The world's hunger for energy, especially for electricity, is growing. This trend is being driven by increasing electrification in transport, heating, and industry. According to a study by the World Energy Council (WEC), global electricity demand will increase by almost 150 percent by 2060 compared with 2015. This growth cannot be met with renewable energies alone. Nuclear fusion technologies have currently made important progress. This requires powerful lasers, for which Heraeus Conamic supplies high purity fused silica.
