EXCLUSIVE: Half a Million Balsa Trees Illegally Logged in Amazon Rainforest Every Year to Feed Global Wind Turbine Demand

Another inconvenient environmental catastrophe swept under the carpet

Over half a million balsa hardwood trees are being illegally logged in the Amazon rainforest every year to feed the massive demand for wind turbines in many parts of the world. Balsa is a lightweight but strong wood that is commonly used in the core of giant turbine blades. It can make up around 7% of the blade and each set of three can use up to 40 trees.

This discovery is a genuine shock and follows an exclusive investigation by the Daily Sceptic. It adds to the huge ecological toll that the ‘green’ wind turbines are taking on the natural environment. These inefficient, unreliable, unsightly monsters require a large footprint on land and sea, kill millions of bats, decimate raptor populations, sweep the air of quadrillions of insects and alter local ecology on both land and sea. Nobody would install one in a free market, so they require vast financial subsidies to produce expensive electricity.

Given what is known about annual balsa production, the scale of illegal logging and the demands of wind turbine manufactures, it is not difficult to arrive at a possible Amazon forest yearly loss of over half a million trees. Most commercial balsa is exported by Ecuador and it has produced approximately 500,000 cubic metres annually in recent years, or about 80,000 metric tonnes. Around 55% of production is thought to end up in wind turbines and each group of three requires about 10.5m³ a set. Each set requires about 40 trees so annual balsa consumption for wind turbines equates to 1,047,619. Balsa is a relatively fast growing tropical wood and until the soaring demand from turbines kicked in, it was harvested in sustainable plantations. But since the turn of the decade, this sustainable harvest cannot keep up with demand. In a damning survey, the Environment Investigation Agency (EIA) found that exports were boosted by up to 50% following illegal logging in virgin rainforest.

Halve the turbine consumption of 1,047,619 trees and the illegal logging amounts to around 523,810 mature specimens. This figure is likely to be controversial so the Daily Sceptic has shown its workings-out in full. But any substantial annual cull is horrific, and far outstrips the one-off loss of 100,000 tropical rainforest trees logged to build a convenient road for delegates attending the recent ‘save the forest’ COP30 meeting in the Brazilian city of Belém.
