How Smart Homes Save Money and Energy

With the advent of digital assistants such as Alexa, Google, and Siri, technology makers have invented a new technology genre designed to give your home a brain. 

It’s called the smart home, and recent technological advances have enabled homeowners to take even more control over the systems inside their homes. 

From lighting to learning thermostats, the smart home means homeowners can do more to save money and energy. Smart home energy features can help reduce your energy consumption, which can, in turn, lower your utility bills. 

What Is a Smart Home?

A smart home is a home that is equipped with technology to automate and control various systems, such as lighting, heating, security, and entertainment. 

Using sensors and algorithms, a smart home can automatically adjust settings to optimize energy use. For example, a smart thermostat can learn your schedule and adjust the temperature accordingly, so you’re not heating or cooling an empty house. Smart lighting can also be controlled and scheduled, so lights are only available when needed.

The central feature of a smart home is usually a digital assistant device from Amazon, Google, or Apple. These devices allow you to access the features of your smart home by speaking an activation word and providing a command. 

For example, if you purchase an Amazon Echo device and a programmable thermostat, you can say, “Alexa, turn the temperature to 68 degrees.” If you have programmed the thermostat to communicate correctly with your Echo device, Alexa will change the temperature inside your home to 68 degrees. 

Homeowners can program dozens of other nifty gadgets to work with your digital assistants, such as smart bulbs, smart outlets, and even vacuum cleaners!

Do Smart Homes Save Electricity?

Yes! Smart homes have the potential to save energy by using automated systems to control lights, heating, and appliances.

If you’re wondering how to save money on electricity, smart thermostats can help. These thermostats can learn your daily routine and adjust the temperature in your home accordingly, ensuring that your heating and cooling systems are only running when needed. This thermostat control can help to reduce energy waste and lower energy bills.

Additionally, smart homes can use sensors and automation to control lights and appliances. For example, you can set your lights to turn off automatically when you leave the room, or you can use a smart plug to turn off devices that are not in use. Turning off devices can reduce the amount of energy wasted on standby power.

Another way that smart homes save energy is by giving you more control over your energy usage. With a smart home system, you can monitor your energy usage in real-time and adjust your habits to reduce overall energy consumption, including turning off lights when you leave a room or unplugging appliances when they are not in use.

How Does Smart Home Heating Work?

Smart home heating works by installing your programmable thermostat and programming it to communicate with your digital assistant. 

Depending on your programmable thermostat, you will likely need to download an accompanying app to program the heating and cooling, set a schedule, and configure any potential sensors that connect to the system. 

Once programmed, your smart home energy heating system will only work when it senses someone is home and adjust based on a programmed schedule.

Can Smart Heating Save Money?  

Yes! Like any programmable thermostat, the design of a smart home energy heating system will save you money by ensuring your HVAC system works on a timer or if anyone is home.

How Do Smart Lighting Systems Work?

Smart lighting systems use specialized light bulbs or fixtures that you can control remotely using a smartphone or other device. These light bulbs typically use Wi-Fi or Bluetooth to connect to a home network, allowing users to control the lights from a mobile app or other devices. 

Some smart lighting systems also use sensors and other technology to automatically adjust the lighting in a room based on factors such as the time of day, the presence of people, or the amount of natural light in the room.

Can Lighting Automation Save Money?

Yes! You can keep your lights off when no one is home by setting up your automation, so lights don’t activate unless instructed by a digital assistant or a motion sensor.

How Much Energy Can Smart Homes Save?

Smart homes can save a significant amount of energy by using energy-efficient devices and appliances and by automating specific processes to reduce energy consumption.

Smart appliances such as refrigerators and washing machines can be more energy-efficient than traditional appliances. However, the exact amount of energy that a smart home can save will depend on a variety of factors, including the size of the house and the type of devices and appliances that are used.

Are Smart Homes Eco-Friendly?  

Smart homes can be eco-friendly if they are designed and used in a way that promotes energy efficiency and conservation. The key to making a smart home eco-friendly is using technology to reduce energy consumption and waste. For example, devices and appliances marked with Energy Star are built to conserve energy. 

Can You Apply for an SEAI Grant?

Yes, you can apply for a grant from the Sustainable Energy Authority of Ireland for a smart home. The SEAI offers a range of assistance and support for homeowners who want to improve the energy efficiency of their homes, including grants for smart home technology. To see if you are eligible for a grant and to learn more about the application process, you should visit the SEAI website.


You’ll find the smart home at the crossroads of technology and homeownership. Never before have homeowners been given the level of control and scheduling offered by smart home devices. With energy efficiency and cost-savings at the forefront, smart home energy engineers are just one of the many brilliant minds trying to tackle energy efficiency in a world where energy use is under heavy scrutiny.
