As shown by an analysis by the International Energy Agency (IEA), with correct energy efficiency policies, the global economy could double in size by 2040. However, this is not what shows the latest data and events in the world. The truth is that there is a worrying slowdown in improving energy efficiency on a global scale.
Research done with companies promoting initiatives involving sustainability and energy efficiency have proven that economic return is highly significant. The bad news is that according to the American Council for an Energy-Efficient Economy, which assesses public policies and energy efficient business practices from the largest consumer nations , Brazil is still well below its potential.
The Brazilian energy matrix, for example, is still very dependent on hydroelectric plants. That is, a strong water crisis is enough reach the country for power generation to also be compromised and thus, cause economic and social problems.
What is missing is the population engaging and feeling the benefits of these changes and only then will it modify its behavior and become acquiring efficient equipment and making the rational use of Energy.
Even cities can implement programs in buildings, street lighting and basic sanitation and ensure a significant economy electricity. It may seem out of the ordinary, but if applied properly planned, energy efficiency can, yes, achieve these results of a only once.
