and consumers have grown to expect advanced functionality even in simple devices. Much of this built-in product complexity comes from electrification: components that are powered, actuated, sensed, and controlled with electrical and electronic technologies. Every day, ultra-competitive product development organizations create ever-more-innovative devices to meet demand. These products deliver m...

Energy harvesting from ambient water motions is a desirable but underexplored solution to on-site energy demand for self-powered electronics. Here we report a liquid-solid electrification-enabled generator based on a fluorinated ethylene propylene thin film, below which an array of electrodes are fabricated. The surface of the thin film is charged first due to the water-solid contact electrific...

Energy efficiency is one of the key factors affecting energy consumption and greenhouse gas (GHG) emissions. By focusing on China’s transport sector, this study comprehensively reviews and compares the energy efficiency performance of passenger vehicles, light-duty commercial vehicles, commercial road transport, commercial water transport, aviation transport and railway transport, and identifie...

Infrastructure planning for networked infrastructure such as grid electrification (or piped supply of water) has historically been a process of outward network expansion, either by utilities in response to immediate economic opportunity, or in response to a government mandate or subsidy intended to catalyze economic growth. While significant progress has been made in access to grid electricity ...

How do governments distribute basic public services when budget constraints necessitate their rationing? This paper examines variations in the distribution of scarce electrical power in northern India over the last two decades. Drawing on a novel set of satellite imagery of the earth at night that avoids the biases and missing data problems affecting traditional measures, I construct annual ind...

Abstract: During recent years, optimal electrification of isolated offshore systems has become increasingly important and received extensive attention from the maritime industry. Especially with the introduction of electric propulsion, which has led to a total electrification of shipboard power systems known as all-electric ships (AESs), the need for more cost-effective and emission-aware solut...
