Agriculture is both a victim and culprit of climate change. The sector is a major source of greenhouse gas emissions and is acutely vulnerable to the effects of climate change.
The main greenhouse gas is carbon dioxide (CO2), produced by burning fossil fuels. South Africa is the biggest emitter of greenhouse gases on the African continent.
Nitrous oxide (N2O) is a greenhouse gas (GHG), more commonly known as laughing gas. While N2O rarely makes headlines, it is a dangerous driver of climate change.
South Africa is no stranger to companies wanting to use offshore drilling to search its coastal waters for oil and gas deposits.
Transportation has a significant impact on climate change, and biofuel could be one of the solutions.
Experts say that hydrogen is one answer to South Africa’s greenhouse gas emissions problem.
South Africa’s Low Emission Development Strategy 2050 is the country’s most recent emissions reductions plan.
South Africa’s Integrated Resource Plan (IRP) is the country’s long-term energy plan until 2030. It became official government policy in October 2019.
A fuel cell uses chemical energy from fuels, like hydrogen, propane or diesel, to produce electricity. Fuel cells can use a wide range of fuels and have a wide range of applications.
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.
Liquefied petroleum gas (LPG) is the gaseous form of two kinds of natural gases: butane and propane. It can also be a mix of the two gases. Butane and propane are similar but have different properties, making them suitable for different things.
A wind turbine works by harnessing the power of the wind to create wind energy. The wind turns large blades around a rotor. This, in turn, powers a generator, which creates electricity.
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.
A carbon tax is a fee paid to the government by carbon dioxide (or carbon dioxide equivalent) emitters for every tonne of carbon emitted.
South Africa is a coal-dependent country. Coal makes up 74 per cent of the country’s total electricity supply. In the first quarter of 2021, 81.8 per cent of South Africa’s electricity came from coal.
Carbon dioxide is a chemical compound that presents as a gas in the Earth’s atmosphere. It consists of one carbon atom and two oxygen atoms.
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.
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.
Since 2006, the amount of gas in the atmosphere has increased, according to NASA. The oil and gas industry has caused the majority of methane gas emissions since 2006, NASA says.
