Professor, Columbia University
Modi received his Ph.D. from Cornell University in 1984 and worked as a post-doc at MIT from 1984 to 1986 before joining the faculty at Columbia University. He is past-Chair of Mechanical Engineering in the School of Engineering and Applied Science. Between October 2011 and 2012, he was a member of the U.N. Secretary General’s high-level task force on “Sustainable Energy for All” and he currently leads the U.N. Sustainable Development Solutions Network working group on Energy Access for All.
The three main global energy concerns of providing access to modern energy, enhancing the security of the energy supply, and minimising the impact of energy systems on the climate have an impact on both national and international energy governance. To develop solutions that address the many facets of these difficulties, however, a variety of actors and stakeholders must be included due to the complexity of the energy challenges.
Cities are responsible for more than 70% of the world’s energy consumption and 40% to 50% of its greenhouse gas emissions. Managing increasing urbanisation is a challenge, and nations must deal with the effects it will have on the environment in terms of energy and climate.
Our transition to a future with lower carbon emissions depends heavily on buildings. They are our places of residence, rest, and employment; they also account for around one-third of the world’s greenhouse gas emissions and nearly 40% of the world’s energy usage.
