The transformation of the national electricity market has “progressed at a remarkable pace and scale” over the last year as it moves towards renewables, but security remains a critical issue.
The world runs on energy, so finding low-emission alternatives to fossil fuels is crucial. Wind and solar are cheap and abundant but can’t do everything. But hydrogen fuel could complete the picture.

The mainstream news media has been biased in its reporting and portrayal of Indigenous Peoples on stories about renewable energy projects. What and how can they do better?
Most proposed solutions don’t address the systemic problems facing Eskom, in particular its parlous finances.

The deluge of opinions and proposed solutions to South Africa’s energy crisis reflects corporate and political interests.
The Garzweiler surface mine produced 35 million tonnes of brown coal (lignite) in 2017. Germany plans to phase-out coal-fired power by 2038.

Plans to reduce emissions quickly are seductive but can stall. Climate initiatives should end dependence on fossil energy and pursue a path towards a more just and equitable society.
Australian-designed technology will soon be responsible for 50% of all solar energy produced globally.

A technological arms race in the 80s resulted in a world-first solar cell, that today underpins half the world’s solar power.
Lithium-ion batteries are already supporting renewable power generation, but a future without fossil fuels will need even better battery technology.

Investing billions in refurbishing nuclear generating stations doesn’t make economic sense as the cost of renewables fall dramatically.
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.
New research shows Ontario doesn’t really need nuclear energy, and its absence would not have an impact on emissions in the province’s energy sector.

Nuclear power isn’t needed to meet Ontario’s electricity needs. And the absence of nuclear power won’t have any impact on emissions in Ontario’s energy sector.
Hydroelectric power has helped Costa Rica ditch fossil fuels.
