A New Epoch For Community Renewable Energy Co-Operatives In Ireland? An Exploration Of The Factors Influencing Their Development, Gerard Doyle

Articles

The paper outlines the capacities required for community groups to successfully establish and maintain renewable energy co-operatives in Ireland. The paper finds that community groups that successfully establish renewable energy co-operatives must possess high levels of resilience, have access to technical expertise, and have appropriate finance. It also highlights how it is crucial that at least one member of each renewable energy co-operative engages with state agencies and the community. Pringle’s (2015) theoretical framework applied in this paper focuses on the capacities required for the successful implementation of community renewable energy projects (which include community renewable energy co-operatives) in rural …

A New Era For Reuse Social Enterprises In Ireland? The Capacities Required For Achieving Sustainability, Gerard Doyle

Articles

The conventional linear relationship between production and consumption is no longer sustainable. A key component of the transition towards a more sustainable society is the continuation in use of products for longer and the development of a repair and reuse culture. Reuse social enterprises contribute to addressing a range of environmental, economic and social issues facing urban areas. This paper is concerned with, firstly, the motivations for citizens to establish reuse social enterprises in Ireland. Secondly, the paper examines the factors that contribute to reuse social enterprises in Ireland becoming sustainable.

The research points to the necessity of reuse social …

Dynamic Electrical Ratings And The Economics Of Capacity Factor For Wave Energy Converter Arrays, Fergus Sharkey, Elva Bannon, Michael Conlon, Kevin Gaughan

Conference papers

Wave Energy Converters (WECs) have been in development for several decades with some devices now coming close to commercial realities. As such, pilot projects are being developed, particularly in the UK and Ireland, to deploy WECs on a pre-commercial array scale. The ultimate ambition is to have multiple WECs installed in a ‘wave farm’ in a similar fashion to offshore wind farms. For large scale wind farms the inter-array and export electrical systems can represent more than 20% of the project’s capital expenditure. Submarine power cables account for a large proportion of this cost. The same is expected to hold …

Analysis Of Mimo Communications Systems Based On Experimentally Observed Channels, Pat Chambers

Doctoral

This thesis presents an analysis of multiple-input/multiple-output (MIMO) communications systems where the objective is to provide a unified solution to the problems of (i) crosstalk coupling in transmission line channels (ii) multi-path fading in the time variant high frequency wireless channel. In the case of transmission line channels, a comparative analysis is presented of the performance of MIMO communications systems based on balanced CAT 5 twisted-pair transmission lines, balanced twisted-pair telephone transmission lines scheme as well as unbalanced flat-pair transmission lines. The unbalanced flat-pair transmission lines are viewed as a model for digital subscriber lines (DSLs) which may be deemed …

Adequacy Assessment Of The Irish Generation System Including Wind Capacity, William Carr

Masters

Adequacy assessment of generation capacity is a statistical measure of the ability of existing or planned generation plant to meet predicted levels of electrical demand. Complications arise in this calculation because at any point in time the exact level of capacity available is variable due to planned and forced outages. Planned outrages is a term used to describe the period during the year when a generation unit is required to be shut down for maintenance work to be carried out. The duration of this outrage is normally known and its timing can be chosen. Forced outages describe the random failure …
