How has the Itaipu dam impacted the environment?
To ensure water quantity and quality, Itaipu has created an environmental conservation area, planting more than 44 million trees. The protected areas now total over 100,000 hectares, including reserves and wildlife refuges in both countries and the biological forest corridor that protects the reservoir.
How many people died building the Itaipu dam?
As negative effects, we can mention the displacement of 10.000 families and the death of 149 workers during the construction, besides many other accidents and diseases. From a very controversial project, Itaipu became a very important source of energy to support Brazilian economic growth.
Why is hydroelectric dam bad?
Building dams destroys the natural defense system that healthy rivers give our communities. Hydropower dams can contribute to global warming pollution: When a forest is cut down to make way for a dam and reservoir, those trees are no longer available to absorb the carbon dioxide added by fossil fuels.
What are the benefits and the drawbacks of building Itaipu dam?

What is the purpose of Itaipu dam?
The purpose of the dam was the production of electricity to supply Brazil and Paraguay with the power needed to contribute to modern industrial development.
Is the Itaipu dam sustainable?
Itaipu has played a major role supporting sustainable development in Paraguay and Brazil by providing access to reliable, sustainable and clean electricity that has powered prosperity for the people of both countries (Sória, 2012).
Why was Itaipu built?

How do dams damage the environment?
Dams store water, provide renewable energy and prevent floods. Unfortunately, they also worsen the impact of climate change. They release greenhouse gases, destroy carbon sinks in wetlands and oceans, deprive ecosystems of nutrients, destroy habitats, increase sea levels, waste water and displace poor communities.
What does the Itaipu dam do?
Itaipu Hydroelectric Dam is the world’s second-largest operational hydroelectric power plant in terms of installed power. With an installed generation capacity of 14GW, the plant is operated by Itaipu Binacional and located on the border between Brazil and Paraguay.
How much energy does the Itaipu dam generate?
With more than 20 generating unities and 14.000 MW of installed power, Itaipu provides 10.8% of the energy consumed in Brazil and 88.5% of the energy consumed in Paraguay. It is the largest clean, renewable energy generator of the planet, having produced more than 2.7 million GWh since it started operating.
