Brazil's energy sector is transitioning towards electrification and green hydrogen, projected to infuse R$2.2 trillion into the economy by 2050. Lowered solar panel costs and an anticipated demand for additional photovoltaic systems point towards an energy evolution. Despite challenges, with right investments and policies, Brazil could emerge as a global leader in this new energy era.
The discourse on the use of renewable energy as an alternative to fossil fuels has gained strength in recent times, mainly due to the climate crisis. In addition, non-renewable energy sources, such as oil and its derivatives, are finite resources that took millions of years to become available.
Energy efficiency became a topic of discussion shortly after the oil crisis in the 1970s, when it was realized that fossil reserves would not be cheap and abundant forever. In addition, it was also at this time that there was a greater awareness of the damage that the use of this type of fuel generated for the environment. As a result, it was necessary to think of alternatives to maintain energy generation, using other sources and improving the efficiency of those already used.
How important is natural gas in the energy transition? The change in the energy matrix of countries is already a reality. However, each nation opts for sources that are more interesting for the domestic scenario of their countries. In this sense, Brazil has specific challenges in the application of natural gas in this process, ranging from marketing issues to infrastructure and logistics regulation.
The energy transition is a subject that has become a trend in many countries. With the advance of global warming and its consequences, there is an urgent need for migration to a low carbon economy.
How will energy consumption in Brazil in the next decade? The energy sector in the country and around the world has been undergoing a transition with the aim of promoting decarbonization, digitization and decentralization (3Ds).
Unfortunately, Brazil has not had a good position in reducing the emission of greenhouse gases. While other countries had a reduction of almost 7% with the effects of the pandemic, our country increased this rate by 9.5%. Of the five sectors of the economy that account for the totality of emissions in the country: three increased (agriculture, waste and land use change), one remained stable (industrial processes) and one declined (energy).
In the current scenario in the country, understanding what energy efficiency is is important to identify opportunities for optimization from generation to consumption. In times of water and energy crisis, these actions help to reduce costs, maintain supply and reduce waste, which also contributes to the environment. Thus, energy efficiency aims to optimize the use of energy sources to reduce costs and collaborate with the environment. That is, carry out the same processes using fewer resources.
