The problem of energy consumption in the modern world
Today, the issue of energy consumption is becoming increasingly relevant in Ukraine and around the world. With each passing year, the amount of consumed megawatts is growing. For example, in 2016 alone, global energy consumption increased by 2.5 times.
Threat to the environment
The problem of electricity consumption is becoming more serious, and specialists are trying to find solutions to this issue, taking environmental protection into account. Electricity generation is primarily carried out at nuclear and thermal power stations. One way to reduce electricity consumption is to modernize lighting systems. According to experts, creating one kilowatt of energy capacity requires spending between 1,000 to 3,000 dollars, whereas saving that kilowatt in lighting systems only requires spending up to 300 dollars.
Economic consequences of rising electricity prices
The rise in electricity prices has a negative impact on the economies of many countries. It is quite evident that in the near future, companies specializing in energy-saving technologies will hold leading positions in the market.
Modern lighting solutions
It is necessary to transition to lighting using semiconductor lighting devices in tunnels, underground passages, parks, and streets. This allows for energy savings immediately upon the launch of new equipment.
- LED lamps are one of the effective options. They consume approximately 4 watts of electricity and have a luminous efficiency of about 80 lumens per watt.
- In comparison, incandescent lamps have a luminous efficiency of only 10 lumens per watt, meaning they produce less light by 8 times.
The LED lamp market
In 2005, sales of LED lamps reached 4 billion dollars, and by 2010 they doubled. Cree company holds leading positions in the production of LED lamps. The new technology allows for receiving 100 lumens with a power consumption of just 1 watt.
Advantages of LED lamps
- Long lifespan – up to 10 years.
- An LED lamp can operate without maintenance for about 5 years, which is critically important for inaccessible places like street poles.
- Eco-friendliness: LED lamps do not harm the environment and can operate for extended periods on autonomous power supply.
Conclusion
Modernization of lighting systems is an effective way to save electricity. By replacing outdated incandescent lamps with LED ones, it is possible to significantly reduce costs not only on electricity but also on the maintenance of lighting devices. Many countries are already actively implementing LED lamps in various areas, including cities and private homes.
