Energy saving: not only economics, but also ecology
Electricity is a common good and in today`s world it`s taken for granted. However, from time to time, and especially during global crises such as the current one, we need to remind ourselves how precious the energy sources from which it is produced actually are. The fossil fuel reserves on Earth can meet the needs of our planet for another 50 to 100 years at the current level of exploitation.
The EU is taking decisive steps in both energy saving and environmental protection. In 2021, the energy label for electrical devices was changed, with significantly stricter efficiency criteria. Among the EU`s strategic priorities is the "Green Agreement", which envisions Europe becoming carbon neutral by 2050, halting further climate change and preserving clean air and water, healthy soil and biodiversity.Today`s cities are super-consumers and super-pollutants
Cities today consume more than two-thirds of the world`s energy and produce about 70% of global CO2 emissions. This is not surprising considering the population. The UN report estimates that by 2050, two-thirds of the world`s population will live in cities. All major cities are facing a double challenge: how to reduce consumption and environmental impact, while meeting the needs of a growing population?
Lighting also plays an important role in these issues. Estimates of the share of lighting in the total world electricity consumption range from 15 to 20%, and there is room for savings.How to save on lighting?
In Europe alone, there are around 2.3 billion conventional luminaires whose outdated technology prevents potentially large savings and leaves a large carbon footprint. By simply replacing outdated technologies such as incandescent fibers, sodium, metal halide and fluorescent light bulbs with LED lamps or light bulbs, power consumption can be reduced by 50-70%. Modern lighting with LED technology has a significantly longer lifespan than conventional sources, so less maintenance intervention is required, which reduces the number of field trips and the total cost of maintenance. All this significantly contributes to the reduction of environmental pollution and the reduction of the costs of cities, and with the increase of the satisfaction of citizens, tourists and all others who stay in the city temporarily or permanently.
LED lamps from Signify
, the world leader in lighting, cover all applications, from functional to decorative lighting. A wide range of specialized brands such as Philips, Color Kinetics, Interact, Dynalite and others offers solutions for all types of public and private projects.Smart and connected lighting - savings with additional benefits
Cities that are reconstructing their lighting systems should consider a number of other benefits that can be achieved by installing "smart" LED lighting. In addition to their basic function, lamps can also carry sensors and many other devices. The potential impact on the quality of life of citizens is immense, from safety improvement (cameras, sensors to detect gunshots) through health (meters of air pollution, noise, etc.) to mobility, using sensors to determine traffic density in combination with traffic light control system and other digital traffic signals.Solar lighting - clean and free energy
In locations that have a sufficient number of annual hours of sunshine, from an environmental point of view, the ideal solution is solar-powered lighting. It brings free electricity with minimal impact on the environment. Signify`s stand-alone solutions make it possible to illuminate even those areas that do not have access to the mains. For those who have a network, but still want to make big savings and become "greener", there are hybrid solutions that use and accumulate solar energy whenever it is available, and only take electricity from the network when needed.
Is it about time for the future?
An increase in number of residents forces cities to dispose of their resources more rationally. One of the major consumers of electricity is lighting, and many cities still have public lighting based on outdated conventional technologies. By replacing these lamps and / or light bulbs with modern LED lamps and high efficiency light bulbs, significant savings can be achieved. Additional benefits can be realized by using the existing electrical network and smart lights as the basis of a smart city. Since lamps, in addition to their basic role, can also be points where IoT sensors are placed, large data sets that they create can improve the quality of life of citizens. Solar lighting brings the cleanest and free energy, and can also be connected to a smart city system.
As far as technology is concerned, the future has already begun, and cities need to use it, achieve savings and become more sustainable, while increasing the quality of life of their citizens.
