In 2000 and 2001, the use of child slaves on cocoa farms in West Africa was exposed in a series of documentaries and pieces of investigative journalism, sparking an international outcry .

The cryptocurrency bitcoin now uses up more electricity a year than the whole of Argentina, according to recent estimates from the University of Cambridge. That’s because the creation of a bitcoin, in a process called mining, is achieved by powerful computers that work night and day to decode and solve complex mathematical problems. The energy […]

Tides are more predictable than winds or sunshine. Then, why are not they already widely used as a source of renewable energy? The simple answer is that designing and building an ocean energy array is quite complex. This complexity has an associated variability in the cost of energy that makes projects difficult to evaluate from […]

Behavioral Economics studies the systematic biases in economic decisions that occur because our cognitive processes are constrained and, thus, context-neutral optimization is impracticable. This area of research started with Tversky and Kahneman (1974) , and […]
