Many of the more than 200 remote communities in Alaska are turning to renewable energy to reduce reliance on high-cost imported fuels, and to ensure more independent and reliable energy availability based on local sources. Alaska is home to a substantial fraction of the developed microgrids in the world. Incorporating grid-scale levels of renewably sourced generation, such as wind and solar power, has led to an unusual concentration of experience and expertise in the design, development, and operation of these hybrid renewables-diesel microgrids.

Cities plagued with terrible traffic problems may be overlooking a simple, low-cost solution: High-occupancy vehicle (HOV) policies that encourage carpooling can reduce traffic drastically, according to a new study co-authored by MIT economists.

Naturally occurring algae on Greenland’s massive ice sheet absorb large amounts of the sun’s energy and speed up the melting of the ice sheet even more than black carbon and mineral dust, according to a new study.

Las ciudades plagadas de terribles problemas de tráfico pueden estar pasando por alto una solución simple y de bajo costo: las políticas de vehículos de alta ocupación (HOV) que fomentan el uso compartido de automóviles pueden reducir el tráfico drásticamente, según un nuevo estudio en coautoría de economistas del MIT.

Short-term exposures to fine particulate air pollution and ozone—even at levels well below current national safety standards—were linked to higher risk of premature death among the elderly in the U.S. according to a new study from Harvard T.H. Chan School of Public Health.

The risk was even higher among elderly who were low-income, female, or Black.

The study was published December 26, 2017 in the Journal of the American Medical Association (JAMA).
