Energy Use in the U.S. Food System

Energy is an important input in growing, processing, packaging, distributing, storing, preparing, serving, and disposing of food. Analysis using the two most recent U.S. benchmark input-output accounts and a national energy data system shows that in the United States, use of energy along the food chain for food purchases by or for U.S. households increased between 1997 and 2002 at more than six times the rate of increase in total domestic energy use. This increase in food-related energy flows is over 80 percent of energy flow increases nationwide over the period.

Comprehensive evaluation of effects of straw-based electricity generation: A Chinese case

Greater use of renewable energy is being aggressively promoted to combat climate change by the Chinese government and by other governments. Agricultural straw is the kind of renewable energy source that would become a pollution source if it is not well utilized. We select the Shiliquan straw-based electricity generation project in Shandong Province, China as a case and assess environmental externalities of straw utilization in power plants by using life-cycle analysis.

Antagonistic bioenergies: Technological divergence of the ethanol industry in Brazil

We present evidence for the coexistence of two antagonistic sugarcane ethanol production technologies in Brazil, with the Southeast region of the country having relatively mechanized production processes, and the Northeast area using labor-intensive ones.We highlight the main differences between the handproduction and fully automated mechanicalmanufacturing in the Brazilian ethanol industry and examine the historical, political, and economic factors that induced this regional technology gap that is currently observed.

Land Recycling in China and its Implication for the Regional Economy

Since 2000, many cities in China have moved their large-scale manufacturing plants from urban to suburban or other less-developed regions. This inter- or intra-regional plant relocation not only leads to changes in land use patterns but also affects institutional, socioeconomic, and environmental issues both at the local and regional levels. We call this regional restructuring process land recycling, which creates critical energy, environmental,  financial, social, and political implications.

Measuring the energy consumption of China’s domestic investment from 1992 to 2007

In this study, we first define the energy consumption of domestic investment as the investment-driven energy consumption (IDEC). Then, we build an energy input–output model to identify quantitatively the amounts of China’s IDEC from 1992 to 2007. We also use the model to analyze the sector distributions of the IDEC for the same time period.

Measuring the energy consumption of China’s domestic investment from 1992 to 2007

In this study, we first define the energy consumption of domestic investment as the investment-driven
energy consumption (IDEC). Then, we build an energy input–output model to identify quantitatively
the amounts of China’s IDEC from 1992 to 2007. We also use the model to analyze the sector distributions
of the IDEC for the same time period. The key findings derived from this study improve the understanding
of the effects of China’s domestic investment on its energy consumption expansion and reflect the fact

What Works for Green Cities

In cities across the country, bike-sharing plans, tree-planting initiatives, and other programs aimed at enhancing urban sustainability are becoming increasingly popular. As mayors consider how to design and implement their own programs, they can turn for guidance to a series of MIT assessments of what kinds of programs have worked — and not worked — in other cities and why. The MIT director of the assessment project is now developing a systematic, user-friendly method of presenting this information as well as a protocol that will permit easy or even automatic updating of the content.
