The influence of energy efficiency on other natural resources use: An input-output perspective

Energy efficiency improvements reduce the costs of energy services, and under some circumstances, increase the available income. This generates an additional increase of consumption of goods and services that need additional energy to be produced, distributed and consumed. This effect is known as the indirect rebound effect in the literature. However, beyond this additional increase of global energy consumption, there is also a variation of the use of other natural resources due to the same mechanism. This effect, which we label as direct and indirect cross rebound effect, is generally not considered by academia nor policy-making when designing and implementing energy policies. This research conceptualizes this effect, develops a methodology for its estimation and provides estimates for the Spanish economy. Results show that an energy efficiency in households could increase the use of minerals and water, while reducing the use of energy, fossil fuels and metal ores in Spain. These reductions, however, are lower than the expected ones from an input-output perspective, leading to positive direct and indirect cross rebound effects: between 64.6% and 74.7% for energy (equivalent to direct and indirect rebound effect); 48%–63% for fossil fuels. 84%–89% for metal ores; backfire for non-metallic minerals (147%–134%) and extreme backfire for water (1191%–1628%)

Comparison of Large-Scale Vented Deflagration Tests to CFD Simulations for Partially Congested Enclosures

PresentationThis paper presents a comparison between the results from a test program carried out to characterize the blast load environment within BakerRisk’s Deflagration Load Generator (DLG) test rig, and predictions made using the FLACS computational fluid dynamics (CFD) code. The test data was also compared to internal peak pressure predictions made using the National Fire Protection Association’s Standard on Explosion Protection by Deflagration Venting (NFPA 68) [1]. The purpose of these tests was to provide data for comparison with standard methods used to predict internal blast loads in a vented deflagration. The tests also provided a characterization of the internal DLG blast load environment for equipment qualification testing. The DLG test rig is 48 feet wide × 24 feet deep × 12 feet tall and is enclosed by three solid walls, a roof, and floor, with venting through one of the long walls (i.e., 48-foot by 12-foot). During testing, the venting face of the rig was sealed with a 6 mil (0.15 mm) thick plastic vapor barrier to allow for the formation of a near-stoichiometric propane-air mixture throughout the rig. The flammable gas cloud was ignited near the center of the rear wall. Congestion inside the rig was provided by a regular array of vertical cylinders (2-inch outer diameter) that occupied the rear half of the rig; the front half of the rig was uncongested (i.e., as would be the case for equipment qualification testing). Forty-three pressure transducers were deployed internal and external to the rig to measure blast pressure histories. Three series of tests were conducted with congestion levels varying from an area blockage ratio (ABR) of 11% in Test Series A to ABR values of 7.6% and 4.2%, respectively, in Test Series B and C. The obstacle-to-enclosure surface area ratio (Ar), a perameter used within the NFPA 68 correlations to quantify congestion, was equal to 0.45, 0.32, and 0.17 for test series A, B and C, respectively. The peak pressures and impulses for each test are provided, along with pressure histories internal and external to the rig for selected tests. Comparisons of the test data t

Economic structure and energy savings from energy efficiency in households

When an energy efficiency improvement occurs at the household level, several mechanisms, grouped under the name of the rebound effect, increase the available income and consumption, increasing the total energy consumption of the economic structure. The present research analyses the links between energy efficiency improvements in households, consumption, and the economic structure in an input-output framework. We examine, from an empirical perspective, the relationship between energy efficiency improvements and the economic structure, and between the direct and the indirect rebound effect. The limits of the input-output methodology in assessing the direct and indirect rebound effect have been empirically tested with respect to efficiency improvements of electricity uses in households in Catalonia

Regional surface temperature simulations over the Iberian Peninsula: evaluation and climate projections

The realism of a specifc confguration of the WRF Regional Climate Model (RCM) to represent the observed temperature evolution over the Iberian Peninsula (IP) in the 1971–2005 period has been analyzed. The E-OBS observational dataset was used for this purpose. Also, the added value of the WRF simulations with respect to the IPSL Earth System Model (ESM) used to drive the WRF RCM was evaluated. In general, WRF presents lower temperatures than in the observations (negative biases) over the IP. These biases are comparatively larger than those of the driving ESM. Once the biases are corrected, WRF provides an added value in terms of a higher spatial representation. WRF introduces more variability in some regions in comparison to gridded observation. Warming trends according to the observations are also well represented by the RCM. In the second part of this study, the projections of future climate performed with both the ESM and the RCM were evaluated for the RCP4.5 and RCP8.5 scenarios during the 21st century. Although both models simulate temperature increases, the RCM simulates a smaller warming than the ESM after the mid-21st century, except for winter. Using the WRF model, the maximum temperature increase reaches 6 ◦C and 3 ◦C for RCP8.5 and RCP4.5 in the south east of the Iberian Peninsula by the end of the 21st century, respectively

Economy-wide rebound makes UK's electric car subsidy fall short of expectations

Environmental policies often underperform due to so-called rebound effects, namely behavioural and systemic responses to technical change leading to additional consumption and environmental damage. While evidence of rebound is abundant, studies generally focus on technical changes that are neither associated with specific technologies nor their production costs, making it difficult to connect these changes with the policies governing them. To overcome this limitation, this study proposes to combine a technology-rich model based on life cycle assessment and a behaviour-optimising model for the global economy based on computable general equilibrium modelling. This approach allows to quantify policy-induced economy-wide rebound effects for four relevant environmental impacts: climate change, acidification, photochemical ozone formation, and particulate matter. We apply this approach to evaluate the effectiveness of the United Kingdom's subsidy on electric cars. The results show notable economy-wide rebound effects associated with this subsidy: over or close to 100% (no environmental benefits) for acidification and particulate matter impacts, and a lower, yet notable, magnitude for climate change (~20–50%) and photochemical ozone formation (~30–80%) impacts. The results also show the important role of macro-economic effects from price changes, particularly how the shift from petrol to electricity triggered additional demand for cheaper petrol

Improvement of Inter-Professional Collaborative Work Abilities in Mexican Medical and Nursing Students: A Longitudinal Study

Background: Inter-professional and interpersonal relationships in collaborative work environments can prove to be critical elements in healthcare practice. When implementers fail to understand the importance of a collaborative perspective, this can lead to communication problems which ultimately harm the users. Objectives: To improve the inter-professional collaborative work skills of Mexican students in their first year of medical and nursing degrees through the use of a training program geared toward development of interpersonal skills and interdisciplinary work. Results: The control group of medical students showed a deterioration in the development of collaborative work skills (p < 0.01), whereas in the experimental group this deterioration was not present. In the experimental group of nursing students, a significant increase in the development of collaborative work skills (p < 0.05) was observed. The differences were clearly due to the professional area of study (p < 0.001). Conclusion: There are differences in collaborative work skill development among different professional areas. These differences can be reduced through the implementation of a program aimed at developing collaborative work and interpersonal skills in the early stages of training.This study was supported by the Rioja Salud Foundation (FRS), Spain, and by a grant from the Instituto de Salud Carlos III (Pi16/01934), co-financed by Operational Program of the European Regional Development Fund (FEDER-La Rioja) in Spain (6FRS-ABC-012)
