The world is changing faster than ever. In the midst of the current climate- and energy crisis, there is an urgent call to bring in digital to make Danish Homes Energy Efficient.
A new urgency to rapidly bring down greenhouse gas emissions and reduce energy consumption has become the most important mission everywhere, from Denmark and across the World and from Industries and businesses to private homes. The situation is impacting all of us, our lives, families, businesses and I am deeply worried about how we are going to tackle it. However, at Schneider Electric we believe that the knowledge and technology to change the current situation, already exist today, ready to make a difference tomorrow.
The fastest route to Decarbonising Denmark is twofold; Make Energy Green through Electrification and reduce emissions through Digitalization and Energy Efficiency
Within Denmark the situation is no different, from what I see across Scandinavia and in my home country Germany. In Europe buildings account for 36% of the CO2 emissions, and Household’s account for approximately 30% – this is not much different for Denmark where 40% of the energy is used in buildings. This is because most of the final energy consumption in homes is covered by district heating, natural gas boilers or biomass – today approximately 700.000 homes in Denmark receives energy directly from fossil fuels or the burning of biomass, primarily wood pellet and electricity which is not yet 100% clean in Denmark. We have been living in an age of fire, however the current climate- and energy crisis calls for a new electric era – Electricity 4.0 – where the energy is electric and green covered by solar, wind or green hydrogen and energy efficiency is driven by digitalization.
Denmark can greatly benefit from electrifying its energy consumption. Today less than 20% of the energy in Denmark is electric, far less than neighboring countries. In a recent report from the Danish Ministry of Climate-, Energy- and Utilities 60% of Denmark’s emissions can be completely avoided by electrifying Denmark. This leaves us with a massive opportunity and obligation to make homes more sustainable and energy efficient.
Leveraging digital is the best solution to Energy Efficiency in Homes – Cutting up to 22% of your energy bill
When it comes to energy efficiency, although passive renovation solutions such as double-glazed windows and better insulation can help reduce consumption linked to space heating, only a fully digitized home can help optimize electricity usage linked to power hungry applications such as EV charging and electric cooking. Such a system is the answer to dynamic energy management for all types of homes and allows for end to end monitoring of consumption and carbon emissions at both appliance level and homes level.
Today, homes do not need to be Smart, they must be Sustainable and thereby Energy Efficiency. To many technologies are not made to bring energy efficiency into the home, but a sustainable and energy efficient home can still be smart. Through simple consumption insights from a Home Energy Management System, such as Wiser®, a home could save up to 22% in annual energy consumption. This is through a reduction of electricity by up to 15%, for example by reducing up to 90% of the standby power we have in our homes, as well as by utilizing digital thermostats which are connected to the Home Energy Management System. That’s good for the climate, for energy consumption and our private economy.
This translates into savings of approximately 9.000 kr. per annum per household. Consumption savings also lead to carbon emission savings, not at least here in Denmark where we have a low level of electrification in our society and where studies show the average Dane emits 2-3 ton of CO2 from the use of energy per person! If each of the 2.8 million homes in Denmark were to save the same amount, this would translate into carbon emission reduction of more than 6 million tons in a year.
In addition to energy and carbon emission savings, a digitized solution also opens new was of thinking about energy, it becomes visible, connected, smarter and more controlled. Energy monitoring and dynamic energy management helps to create awareness of consumption and emissions tracking, thus leading to a behavior shift towards power conservation.
Make your home future ready; make it Electric, Digital, and Sustainable
Home Energy Management Systems, such as Wiser®, play an even more important role in countries where utilities have imposed time of use tariffs and where homeowners have installed battery storage to power their homes with stored electricity when tariffs are high. The system does this by responding to price signals in real time. This mechanism also proves advantageous for utility companies as shifting demand from peak times to off-peak periods naturally reduces strain on the country’s electrical grid infrastructure.
Homeowners can further contribute positively to the environment by purchasing systems that have a low carbon footprint from the offset, for example Schneider Electrics Green Premium program, a program that commits to deliver superior sustainable performance through circular economy principles such as durability, upgradeability, and recyclability. Products that are green premium promise to deliver benefits for a longer duration of time and thus result in lower total cost of ownership as well as minimize any negative environmental impact.
Finally, Home Energy Management Systems makes homes future proof; ready for a world where micro grids and battery storage will soon become a reality and every home will need a digital system to seamlessly consume, store and sell clean energy. A system that delivers more and waste less – A system that helps us become more efficient.
It’s time to decarbonize Denmark. It’s time to evolve to a new electric world. It’s time for a change of mentality.
