New Technologies and Strategies to Cut Down Emissions

Wednesday, November 11th, 2015
Figure 2. Share of Ride-Sharable Trips Relative to Total Trips by Scenario

MINETA TRANSPORTATION INSTITUTE Executive Summary It is widely recognized that new vehicle and fuel technology is necessary, but not sufficient, to meet deep greenhouse gas (GHG) reductions goals for both the U.S. and the state of California. Demand management strategies (such as land use, transit, and auto pricing) are also needed to reduce passenger vehicle […]

2015 State Energy Efficiency Scorecard

Thursday, October 22nd, 2015
Figure ES1. 2015 State Scorecard rankings

AMERICAN COUNCIL FOR AN ENERGY-EFFICIENT ECONOMY
In this ninth edition of our State Energy Efficiency Scorecard, the American Council for an Energy-Efficient Economy (ACEEE) ranks states on their policy and program efforts and recommends ways that states can improve their energy efficiency performance in various policy areas. The State Scorecard provides an annual benchmark of the progress of state energy efficiency policies and programs. It encourages states to continue strengthening their efficiency commitments in order to promote economic growth, secure environmental benefits, and increase their communities’ resilience in the face of the uncertain cost and supply of the energy resources on which they depend.

Shared Solar: Current Landscape, Market Potential, and the Impact of Federal Securities Regulation

Wednesday, October 14th, 2015
Figure ES-1. Estimated PV market potential of onsite and shared solar distributed PV capacity

NATIONAL RENEWABLE ENERGY LABORATORY
This report provides a high-level overview of the current U.S. shared solar landscape and the impact that a given shared solar program’s structure has on requiring federal securities oversight, as well as an estimate of market potential for U.S. shared solar deployment. Shared solar models allocate the electricity of a jointly owned or leased system to offset individual consumers’ electricity bills, allowing multiple energy consumers to share the benefits of a single solar array. Despite tremendous growth in the U.S. solar market over the last decade, existing business models and regulatory environments have not been designed to provide access to a significant portion of potential PV system customers.

How Americans Charge Their Plug-In Vehicles

Monday, October 5th, 2015
Figure 3-1. Areas where public charging infrastructure was installed and vehicles were enrolled in The EV Project and ChargePoint America Project.

IDAHO NATIONAL LABORATORY
The answer is clear: despite installation of extensive public charging infrastructure, in most of the project areas, the vast majority of charging was done at home and work. About half The EV Project participants charged at home almost exclusively. Of those who charged away from home, the vast majority favored three or fewer away-from-home charging locations, with one or more of these locations being at work for some drivers.

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

ASSOCIATION FOR COMPUTING MACHINERY
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.

U.S. DOT: Using GPS For Transportation Research

Friday, September 18th, 2015

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)

INTERNATIONAL COUNCIL ON CLEAN TRANSPORTATION (ICCT)
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.

Dear Friends,

 

It is encouraging to finally see clear signs of federal action to support a comprehensive US infrastructure investment plan.

 

Now more than ever, our advocacy is needed to keep stakeholders informed and connected, and to hold politicians to their promises to finally fix our nation’s ailing infrastructure.

 

We have already engaged nearly 280,000 users, and hoping to add many more as interest continues to grow.

 

We require your support in order to rise to this occasion, to make the most of this opportunity. Please consider making a tax-deductible donation to InfrastructureUSA.org.
