A case study of climate variability effects on wind resources in South Africa

Autor: Lynette Herbst, Jorg Lalk

Publikováno v: Journal of Energy in Southern Africa, Vol 25, Iss 3, Pp 2-10 (2017)
Journal of Energy in Southern Africa, Volume: 25, Issue: 3, Pages: 02-10, Published: AUG 2014

The wind energy sector is one of the most prominent sectors of the renewable energy industry. However, its dependence on meteorological factors subjects it to climate change. Studies analysing the impact of climate change on wind resources usually on

Review of proposals for practical power sector restructuring and reforms in a dynamic electricity supply industry

Autor: Jorg Lalk, Muhammad Tahir Khan, George Alex Thopil

Publikováno v: Renewable and Sustainable Energy Reviews. 62:326-335

South Africa׳s electricity supply industry (ESI) remains a vertically-integrated monopoly despite global trends towards restructuring. The monopolistic nature of the ESI could hinder the development of distributed power systems as penetration of ren

Techno-economic performance comparison of crystalline and thin film PV panels under varying meteorological conditions: A high solar resource southern hemisphere case

Autor: George Alex Thopil, Jorg Lalk, Miriam Thopil, Christiaan Eddie Sachse

Publikováno v: Applied Energy. 275:115041

Photovoltaic panel technologies have evolved considerably over a limited period. The most popular PV panel technologies can be divided into two main groups, the first being crystalline technologies and second, thin film technologies. This investigati

AN INVESTIGATION INTO THE BARRIERS TO ENERGY EFFICIENCY WITHIN MEDIUM TO LARGE MANUFACTURING FIRMS OPERATING WITHININ THE ETHEKWINI MUNICIPAL AREA

Autor: Jorg Lalk, Resham Singh

Publikováno v: South African Journal of Industrial Engineering, Vol 27, Iss 3, Pp 287-302 (2016)
South African Journal of Industrial Engineering, Volume: 27, Issue: 3, Pages: 287-302, Published: NOV 2016

Preliminary investigations into the energy efficiency of manufacturing firms operating in South Africa have shown that no previous study of the barriers to energy efficiency has been conducted. This paper sets out to investigate whether there is an e

A review of the policy documents behind South Africa's Renewable Energy Independent Power Producer Procurement Programme: How its hits and misses impact society

Autor: Jorg Lalk, Lynette Herbst

Publikováno v: ISTAS

Apartheid in South Africa (SA) left a legacy of uneven access to electricity, impacting the quality of the lives of many. Furthermore, the country's economy has been stifled by loadshedding (scheduled power interruptions) since 2008. Two policy docum

Wind farms associated with flywheel energy storage plants

Autor: Jorg Lalk, Lynette Herbst, M. Chudy

Publikováno v: IEEE PES Innovative Smart Grid Technologies, Europe.

Recent developments in flywheel technology opens new possible applications. Connecting flywheels and wind generators is not a new idea. However, flywheels were always considered as a short time compensation of stochastic output variations of wind gen
