The United States' portion of the electrical grid in North America had a nameplate capacity of 1,280 GW [7] and produced 4,029 TWh [8] in 2023, using 34% of primary energy to do so. [9] The country is the second-largest producer and consumer of electricity, behind China. [ 4 ]
The energy systems language of systems ecology. The energy systems language, also referred to as energese, or energy circuit language, or generic systems symbols, is a modelling language used for composing energy flow diagrams in the field of systems ecology.
Energy flow is the flow of energy through living things within an ecosystem. [1] All living organisms can be organized into producers and consumers , and those producers and consumers can further be organized into a food chain .
The US Department of Energy's Lawrence Livermore Laboratory maintains a site of Sankey diagrams, including US energy flow and carbon flow. [8] Eurostat, the Statistical Office of the European Union, has developed an interactive Sankey web tool to visualise energy data by means of flow diagrams. [9] The tool allows the building and customisation ...
Most energy budget diagrams don't explicitly show the "atmospheric heat flow." This diagram makes that flow explicit to help one see that energy is being conserved. However, no details regarding the flow are available. In practice, it involves some mix of latent heat transport (water vapor movement), convection, and radiation heat transfer.
Maintaining an effective grid requires management of three different but related sets of flows – the flow of energy across the grid; the exchange of information about power flows and the equipment it moves across; and the flow of money between producers, marketers, transmission owners, buyers and others.
When combined to form systems diagrams, these symbols were considered by Odum and others to be the language of the macroscope which could portray generalized patterns of energy flow: "Describing such patterns and reducing ecosystem complexities to flows of energy, Odum believed, would permit discovery of general ecosystem principles."
The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power on the Texas Interconnection that supplies power to 26 million Texas customers – representing 90 percent of the state's electric load. [3] ERCOT is the first independent system operator (ISO) in the United States [4] and one of nine ISOs in North America. [5]
