How Much Energy Does a Hospital Use?

Hospitals are some of the largest energy users in the world, but they also represent one of the best opportunities for us to conserve energy.

It is well known that hospitals use a lot of electricity and other resources. However, this has not always been the case.

Hospitals used to be very efficient in their energy use, but over time they have become more reliant on technology that consumes more energy than it saves.

The good news is that there are many things we can do as consumers and citizens to help hospitals save money and cut back on their environmental impact.

Hospitals Are Energy Hogs

Hospitals use a lot of energy because they are large buildings with many people working in them and also because they need to keep the lights on for extended periods of time.

Medical care requires power and sometimes a lot more than the average user consumption because of everything that needs power.

Hospitals are also used for research, which requires long periods of uninterrupted power.

Why They Use So Much Energy

Hospitals are energy intensive for a number of reasons. First, hospitals tend to have a lot of equipment, lights and other energy-consuming devices that need to be plugged in at all times.

Second, hospitals typically operate 24/7—even on holidays—so the power needs are constant.

Third, most hospitals serve multiple purposes within their buildings:

  • Patient care
  • Research and teaching
  • Outpatient services like radiology and pathology labs
  • Inpatient beds
  • Birthing centres
  • Operating rooms
  • Pharmacies
  • Kitchens serving meals

And finally, there’s the size factor; many hospital buildings are very large, which means they require more energy to heat and cool.

Not only does a large building take more energy for heating and cooling purposes, but it also needs more lighting because there are more rooms with windows that need to be illuminated during daylight hours.

The same goes for healthcare innovation and equipment such as elevators or escalators within a building: you will use more power if your building contains multiple types of machinery rather than just one or two machines in each department.

Large hospitals also have a higher number of staff members per patient compared with smaller facilities since there are many specialized departments within larger facilities, such as operating rooms or intensive care units where patients receive specialized treatment from highly trained professionals—which require additional staffing levels.

What Hospitals Are Doing to Conserve Energy

Hospitals are using energy-efficient lighting, cooling systems and heating systems to help reduce the amount of energy they use:

  • Lighting: Hospitals are using LED lights in rooms and hallways that emit less heat than traditional incandescent bulbs. They are also using sensors to turn off lights when not needed, saving even more energy.
  • Heating and Cooling: When it comes to air conditioning, hospitals use energy-efficient chillers (or cooling towers) that run at lower temperatures and don’t require as much electricity compared to older systems.
  • Building Awareness: Hospitals have been encouraging staff members and visitors alike by providing information about how much their actions can impact hospital energy usage and by offering rewards programs for employees who take steps toward conservation efforts.

Conserving Energy Should Be a Priority for Us All

Everyone will likely need medical care at some point in their lives. Conserving energy in hospitals should be a priority for us all.

That’s why we need to save energy where we can to ensure that there is energy and power available when we truly need it most.

Some countries are forced to cut power, drastically affecting everything, including medical care.

Electricity is a basic requirement for medical providers; they need it to do their job; it’s that simple. So saving power where we can makes a big difference.


We all want our hospitals to be well-equipped and staffed, but we also want them to use energy wisely.

That’s why it’s essential to understand how much energy they use, why they use so much of it, and what hospitals are doing to reduce their carbon footprint.

This can help us all make better decisions about our own energy usage—and save money in the process.
