Carbon tax: The next steps – practical implementation and mitigating actions

Carbon tax came into effect on 1 June 2019 as part of the government’s drive to reduce carbon emissions and comply with its promises and commitments on climate change. Phase 1 of the tax sees carbon emissions taxed at a rate of R120/t of CO2e (carbon dioxide equivalent), and with the various allowances considered, the […]

Impacts and health effects of air pollution by Eskom, Sasol Synfuels and Natref

. A new study report on the air quality and health effects of air pollution by Eskom, Sasol Synfuels and Natref in and around South Africa’s Highveld Priority Area (HPA) provides shocking evidence of the harmful effects caused by these organisations to the environment and to human health. The study report by Dr Gray is […]

Clean energy powers healthcare facilities

With the increasing pressure to lower carbon emissions, the use of coal-fired equipment is phasing out. As part of the Green Initiative, the South African government has been encouraging and supporting alternative fuel options. Natural gas is one of the best options, being both effective and environmentally friendly. CNG Holdings, through its Virtual Gas Network […]

The sorry state of air pollution from Eskom’s coal-fired power stations

. With all the emphasis currently focused on Eskom’s financial and operational sustainability and future structure, the utility’s environmental performance and sustainability is inevitably neglected, and indeed has become the sacrificial lamb on the altar of the money gods. In October 2018, an analysis and study of Eskom’s own air pollution monitoring reports, commissioned by […]

Carbon emissions set to rise in 2018 for first time in five years

According to the International Energy Agency (IEA) carbon emissions from advanced economies set to rise in 2018 for first time in five years, reversing a declining trend. The organisation reports that the world’s advanced economies will see an uptick in their carbon dioxide (CO2) emissions this year, bucking a five year-long decline.

How sales of new electric vehicles have hit record levels

Dynamic market uptake of electric vehicles (EVs) has occurred in recent years. On-going support and commitments for increased deployment of EVs from policy makers and the automotive industry has resulted in increased sales volumes. This, together with growing competition in the development of new technologies, are likely to contribute to continuous reductions in the cost […]

An assessment of new coal plants in South Africa’s electricity future

.  An important new research report by Gregory Ireland and Jesse Burton, of the Energy Research Centre (ERC), University of Cape Town, was published on 30 May 2018. The report assesses the cost, emissions and supply security implications of South Africa’s coal baseload independent power producer (IPP) procurement programme which was launched in 2014 in line with […]

More nuclear power in China

The World Nuclear Association released a report on China’s electricity generating plans recently. The report – of which this is an extract – states that most of mainland China’s electricity is produced from fossil fuels, predominantly from coal – 73% in 2015. Two large hydro projects are recent additions: Three Gorges of 18,2 GWe and Yellow […]

How modern gas turbines achieve excellent environmental performance at high load

This article explains how the gas turbines used at the Dedisa and Avon peaking power plants – which were highlighted in the June 2016 edition of Energize (“Privately owned peaking power station nears completion”) – achieve their environmental performance with lower NOx emissions even when operating at peak load. Dedisa and Avon peaking power stations […]
