A team of researchers found 35,000 pairs of existing reservoirs, lakes and old mines in the US that could be turned into long-term energy storage – and they don’t need dams on rivers.
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.
Almost one in three Australian homes now have solar panels – but as even more solar systems are installed, we face a growing challenge of managing temporary solar shutdowns.
The ins and out of South Africa’s national power grid and why Eskom keeps tripping the switch.
Developments in the energy sector shouldn’t be reduced to technological sophistication. They should be guided by how they improve the livelihoods of the intended beneficiaries.
Three experts explain a few aspects of American infrastructure that desperately need investment.
Nigeria’s attempt at privatising its power infrastructure hasn’t been without challenges but they are not insurmountable.
Australia has a lot of work to do to overcome the challenges facing electric vehicles users, starting with the lack of a comprehensive national charging network.
Nigeria’s unreliable power supply comes with a triple challenge of social, economic and environmental costs.
Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.
Centrally switching water heaters on and off at specific times can distribute the demand for electricity and lead to energy saving.
The Buhari government must do more to solve Nigeria’s intractable energy problems.
Due to inefficiencies in global energy systems, energy falls short of even making it to the consumer, often lost in the form of waste heat.
Long before Apple vs. Microsoft or Facebook vs. Google, there was Edison vs. Westinghouse.
Wild things thrive in transmission pathways that crisscross states.
We have all the technologies needed to make the electric grid run on renewables and lower pollution. What are they and what are the barriers to adopting them widely?
US and Russian tension over power grid cyber attacks is a concern for global stability, but it also highlights our own critical infrastructure vulnerabilities.
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.
Electric utilities have a right to make money on their government-granted monopolies, but customers also have a right to know what cyber-protections they would get if they paid more.
South Africa’s president has committed to structural reforms in the energy sector.
