Peter Drucker, known as the inventor of modern business management, is credited with saying:
“If you cannot measure it, you cannot improve it.” When making the most of the energy used in
your home or business, simply researching “energy efficiency improvements” often provides an
approximate idea of how a project’s energy savings compare to costs for improvement.
However, when opportunities are difficult to recognize, such as unexplained energy use or
calculating the amount of electricity produced by a solar panel array, an energy monitoring.
system is essential. In particular, those wanting to optimize their energy use need a system that.
specifically identifies where energy is used and how much is consumed over time, as well.

For those unfamiliar with energy monitoring systems, most consist of hardware, software and the
delivery of data to a smartphone, computer or other display device. Some systems allow.
additional components, such as smart plugs and thermostats, to be connected to provide.
automation of energy saving practices.
When choosing a system, consider the following factors.
Appliance recognition – Unless monitoring is performed on individual circuit breakers serving.
recognizable connections, the system must provide appliance recognition. Some do this through.
a process of machine learning by identifying the “signature” of an individual appliance’s energy
use and tracking it in real-time for further analysis.
Real-time cost tracking – Different systems will provide a variety of tracking reports ranging.
from daily to yearly. However, owners especially appreciate seeing the energy use impacts of
your appliances and devices in “real-time” and in terms of energy costs.
Smart devices – With the increasing popularity of “smart homes,” controlling appliances and
devices through smart devices is crucial. When using smart device applications, users expect to
be able to monitor real-time energy usage, adjust settings, set alarms and more. Systems without
apps still provide useful information to help save energy but don’t provide the level of
convenience many expect.
Solar energy capable – Many people have or are considering solar energy (photovoltaic)
installations for their home or business. Most often, these systems are integrated with utility.
connections so electricity can be used by the owner or flow back into the utility line. If the owner
requires more electricity than their solar panels are generating, the extra power flows from the
utility line. While most solar energy systems monitor and record how much energy they produce,
utility metering usually does not separately record how much is being used at the home or
business versus being put back on the line. For that reason, an energy monitoring system is vital.
to understand the breakdown of energy production and consumption.
Installation – Many systems are designed so Do-It-Yourselfers can complete installation. While
in the interests of safety, it is always better to have a licensed electrician appropriately handle the
job, doing so is an additional cost for consideration.
Cost and savings – Basic energy monitoring systems intended for use in residential or small.
business installations range from $70 to $450. According to the Natural Resources Defense
Council, the average owner identifies 10% energy savings after implementing new energy-saving.
projects. Some assertively pursuing efficiency optimization report savings as high as 20%.
