This comprehensive Congress examines the frontiers in the development of optical technologies for energy production, transmission, monitoring and use. This year the use of optical and photonics approaches to monitor both energy usage and the effect of energy production on the environment will be augmented by the addition of topical meetings on Fourier transform spectroscopy and hyperspectral sensing. This Congress is designed to bring together researchers, engineers, and managers to foster timely information exchange between the disciplines involved in these fields.
