Citizenship FOr A BeTTer TOMOrrOW, SAVe energY TODAY The energy on Earth is not in unlimited supply. Furthermore, energy can take plenty of time to regenerate. This certainly makes it essential to conserve energy. Energy conservation is achievable by using energy more efficiently and reducing the amount of service usage. Energy efficiency Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services. Using less energy has lots of benefits: you can save money and help the environment. A perfectly energy-efficient machine would convert all of the energy put into the machine to useful work. Improvements Improvements in energy efficiency are usually achieved by adopting a more efficient technology or production process or by applicating commonly accepted methods to reduce energy losses. For example, modern appliances, such as freezers, ovens, stoves, dishwashers, washing machines and dryers, R O 14 D W S Reducing energy use It is also seen as a solution to the problem of reducing greenhouse gas emissions. According to the International Energy Agency (IEA), improved energy efficiency in buildings, industrial processes and transportation could reduce the world s energy needs in 2050 by one third and help control global emissions of greenhouse gases. Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy and are high priorities in the sustainable energy hierarchy. currently: al momento twin pillar: colonna portante; pilastro read and choose the correct option. Energy Labelling In the European Union, many 1. everyday / daily / dairy products such as washing machines, refrigerators and cooking 2. devices / tools / appliances carry energy labels and have been designed to 3. require / meet / respect minimum energy efficiency standards. Energy labels help 4. user / consumers / clients choose energy efficient products. The labelling 5. requirements / requests / questions for individual product groups are currently created under the EU s Energy Labelling Directive, a process managed by the European 15 use significantly less energy than older appliances. Buildings are responsible for approximately 40% of energy consumption and 36% of CO2 emissions in the EU. Currently, about 35% of the EU s buildings are over 50 years old and almost 75% of building stock is energy inefficient. Therefore, the renovation of existing buildings has the potential to lead to significant energy savings, which could reduce the EU s total energy consumption by 5-6% and lower CO2 emissions by about 5%.
