A mix of wind, solar photovoltaics, and some natural gas would be more cost-effective than Inga 3 for South Africa and the DRC.
Some coal workers have the right skills and work in the right location to get a job in renewables. But many, such as semi-skilled machine operators, cannot.
Increased business lobbying for incentives and mandates may tip the balance in favor of a cleaner US energy policy.
Renewables technology already exists, it's getting cheaper and we will never go to war over sunshine. If you need to be convinced of the potential of wind and solar, read this.
How indoor solar cells could help power the Internet of Things.
Environmentalists say the new film has caused untold damage at a time when change has never been more urgent. So why is it so controversial?
A new nuclear plant called Barakah is nearing completion in the UAE. But it risks further stabilising the volatile Gulf region.
Sun Cable could provide Australia an alternative to the export business of coal and gas, and even reduce our export dependence on China.
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.
Drought-driven humanitarian emergencies can be prevented if groundwater is reliably made available at strategic locations.
Unpacking what South Africa's new energy plan says about nuclear energy.
Australia's renewables revolution proves that there's cause for hope in our emissions reduction goals. But we cannot rest on our laurels.
Tapping just 3.7% of solar potential in countries in China's intercontinental infrastructure programme could power the entire region.
Scientists spend years preparing for the two-minute window of a total solar eclipse.
Solar and wind can't deliver power on demand. But overbuilding solar and wind, and simply dumping unneeded energy, would go a long way to smoothing out those bumps, study finds.
The Trump administration's Affordable Clean Energy Plan would help the declining coal industry, but a study shows many coal workers could transition to a new industry – solar – and earn more money.
Blockchains and AI could play a key role in the decentralised energy systems of the future.
Large-scale solar and wind tend to push energy prices down, which sounds great as a consumer. But that makes keeping the grid in constant balance harder.
Solar photovoltaics and wind power are on track to supplant fossil-fuel-based electricity generation by the 2030s. The only thing holding back the renewable revolution is politics.
South Africa's power utility would do well to consider swapping out expensive new coal-powered capability for renewables.
