From an early age, children spend many hours interacting with screens: phones, tablets, and laptops. A new policy brief from the Child Health Policy Program explains the importance of unstructured free play for healthy child development and recommends four policy approaches to reduce screen time and ensure children’s well-being in the digital age.

Qualities like amazing tensile strength and electrical conductivity offer a huge range of uses for carbon nanotubes. In a new policy brief, fellow Rachel A. Meidl and her co-authors Dana Goerzen and Daniel A. Heller explain that to ensure carbon nanotubes’ role in a circular, sustainable economy, a coordinated system for classifying, testing, and identifying CNTs and a life cycle approach to risk assessments are needed to better understand impacts to facilitate consistent communication among researchers, industries, and policymakers.

Are our views of sustainability becoming distorted by the often unsubstantiated “green” actions of companies and organizations? This brief explores why we urgently need a new framework for sustainability — one that relies on a holistic, cross-disciplinary, and multidimensional life cycle approach.

With the 45V tax credit, the U.S. is well poised to compete for the growing pipeline of clean hydrogen projects globally, writes fellow Rachel Meidl. But if the Treasury adds restrictions to the new tax credit, the U.S. could lose its advantage and a key opportunity for large-scale decarbonization.

It’s been two years since Winter Storm Uri swept across Texas, and the question of whether and how to end the isolation of the state’s grid remains. Nonresident scholar Julie Cohn offers a brief history of the standalone Texas grid to explore how the lessons of the past can inform the state’s electric power future.

As the energy transition continues, the viability of our power system is at stake. Nonresident scholar Julie A. Cohn explains the need to prepare for next-generation grid technology if we are to maintain a stable, economical and secure power system.

Carbon nanotubes are critical components for future decarbonization strategies and a clean energy revolution. If the U.S. is to reestablish climate leadership, advanced nanotechnology solutions must be a national priority, argues the author.

In the transition to a renewable energy future, we must invest in a new transmission infrastructure – some crossing state borders – that connects intermittent power, traditional power and users, write Center for Energy Studies experts.

Integrating a life-cycle dimension into future policies to assess the social, environmental and economic implications of various products across their life cycle and throughout their value chain is critical to achieving sustainability and a circular economy, writes Rachel A. Meidl, fellow in energy and environment.

Energy fellow Rachel A. Meidl writes that it is imperative to consider and assess innovative recycling technologies that could have enormous economic value in transforming waste plastics into the building blocks for new, higher-value products.
