Melting Glaciers: A Growing Threat to Alpine Valleys

3 October 2024 3 October 2024

The sound of melting is all around us as we arrive on the Stubai glacier in Austria. Today the ice may lose a centimetre or two of depth, because the sun is shining and temperatures are well above zero. As we walk slowly from the ski lift, glaciologist Andrea Fischer warns us to watch out for holes and cracks in the icy mud.

Floating Solar Power Plants: A New Horizon for Renewable Energy in Extreme Marine Conditions

27 September 2024 27 September 2024

The development of XolarSurf, a floating solar power plant by Italian startup Saipem, offers a groundbreaking solution to the challenges of clean energy production in extreme marine environments. By harnessing solar energy on the ocean’s surface, XolarSurf presents a promising path forward for regions with limited land space or harsh weather conditions. However, challenges like high initial costs, maintenance in corrosive saltwater, and potential environmental impacts on marine ecosystems remain. With collaboration between governments, the private sector, and international bodies, floating solar technology can play a crucial role in reducing our dependence on fossil fuels and securing a sustainable future for humankind.

Cheapest and Most Expensive Countries for EV Charging in Europe: Understanding the Challenges and Opportunities for Renewable Energy

27 September 2024 27 September 2024

The disparity in EV charging costs across Europe highlights not just economic differences but also the broader challenges of renewable energy integration.
