"Modelling Tidal Renewable Energy Schemes as Building Blocks in a Low Carbon Society"There is an ever present need to find renewable sources of energy and reduce CO2 emissions, which represent the largest contributor to global warming. The United Kingdom as most countries worldwide currently produces large amounts of CO2 to generate energy therefore it is becoming increasingly imperative that new ways of providing power are developed and put into place.
Large scale tidal renewable energy schemes could play an important role in meeting these CO2 reduction aims. Like all hydro power schemes they have a variety of economic and ecological effects on their surroundings. It is therefore necessary to use models that can integrate these effects and sometimes conflicting requirements of different users and stakeholders in the evaluation and planning process of such projects.
In this case study an input-output (Leontief-) model has been applied to proposed tidal barrage options on the Severn Estuary. To evaluate how a tidal barrage could be integrated in a low carbon society scenario, larger scale input output models were set up which included other renewable energy resources and pump storage.
The proposed model is likely to assist materially in the understanding and management of tidal energy schemes and their interaction with society and their environment.
