International experience suggests South Africa can benefit by focusing on a simple restructuring of its power utility, allowing well-run state-owned entities to flourish.
Ghana’s power sector is mired in debt and excess production.
Sometimes wind and solar power produce more electricity than the local grid can handle. Better energy storage and transmission could move extra energy to where it’s needed instead of shutting it off.
COVID-19 variants are the products of the evolution of the SARS-CoV-2 virus. They arise via mutations, but other forces also have roles to play in the generation and transmission of variants.
As we move through the ongoing COVID-19 pandemic, new predictive methods of testing can help monitor the spread of the disease. Environmental testing, like swabbing floors, is a useful tool.
Renewable energy is expanding at a record pace, but still not fast enough. Here are the key areas to watch for progress in bringing more wind and solar into the power grid in 2022.
Manufacturing is just one part of the vaccine ecosystem. It’s the health system that delivers vaccines and people must be willing to take them.
A vaccinated person is less likely to get COVID, is less contagious, and is contagious for a shorter time.
Hurricane Ida left the entire city of New Orleans in the dark and renewed discussion of burying power lines. But there’s no way to completely protect the grid, above ground or below.
After the CDC changed course in late July, recommending universal masking indoors, Nevada became the first state to adopt a flexible masking policy that can quickly adjust to changing COVID-19 rates.
Parents face tough choices since young kids can’t yet get COVID-19 vaccinations. An infectious diseases expert offers guidance on navigating summer activities.
The COVID-19 vaccines are a smash success. But that doesn’t mean they keep every vaccinated person completely free of the coronavirus.
Vaccination is likely to substantially reduce virus transmission by reducing the pool of people who become infected, and reducing virus levels in people who do get infected.
In-person learning can safely resume as long as schools take steps to mitigate the spread of COVID-19.
You’ve been vaccinated; can you now safely see your friends and family? New research hints that vaccinated people may be less likely to transmit the coronavirus, but they are not 100% in the clear.
The Oxford/AstraZeneca vaccine is the second COVID shot to be approved in Australia, and it’s likely Australians will start receiving it next month.
Heat waves, droughts and deep freezes can all strain the electric grid, leading utilities to impose rolling blackouts. Climate change is likely to make these events more common.
A variant with a higher transmission rate is much more dangerous than one with just a higher fatality rate.
COVID-19 has been found in pets, zoo animals and in a wild mink in Utah. Monitoring wildlife for COVID-19 is important for animals and humans, both of whom face risks from a jumping virus.
Researchers say around 70% of the US needs to get the coronavirus vaccine to stop the pandemic. But questions around the vaccines and regional differences add some uncertainty to that estimate.
