    Comparison of Outlooks and Implications for Energy Transition

    No full text
    The global economy is experiencing a transition from high-carbon energy resources to low-carbon resources. To shed light on the trajectory of the future energy system, we compare three influential outlooks made by the International Energy Agency (IEA), BP and the Energy Information Administration (EIA) of the US Department of Energy. Ultimately an energy transition is determined by technology and economics, but influenced by government policies. We highlight two technological challenges affecting the speed and scope of renewables penetration in the transportation and electric power sector. Our analysis about the total cost of driving indicates that at the current levels of battery prices and vehicle efficiency, only short-range electric vehicles can be cost-competitive with internal combustion engine vehicles when the crude oil price is above $64/bbl. By contrast, wind and solar photovoltaics are becoming increasingly cost-competitive with natural gas in electric power generation. Yet the intermittency issue remains a challenge, since it requires a high level of back-up power and a large quantity of ramp-up resources.</p

    Chinese Women at the Forefront of Environmental Activism: Wang Yongchen, Liao Xiaoyi and Tian Guirong.

    All around the world, women have been at the forefront of environmental activism. In the Western world, very little is known about China’s environmental movement and its champions. This paper aims to bridge this gap. It does so by tracing the path to activism of three female figures: Wang Yongchen, Liao Xiaoyi and Tian Guirong. For each of the three, I first introduce the main environmental campaigns and I then sketch out a profile of the activist, shedding light on their personal motivations, the rhetorical strategies they employ to spur collective action, and their vision for a greener China. The paper has a twofold result: it not only provides the reader with the elements to understand the country’s struggle for sustainability, it also sheds lights on the different manifestations of environmental activism “made in China”. Findings draw mainly from the analysis of secondary sources (books, academic papers, newspaper articles) and to a lesser extent, from first hand interviews carried out by the author between July and December 2013
