40 h. ago Ocean currents can generate electricity, and our study shows Africa's seas have some of the strongest

The world's oceans cover more than 70% of Earth's surface. They're filled with currents, some much stronger than the fastest flowing large rivers. These currents can be harnessed as clean, marine renewable energy. Marine energy is much more predictable and reliable than many other forms of renewable energy because unlike the sun and wind, which regularly do not produce electricity, ocean currents never stop moving around the planet. New research has found that the eastern and south-eastern coasts of Africa have currents that put them among the world's top potential locations for ocean energy production. Researchers Mahsan Sadoughipour, James VanZwieten, Yufei Tang and Gabriel Alsenas explain what is needed to bring renewable marine energy into African countries' electricity mix.

First Nations across British Columbia have developed renewable electricity projects for decades. Yet they've experienced significant barriers to implementing, owning and managing their own electricity supply. That's because there have been few procurement policies in place that require their involvement.

4 d. ago Green hydrogen from Africa much more costly than previously assumed

To meet Europe's demand for green hydrogen, governments and the private sector have high hopes for production in Africa. A study led by the Technical University of Munich (TUM) and published in Nature Energy has now shown that the financing costs for production facilities in African countries would be much higher than previously assumed.

Alex de Vries-Gao, a PhD candidate at VU Amsterdam Institute for Environmental Studies, has published an opinion piece about the results of a simple study he conducted involving the possible amount of electricity used by AI companies to generate answers to user queries. In his paper published in the journal Joule, he describes how he calculated past and current global electricity usage by AI data centers and how he made estimates regarding the future.

As winter approaches, memories of the past haunt South Africans in more ways than one. The country has experienced years of rolling blackouts, known locally as load shedding. During the worst periods of these power cuts in 2022 and 2023, South Africans who did not own solar photovoltaic systems or generators would go without electricity for up to 12 hours a day.
