When it comes to energy, water scarcity seems to dominate the agenda, but there is light at the end of the tunnel in this entire crisis, and it is renewable. Currently, half of the energy produced in Brazil comes from renewable sources, according to data from the Ministry of Mines and Energy, and the generation of wind, wind, and solar energy has been gaining prominence in this scenario. The country has plenty of capacity to become a powerhouse in renewable energy.
The production of solar energy represents 2% of Brazil's energy matrix, but the growth of this source has been by leaps and bounds. In the last three years, the growth of centralized solar energy (generated by large plants) was 200%, while distributed solar energy (small generation plants) exceeded 2,000%.
According to the Ministry of Mines and Energy, in 2020, in the midst of the pandemic, the installed capacity in photovoltaic solar energy grew by 66% in the country. The result is a reflection of incentives, such as the elimination of import taxes for solar energy equipment.
Data from the National Institute for Space Research – INPE show that Brazil can generate 5 trillion megawatts per year from the solar array alone, whose growth was almost 70% in 2021 alone. This represents no less than four times more than a mermaid hydroelectric plant capable of producing in the same period, not to mention the savings of up to 95% that the solar source can guarantee to consumers.
According to information from the National Electric System Operator (ONS), wind energy currently represents 10.9% of the Brazilian electricity matrix, and perspectives point to this percentage exceeding 13% by the end of 2025. The Northeast Region is highlighted in this production. In a single day, the unprecedented average production reached 11,399 MW, enough to supply the entire Northeast Region for 24 hours.
Earlier this month, the interior of Paraíba received another billion dollar investment in the sector. The project will allow the generation of 242MW, which is equivalent to the consumption of 700 thousand families during a year and would avoid the emission, for the same period, of around 208,000 tons of carbon dioxide into the atmosphere.
Waste that turns into energy
Despite the good news in the clean energy sector, Brazil still has incentives far below the country's generation potential, and the need for more investment was urgent given the rain crisis that resulted in a 10% decrease in production hydroelectric energy and required an increase of the same order in the production of thermoelectric energy, which is more expensive and polluting.
In this context, companies and industry need to bet on measures that reduce energy costs, avoiding waste and unsustainable operations. A key part of Prosumir, the Pressure Reducing Turbine (TRP) proved to be an ally in this task because it generates renewable energy from waste in the form of heat, reducing C02 emissions.
TRP combines performance and sustainability, ensuring energy cost savings of up to 10%. This characteristic is in line with the purpose of responsibility with the country's moment of crisis and with the international commitments to reduce the emission of greenhouse gases.
While there is still no scenario that points to a replacement of the energy system matrix or at least reduces dependence on hydroelectric plants, adopting simple measures helps to reduce costs, environmental damage and increases care for clean and efficient production.
