Federal dams have been the focus of major disputes involving application of the Endangered Species Act (ESA), especially its §7 prohibitions on federal actions causing jeopardy to protected species. Operating agencies and project beneficiaries have sought to keep the ESA from restricting dam operations, including by arguing that such operations are non-discretionary and thus exempt. In proposing new ESA implementing rules, the Trump Administration suggested, but did not formally propose, that ongoing federal actions should be considered part of the “environmental baseline” for §7 purposes.

Prof. Richard L. Revesz and Dr. Burcin Unel provide a useful, albeit no longer current, review of electric energy storage in Managing the Future of the Electricity Grid: Energy Storage and Greenhouse Gas Emissions (Managing). The energy storage market has continued its rapid technical and manufacturing evolution. Those advances may reasonably be expected to impact today’s regulatory aims and frameworks, just as prior technological progress influenced administrative goals and processes.

In their paper, Managing the Future of the Electricity Grid: Energy Storage and Greenhouse Gas Emissions, Richard L. Revesz and Burcin Unel of New York University School of Law (NYU team or authors) highlight a critical (and often times contentious) issue that the energy industry is attempting to address: how to quantify and incorporate a societal value of decreased greenhouse gas emissions into the dollar value of incremental energy that is provided to the electric system.

The view that promoting the use of energy storage systems produces environmentally attractive results has been standard in policy circles. Policymakers have been enthusiastic about energy storage systems primarily because of their belief that cheaper and more prevalent storage options could help facilitate the integration of increased renewable energy generation and speed up the transition to a low-carbon grid. This beneficial outcome, however, is not guaranteed.

There is a movement among companies to use more renewable energy and less energy obtained from fossil fuels. Some are pledging to go “100% renewable,” while many others have set goals to rely on substantial percentages of renewable energy. In addition to setting these goals, many companies report on how much renewable energy they currently use, and convey this information in annual sustainability reports or in publicly issued statements and news releases.

Editors' Summary: In this Article, William W. Wade evaluates the conceptual measurement of economic impact within the Penn Central test for income-producing properties recently adjudicated in the U.S. Court of Federal Claims and U.S. Court of Appeals for the Federal Circuit. The discussion considers measurement of the denominator of the takings fraction related to Penn Central's parcel as a whole and whether it differs between permanent and temporary takings.

In a recent essay, David Coursen asks an important and unexamined question: Are environmental justice policies, which seek to avoid disproportionate environmental burdens on minority and poor communities, on a "collision course" with the Equal Protection Clause? In concluding that a potential collision is more illusory than real, Coursen offers a number of reasons why governmental actions to promote environmental justice have not been challenged in court and, even if they were to be, would not be subjected to strict judicial scrutiny.

Editors' Summary

Editors' Summary: Rather than signaling the death of private property rights, as media and the public initially feared, the Supreme Court decision in Kelo v. City of New London ushered in an era of increased state and federal protection for private property. In this Article, Daniel H. Cole examines Kelo's repercussions for urban redevelopment. He begins with a description of the case, and then examines the resulting backlash from the media and public opinion, which decried the decision as unduly expanding eminent domain powers.

Editor's Summary: The exact contours of wetlands jurisdiction has been in dispute ever since the U.S. Supreme Court's decision in Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers. Today, the Court has been given the chance to clarify this area of law as it faces two cases dealing with wetlands jurisdiction. In Rapanos v. United States, the Court must decide whether CWA jurisdiction extends to a series of wetlands that do not abut a navigable-in-fact water. And in Carabell v. U.S.
