Hydrogen is a fuel source that is a possible alternative to fossil fuels. It can be used in fuel cells and to create heat, and its only by-product is water, meaning it does not release any greenhouse gases when burned.

A carbon footprint is the number of greenhouse gases emitted through a person, business or even a country’s activities. These greenhouse gases include carbon dioxide and methane.

Greenhouse gases are gases that trap heat in the atmosphere. This can be any gas that absorbs infrared radiation and contributes to the Earth’s warming or the greenhouse effect.

Load shedding happens when selected sections of South Africa’s electricity grid are shut down. In literal terms, Eskom, the country’s power utility, “sheds” a certain “load” – or amount – of electricity from the national grid.

Explainer The Many Uses of Compressed Natural Gas (CNG)

Compressed natural gas (CNG) is natural gas that has been compressed to less than one per cent of its volume. The gas is compressed when it is stored at very high pressures.

Biogas is a renewable energy source produced when anaerobic bacteria break down organic materials. It is different from natural gas as natural gas is a fossil fuel, while biogas is a renewable energy source.
