Solar energyEdit

A Gross company, Energy Innovations, is working on development of a rooftop concentrated photovoltaic solar collector for flat-roofed commercial buildings. They completed the world's largest corporate solar installation at Google's headquarters in 2006.[5][6]

During 2010, Gross was the CEO of eSolar, a company that aims to make renewable energy cost-competitive with fossil fuel energy using CSP technology. eSolar builds an individual 46 MW power unit on 200 acres and can scale up to 500 MW or larger capacity with multiple units. The company has an order for a 100MW plant in India (in production) and a 500MW plant in China (forthcoming).[citation needed]
