Good news for rooftop solar, not for home batteries

The energy produced over the lifetime of typical rooftop solar panels more than makes up for the energy it takes to make, mount and then eventually recycle them. But adding a home battery usually lowers those dividends, according ...

'Sun in a box' would store renewable energy for the grid

MIT engineers have come up with a conceptual design for a system to store renewable energy, such as solar and wind power, and deliver that energy back into an electric grid on demand. The system may be designed to power a ...

Does energy storage make the electric grid cleaner?

Carbon-free energy: Is the answer blowing in the wind? Perhaps, but the wind doesn't always blow, nor does the sun always shine. The energy generated by wind and solar power is intermittent, meaning that the generated electricity ...

'Smart' transformers could make reliable smart grid a reality

A new study using complex computational models finds that smart solid-state transformers (SSTs) could be used to make a stable, reliable "smart grid" - allowing the power distribution system to route renewable energy from ...
