On his return, Bansal shifted his focus to renewable energy, energy efficiency in buildings, energy planning models, and environmental systems analysis.[10]

Bansal joined the Centre of Energy Studies at IIT Delhi in the year 1979, where he made contributions to the development of the curriculum, laboratories, and collaborative national and international projects,[10] and was elevated to the post of Chief Scientific Officer in 1988 and later to Professor in 1991. He served as the head of the Centre of Energy Studies during 1997-1999 before retiring.

He later returned to Germany, this time at the Research Center Juelich in the field of solar energy, working in the field of solar thermal technologies, energy efficient buildings, and energy economics planning. He wrote the book book The Climate Zones of India and Passive Building Design: A Handbook of Natural Climate Control with G. Minke and G. Hauser, which later became the standard work in the field.[16]

Bansal has served as a board member, member of expert groups, or as a consultant for entities including Sintex Plastics Technology Limited,[17] Tata Consultancy Services,[18] Punjab Agro Industries[19] and Ronak Industries.[20] He also served as consultant to governmental and non-governmental agencies such as the Ministry of Non-Conventional Energy Resources, the Tata Energy Research Institute,[21] the Swedish Energy Development Agency,[22] the Ministry of Economic Cooperation,[23] and the Planning Commission of India and Germany.[24]

After completing his tenure at SMVDU, Bansal returned to Delhi and was invited by the Ministry of New and Renewable Energy as a HR consultant to develop a course curriculum for all national institutions at various levels. Simultaneously, he was offered an industry chair, Sintex Chair Professor,[25] at CEPT University[26] with the option to operate from Delhi, a position he accepted and remained in until his retirement in May, 2019.
