Waste (image) stays stocked in private until it's serviced, becoming a flow. This waste flow leads to either recycling plants, where it will become stock of plastic and glass pellets or recycled cardboard, or to cogeneration plants, where it transforms into a flow of electric energy. A beneficial change would be for these stocks to be more quickly converted into flows, and for these flows to be more recycling-oriented rather than co-generation, because burning also inputs undesirable flows into the system (particles, toxic elements, warehouse effect gases). Electricity: currently, most electricity in the country comes from nuclear plants and coal/natural gas plants. Renewable energies such as wind and hydropower are also important. To make the foreseeable increase in this flow sustainable, renewable sources such as solar will have to be complemented with local, networked stocks of electricity such as parked car batteries. Cars: the high amount of cars that flow in and out of Glasgow every day constitute a stock when they are parked in extensive car parks. A desirable future would see the stock reduced as a result of good public transportation, which in turn reduces the flows.
