“…Of these, the sum of residential and commercial electricity consumption was used to estimate base temperature through the analysis of the relationship with temperatures. Industrial electric energy consumption is not used, since previous investigations as well as this study's findings indicate that it is not temperature sensitive (Elkhafif 1996;Sailor and Munoz 1997;Amato et al 2005). Additionally, previous studies have shown that air temperature is the most significant weather variable affecting electricity consumption, while other variables (wind speed, humidity, etc.)…”

In South Korea, heating degree-days (HDD) and cooling degree-days (CDD) have been widely used as climatic indicators for the assessment of the impact of climate change, but arbitrary or customary base temperatures have been used for calculation of HDD and CDD. The purpose of this study is to determine real base temperatures to accurately calculate HDD and CDD for South Korea, using monthly electric energy consumption and mean temperature data from 2001 to 2010. The results reveal that the regional electricity demand generally depends on air temperature in a V-shaped curve in urban settings but in an L-shaped curve in rural settings, indicating that the sensitivity of the electricity demand to the temperature change is affected by the size of cities. The South Korean regional base temperatures, defined by a piecewise linear regression method, range from 14.78 to 19.48C. These results suggest that the assessment of climate change impacts on the energy sector in South Korea should be carried out on a regional scale.

Regional Energy Demand Responses To Climate Change: Methodology And Application To The Commonwealth Of Massachusetts

Climate is a major determinant of energy demand. Changes in climate may alter energy demand as well as energy demand patterns. This study investigates the implications of climate change for energy demand under the hypothesis that impacts are scale dependent due to region-specific climatic variables, infrastructure, socioeconomic, and energy use profiles.In this analysis we explore regional energy demand responses to climate change by assessing temperature-sensitive energy demand in the Commonwealth of Massachusetts. The study employs a two-step estimation and modeling procedure. The first step evaluates the historic temperature sensitivity of residential and commercial demand for electricity and heating fuels, using a degree-day methodology. We find that when controlling for socioeconomic factors, degree-day variables have significant explanatory power in describing historic changes in residential and commercial energy demands. In the second step, we assess potential future energy demand responses to scenarios of climate change. Model results are based on alternative climate scenarios that were specifically derived for the region on the basis of local climatological data, coupled with regional information from available global climate models. We find notable changes with respect to overall energy consumption by, and energy mix of the residential and commercial sectors in the region. On the basis of our findings, we identify several methodological issues relevant to the development of climate change impact assessments of energy demand.

“…Because most commercial establishments and office buildings already have air conditioning units, it is assumed that only short‐term effects are relevant to the commercial sector, but for the residential sector both short‐term and long‐term effects are relevant. Industrial electricity consumption is much less sensitive to temperature than are residential and commercial uses [ Amato et al ., ; Elkhafif , ; Sailor and Muñoz , ] and is ignored here. Thus, two factors were estimated, one for commercial use that includes only a short‐term effect ( M comm ) and the other for residential use that includes a combined short‐term and long‐term effect ( M resid ).…”

[1] Relying on the U.S. Geological Survey water use data for the period 1960À2005, this paper summarizes past water use and then projects future water use based on the trends in water use efficiency and major drivers of water use. Water use efficiency has improved in most sectors. Over the past 45 years, withdrawals in industry and at thermoelectric plants have steadily dropped per unit of output. In addition, domestic and public withdrawals per capita, and irrigation withdrawals per unit area in most regions of the west, have recently begun to decrease. If these efficiency trends continue and trends in water use drivers proceed as expected, in the absence of additional climate change the desired withdrawals in the United States over the next 50 years are projected to stay within 3% of the 2005 level despite an expected 51% increase in population. However, including the effects of future climate change substantially increases this projection. The climate-based increase in the projected water use is attributable mainly to increases in agricultural and landscape irrigation in response to rising potential evapotranspiration, and to a much lesser extent to water use in electricity production in response to increased space cooling needs as temperatures rise. The increases in projected withdrawal vary greatly across the 98 basins examined, with some showing decreases and others showing very large increases, and are sensitive to the emission scenario and global climate model employed. The increases were also found to be larger if potential evapotranspiration is estimated using a temperaturebased method as opposed to a physically based method accounting for energy, humidity, and wind speed.
