The second edition of the Cogeneration Day USA took place in California, and as moderator of the event Jennifer Kefer reminds us, it was an educational and very stimulating day. According to data provided during the conference, there is room for growth both for cogeneration and biogas, as well as other renewable sources that can be integrated into cogeneration. Another important aspect that emerged from the event is the many tools to finance new projects; despite the fact that processes for obtaining permits are not obstacle-free, there are professionals able to overcome them. Next year's event will be held on the east coast.
