Xi Lu is a PhD candidate in the School of Engineering and Applied Sciences at Harvard University. He works in the energy research group led by Prof. Michael McElroy, and his major research involves meteorology-related renewable energy sources including wind and solar power. Currently he is working on technological and economic potentials for wind energy, variational issues of wind-generated electricity and its compensation with solar power to mitigate the impacts on transmission grid. One of his recent papers about potential for wind-generated electricity in China has been published in Science as a front cover story. Xi Lu is also interested to study the influence of climate change on the future wind resources, with a broader interest in energy problems in low-carbon economy and climate change. He is a member of the first Graduate Consortium on Energy and Environment at Harvard and awarded with fellowship. He got his bachelor and master degree in Environmental Science and Engineering from Nankai and Tsinghua University respectively. Before entering Harvard, Xi Lu worked for CH2M-HILL as environmental scientist and was involved in the environmental consulting projects for Beijing 2008 Olympic Games and for the many multinational clients in the energy industry.
