Abstract

After decades of being largely the preserve of countries in volcanic regions, the use of geothermal energy—for both heat and power applications—is now expanding worldwide. This reflects its excellent low-carbon credentials and its ability to offer baseload and dispatchable output - rare amongst the mainstream renewables. Yet uptake of geothermal still lags behind that of solar and wind, principally because of (i) uncertainties over resource availability in poorly-explored reservoirs and (ii) the concentration of full-lifetime costs into early-stage capital expenditure (capex). Recent advances in reservoir characterization techniques are beginning to narrow the bounds of exploration uncertainty, both by improving estimates of reservoir geometry and properties, and by providing pre-drilling estimates of temperature at depth. Advances in drilling technologies and management have potential to significantly lower initial capex, while operating expenditure is being further reduced by more effective reservoir management — supported by robust mathematical models — and increasingly efficient energy conversion systems (flash, binary and combined-heat-and-power). Advances in characterization and modelling are also improving management of shallow low-enthalpy resources that can only be exploited using heat-pump technology. Taken together with increased public appreciation of the benefits of geothermal, the technology is finally ready to take its place as a mainstream renewable technology, This book draws together some of the latest developments in concepts and technology that are enabling the growing realisation of the global potential of geothermal energy in all its manifestations.After decades of being largely the preserve of countries in volcanic regions, the use of geothermal energy—for both heat and power applications—is now expanding worldwide.

Abstract

Prior to May 2015, the oil-rich jurisdiction of Alberta had, for over four decades, been a one-party state. During that time, the rule of the Progressive Conservatives essentially went unchallenged, with critiques of government policy falling on deaf ears and Alberta ranking behind other provinces in voter turnout. Given the province’s economic reliance on oil revenues, a symbiotic relationship also developed between government and the oil industry. Cross-national studies have detected a correlation between oil-dependent economies and authoritarian rule, a pattern particularly evident in Africa and the Middle East. Alberta Oil and the Decline of Democracy in Canada sets out to test the “oil inhibits democracy” hypothesis in the context of an industrialized nation in the Global North.In probing the impact of Alberta’s powerful oil lobby on the health of democracy in the province, contributors to the volume engage with an ongoing discussion of the erosion of political liberalism in the West. In addition to examining energy policy and issues of government accountability in Alberta, they explore the ramifications of oil dependence in areas such as Aboriginal rights, environmental policy, labour law, women’s equity, urban social policy, and the arts. If, as they argue, reliance on oil has weakened democratic structures in Alberta, then what of Canada as whole, where the short-term priorities of the oil industry continue to shape federal policy? In Alberta, the New Democratic Party is in a position to reverse the democratic deficit that is presently fuelling political and economic inequality. The findings in this book suggest that, to revitalize democracy, provincial and federal leaders alike must find the courage to curb the influence of the oil industry on governance.

Abstract

China’s road to sustainability has attracted global attention. Since the “Reform & Opening Up” policy, China’s rapid pace of both urbanization and industrialization has made its being the second largesteconomy but meantime a heavy environmental price has been paid over the past few decades for addressing the economic developmental target. Today, as the biggest developing country, China needs to take more responsibilities for constructing its local ecological-civilization society as well as for addressingthe global challenges such as climate change, resources scary and human beings well-fare; therefore, weneed to have deeper understandings into China’s way to sustainability at very different levels, bothspatially and structurally, concerns ranging from generating sustainable household livelihoods to globalclimate change, from developing technological applications to generate institutional changes. In thisspirit, this publication, “Sustainability in China: Bridging Global Knowledge with Local Action” aims to investigate the intended and spontaneous issues concerning China’s road to sustainability in a combined top-down and bottom-up manner, linking international knowledge to local-based studies.
