INTERSTATE RENEWABLE ENERGY COUNCIL (IREC)
In recent years, new technologies have emerged on the customer side of the electric system, including distributed energy resources (DER) such as distributed generation, energy efficiency, electric vehicles, energy storage and demand response technologies, among others. These technologies are allowing growing numbers of energy consumers to decrease their electricity demand, act as energy producers and otherwise manage their energy usage…Together, these compounding factors have driven the movement toward a more modern grid that enables significant increases in the amount of clean energy produced; universal consumer access and facilitation of consumer choice, including the adoption of DER; integrated resource planning; two-way flow of energy and information; and increased reliability, security and resiliency.

Easing the Transition to a More Distributed Electricity System

Thursday, March 5th, 2015![Figure 1: A Streetcar in Portland, Oregon](https://www.infrastructureusa.org/wp-content/uploads/2015/03/streetcarsfig1.jpg)
MINETA TRANSPORTATION INSTITUTE
This study examines the transportation performance of modern-era streetcars operated in five U.S. cities: Little Rock, Memphis, Portland, Seattle, and Tampa. The objective of the study is to examine streetcar performance, test hypotheses about variation in performance through a combination of empirical analysis and insights derived from key informant interviews, and to identify lessons for other cities that operate or are contemplating operating streetcars
Funding Challenges in Highway and Transit
Wednesday, March 4th, 2015![All Levels of Government Fund Highways and Transit](https://www.infrastructureusa.org/wp-content/uploads/2015/03/pew-Figure1.jpg)
THE PEW CHARITABLE TRUSTS
With the temporary increase in funding for the federal highway trust fund set to run out by May 2015, states and localities are again facing the prospect that shortfalls in the fund could delay or reduce the federal money they rely on for transportation projects. As they wait to see what federal policymakers will do, many states are taking action to make their own transportation funding more sustainable. These efforts highlight the major challenges that all levels of government face in maintaining investments in highways and transit systems—problems that will require policymakers to make difficult choices in the years ahead.
Iowa Infrastructure: ASCE 2015 Report Card
Tuesday, March 3rd, 2015![Iowa Infrastructure Report Card 2015](https://www.infrastructureusa.org/wp-content/uploads/2015/03/iowainfra.jpg)
AMERICAN SOCIETY OF CIVIL ENGINEERS
IOWA SECTION
The 2015 Report Card for Iowa’s Infrastructure has been prepared to acquaint Iowans with the extent, condition and importance of the capital assets that support modern life. It is hoped that this information, along with the grades, will encourage awareness of and concern for these often under-appreciated facilities. Iowa’s ASCE members hope that the grades will alert citizens, media agencies, business leaders, and elected officials to the needs of the infrastructure and induce a commitment to giving it proper care and upkeep.
Skills and Innovation Strategies to Strengthen U.S. Manufacturing
Monday, March 2nd, 2015![Table 1. Germany vs. the United States on Key Economic Indicators](https://www.infrastructureusa.org/wp-content/uploads/2015/03/germanyvsusa.jpg)
BROOKINGS INSTITUTION
METROPOLITAN POLICY PROGRAM
Germany is an oft-cited example of an advanced economy that has been able to sustain manufacturing as a relevant source of employment, growth, and exports. Manufacturing in Germany accounts for 20 percent of employment, nearly twice the share as in the United States, and generates 22 percent of national GDP and 82 percent of total goods exports. German manufacturing succeeds in the global marketplace even as the sector pays higher average wages than in the United States.
Portland Metro: How Much Travel-Time Reliability Matters
Friday, February 27th, 2015![Figure 1.1. Overall model framework.](https://www.infrastructureusa.org/wp-content/uploads/2015/02/modalframework.jpg)
TRANSPORTATION RESEARCH BOARD
More than 10 scenarios were identified and modeled in this project. The analysis results indicate that both bus rapid transit and variable message signs contribute to improved reliability for the Southwest Corridor when the performance over multiple modes and facilities is being considered. Bus rapid transit contributes to improved corridor performance by increased ridership due to higher reliability, and variable message signs contribute to improved corridor reliability by balancing the arterial and freeway flow via information dissemination.

OHIO DEPARTMENT OF TRANSPORTATION
Changing cultural preferences for transportation are evident from both younger (millennials) and older generations (baby boomers). A large portion of these populations express a desire to live in communities that are bikeable, walkable and have transit.
Wind Energy Helps Build a More Reliable and Balanced Electricity Portfolio
Wednesday, February 25th, 2015![U.S. Wind Energy Share of Electricity Generation by State During 2013](https://www.infrastructureusa.org/wp-content/uploads/2015/02/windenergybystate.jpg)
AMERICAN WIND ENERGY ASSOCIATION
Some of the most common questions about wind energy focus on how wind can be reliably integrated into the power system. A key source of confusion is that, contrary to most people’s intuitive experience that winds are variable and electricity demand and supply is stable, the opposite is actually true at the grid operator scale. The following report answers 15 of the most frequently asked questions with lessons learned from grid operators’ experiences reliably integrating large amounts of wind. Concise answers to these questions are provided here in the executive summary, while citations and explanations of the supporting data and analysis for those answers can be found by following the hyperlinks to the relevant sections of the full report below.
Iowa’s Top Transportation Challenges
Friday, February 20th, 2015TRIP
Iowa must improve its system of roads, highways and bridges to foster economic growth and keep businesses in the state. In addition to economic growth, transportation improvements are needed to ensure safe, reliable mobility and quality of life for all residents. Meeting Iowa’s need to modernize and maintain its system of roads, highways and bridges will require a significant boost in local, state and federal funding.
Fuel Cell Buses in U.S. Transit Fleets
