I want to know the answer to the following question:
Who is a professor of civil and environmental engineering at Stanford University?
All the background I'm provided with is that "Mark Z. Jacobson, professor of civil and environmental engineering at Stanford University and director of its Atmosphere and Energy Program says producing all new energy with wind power, solar power, and hydropower by 2030 is feasible and existing energy supply arrangements could be replaced by 2050.". Is that enough to answer the question?
Answer: yes
