The connection between grassroots making and fixing movements and innovation for low energy demand may not be immediately obvious. When thinking about energy demand and resource use it is reasonable to focus attention on immediate and intensive activities, such as heating homes or offices, or making energy-using products more efficient. However, if we think about the energy used to make and distribute the products used in those built environments perhaps links with making and fixing become less tenuous? Products ‘embody’ energy demand in terms of the resources required to mine, process, manufacture, and distribute them. As products break and become discarded, so further energy is demanded in the production of replacements.
Even relatively low energy using products like laptop computers attract criticism about the energy (and water) demands in their manufacture. The manufacture of microchips is energy intensive and has a material intensity in order of magnitude higher than ‘traditional’ products. With more products going digital, through the incorporation of smarter control systems, for example – and speculation about them communicating with one another and us via an ‘Internet of Things’ – then perhaps we need to think about embodied energy?
