Many refugee camps exist for decades but associated infrastructure needs are only planned for the very short term, including provision of power. This study advocates a shift in approach to sustainable electrification of essential services in refugee camps for lighting, refrigeration, health, water, education, alongside camp operations. Qualitative and quantitative surveys were conducted in refugee camps in Uganda and Bangladesh which assessed the electrical supply needs across such categories.

A validated numerical model of tidal flows and sediment transport around the Alderney South Banks was used to investigate the potential effects of large (300 MW) tidal turbine arrays at different locations in Alderney territorial waters. Two methods were used, firstly looking at hydrodynamic changes only and secondly modelling sediment transport over a non-erodible bed. The baseline hydrodynamic model was validated relative to ADCP velocity data collected in the immediate vicinity of the sandbank.

This research provides an updated energy yield assessment for a large tidal stream turbine array in the Alderney Race. The original array energy yield estimate was presented in 2004. Enhancements to this original work are made through the use of a validated two-dimensional hydrodynamic model, enabling the resolution of flow modelling to be improved and the impacts of array blockage to be quantified.
