Replacing conventional building boilers with electric heat pumps in New York City buildings could substantially increase the viability of renewable energy use in the city, according to a recent study from researchers from the Earth Institute’s Sustainable Engineering Lab.
Earth Institute students took a hard look into financial and administrative problems plaguing the MTA and Port Authority of New York and New Jersey, and came up with suggestions for more sustainable financing and more efficient operations.
Earth Institute students evaluated Kentucky’s physical, economic and cultural resources to identify ways to move the economy toward a more sustainable future—and to make recommendations for how the state’s community and technical college system could help.
Students from the Earth Institute’s Sustainability Management and Environmental Science and Policy master’s programs once again demonstrated the broad range of applications for interdisciplinary approaches to sustainable development in their Spring 2014 team capstone projects. The projects provided analysis and recommendations to a range of clients on diverse, real-world sustainability challenges.

As environmentalists have pushed for greater investment in wind and solar energy, critics have insisted that renewable sources of power could never provide more than a fraction of world energy demand. Evidence is mounting, however, that the critics are wrong.
The impact of climate change on New York City could be even more severe than previously thought, putting more people at risk from increasingly frequent floods and heat waves, according to a report by the New York City Panel on Climate Change that was released Monday.
