Climate change is an issue that requires global attention and co-operation. As climate science develops an understanding of changes to the future climate state, policy makers and engineering project planners beg to know what claims can be made on the subject with a reasonable level of...

Producing electricity from wind is attractive because it provides a clean, low-maintenance power supply. However, wind resource is intermittent on various time scales, thus introducing variability in power output that is difficult for electric grid planning. In the following study, wind resource...

South Africa hopes to expand wind and solar power. Success depends on how and where to deploy the technologies. This study develops a 10-year database of expected power generation for these technologies across South Africa. A power system model simulates the performance of different spatial...

A decarbonized global energy sector is expected to need cumulative investments in the tens to hundreds of trillions of dollars between now and 2050. Due to its size, the current climate-business environment is therefore prone to corruption risks. Yet such corruption risks are rarely explored...

In order to overcome the electricity demand in the country and in its effort to reduce the greenhouse gas emission and climate change, South African (SA) government is encouraging research in the field of renewable energy (RE). Higher educational institutions in each province are involve in...

One of the main reasons attributed to the slow uptake of grid-connected residential PV (photovoltaic) systems, is the lack of information about the near-term economic benefits which are as important as long-term viability for residential customers. This paper presents a comparative assessment of...

The widespread use of the renewable energies requires compulsorily the development of new technological solutions for the efficient employment of these resources, such as small size, cogenerative power plants.
