Thermoelectric plants play a crucial role in Brazil's energy matrix, especially in times of water crisis, when hydroelectric plants are compromised. Despite being a reliable source, these plants, which use fuels such as natural gas, coal and biomass, have a significant environmental impact, mainly due to greenhouse gas emissions. With the increase in demand for energy, thermoelectric plants are gaining ground in the energy scenario, but Brazil seeks to balance their use with the expansion of renewable sources, aiming for a more sustainable future.
