Self-charging battery both generates and stores energy

(Phys.org) -- Renewable energy technologies generally consist of two distinct processes: energy generation (using sources such as coal, solar, wind, etc.) and energy storage (such as batteries). These two processes are always ...

Japan 'plans solar panels for all new buildings'

Japan is considering a plan that would make it compulsory for all new buildings and houses to come fitted with solar panels by 2030, a business daily said Sunday.

Dream of energy-collecting windows is one step closer to reality

Researchers at the University of Minnesota and University of Milano-Bicocca are bringing the dream of windows that can efficiently collect solar energy one step closer to reality thanks to high tech silicon nanoparticles.

First-ever global life cycle assessment of renewable energy future

A future where electricity comes mostly from low-carbon sources is not only feasible in terms of material demand, but will significantly reduce air pollution, a study published in the today's Proceedings of the National Academy ...

New applications for ultracapacitors

Devices called ultracapacitors have recently become attractive forms of energy storage: They recharge in seconds, have very long lifespans, work with close to 100 percent efficiency, and are much lighter and less volatile ...

US ranks 17 as clean tech producer, China is No. 2

Denmark earns the biggest share of its national revenue from producing windmills and other clean technologies, the United States is rapidly expanding its clean-tech sector, but no country can match China's pace of growth, ...

Renewable energy – not always sustainable

In a new thesis from Uppsala University, Simon Davidsson shows that a rapid expansion of renewable energy technology is not necessarily sustainable. To find the best way forward in the coming transition towards renewable ...
