The hazards community can provide expertise in impacts assessment, in communication of warnings, and in linking the needs of users to research. Some basic lessons learned from the weather and climate arena relates to the importance of measuring impacts and public benefits, of developing useful forecast products, and of getting feedback from users of interdisciplinary work. There is a lack of research to many of the questions regarding space weather hazards. More attention is now paid in the planning process to see what communication will work. One should plan for a variety of systems, in order to build in redundancy.
Economic impacts can be significant.
For example, Hydro Quebec ran 800 hours in a non-optimal way the year after a storm caused an outage, in response to storm forecasts. They are down to 200 hours now, as a result of better forecasts. Non-economic steps are taken as a safety factor in order to avoid brownouts. With better forecasts, systems can become more efficient. Warnings are free.
