Fact Sheet: Energy Efficiency Concepts

"After all, what is energy efficiency? What are the limitations of using energy intensity to measure efficiency gains? What effects influence energy consumption?

Brazilian energy intensity has remained relatively stable over the last two decades, but if we exclude the effect of changes in the structure of the economy, with the ODEX indicator, we can see that the country became 21% more efficient between 2005 and 2020.

Brazil has low residential electricity consumption per capita compared to other countries. This does not necessarily indicate that the country is more efficient, but rather that there may still be significant growth in consumption.

When calculating the energy intensity from the total energy supply, instead of the final energy consumption, the efficiency of transformation on power plants and the renewability of electricity sector can impact the result.

The 'Energy Efficiency Concepts' Fact Sheet presents these and other answers."

05/05/2022 - ​Environmental air pollution generates relevant health problems that affect especially the portion of the population that lives in large urban centers. The World Health Organization (WHO, 2019) estimates that air pollution in cities and rural areas annually causes 4.2 million premature deaths worldwide (2016 data). This mortality is mainly due to exposure to particulate materials, small particles with a diameter of less than or equal to 2.5 micron (mm) (PM2.5), which are related to the occurrence of cardiovascular and respiratory diseases, as well as to several types of cancer
