do not know me my name is Tony Green and I would like share with you some insight into the Water Energy Food Nexus.
  2. If you would like to hear any more of these topics these are the topics have given presentations on. My website and social media would be the best way to stay up to date on my future events.
  3. Here is a brief overview of what I would like to share with you: I will discuss the intense water and energy requirements for the food we consume and I will touch on the effects of climate change which will require all of us to think about how we can reduce our water and energy footprints of the food to ensure sufficient resources are available for future generations. As the examples will show the water/energy/food connection are present in more things associated with our daily lives then you might think Any questions on what you would like to get out on today’s talk?
  4. 'A perfect storm'. These were the words of John Beddington, Chief Scientific Adviser to the British Government in 2009 when talking about the relationships between food, energy, water and the climate. For those of you who might not be aware - A nexus is an interconnection or a relationship My question is “what would lead to anyone something like that?” http://steps-centre.org/wp-content/uploads/Water-and-the-Nexus.pdf
  5. He was taking a look at the future which is summarized on this slide By the year 2030 ( Only 14 years away) in order to support the global population: We will need 50% Energy 50% More Food 30% More Fresh Water Where will this come from ?
  6. Summary of the Water Energy Food Nexus are as follows Climate change – less water, increasing drought and more volatility in rainfall will effect the availability of water 2. Energy intensity of farm operations – fossil fuels and GHG emission versus adoption of Renewable Energy Technologies 3. Water intensity of farm operations – irrigation Most water used for agriculture 4. Biofuel must not compete with food - Food for Energy Secondary methods generation to produce biofuel without using what could be used for food production. 5. Energy intensity of food transport – Transporting Food Especially in California with export so much of agriculture it produces Images: 1) Climate Change. 2) Water and Energy to Farm, 3) irrigation , 4) biofuel, 5) transportation Now I will delve into some of the particulars of Food with Energy and Water
  7. What I driving the demand for water energy and Food? A few things: 1. Rapid economic growth, (Money) 2. expanding populations - larger urban areas (People) 3. increasing prosperity (More Dollars for all) are ALL driving up demand for energy, water and food.
  8. Now I’d like to look at each of the three legs of the Water Energy Nexus Triangle. First I’ll start off with Water and Food
  9. Water in Food
  10. Now looking at the amount of water in our food Beef or Chicken which one takes more water to produce? The answer is Beef by a factor or 3 ½ Why? (Water to produce the food which feeds the cow)
  11. These foods have processes which are used to produce these products in large volume for our consumption As it turns out, the nature of these processes have a major impact on the water use or water footprint and energy use required to produce the product. Refers to everything on the menu.
  12. There are a wide variety of food processing operations involving a range of physical and chemical processes. They may be divided into four broad categories, however. Water: cleaning, Heating, chilling, freezing, boiling, fermentation (yeast) Energy: Heating, chilling, freezing, boiling, fermentation (yeast) , Ambient temperature processes. which includes cleaning and sorting; various size reduction processes - eg. peeling, chopping and shredding and milling; physical separations - filtration, centrifuging, expression, extraction and membrane processes; mixing, blending and forming. Thermal processes. These are processes involving heating and include pasteurization and sterilization; evaporation; and various cooking processes. Low temperature processes; chilling and freezing. Fermentation processes Note: when yeast is used water must be there to create an aqueous solution so that the yeast can move around and be able to freely come into contact with all the sugars Post processing operations; packaging and storage
  13. Here is a slide which discusses how much water is the fruit and vegetables we eat. These range for 96% at the highest to 79% at the lowest As you can see there is more water in all of these items than anything else.
  14. Water and Energy
  15. Before we get started what is Water Energy Nexus? Where have you heard the term? A Nexus refers to a connection The term Water-Energy nexus refers to the fact that water and energy are inseparable. This is because: Water is required to produce energy. Water is employed in the production of most forms of turbine generated electricity, either directly (hydropower, geothermal) or indirectly (washing, cooling). Energy is required to make use of water. Energy is needed to extract move, treat, deliver -use. and dispose of water This energy is primarily in the term of mechanical or electrical energy
  16. This image here shows examples of the connection and inseparably some of which we will touch on in more detail. In included in the drawing are: 1. Cooling Towers in Power Plants 2. Waste Water Treatment Plants 3. Dams 4. Mining 5. Pumping our Water The Red Flows are energy and the Blue Flows are water
  17. Here is a Overview of the Water Energy Nexus based on what is required to produce water and energy Add anything to add ?
  18. Finally I will cover Energy and Food
  19. Energy used in producing food, Energy used in transporting and processing food, Energy used to make packages for food Energy used by food retailers, Energy used by consumers in getting, storing and cooking food The following energy consuming processes are used in food *Processing *Agricultural Production *Disposal *Consumption – cooking *Retail – refrigeration during storage
  20. This gives a breakdown of the Energy Use by Process
  21. Energy from not only a process viewpoint but an equipment point of view
  22. This gives another view of the interplays. Water in the center which is where I think it should be
  23. Renewable energy resources such as solar, wind and tidal are readily available and do not require fuel processing and associated water inputs The agri-food supply chain accounts for 30% of the world’s energy consumption and is the largest consumer of water resources, accounting for approximately 70% of all freshwater use
  24. Getting your food locally goes a long way to reducing the water and energy footprints. When you Waste Food, you Waste Water as well as Energy. We as a planet need to manage these so that it will work for everyone.
  25. And with that I will take questions..
