The main difference between EVs and hybrid cars is how they are powered. An EV gets its power exclusively from electricity, while hybrid cars – as the name suggests – run on a mix.

The reality is that natural gas is an uncertain investment. Many different variables affect the price of gas on the international trading markets.

Unfortunately, compressed natural gas is not actually a green alternative fuel. CNG-powered vehicles are just as bad for the environment as their petrol or diesel counterparts.

A white person's right hand is touching the meter at the point where the numbers are going up, perhaps to convey the idea that the person is worried about their gas consumption. There is a thick layer of dust on the meter.

The place of natural gas in a clean energy future is hotly debated. But, there is a simple answer to whether natural gas is renewable.

Soil erosion is a serious environmental problem in South Africa, affecting both land and water resources.

The link between coal, gas and water pollution is clear, but the extraction and use of fossil fuels affect ecosystems in many less obvious ways as well.

To boost the uptake of electric vehicles in South Africa, we need measures to make going electric a more attractive option for motorists.

Running an electric car saves money long term, and it also means being less vulnerable to temporary price spikes and shortages of petrol and diesel.

South Africa is experiencing a number of environmental issues, including global warming, pollution and species loss.

Renewable energy funds are a vital tool for South Africa’s green energy transition. They can pay for everything from infrastructure upgrades to mine rehabilitation.

“There are no jobs on a dead planet!” goes the old slogan. Environmental degradation is a serious risk to economic growth.
