How to Create Energy Flow Diagram in Microsoft Power BI

Have you ever tried visualizing the various energy paths in a system? You’ll know it’s challenging if you’ve done it before. Energy is a fundamental idea that powers our society, and understanding how it flows may be transformative in several categories, from energy policy development to industrial process optimization.

Here is where energy flow diagrams come into action. In this comprehensive article, we’ll take you on a tour through the intriguing world of energy flow diagrams, teaching you how to unlock insights, understand their significance, and construct and interpret them efficiently.

What is an Energy Flow Diagram?

Definition: An energy flow diagram is a data presentation that depicts the motion and change of energy inside a system. It’s like an illustrated map that takes you through the complicated path of energy, from its source to its varied uses and ultimate destruction.

These diagrams depict the flow of energy using arrows and lines, where the width of the lines indicates how much energy is being changed or transported. Consider it an animated flowchart that graphically depicts the energy paths.

Why Energy Flow Diagrams is important?

Energy flow diagrams are essential tools in many fields, and their significance cannot be emphasized. Here is why they matter:

Transparency in Complexity:

Energy systems can be highly complicated, with various sources, modifications, and endpoints. Energy flow diagrams reduce complexity, making it easier to understand the overall picture.

Formulation of Policy:

Governments as well as organizations use these diagrams for establishing policies regarding energy. They provide a visual representation of exactly how energy gets produced, dispersed, and consumed, which aids in making decisions about sustainable energy policies.

Process Optimization:

Energy flow diagrams are used by industries to maximize their processes, finding areas where energy utilization may be increased, resulting in cost savings and reduced environmental effects.

Education and communication:

Energy flow diagrams are fantastic teaching tools. They assist students and professionals in understanding energy systems and communicating complicated concepts.

Components of an Energy Flow Diagram 

To develop an energy flow diagram, it’s necessary to be familiar with the following fundamental components:

Source: The source is where energy emerges. It could refer to a natural resource such as sunlight, fossil fuels, or nuclear energy.

Transformation: Energy frequently transforms, such as converting from one kind of energy to another.

Distribution: Energy is delivered from its source to multiple terminals via grids or networks.

Consumption: Energy is eventually used, whether by industries, communities, or other sectors.

Losses: Energy is hardly completely effective. Some losses occur during conversion, distribution, or use. These losses are an important factor to be compensated for.

Energy Flow Diagram Examples

Example 1:

This rich information allows you to explore the complex landscape of energy distribution and consumption. The data, which is derived from a variety of sources including agricultural waste, other trash, marina algae, bioenergy import, nuclear reservations, and natural gas, provides facts about megawatt outputs and user consumption across diverse industries.

Witness the constantly changing interrelationship of bio-conversion and thermal generating processes, demonstrating the intricate route of energy from its source to its various applications in industries, HVAC systems, and domestic appliances.

Example 2:

The energy flow chart, a concise representation of energy transfers, stresses the importance of line thickness in determining energy magnitude. Examining the example chart, which depicts domestic power consumption, three primary categories emerge main source, rooms, and devices.

Swift study finds that the air conditioner, oven, and stove are the most energy-intensive gadgets, while the kitchen is the most energy-intensive room.

This concise overview identifies significant drivers of energy use, allowing for more informed choices to improve home energy efficiency. 

Types of Energy Flow Diagrams

Energy flow diagrams are classified into numerous categories, which include:

Sankey Diagrams are a sort of energy flow diagram in which arrows depict the flow of energy. The dimension of each arrow corresponds to the quantity of energy that is being transmitted. Sankey diagrams are often used to depict energy flows in a system, emphasizing productivity and losses at each step.

The Single Channel Energy Flow Model represents the flow of energy in an ecosystem across the food chain, with a single direction of motion from producers to consumers. It emphasizes the gradual decline in energy at all trophic levels as a result of cellular processes and energy losses.

The Double Channel or Y-Shaped Energy Flow Model illustrates the concurrent functioning of grazing and waste food chains in an ecosystem, demonstrating their connectivity.

The Universal Energy Flow Model is an extensive description of ecosystem trophic fluxes that may apply to any living element. It describes ecological productivity as the sum of organisms’ efficiencies in utilizing their food supplies and converting them into biomass for the next larger trophic level.

Such energy flow diagrams are utilized for illustrating energy flows in a variety of settings, involving national energy balances, regional energy flows, organizational energy management systems, and technical procedures.

Benefits of Energy Flow Diagram

Suppose that you possess energy flow statistics and want to tell a captivating data story to your audience.

The audience you are targeting could include political leaders, top management, and other significant stakeholders in the energy sector.

So, where should you start?

Selecting the proper chart for illustrating data can be one of the most difficult tasks to complete. You have to look for the most effective one.

Utilize the chart if you prefer clean, straightforward visualizations that match your data story perfectly.

The chart is probably the finest way to represent complicated information, such as energy flow.

This chart lets you communicate your story in a variety of ways, including: 

Pattern and Trend Analysis: Use the charts to visually represent the generation of energy, utilization, losses, and costs. If you evaluate the chart in comparison with old and new data, you may also determine it for prediction.

Discover Productivity and Efficiency: The primary goal of any visualization is to enable improvement in productivity and efficiency. Energy flow charts let your audience find the most productive and effective energy sources and consumption.

Improves Reporting: Storytelling with information in presentations is the most prominent application of data visualizations. A flow diagram enhances your report by presenting essential information in the most basic possible format. Your audience will not struggle to comprehend the important facts that form the foundation of your data story.

Encourages simplicity and clarity: As we have stated, the charts provide clarity and simplicity. If you utilize this graphic wisely, even non-technical audiences will be able to appreciate the data story.
