The benefits of DST are decreased electricity consumption, a slight drop in the number of traffic accidents and crime. One of the benefits of DST is decreased electricity demand which is highly affected by the geographical location. A study at 224 locations around the United States showed that DST increases yearly residential energy costs by 0.147% on average when DST with standard time is used compared to year-round standard time. Ramos and Diaz (1999) showed that the implementation of DST in Mexico in 1996 brought overall electricity usage savings of 0.83%.
A research (Reincke and Van den Broek, 1999 cited in Aries and Newsham, 2008) conducted in 15 countries in European Union revealed that DST would reduce the electricity demand for lighting in the evening for households by 1% or less, and increase demand for heating by 9%. DST means fewer car accidents because more people are driving when the sun is out, which is safer than in the dark (Avis, 2005). On the other hand The Home Office in the UK commented in the mid nineties that "although many crimes are committed when it is dark, definite conclusions are difficult to draw as regards the effect of darkness on overall levels of crime. British Crime Survey (BCS) between 1988 and 1992 show that over half of criminal offences take place during the hours of darkness in the late afternoon or evening, far more occur at dusk rather than dawn. During DST, sun sets one hour later, providing more sunlight for after work outdoor activities. A study conducted in European Union showed that DST increases leisure sector turnover by 3% for the EU as a whole (Aries, Newsham, 2008). Transition into DST may have a disturbing effect on the rest-activity cycle in those healthy adults who are short-sleepers or more of the evening type (Lahti, et al., 2006).
Even though the short-sleepers or more of the evening type individuals may get disturbed by the transition to DST, there was no significant effect in the sample as a whole (Lahti, et al., 2006).
The participants were divided into groups by the preferred daily activity patterns as morning, intermediate or evening type and the preferred length of sleep. DST affects everybody in a society, but most probably there are no long term effects on the circadian rhythms or rest-activity cycles in healthy individuals. On the basis of a traffic analysis, it has been shown that the DST applied in summer months, causes a rise in evening traffic and creates an increase in fuel consumption and thus a higher pollution level in the atmosphere (Hecq, Borisov, Totte, 1993).

A research (Lahti, Haukka, LA¶nnqvist, Partonen, 2008) showed that the DST change in spring and autumn does not increase hospital treatments for accidents nor does it increase manic episodes. Business expectations and preferences regarding the introduction of daylight saving in Queensland. This section will include articles from newspapers, magazines, and other news media from our loved cast members from the Time Tunnel TV series.
Well before the assassination attempt this past October, Malala Yousafzai had emerged as a leading women’s rights activist in Pakistan. With a focus on compassion, the leader of the Catholic Church has become a new voice of conscience. The basis for DST is to improve the match between the daylight hours and the activity peaks of a population. If the clocks were moved forward by one hour during standard time and during daylight saving time, a slight reduction in total residential energy consumption was noticed. In their conclusion, they estimated an overall positive but small effect of DST, with overall electricity savings ranging from 0% to 0.5%, depending on the country. People return home from work and school and complete more errands and activities in the daylight, their exposure to some crimes lessens, since these are more common in the dark than in the daylight (Worthington, 2005 and Committee on Space Science and Technology, 2001). Increasing daylight may for example have different effects for different crimes" (The Royal Society for the Prevention of Accidents (RoSPA), 2005). Long-sleepers needing more than 8 hours of sleep per night and short-sleepers needing 8 hours or less sleep per night (Lahti, et al., 2006). In the case of patients the effects of the transition into DST may be stronger (Lahti, et al., 2006). The data used was patient records from the Finnish hospitals consisting a time period from 1987 to 2003 one week before and after the daylight saving time changes. Summer time, thorough examination of the implications of summer-time arrangements in the Member States of the European Union. Thus the reason for DST is still a reduction in electricity usage but there are also recreational benefits, boosting of the economy by increased consumption and a reduction of pedestrian accidents and crime.

In a case where daylight saving time was observed year-round, no significant effects were noticed on energy usage or in electricity costs (Rock, 1997). Often the use of extra air-conditioning in warmer evenings is not accounted for, and could increase the overall electricity consumption. The effects of daylight and daylight saving time on US pedestrian fatalities and motor vehicle occupant fatalities. Executive summary, Research voor Beleid International (RvB) for the European Commission DG VII. Daylight saving time transitions and hospital treatments due to accidents or manic episodes.
Transition into daylight saving time influences the fragmentation of the rest-activity cycle.
According to a academic study in 1999, the spring and fall time changes costs 60 billion US dollars to investors.
The study also noted that during afternoon hours, the light conditions were the cause of the fatal crashes rather than the clock times. The 1986 DST extension in the US benefited Barbecue Industry Association, the American Association of Nurserymen and convenience-store owners by 135 billion US dollars (Brearton, 2011). The fatal accident increase for pedestrians were much larger than for vehicle occupants when the light conditions changed from light to twilight.
