“…A similar methodology is employed in two recent studies that take place in Japan, where DST is continually debated but not currently practiced. Fong et al (2007) use a simulation model to investigate the effects of DST on household lighting, and they find a reduction in electricity consumption that differs by region. 7 Shimoda et al (2007) conduct a similar exercise, with the added consideration of DST's effect on residential cooling.…”

The history of Daylight Saving Time (DST) has been long and controversial. Throughout its implementation during World Wars I and II, the oil embargo of the 1970s, consistent practice today, and recent extensions, the primary rationale for DST has always been to promote energy conservation. Nevertheless, there is surprisingly little evidence that DST actually saves energy. This paper takes advantage of a natural experiment in the state of Indiana to provide the first empirical estimates of DST effects on electricity consumption in the United States since the mid-1970s. Focusing on residential electricity demand, we conduct the first-ever study that uses micro-data on households to estimate an overall DST effect. The dataset consists of more than 7 million observations on monthly billing data for the vast majority of households in southern Indiana for three years. Our main finding is that-contrary to the policy's intent-DST increases residential electricity demand. Estimates of the overall increase are approximately 1 percent, but we find that the effect is not constant throughout the DST period. DST causes the greatest increase in electricity consumption in the fall, when estimates range between 2 and 4 percent. These findings are consistent with simulation results that point to a tradeoff between reducing demand for lighting and increasing demand for heating and cooling. We estimate a cost of increased electricity bills to Indiana households of $9 million per year. We also estimate social costs of increased pollution emissions that range from $1.7 to $5.5 million per year. Finally, we argue that the effect is likely to be even stronger in other regions of the United States.

“…Desde una perspectiva diferente, Rock (1997) se acoge a un modelo de simulación para predecir el uso de energía en una residencia representativa de los Estados Unidos y descubre que el consumo de electricidad aumenta ligeramente cuando se emplea el DST. De modo similar, Fong et al (2007) simulan una variedad de escenarios de tiempo de ahorro de luz diurna para distintas regiones en Japón y concluyen que un DST por doble partida (es decir, + 2 horas.) constituiría el marco óptimo para el consumo energético en los hogares.…”

Background: Daylight saving time (DST) has been actively used as a mechanism for energy conservation and reduction of greenhouse gas emissions. In the case of Argentina, the most recent experiences with DST occurred during the austral summer periods of 2007-2008 and 2008-2009, when the policy was finally abandoned. However, the benefits of DST and the size of the (potential) energy savings are still part of an ongoing discussion in a country where energy subsidies imply a heavy fiscal burden. Methodology: Using a difference-in-differences framework that exploits the quasi-experimental nature of the program implementation, we use hourly data for the 2005-2010 period at the province level and estimate the impact of DST on electricity consumption and on peak demand. Results: The application of DST increased total electricity consumption between 0.4% and 0.6%, but decreased aggregate national peak demand between 2.4% and 2.9%. In monetary terms, DST represented extra generation costs of 10.9 and 18 million USD during summers

Brock used a simulation analysis to determine the impact of DST on the energy use of a typical single family home throughout the US (Brock, 1997).…”

“…The data analysis indicated that the extension of DST actually increased both electricity energy use and peak demand. Fong et al (2007) used a simulation analysis to assess the impact of DST on the residential sector in Japan. They found that DST reduces household lighting energy use but the magnitude of the reduction depends on the location.…”

Energy Savings Potential of the Summer Time Concept in Different Regions of JapanFrom the Perspective of Household Lighting

Abstract: Summer Time is a convention in which clocks are uniformly set one hour or more ahead of standard time to provide more daylight in the evenings during late spring, summer, and early fall.
