Energy Sources and Environmental Impact

The video tutorial explores various energy sources, categorizing them into renewable and non-renewable types. Renewable energy sources include hydroelectric, solar, wind, geothermal, biomass, and tidal energy, which are sustainable and environmentally friendly. Non-renewable sources, such as fossil fuels and nuclear energy, are limited and often harmful to the environment. The video highlights the significance of these energy types, their applications, and their impact on the environment, particularly focusing on Brazil's energy landscape.
