How insulation and heat pumps could cut the UK’s – and other countries’ – need for Russian gas [Update]

electric heat pumps

As the global energy crunch deepens, thanks to Russia’s invasion of Ukraine, new analysis from the nonprofit think tank Energy & Climate Intelligence Unit (ECIU) looks at how home insulation and heat pumps could reduce the UK’s need for Russian gas. The approach could certainly be applied in other countries, too.

Will this metal recycling startup revolutionize the battery and clean energy sectors? [Update]

US minerals

Most of the materials required for batteries and other clean energy technology are dirty to mine. They’re also mostly controlled by China. Can a recycling technology startup change that?

Electrek spoke with Megan O’Connor, cofounder and CEO of Nth Cycle, a Beverly, Massachusetts-based developer of a recycling technology that extracts critical metals from batteries for a second life, about how to enable a clean, domestic, and streamlined supply of critical minerals for the clean energy transition. Nth Cycle’s technology was developed at Harvard and Yale universities.

In April, Nth Cycle received $3.2 million in seed funding led by Boston-based clean energy venture capital company Clean Energy Ventures.

Here’s how rooftop solar could have prevented 2021’s Texas big freeze power outage

Biden solar tariffs

A year on from the big Texas freeze that knocked out the state’s power system and caused at least 246 deaths, new research released yesterday found that rooftop solar could have supplied more than enough electricity to meet the shortfall on all but two of the 13 days when power production fell short of forecasted demand.
