Energy is a big deal. We need it in every aspect of our lives in various forms, like chemical energy from food, electrical energy from power plants, heat energy from fuels to run vehicles, etc. If you look at the current stats, you’ll know the demand for electricity consumption is on rising. And as per EIA, the world’s energy consumption demand is expected to increase by 48% before 2040. The matter demands attention because it will raise the risk of energy scarcity and degrade the environment also. So, energy management, which is defined as the process or steps involving the optimization of energy use for its best possible outcomes and taking steps for its conservation, holds key importance in today’s times. And to save energy inside our homes, adopting a Home Energy Management System can help achieve our goals. This article will focus on how and how many benefits or savings a Home Energy Management System (HEMS) can bring.
What is Home Energy Management System (HEMS)?
The Home Energy Management(or monitoring) System (HEMS) is defined as a system consisting of hardware and software connected with each other to allow a user to monitor and control the energy use inside a household. To simply put, this technology allows you to effectively manage the energy consumption of your home.
Savings from HEMS
Let’s look at how much we can save by using HEMS. Various products come under home energy management systems (HEMS), which comprises the following:
A smart lighting system allows you to control the electric light (on/off) inside your home with the help of sensors and a microcontroller integrated with the light bulbs – LED or CFL. It also allows you to regulate the light intensity (to dim or to brighten) inside your home based on the intensity/amount of natural light coming inside your house. You may be surprised knowing that around 14% of your home electricity is due to lightings. So, taking steps to save in this area can bring substantial profits.
Smart appliances are, as they sound, smart enough, meaning they are capable of regulating their energy consumption based upon usage or requirement. Smart energy-efficient televisions and washing machines are 25% more efficient than conventional ones, while later is also 40% more water-efficient than the common washing machines. Many smart appliances allow you to integrate themselves with your smartphone device where you can view and regulate the energy consumption manually also from anywhere.
The Smart Thermostats are temperature controlling/regulating devices that can help to regulate your HVAC system. Given that HVAC systems are responsible for (almost)half of the total electric energy consumption inside a building, using smart thermostats can save a lot of energy and thus money for you. As per available stats, you can save electricity between 2% to 16%! and gas savings between (8-12)%.
Similarly, with smart plugs, you can save electricity between 1% to 4.58%. If you are hearing about these devices for the first time, then smart plugs energy saving devices that act as a proxy between an energy source and energy consumption appliance. They come affordable and handy, can transform a conventional appliance into a smart energy-efficient device within minutes, making them one of the really cool devices to have inside your home!
Various Home energy management products here are connected to an Energy Portal device, such as a Smart Appliance or a Utility Meter, from where energy consumption can be monitored and regulated. Energy savings prompts can also be created and automation of those products can be achieved leading to their feasible use. As per data available, Energy Portals can save electricity consumption between 5.7% to 7.4% and gas savings between 5.7% to 13%.
This was a brief on the energy savings that can be achieved through smart home energy management practices. As a matter of fact, you can achieve overall energy of (30 to 40)% if you transform your conventional house into a smart home. So, not only these initiatives will turn more economical in the long run, but they are also eco-friendly which will save our planet.
