What is Energy Efficiency?

Efficient use of energy, sometimes simply referred to as energy efficiency, is the goal of reducing the amount of energy required to provide products and services, and can also reduce the effects of air pollution. For example, insulating a building allows it to use less heating and cooling energy to provide and maintain thermal comfort. Installing light-emitting diode (LED) bulbs, fluorescent lighting, or natural skylight windows reduces the amount of energy required to achieve the same level of illumination compared to using traditional incandescent bulbs. Improvements in energy efficiency are often achieved by adopting a more efficient technology or manufacturing process or by applying commonly accepted methods to reduce energy losses.

What are examples of energy efficiency?

Wherever energy is used, there is an opportunity to increase efficiency. Some products, such as energy-saving light bulbs, use less energy to produce the same amount of light. Other products do not use energy directly, but increase the overall efficiency and comfort of a home or building (such as thermal insulation or windows).

Light-emitting diode (LED) bulbs: A LED lamp, or LED bulb, is electrical lighting that produces light using light-emitting diodes (LEDs). LED lamps are significantly more efficient than equivalent incandescent lamps and can be significantly more efficient than most fluorescent lamps. The most efficient LED lamps on the market have an efficiency of 200 lumens per watt (Lm/W). Commercial LED lamps last many times longer than incandescent lamps.

Fluorescent lighting: A fluorescent lamp or fluorescent tube is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light, which then causes the phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than an incandescent lamp. The typical luminous efficiency of fluorescent lighting systems is 50-100 lumens per watt, several times the efficiency of incandescent bulbs with comparable light output. By comparison, the luminous efficacy of an incandescent bulb is only 16 lumens per watt.

Natural skylight windows: A skylight (sometimes called a skylight) is a light-transmitting structure or window, usually made of clear or translucent glass, that forms all or part of a building's roof area for the purpose of daylighting and ventilation. It includes skylights, skylights, unit skylights, tubular daylighting devices, curved glazing and custom skylights. Today, solar panels are added to these windows.

Windows: Energy-efficient windows are made of materials that reduce heat exchange and air leaks; this means you don't need much energy to heat or cool a space.

Insulation: Adding more insulation to the attic prevents the warm air inside from escaping in winter. In summer, it keeps the hot air out. With good insulation, you won't need to spend much energy to keep your home warm in the winter and cool in the summer.

Smart thermostats: Smart thermostats are Wi-Fi-enabled devices that learn from your temperature preferences and control heating and cooling in your home and automatically adjust to energy-saving temperatures while you're asleep or outdoors. They can help lower your energy bills by not spending money on heating or cooling an empty house.

Computer power management: Computers can be set to automatically enter a low-power "sleep" mode when not in use.

Why is energy efficiency important?

There are many motivations to increase energy efficiency. Reducing energy use reduces energy costs and can result in financial cost savings for consumers if the energy savings offset any additional costs of implementing an energy efficient technology. Reducing energy use is also seen as a solution to the problem of minimizing greenhouse gas emissions. Improved energy efficiency in buildings, industrial processes and transportation could reduce the world's energy needs by a third by 2050 and help control global greenhouse gas emissions, according to the International Energy Agency. Another important solution is the abolition of government-managed energy subsidies, which encourage high energy consumption and inefficient energy use in more than half of the world's countries.

Energy efficiency and renewable energy are said to be twin pillars of sustainable energy policy and high priorities in the sustainable energy hierarchy. In many countries, energy efficiency also appears to have a national security benefit as it can be used to reduce the level of energy imports from foreign countries and consume less energy.

Energy efficiency studies in Turkey

Turkey started a new transformation process with the Energy Efficiency Law that came into force in 2007. Within the scope of the Energy Efficiency Law; It is aimed to increase efficiency in the use of energy resources and energy in order to use energy effectively, to prevent energy waste, to alleviate the burden of energy costs on the economy and to protect the environment. After the Energy Efficiency Law came into force, a series of regulations and communiqués were issued to ensure the implementation of the law. Among the aforementioned regulations and communiqués; There are Regulations on Increasing Energy Efficiency in Transportation, Regulation on Energy Performance in Buildings, Regulation on Increasing Efficiency in the Use of Energy Resources and Energy.

Turkey's first energy efficiency action plan, National Energy Efficiency Action Plan (2017-2023), entered into force on 02/01/2018. With the implementation of 55 actions in 6 different sectors, it is expected to save 23.9 million tons of oil equivalent (MTEP) cumulatively, with an investment of USD 10.9 billion until 2023. This corresponds to a 14% reduction in Turkey's primary energy consumption in 2023. The expected savings until 2033 is 30.2 billion dollars.
