The largest category of power plants applying to connect to the US grid are now solar, and over a third of those are hybrids that include battery storage.
It’s evidence of political solidarity and a strengthening of ties between Ukraine and the EU.
Typical amounts of solar particles hitting the Earth’s magnetosphere can be beautiful, but too much could be catastrophic.

Every few centuries the Sun blasts the Earth with a huge amount of high-energy particles. If it were to happen today, it would wreak havoc on technology.
The U.S. has thousands of lakes and reservoirs that could be paired for pumped hydro storage without the need for rivers.

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.
Integrating solar panels with farming can provide partial shade for plants.

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.
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.
Lead in pipes can contaminate the water supply, resulting in poisoning.

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.
Lagos only gets about 10 percent of its electricity needs, leaving its 20 million inhabitants to their own devices.

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.
By centrally controlling when household water heaters (geysers) can be switched on and off, South Africa can ease up electricity demand during peak consumption times.

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.
