•The impact of oil price uncertainty on economic growth in OECD countries is studied.•Taking a historic perspective, the sample covers a 144-year period starting in 1870.•The negative impact of ...uncertainty is more severe for oil producing countries.•A smaller impact is recorded in the post-World War II subsample period.•Reasons for declining impact of oil price uncertainty are proposed.
This paper uses a number of different panel data estimators, including fixed effects, bias-corrected least squares dummy variables (LSDVC), generalised methods of moments (GMM), feasible generalised least squares (FGLS), and random coefficients (RC) to analyse the impact of real oil price volatility on the growth in real GDP for 17 member countries of the Organisation for Economic Co-operation and Development (OECD), over a 144-year time period from 1870 to 2013. The main finding of the study is that oil price volatility has a negative and statistically significant impact on economic growth of the OECD countries in the sample. In addition, when allowing for slope heterogeneity, oil-producing countries are significantly negatively impacted by oil price uncertainty, most notably Norway and Canada.

Torrefaction is a mild pyrolysis, which has been explored for the pretreatment of biomass to increase the heating value and hydrophobicity. Due to its potential applications for making torrefied ...pellets, which can be used as a high quality feedstock in gasification for high quality syngas production and as a substitute for coal in thermal power plants and metallurgical processes, torrefaction and densification have attracted great interest in recent years from both academia and bioenergy industry. This paper provides a comprehensive review of research progresses in this area, drawing on major contributions from two major research groups of the authors on torrefaction and densification at Canada and Taiwan as well as literatures. It is revealed that torrefaction of various biomass species and their major components, lignin, cellulose and hemicelluloses have been extensively studied in thermogravimetric apparatus (TGA) under both inert (N2) and oxidative (O2, H2O) environments to elucidate the weight loss as a function of temperature, particle size and time. It was found that the higher heating value and saturated water uptake of torrefied biomass were a strong function of weight loss, which represents the degree of torrefaction. When torrefied sawdust is compressed into torrefied pellets, more mechanical energy is consumed and higher die temperature is required to make torrefied pellets of similar density and hardness as regular pellets. Simple economics analyses based on laboratory scale experimental data showed that because of the potential savings from pellets transport, handling and storage logistics, the overall cost for torrefied pellets can be lower than regular pellets in European market for both European and Canadian pellets. The gasification could be improved in terms of both energy efficiency and syngas quality because of the removal of oxygenated volatile compounds from torrefied biomass.
To investigate the nexus among clean energy consumption, economic growth and CO2 emissions, a newly developed bootstrap ARDL bounds test with structural breaks is employed to survey the cointegration ...and causality for G7 countries. We find no cointegration among real GDP per capita, clean energy consumption and CO2 emissions in Canada, France, Italy, the US and the UK. However, cointegration exists in Germany when real GDP per capita and CO2 emissions serve as dependent variables and in Japan when CO2 emissions is the dependent variable. Regarding the results of causality test that we find clean energy consumption causes real GDP per capita for Canada, Germany and the US and CO2 emissions causes clean energy consumption for Germany. Besides, we find feedbacks between clean energy consumption and CO2 emissions for Germany, and unidirectional causality running from clean energy consumption to CO2 emissions for the US. Our study has important policy implications for G7 countries conducting efficient energy-use strategy to reduce CO2 emissions.
Intergenerational income mobility is lower in the United States than in Canada but varies significantly within each country. Our subnational analysis finds that the national border only partially ...distinguishes the approximately 1,000 regions we analyze within these countries. The Canada-US border divides central and eastern Canada from the US Great Lakes and northeastern regions. Simultaneously, some Canadian regions have more in common with the low-mobility southern parts of the United States than with the rest of Canada; that these areas represent a much larger fraction of the US population also explains why mobility is lower in the United States.
•Developed an oil sands with Steam Assisted Gravity Drainage evaluation model.•Conduct a feasibility study of a typical oil sands development with new model.•Quantify the effects of critical ...parameters on the economics of a development.
Oil sands resource is the third largest oil reserve, and 70% of the oil sands are in Canada. The emerging of Steam Assisted Gravity Drainage technology has made the commercial development of oil sands economically feasible. However, with the recent oil price crash, the development of oil sands has faced an uphill battle. A realistic and integrated evaluation model is highly needed to overcome difficulties from the low oil price and provide meaningful and valuable information for operators as well as investors to make the right decision. The existing evaluation models have considerable limitations (i.e., the incapability of evaluating integrated oil sands development with Steam Assisted Gravity Drainage technology, the lack of investigation into the input parameters with historical data, and ignoring the effect of the subsurface reservoir, etc.). This study developed an integrated evaluation model through the analyses of a significant amount of actual historical data. This integrated model includes six subcomponent models, ranging from the subsurface reservoir to infield flowline. Data from 35 Canadian oil sands development with 15 internal and external parameters were collected and investigated. The oil price effect was analyzed and quantified through simulations. The breakeven Western Canada Select oil price of $39/bbl. (equal to the West Texas Intermediate oil price of $55/bbl.) and other key price points and distributions were identified. Also, the top seven geological and technical parameters that contribute 86% of the net present value variations were identified and investigated. These quantified effects of external and internal parameters are useful findings for decision making. Considering various price scenarios and uncertainties of the input parameters, this study has concluded that developing oil sands resources with the Steam Assisted Gravity Drainage technology is economically feasible and socially beneficial after we take all stakeholder interests into consideration, which is true even with the sustainable and realistic oil price in the foreseeable future.
Understanding the influence of energy technology innovation in reducing a country's greenhouse gas emissions requires a systematic review to characterize the existing system. A comprehensive data ...review of available financing mechanisms and investments by government and industry is undertaken for the case of Canada, coupled with an organized examination of existing international, federal, and regional climate policies that advance innovation. Results indicate that investments from early research and development through to capital expenditures are heavily weighted towards fossil fuels. Though federal efforts to meet international commitments have been unsuccessful, regions implementing high carbon fuel phase-out, renewable portfolio standards, and feed-in-tariffs were found to be successful in reducing emissions. Financing for clean energy projects is readily available; however, there is no complete database available for investors to discover these opportunities. To enhance clean energy innovation in Canada and enable success in emissions reductions, we suggest that investments (from research and development to capital expenditures) and regional policies should be aligned with federal commitments, along with clear communication of available financing to attract clean energy investors. Our approach to a systematic review is broadly applicable to other regions where there is interest in understanding and improving the role of innovation in reducing greenhouse gas emissions, particularly in countries with federalist political systems and large fossil fuel reserves.
Various green rating systems are established globally to evaluate the sustainability of construction projects. Their categories and criteria have been under constant updates to follow the sustainable ...trend of building development. This paper aims to develop a systematic review of the development of green rating systems. The specific objectives are: 1) discover how interest and research in green rating systems have developed; 2) identify the similarity, difference, strength and weakness of green rating systems; 3) examine whether they fully assess the projects in all aspects of sustainability. Specifically, LEED (Leadership in Energy and Environmental Design), BREEAM (Building Research Establishment Assessment Method), CASBEE (Comprehensive Assessment System for Building Environmental Efficiency) and Green Star NZ were analysed in this paper. The results indicate that BREEAM, LEED, and CASBEE have been utilized since late the 2000s while Green Star NZ is still in its earlier stages. 70% of the research papers focusing on BREEAM, LEED, CASBEE are developed geographically in the USA, Canada, the UK, China, and Australia. Although these four rating systems were initiated in different contexts with different standards, Indoor Environment Quality, Energy, and Material are core common categories for all. Environmental concerns are the main focus in New Construction manuals while Society is emphasized in Neighbourhood Development manuals. Currently, BREEAM has been the only tool which could assess all four sustainable factors. Further in-depth research is anticipated to focus more on economic and institutional factors to improve the capability of green rating systems for sustainability assessment purposes.
•Indoor Environment Quality, Energy, and Material are the main focus in green rating systems.•The total categories, points, and mandatory credits of analysed rating schemes tend to increase and more comprehensive.•BREEAM is considered as the strongest rating system at present.•Currently, no rating scheme could assess a project in all aspects of sustainability.
•A sustainable approach of using WCO as a rejuvenator is summarized.•WCO improves cracking resistance but reduces high temperature rutting performance.•Chemical modification of WCO exhibits better ...physical and rheological performances.
In Canada, over 90% of the paved roads are asphalt pavements. Most of these pavements were built decades ago, which are currently exhibiting a significant amount of surface distresses. These distresses includes potholes, rutting (deformation in the wheel path), and cracking. To repair these distressed pavements, the road agencies spend millions of dollars every year, of which a significant portion goes to acquiring new natural aggregates and asphalt. To reduce the rehabilitation cost, road agencies use up to 100% reclaimed asphalt pavements (RAP) in new construction. However, the asphalt available in recycled pavements is oxidized and stiffened due to various environmental processes which are susceptible to thermal and fatigue cracking. To soften and to decrease the viscosity of the RAP materials, various rejuvenators are being in practice. The rejuvenators are able to reactivate and restore the original properties of this long-term aged asphalt binder. Using Waste Cooking Oil (WCO) is one of the eco-friendly solutions which contains the similar lighter oil components of asphalt and can be used as an acceptable rejuvenator. Recent studies showed that WCO has an excellent potential to be used as a good rejuvenator in the hot mix asphalt (HMA) industry. This review article summarizes the performance and adverse effects of WCO as a rejuvenator.
