Evaluation Of Wind And Solar Energy Investments In Texas, Byungik Chang, Ken Starcher

Civil Engineering Faculty Publications

The primary objective of the project is to evaluate the benefits of wind and solar energy and determine economical investment sites for wind and solar energy in Texas with economic parameters including payback periods. A 50 kW wind turbine system and a 42 kW PV system were used to collect field data. Data analysis enabled yearly energy production and payback period of the two systems.

The average payback period of a solar PV system was found to be within a range of 2-20 years because the large range of the payback period for PV systems were heavily influenced by incentives. …

The Heat Is On: The Capacities Required For The Establishment And Sustainability Of Community-Owned Renewable Energy District Heating Systems In Ireland, Gerard Doyle

Reports

International reviews of countries’ progress at tackling climate change show that Ireland is making small levels of progress on tackling issues associated with climate change. This paper will examine a theoretical framework, referred to as capacity analysis, to explain the capacities that need to be in place for the successful implementation of community-owned renewable energy district heating initiatives. The theoretical framework employed here is based on the ‘conceptual framework’ developed by Pringle which consists of four categories of capacity. The research methodology involves a case study with cases from Austria, Northern Ireland, the Republic of Ireland, Wales and Scotland. The …
