Sustainability from renewable energy - Obtaining a bigger cost-benefit to reduce the carbon and other pollutants’ emissions is achieved by the decrease of the energy quantity applied in producing goods and the service provision. It means producing the same amount using less energy, renewable, primarily. For this reason, energy efficiency and renewable energy are two essential advances in order to create a sustainable future. This change in energy habits is beneficial for both producers and consumers. Global energy efficiency standards already produce better performing equipment for the cooling system and its engines. This fact can be noticed by consumers when they receive their electricity bills. More effective devices use less energy and generate less noise internally. With the development of better equipment, the demand for copper increases. Because it allows for greater electrical conductivity, copper is the metal of choice for wire and cable composition and is becoming increasingly attractive due to the economy it provides. Other metals available do not guarantee the same efficiency as copper, and many still require up to 20% more material. Electrical systems containing one ton of copper can reduce CO 2 emissions by between 100 and 7,500 tons less than other materials. The use of copper wires and cables in devices such as stand-by and shut-offs also saves energy. Given all the above aspects of energy efficiency, it can be concluded that people interested in saving money could be drawn to the creation of sustainable communities in which energy saving and energy management technologies still lead to the best climate balance. A sustainable future is essential for society, and renewable energy is one of the ways. In this direction, the introduction of new technologies around the world has grown. Between 2015 and 2035, global demand for solar and wind energy is expected to increase, and European countries, followed by China and North America, appear to be the ones with the highest growth rate. Since 2015, these regions have increased their investment in renewable energy between 5% and 10%. By 2035 solar energy is expected to account for 35% of India’s energy and 7% in China. Europe and China will have, respectively, 21% and 18% of power capacities wind based. Copper is essential for grounding systems in wind power technologies and for electric generators. In solar energy systems, this metal is very important due to its characteristics of electrical and thermal conductivity and high resistance. The widespread use of renewable energy technologies brings environmental benefits to society and provides numerous economic advantages.
