Unit of measurement for energy
Joules or kWh(Kilowatt-hours)
The connection between 2 nodes
A link
How do companies charge energy use
By using Consumption charges and Time of use
An example of conversion of energy during a process or reaction.
A candle stores chemical energy and converts it into thermal and light energy, or a toaster converts electrical energy into thermal energy
What a Joule(J) represents
A Joule represents the amount of work done by a Newton that moves a direction one meter in the direction of the force
How energy is billed
By calculating your energy use(in kWh) and the cost per kWh(Usage charge), and by having a fixed daily cost of your energy use.
Purpose of a Sankey diagram
To visualize energy flow from one point to another
What does kWh stand for
Kilowatt-hour
Example of an input, output, and waste in a sankey diagram
Input-Electrical energy Output-Light energy Waste product-Thermal energy
Connects one point to another
Nodes
A unit of measurement that measures the rate at which energy is transferred/used
Watt(W)
How to Interpret a Sankey Diagram
By following the flow from the source node(start of the flow) to the target node(end of the flow)(and by identifing the branch that indicates the waste product)
