More Climate Change Recognition, Action Among Major Investors

| May 10, 2018

Since the Paris Agreement's adoption in 2015, a majority of the world's largest investors have begun to take action on climate change. According to a new report, the 2016–2017 year showed an average improvement in decarbonization within all major investor categories except pension funds.

Climate, Air Quality and Human Health Benefits of Various Solar Photovoltaic Deployment Scenarios in China in 2030

Solar photovoltaic (PV) electricity generation can greatly reduce both air pollutant and greenhouse gas emissions compared to fossil fuel electricity generation. The Chinese government plans to greatly scale up solar PV installation between now and 2030. However, different PV development pathways will influence the range of air quality and climate benefits. Benefits depend on how much electricity generated from PV is integrated into power grids and the type of power plant displaced. Using a coal-intensive power sector projection as the base case, the authors estimate the climate, air quality, and related human health benefits of various 2030 PV deployment scenarios.

The Politics of Shale Gas in Eastern Europe: Energy Security, Contested Technologies and the Social Licence to Frack

| May 2018

Fracking is a novel but contested energy technology – so what makes some countries embrace it whilst others reject it? This book argues that the reason for policy divergence lies in procedures and processes, stakeholder inclusion and whether a strong narrative underpins governmental policies. Based on a large set of primary data gathered in Poland, Bulgaria and Romania, it explores shale gas policies in Central Eastern Europe (a region strongly dependent on Russian gas imports) to unveil the importance of policy regimes for creating a 'social license' for fracking. Its findings suggest that technology transfer does not happen in a vacuum but is subject to close mutual interaction with political, economic and social forces; and that national energy policy is not a matter of 'objective' policy imperatives, such as Russian import dependence, but a function of complex domestic dynamics pertaining to institutional procedures and processes, and winners and losers.

Recycling-Based Reduction of Energy Consumption and Carbon Emission of China's Electric Vehicles: Overview and Policy Analysis

Electric vehicles maintain the fastest development in China and undertake the responsibility of optimizing energy consumption and carbon emission in the transportation field. However, from the entire life cycle point of view, although electric vehicles have a certain degree of energy consumption and carbon emission reduction in the use phase, they cause extra energy consumption and carbon emission in the manufacturing phase, which weakens the due environmental benefits to some extent. The recycling of electric vehicles can effectively address the issue and indirectly reduce the energy consumption and carbon emission in the manufacturing phase. China is setting up the recycling system and strengthening regulation force to achieve proper energy consumption and carbon emission reduction benefits of electric vehicles.

Potential Co-benefits of Electrification for Air Quality, Health, and CO2 Mitigation in 2030 China

    Authors:

| May 15, 2018

Electrification with decarbonized electricity is a central strategy for carbon mitigation. End-use electrification can also reduce air pollutant emissions from the demand sectors, which brings public health co-benefits. In this article, the authors focus on electrification strategies for China, a country committed to both reducing air pollution and peaking carbon emissions before 2030. Considering both coal-intensive and decarbonized power system scenarios for 2030, they assess the air quality, health, and climate co-benefits of various end-use electrification scenarios for the vehicle and residential sectors relative to a non-electrified coal-intensive business-as-usual scenario.

Towards Sustainability in Water-energy Nexus: Ocean Energy for Seawater Desalination

In this article, the authors review the state of the art of ocean energy in desalination. It explores different sources of energy from the ocean that include electricity generation, as well as mechanical force and thermal energy and salinity gradients that can also be directly harnessed for powering the desalination processes. They also examine recent advances in scaling up for commercial deployment and discuss relevant cost, environmental, and social concerns.

Policy Sequencing toward Decarbonization

| November 2017

Many economists have long held that carbon pricing—either through a carbon tax or cap-and-trade—is the most cost-effective way to decarbonize energy systems, along with subsidies for basic research and development. Meanwhile, green innovation and industrial policies aimed at fostering low-carbon energy technologies have proliferated widely. Most of these predate direct carbon pricing. Low-carbon leaders such as California and the European Union (EU) have followed a distinct policy sequence that helps overcome some of the political challenges facing low-carbon policy by building economic interest groups in support of decarbonization and reducing the cost of technologies required for emissions reductions. However, while politically effective, this policy pathway faces significant challenges to environmental and cost effectiveness.

Reduction of Solar Photovoltaic Resources Due to Air Pollution in China

Enormous growth in solar photovoltaic (PV) electricity generation in China is planned, with a goal to provide 10 perecnt of total electricity demand by 2030. However, over much of China, aerosol pollution scatters and absorbs sunlight, significantly reducing surface solar radiation suitable for PV electricity generation. The authors evaluate the impact of aerosols on PV generation and find aerosol-related annual average reductions in eastern China to be more than 20 percent. In winter, aerosols have comparable impacts to clouds over eastern provinces. Improving air quality in China would increase efficiency of solar PV generation. As a positive feedback, increased PV efficiency and deployment would further reduce air pollutant emissions as well.
