What Is A Word For Energy Consuming?

This article will provide an overview of terms used to describe something that consumes a lot of energy. As energy costs continue to rise around the world, many people are looking for ways to reduce energy consumption in their homes and businesses. Understanding words that describe high energy usage can help identify opportunities to cut down on waste and become more energy efficient. This list of synonyms for “energy consuming” will equip readers with precise language to discuss energy consumption and conservation.

Energy Consumption

Energy consumption refers to the amount of energy used by individuals, organizations, or entire societies. It measures the total quantity of energy that is utilized for various purposes including transportation, electricity, heating, manufacturing, and more. Some common examples of high energy consumption activities include:

  • Driving gasoline-powered vehicles – Cars, trucks, and other modes of transportation that run on fossil fuels like gasoline or diesel consume large amounts of energy.
  • Heating and cooling buildings – Heating, ventilation, air conditioning (HVAC) systems use a lot of energy to maintain indoor climate control.
  • Operating appliances and electronics – Devices like refrigerators, ovens, computers, TVs, etc. constantly draw energy when turned on.
  • Industrial manufacturing – Factories and heavy machinery use immense amounts of energy for production and processing.
  • Commercial operations – Stores, offices, restaurants, hotels, and other businesses require energy for lighting, equipment, computing, etc.

In general, activities that involve the use of electricity, burning of fossil fuels, or converting energy into work will have high energy consumption. Reducing energy consumption is an important sustainability goal for many individuals, companies, and governments seeking to lower costs and environmental impact.

Energy Intensive

Energy intensive refers to processes, industries, or activities that require large amounts of energy per unit of output. Energy intensity is measured as the ratio of energy consumption to economic or physical output.

Some examples of energy intensive industries and activities include:

  • Steel manufacturing – Making steel is incredibly energy intensive, requiring huge amounts of electricity and heat.
  • Aluminum smelting – Extracting aluminum from bauxite ore uses massive amounts of electricity.
  • Cement production – Heating limestone to produce cement takes vast amounts of energy.
  • Plastics manufacturing – Making plastics and polymers is extremely energy intensive.
  • Data centers – The servers, cooling, and operations require enormous electricity use.
  • Cryptocurrency mining – Verifying blockchain transactions is computationally intensive.
  • Desalination – Removing salt from seawater to produce freshwater requires substantial energy.
  • Glass making – Melting silica sand into glass requires heating it to extremely high temperatures.

Any process or industry that consumes large amounts of energy relative to its outputs can be considered energy intensive. In general, manufacturing industries tend to be the most energy intensive sectors of the economy.

Energy Hog

The informal term “energy hog” refers to appliances, devices, or other things that consume a high amount of energy. An energy hog has an excessive appetite or demand for power. This slang phrase portrays energy-guzzling items as greedy, gluttonous animals that feed voraciously on electricity or fuel.

Common household energy hogs include old refrigerators, incandescent light bulbs, electric heaters, and low-efficiency washing machines or dryers. Televisions, game consoles, computers, and other electronics can also be energy hogs if left continuously plugged in. Inefficient building designs, such as poor insulation and air sealing, can turn an entire home into an energy hog.

Identifying and replacing energy hogs with more efficient technology is one of the fastest ways to reduce energy consumption. For example, swapping incandescent bulbs for LEDs, purchasing Energy Star certified appliances, and updating leaky windows are all ways to cut down on energy waste and eliminate hogging behavior. The term reminds us to be aware of power-hungry products and to make upgrades for better efficiency.

Power Hungry

The phrase “power hungry” is a metaphor commonly used to describe things that consume large amounts of energy. This metaphor likens high energy consumption to the hunger for power. Just as someone who is power hungry constantly craves more control and influence, something that is power hungry constantly demands more energy and power to function.

The term can apply to people, machines, buildings, cities, companies, or any entity that uses an exceptionally high amount of energy. For example, a factory that consumes enormous amounts of electricity to run its machinery around the clock could be described as power hungry. A fancy sports car with a huge engine that guzzles gasoline might also earn this label. In each case, the entity has a voracious, unsatisfiable appetite for energy.

When used in reference to people, the phrase power hungry indicates someone who is greedy and constantly seeking more authority and dominance over others. But in relation to inanimate objects, power hungry simply conveys exceptionally high energy demands. Calling something power hungry underscores how wastefully it consumes energy compared to alternatives. This helps emphasize the need for efficiency and moderation when it comes to energy usage.

Energy Guzzler

The slang term “energy guzzler” refers to devices, vehicles, appliances, or equipment that consume a large amount of energy. The phrase is used to describe things that have high energy demands and inefficient energy usage.

For example, an old refrigerator from the 1970s that is not Energy Star rated would be considered an “energy guzzler” because it uses significantly more electricity than a modern, energy-efficient model. In the automotive world, low mileage gas-guzzling SUVs and trucks are sometimes called “energy guzzlers” since they require a lot of fuel to operate.

The term “energy guzzler” is often used critically to highlight products or behaviors that are wasteful and inefficient when it comes to energy consumption. It evokes imagery of greedily drinking up or devouring energy at high speeds. Calling something an “energy guzzler” suggests excessive energy appetite and waste.

To avoid being an energy guzzler, consumers and industries are encouraged to seek out energy-efficient, green solutions that consume less power. This includes purchasing ENERGY STAR appliances, driving fuel-efficient vehicles, and utilizing renewable energy sources. The goal is to curb energy consumption and shift away from wasteful energy guzzling behaviors.

Energy Glutton

“Energy glutton” is an informal metaphor used to describe something that consumes a very high amount of energy. It paints the picture of someone who greedily and excessively eats or uses up energy without consideration for efficiency or conservation. The term is often applied to homes, buildings, appliances, vehicles, or processes that are considered to be wasteful in their energy usage.

Calling something an “energy glutton” suggests that its energy consumption is gratuitous and self-indulgent, rather than reasonable and necessary. It implies that energy is being used carelessly or selfishly, without regard for the greater good. An energy glutton is voracious and insatiable in its appetite for power. Just like a person who overeats rich foods to excess, an energy glutton overconsumes energy resources beyond what is required or sustainable.

Examples of things that may be referred to as energy gluttons include gas-guzzling vehicles, inefficient data centers, poorly insulated buildings, and outdated appliances. The energy glutton label serves to highlight products, behaviors, or systems that needlessly squander power and contribute to resource depletion and environmental issues. The term evokes imagery of faceless entities mindlessly devouring energy in a wasteful manner.

Calling out energy gluttons raises awareness about sustainable energy use and encourages more conscientious consumption. While “energy glutton” may seem like a harsh label, it can inspire people, companies, and organizations to rethink their energy footprints. The metaphor reminds us to use energy judiciously, not greedily, before our appetite depletes the planet’s limited energy resources.

Energy Drain

The phrase “energy drain” refers to objects, processes, or systems that consume or waste large amounts of energy, typically due to inefficient design or usage. For example, an older model refrigerator from the 1970s may be considered an “energy drain” because it uses significantly more electricity than a modern Energy Star-rated refrigerator. The older unit’s inefficient compressor, insulation, and sealing can waste hundreds of kilowatt-hours per year compared to a new model. Similarly, homes with poor insulation, leaky windows and doors, or outdated HVAC systems can be considered “energy drains” because they require much more power for heating and cooling compared to a well-insulated, air-sealed home.

In the industrial sector, older mechanical equipment like pumps, motors, and compressed air systems can be major “energy drains” if not properly maintained. The U.S. Department of Energy estimates these types of inefficient industrial systems cost manufacturers billions per year in wasted energy. Upgrading to modern, high-efficiency models can sharply reduce electricity consumption and costs. Inefficient data centers or server rooms with outdated hardware, poor cooling, and low utilization can also be labeled “energy drains.” Consolidating servers, virtualizing workloads, and installing updated cooling systems can cut data center energy use by 20-40%.

At the utility scale, aging coal and natural gas power plants that lack modern pollution controls and generate electricity at lower efficiencies than modern combined cycle plants can be considered “energy drains.” Retiring older plants and shifting generation to newer units reduces fossil fuel consumption and associated carbon dioxide emissions. Utilities can also install digital management systems and real-time optimization software to reduce energy waste systemwide.

In summary, the term “energy drain” is often used to highlight opportunities to improve efficiency and reduce energy waste through equipment upgrades, better practices, and strategic system improvements.

Energy Vampire

One clever term used to describe energy-consuming appliances and electronics is “energy vampire.” This metaphor likens devices that continue to draw power even when switched off or not in use to mythical vampires that feed off human energy.

Like vampires that suck blood while you sleep, energy vampires drain electricity from the grid and cost you money when not actively powering anything useful. These “phantom” energy losses can really add up over time.

Common household energy vampires include phone chargers, game consoles, printers, coffee makers and cable/satellite boxes. These devices drain standby power around the clock while plugged in and switched off. Other culprits are idle appliances like air conditioners and heated water beds.

To stop energy vampires from silently bleeding you dry, unplug or use power strips to completely cut off standby power. Replacing old electronics and appliances with ENERGY STAR models can also reduce phantom drain. We can take back control over our energy bills by hunting down hidden energy vampires in our homes.


In this article, we explored various terms and phrases used to describe high energy consumption, including:

  • Energy intensive
  • Energy hog
  • Power hungry
  • Energy guzzler
  • Energy glutton
  • Energy drain
  • Energy vampire

All of these vivid terms are used to characterize devices, systems, processes or behaviors that consume significant amounts of energy. High energy consumption not only leads to higher utility bills, but also strains energy grids and exacerbates environmental issues.

With global energy demand continuing to rise, it’s crucial that we pursue energy efficiency in our homes, transportation systems, industries and commercial buildings. Simple behavioural changes like turning off lights, utilizing energy savings modes on appliances, and upgrading to LED bulbs can greatly reduce energy waste. On a societal level, transitioning to renewable energy sources and investing in smart grid technologies will be key to creating a more sustainable energy future.

The terms we use to describe energy consumption can help raise awareness of wasteful behaviors and motivate reductions. But words must be met with meaningful action on energy efficiency in order to drive real change.
