Brazil’s paradoxical energy policy

Adenilson Munduruku's bodySão Paulo, 22 January – Jerky mobile phone footage shows men carrying the inert body of a young man, surrounded by distraught, weeping women. Their wailing is clearly audible, as are the shrieks of a pet monkey which scurries in and out of the crowd.

The body is finally laid at the feet of the young man`s mother. She strokes away the hair over a bullet wound in his forehead, while others point to bullet holes in his legs.

Adenilson Kirixi Munduruku was shot during a federal police operation, purportedly to clear illegal goldminers from the Teles Pires river in the Brazilian Amazon.  Dressed for jungle warfare, the police threw teargas and fired rifles while a police helicopter flew low over the crowd.

But the Munduruku Indians believe the real aim of the operation last November was to intimidate the villagers who have been protesting against a dam being built on the river, which will flood their sacred places.

The Teles Pires dam is one of five planned for the Tapajos river system, a major tributary of the Amazon and the last undammed river running from Brazil’s central plateau to the Amazon basin.

Water levels drop

At least 30 large dams are planned for the Amazon region. If they all go ahead, every one of the major rivers which feed into the mighty Amazon will be dammed. The Brazilian government claims to have one of the cleanest energy systems in the world, with over 70% of  the country`s energy provided by hydroelectric power.

That claim is now being challenged as changes to Brazil’s weather pattern produce lower rainfall and more frequent  droughts, causing the levels of reservoirs and rivers to fall.

Earlier dams like Tucurui on the Tocantins river inundated vast areas of forest to form giant lakes, but the newer generation of dams like Belo Monte on the Xingu, and Jirau and Santo Antonio on the Madeira, use the “run-of-the river” (fio d`agua)  system, with much smaller reservoirs dependent on abundant rains.

The Brazilian press is now full of alarmist stories about the possibility of electricity rationing, because of the fall in the level of the reservoirs.  The government firmly denies this will happen.

But while environmentalists see this as an opportunity to invest more in other renewables, like wind and solar power, the government has preferred to fall back on the increasing use of coal, diesel or gas-fired  plants to make up the shortfall.

Between October and December 2012 these plants produced 15.3 million tonnes of CO2 emissions, according to a study by WayCarbon, an environmental consultancy company, published in O Globo newspaper on 12 January.

This position has drawn criticism from within the government itself. Tasso Azevedo, a Ministry of the Environment adviser, said that last year the annual total for emissions from these plants was higher than those caused by deforestation.

He said that it made no sense to dirty Brazil`s energy mix with the use of thermal power, “when the country has the greatest potential for wind, solar, hydro and biomass power in the world”.

Yet instead of investing in wind or solar power, the government has doubled the number of thermal plants in the last 10 years, to over 1,100.

Shrinking parks

The idea that hydroelectric dams are emission-free is also being challenged. After reviewing a number of studies Philip Fearnside, professor of ecology at INPA, the National Institute of Amazonian Research in Manaus, found that “in all of these studies, their overall conclusion that tropical dams emit substantial amounts of greenhouse gases in their first 10 years is clear and robust”.

Fearnside, an American who has lived in Brazil for 30 years, is a widely cited global warming scientist. Referring to the Teles Pires dam which the Munduruku Indians are fighting, he said the government’s claim that it will “generate greenhouse gas emission-free electricity cannot be substantiated”.

To build the five dams on the Tapajos, which will together inundate an area of almost 2,000 sq.kms, the government has reduced the size of several national parks and conservation areas around the river.

Many riverine communities, not the Munduruku alone, will be dislodged from what till now has been a relatively unspoilt area of biodiversity.

Edison Lobão, the energy minister, is unapologetic: “Over the next ten years we have to meet the challenge of doubling our installed electrical energy capacity of 121,000 MW”.
