"Even when you have great technology, you need some incentive for people to reduce pollution. We need to find ways to make the benefit of reducing pollution felt by the ones who are paying the cost of reducing pollution." —Ariel Zucker, MIT doctoral student in economics

Incentives matter

Working with the Tata Center, two MIT economics students are testing projects to reduce industrial pollution in India.

This GridForm model of a village in Bihar, India, shows the optimal layout of hardware for the load profiles of the community. Each building, color-coded by the cost (in Indian rupees) of supplying electricity to that structure, is wired to a central generation/storage node (solid lines), and the nodes are connected to each other (dotted lines).

A proof-of-concept device built by MIT researchers demonstrates the principle of a two-stage process to make incandescent bulbs more efficient. This device already achieves efficiency comparable to some compact fluorescent and LED bulbs.

A nanophotonic comeback for incandescent bulbs?

Researchers combine the warm look of traditional light bulbs with 21st-century energy efficiency.

Manu National Park, a large (15,328-square-kilometer) protected area in southeastern Peru, includes several ecological zones and spans an elevation range of 150-4,200 meters above sea level. Manu’s vast tracks of Amazonian rainforest are part of the global tropical forest carbon sink that is slowing the rate of increase in atmospheric carbon dioxide, a primary driver of climate change.

Assessing nature's carbon sinks

Study estimates the annual carbon sequestration rate in protected areas such as rainforests will decline by about 40 percent between now and 2100.
