Eco Friendly Quick Definition: Embodied Energy
A seemingly perfect eco friendly product could have a naughty little secret……
When people see an eco friendly alternative, or a potentially eco friendly product – they might not always see the whole story – and this is where enbodied energy comes in to the picture.
Basically – there is a hidden trail of things that go into making anything – and this trail could hold some less than eco friendly pathways that you hadn't thought of before.
They aren't all bad though – they just need to be taken into consideration when weighing up one thing against the other – for example local grapes might use more energy to grow than South African grapes – even though they have used less energy to transport to market.
But to make all this easier to understand, let's look at what embodied energy really means: "…..the total energy used to create a product from scratch and then dispose of it after use".
However, when you really pick this apart it includes an awful lot of things – so lets look at those grapes now. So, we need to grow the grapes, pick them, pack them and get them to the shop – simple? Not very……

Embodied energy would include the following list of things:
1) Maintaining the vine since the last harvest – which includes feeding, watering, clipping, treating and possibly heating or covering throughout the winter – which includes all the creation of all the chemicals used from scratch, energy to pipe the water, energy to move people and products to and from the site, energy to dispose of waste products, energy to heat or create covers for plants and the energy to create and maintain the necessary tools for the job.
2) Harvesting the grapes – which includes transporting all the staff and equipment to and from the vines, including and refrigeration, storage and internal transport of the grapes once harvested. And the energy needed to dispose of all the waste created by this process.
3) Packing the grapes – which includes all the packaging needed to wrap and protect the grapes while they are moved through the packing process (and the energy needed to make all this packaging in the first place and the energy to package the packaging and transport it to the vineyard), energy to run the machines, conveyers, and storage facilities while stored and before transportation. And the energy needed to dispose of all the waste created by this process.
4) Transporting the grapes – which includes all the energy needed to chill and protect the grapes while they are in transit – this of course will include all the energy needed to fuel the transport from vineyard to warehouse and could include road, rail and ship or air freight (and of course all the energy needed to keep that transport in tip top condition for transporting the product in the first place!). You will also need to use a small amount of energy in all the paperwork that needs to be completed as the product changes hands and moves through countries.
And after they get to the warehouse – they may be repackaged and re-loaded onto other modes of transport to go to individual shops, and then are stored, protected, chilled and moved around the stores using yet more energy. And of course, all the energy needed to dispose of all the waste created by this process.
You then need to buy them from the shop – using the tills and bags and your car or bus for transport which of course are all made of energy – and then you use your fridge to chill them, your water to wash them and your electricity to dishwash your kitchenware and then your bin bags to dispose of the stalks and packaging (and the dustmen have to use energy in their vans to collect it!).
Is That All?
Now, obviously this is a very detailed story of a grape's embodied energy – but is very simplistic as there are many things that haven't even been calculated here! And who want's to have to think about all of that when choosing grapes for tea?
However, there are some very simple things you can think of when choosing between 2 or more products for their eco friendly qualities – and this is one of them.
By thinking of the processes that have gone into making each of the products, you can get a clearer picture of it's qualities.
So, yes, those local grapes did only travel 20 minutes down the road to your local market – but did they have to use tonnes of energy-rich fertilisers to maintain in a not-the-best-suited environment as well as megawatts of heating to keep them alive through the winter waiting for the next harvest!
Or is the energy of transporting those African grapes (which were grown in a perfect environment with no need for heating or treating) less overall?
So, the concept of embodied energy can switch many 'simple' ideas on their head – but it is itself a very difficult thing to put your finger on. As you can see from the breakdown above – there are so many factors that it may be near impossible to fully estimate!
But at least you know what it is now!
