      Bin Afif, Mohammed; Bin Afif, Abdulla Shaikh Abdul Qader; Apostorleris, Harry; Gandhi, K; Dadlani, Anup; Ghaferi, AA; Torgersen, Jan; Chiesa, Matteo (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-17)
      Rapidly declining costs of renewable energy technologies have made solar and wind the cheapest sources of energy in many parts of the world. This has been seen primarily as enabling the rapid decarbonization of the electricity sector, but low-cost, low-carbon energy can have a great secondary impact by reducing the costs of energy-intensive decarbonization efforts in other areas. In this study, ...

    • Colours and maps for communicating natural hazards to users with and without colour vision deficiency 

      Engeset, Rune Verpe; Pfuhl, Gerit; Orten, Camilla; Hendrikx, Jordy; Hetland, Audun (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-14)
      Natural hazards are often communicated visually using colours and maps. However, users' ability to read and understand these products may be hampered by e.g., colour vision deficiency, potentially rendering the products less effective or even counter effective. To study these effects, we conducted two web-based surveys and analysed how to improve visual communication of avalanches, floods, landslides, ...
