Alex Txikon, internationally renowned mountaineer, is launching a new winter expedition in 2021 to Manaslu (Nepal). It is the first non-polluting ascent, powered by solar panels. With this sustainable system, which reduces the energy footprint in accordance with the Paris Agreements, the EKI Foundation is beginning its work of solidarity. Alex is going to learn about the work developed by the Foundation in Sierra Leone, where they provide solar energy systems that enable energy autonomy in schools and hospitals. Txikon proposes to replicate this idea in a very special school in the Diamer Valley in Pakistan, the Günter Mountain School, uniting two different but at the same time equal cultures.
