Zimbabwe’s policy makers believe that deforestation is a threat to the economy, but citizens believe environmental degradation is an outcome of the country’s dire political and economic situation.
South Africa can’t afford new nuclear infrastructure with state funds in these times of budget shortfalls and ballooning debt.

With its abundant sunshine and unique topography, Indonesia is able to generate 100% green electricity from its solar energy by 2050.
The first two of 24 new solar and wind farms under construction were completed in February but there’s still a long way to go to boost electricity supply.

When South Africa finally emerges from COVID-19 inadequate electricity supply will be once again rear its head.
Mining is one of the industries that’s helped by mathematical modelling: models can predict ceiling collapses and keep miners safe.

Taxes designed to encourage a green transition can instead penalise smaller businesses and ensure they’re left behind.
Changing incandescent light bulbs (right) to LEDs (left) is an example of eco-efficiency, but it can also have unintended consequences.

Often presented as one of the best ways to save energy, eco-efficiency often proves to be less effective than one might think.
Household actions lead to changes in collective behaviour and are an essential part of social movements.

Households generate a large share of national greenhouse gas emissions and can take steps to reduce them.
The next 20 years of Britain’s electricity policy must look very different from the previous 20.
Untapped energy sources: hydro-power potential is concentrated along the Zambezi River in Zimbabwe.

Zimbabwe’s energy policy needs to be reconsidered if the country’s electricity shortage is to be resolved.
Power cuts continued to plague some African countries.

There has been no progress in expanding national electricity grids in most African countries since 2016.
Few people would have predicted in 2010 that by the end of the decade, electricity generation from renewables would outpace nuclear.

Britain greets a new decade with substantially cleaner electricity, but challenges lie ahead to decarbonise its transport and heating.
In some countries, as much as half of the generated electricity is lost in transmission.

Due to inefficiencies in global energy systems, energy falls short of even making it to the consumer, often lost in the form of waste heat.
Projections are often be repeatedly wrong. That’s because the models don’t learn from mistakes.

From wage growth to renewable energy to religion, projections are being treated as predictions. We’d be better off insisting on genuine forecasts.
