How to Globalize Clean Energy

| June 20, 2020

The authors argue that more determined efforts to globalize renewable energy transmission can confer significantly higher economic and environmental benefits from renewables on billions of people. This can be done by exploiting spatial differences between electricity loads and net renewable generation across time zones (temporal arbitrage) and latitude (seasonal arbitrage). Using very long distance, ultra-high voltage (UHV) transmission infrastructure, temporal and spatial arbitrage can move low-cost clean electricity from areas with excess capacity to high demand zones in other countries and even continents.

Urban Waste to Energy Recovery Assessment Simulations for Developing Countries

In this paper, a quantitative Waste to Energy Recovery Assessment (WERA) framework is used to stochastically analyze the feasibility of waste-to-energy systems in selected cities in Asia.

Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.

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.

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

| 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.

| October 2017

Electric drive vehicles are equipped with totally different propulsion systems compared with conventional vehicles, for which the energy consumption and cradle-to-gate greenhouse gas emissions associated with vehicle production could substantially change. In this study, the life cycle energy consumption and greenhouse gas emissions of vehicle production are compared between battery electric and internal combustion engine vehicles in China's context.

How International Cooperation in Research Advances Both Science and Diplomacy

| Apr. 27, 2017

"The partial budget blueprint released by the White House recently will put U.S. leadership in science and technology at serious risk if Congress goes along. In addition to the obvious damage that would result from the proposed $5.8 billion cut at NIH, the $2 billion cut in applied energy R&D, the $900 million cut in DOE’s Office of Science, the abolition of ARPA-E, and the research cuts at NOAA and EPA, a less immediately obvious potential casualty would be U.S. scientific cooperation with a wide variety of other countries on a wide variety of topics."
