When DST was introduced after the first oil crisis in the 1970s, it looked like it would sweep the world: Almost every country outside the tropics was observing it. But most nations have abolished it, most recently Argentina and Russia. DST not only causes confusion (for example, during the autumn transition, the German railway stops all trains for an hour to skip over the "double-hour") but also increases heart attacks, accidents and suicides especially during the spring transition, when people are forced to rise one hour earlier. Also, as so often the case for government programs, the projected savings never materialized. Many studies show that electricity savings for reduced lightning in the evening are outweighted by higher demand for cooling in the afternoon and increased lightning in the morning. |
