«I'd like you to notice that I'm not wearing a tie», highlighted Pedro Sánchez during a press conference in July 2022. «We can all save energy with a small gesture [...]. This way, we will all contribute to the energy saving so needed by our country», observed the Spanish Prime Minister. Spain is, in fact, more affected than others by the effects of global warming which, during last summer, led to abnormal heat waves in multiple cities. The interesting thing is that local authorities are seeking to experiment with non-conventional technologies to tackle climate change in addition to the more traditional and far-reaching policies. We have seen it in Seville and Gran Canaria which rediscovered techniques that were used in the past to help tackle the climate crisis.
The local authorities in Seville, in the south of Spain, had been looking for solutions to counter the consequences of a further increase in temperatures due to global warming. In the summer, the Andalusian capital often reaches temperatures exceeding 40°C, which makes it one of the hottest cities in Europe. The technology they opted for, which is also found in other countries characterised by a particularly dry climate, derives directly from the so-called "qanat", i.e. special wells that were developed in ancient Persia over 1,000 years ago.
