Africa’s electricity capacity is expected to double by 2030 — and with the rapidly dropping cost of renewable energy technologies, the continent might seem poised to go green. But a new analysis suggests that fossil fuels will still dominate Africa’s energy mix over the next decade. The scientists used a machine learning approach that analyzes […]

An anode-free zinc battery that could someday store renewable energy

Renewable energy sources, such as wind and solar power, could help decrease the world’s reliance on fossil fuels. But first, power companies need a safe, cost-effective way to store the energy for later use. Massive lithium-ion batteries can do the job, but they suffer from safety issues and limited lithium availability. Now, researchers reporting in […]

What is renewable energy? | Live Science

Renewable energy comes from sources that are replenished naturally, such as the sun and wind. Traditional energy sources, like coal and oil, are finite and when burned, release carbon in the form of carbon dioxide and methane — two greenhouse gases that significantly contribute to the acceleration of global climate change. Renewable energy, on the […]
