InterTubes: A Study of the US Long-haul Fiber-optic Infrastructure

Friday, September 25th, 2015
Figure 1: Location of physical conduits for networks considered in the continental United States

The complexity and enormous costs of installing new long-haul fiber-optic infrastructure has led to a significant amount of infrastructure sharing in previously installed conduits. In this paper, we study the characteristics and implications of infrastructure sharing by analyzing the long-haul fiber-optic network in the US.

GREENPEACEIntroductionThe good news first: the Energy [R]evolution is already happening! Since the first edition was published in 2005, costs for wind power and solar photovoltaics (Pv) have dropped dramatically and markets have grown substantially. Between 2005 and the end of 2014 over 496,000 MW of new solar and wind power plants have been installed – […]

U.S. DOT: Using GPS For Transportation Research

These days GPS makes a transportation planner’s research effort much easier. Until now access to the data created wasn’t so easy. Watch the video to see how FHWA’s Office of Planning, Environment and Realty’s Research Program teamed with U.S. Department of Energy’s National Renewable Energy Laboratory to access secure travel data on the web.

Promoting Electric Vehicles in U.S. Cities

Wednesday, September 9th, 2015
Figure ES-1. Electric vehicle promotion actions, charging infrastructure, and electric vehicle share of new vehicles in 2014 in the 25 most populous U.S. metropolitan areas (2014 electric vehicle registration data provided by IHS Automotive)

Cities could represent an important focal point in the transition toward a robust electric vehicle market due to urban driving patterns and cities’ concentration of vehicle ownership and charging networks. Although it is early in what is likely a decades-long transition toward an electric-drive vehicle fleet, the current diversity of electric-drive promotion actions provides a rich laboratory for what is working.

Cool Solutions: New Technology to Fight Climate Change in Massachusetts

Tuesday, September 1st, 2015
Figure ES-1. Historical Greenhouse Gas Emissions and Trajectories Needed to Achieve 2020, 2030 and 2050 Emission Reduction Targets

To ensure that the Commonwealth stays on track to meet its target under the Global Warming Solutions Act of cutting emissions by at least 80 percent by 2050, Massachusetts should adopt a target of reducing greenhouse gas emissions to at least 45 percent below 1990 levels by 2030…Achieving that goal will require Massachusetts to fully implement previous commitments to reduce global warming pollution. It will also require us to take full advantage of a new wave of game-changing opportunities – from cutting-edge technologies to emerging societal trends – that can help Massachusetts build on its position of national leadership in the fight against global warming.

Wilsonville, OR: Aerial Inspection of the Baldock Solar Station

Earlier this summer, the Oregon Department of Transportation participated in an aerial inspection of the solar panels at the Baldock Solar Station Array. The inspection was performed by Aerial Inspection Resources, who flew a drone equipped with a high resolution infrared camera that can detect malfunctioning solar cells by the extra heat they emit. PGE owns the nearly 7,000 panel array that is located at the French Prairie Rest Area, south of Wilsonville, and was interested in seeing how they could save time and manpower by inspecting the panels with this type of system.

Wind Technologies Market Report

Friday, August 21st, 2015
Figure 1. Annual and cumulative growth in U.S. wind power capacity

Annual wind power capacity additions in the United States rebounded in 2014, and continued growth through 2016 is anticipated. Recent and projected near-term growth is supported by the industry’s primary federal incentive—the production tax credit (PTC)—which is available for projects that began construction by the end of 2014. Wind additions are also being driven by recent improvements in the cost and performance of wind power technologies, which have resulted in the lowest power sales prices ever seen in the U.S. wind sector.
