This article contributes to the understanding of transitions towards low carbon societies in the developing world. While adding extensive empirical insights from the status of energy transitions in two countries faced with major energy challenges, the Philippines and Morocco, the authors contribution enquires what role external actors like international donors in general, and Germany in particular, can play in such transitions.

Extracting, delivering, and disposing water requires energy, and similarly, many processes for extracting and refining various fuel sources and producing electricity use water. This so-called 'water–energy nexus', is important to understand due to increasing energy demands and decreasing freshwater supplies in many areas. This paper performs a country-level quantitative assessment of this nexus in the MENA region.

Recent national trends in investments in global energy research, development, and demonstration (RD&D) are inconsistent around the world. Public RD&D investments in energy are the metric most commonly used in international comparative assessments of energy-technology innovation, and the metric employed in this article. Overall, the data indicate that International Energy Agency (IEA) member country government investments have been volatile: they peaked in the late 1970s, declined during the subsequent two decades, bottomed out in 1997, and then began to gradually grow again during the 2000s.

"Without energy, there is no economy. Without climate, there is no environment. Without economy and environment, there is no material well-being, no civil society, no personal or national security. The overriding problem associated with these realities, of course, is that the world has long been getting most of the energy its economies need from fossil fuels whose emissions are imperiling the climate that its environment needs."

Sectoral approaches have been gaining currency in the international climate debate as a possible remedy to the shortfalls of the Kyoto Protocol. Proponents argue that a sector-based architecture can more easily invite the participation of developing countries, address competitiveness issues, and enable immediate emissions reductions. However, given the numerous proposals, much confusion remains as to what sectoral approaches actually are. This article provides a simple, yet comprehensive, taxonomy of the various proposals for sectoral approaches.

As the Biofuel industry surges with investments and new entrepreneurial players, Kennedy School scholars are analyzing it working to develop new ways to create carbon-neutral fuels. Madeline Drexler writes on the Kennedy School's input on this emerging new way to lower greenhouse gas emissions and become less dependent on non-renewable energy resources.

"I would urge every scientist and engineer with an interest in the intersection of S&T with sustainable well-being...to 'tithe' 10% of your professional time and effort to working in these and other ways to increase the benefits of S&T for the human condition and to decrease the liabilities. If so much as a substantial fraction of the world's scientists and engineers resolved to do this much, the acceleration of progress toward sustainable well-being for all of Earth's inhabitants would surprise us all."
