Energy-saving Innovations from EE
During Climate Week NYC, we’re spotlighting some of the ways Columbia Electrical Engineering, students, alumni and faculty are building a greener world. From energy-efficient radiators to renewable energy markets, these four technologies show how breakthroughs in the lab can have a concrete impact in the fight against climate change.
Driving Farther with Less Energy
Electric vehicles lose a lot of energy through inefficient power conversion. Associate Professor Matthias Preindl, has partnered with tech startup Tau Motors to develop next-generation power conversion technologies for the company’s revolutionary automotive platform.

Slashing the Energy Needed to Keep Legacy Buildings Warm
Alumnus Marshall Cox PhD’13 spent his first three winters at Columbia throwing open the window to cool down his boiler-heated dorm room. That experience inspired him to invent a series of products that make steam-powered radiators more energy efficient. The startup he founded on campus, now called Kelvin, recently closed $30 million in Series A funding. The company has retrofitted more than 15,000 buildings across the Northeast.

High-performance Computing without Exponentially Higher Carbon Emissions
Professor Keren Bergman led a team that developed an energy-efficient method for transferring massive quantities of data over fiber-optic cables inside the data centers and high-performance computers that run artificial intelligence programs.
“What this work shows is a viable path towards both dramatically reducing the system energy consumption while simultaneously increasing the computing power by orders of magnitude, allowing artificial intelligence applications to continue to grow at an exponential rate with minimal environmental impact,” Bergman said.

Designing Energy Markets that Balance Low Emissions and Affordable Energy
With wind and solar providing an ever-growing percentage of electricity to the grid, utilities across the country are turning to private companies to store energy when it’s cheap and abundant and sell it when the demand for energy exceeds the supply. These complex and unpredictable energy markets must be designed with a high level of sophistication to benefit society.
