CalCEF was created to solve a problem. Despite significant environmental policy leadership, until recently the private sector - particularly the financial community - has lagged in making investments in clean energy companies, creating a gap in the commercialization of new energy technologies. The core problem of energy is technological in nature, and we cannot afford to leave fundamental innovations unsupported at a crucial juncture in their development. CalCEF was created to focus expertise and financial resources on this aspect of the energy challenge.
The first CalCEF investment vehicle, CalCEF Fund I, employs an innovative nonprofit “fund-of-funds” model to achieve broad diversification in its portfolio. In this Fund, CalCEF is an active, strategic limited partner in three established venture funds.
In 2008 CalCEF launched its second investment vehicle, the CalCEF Clean Energy Angel Fund I, to focus capital and entrepreneurial support at the earliest stages of company formation.
