Power stations driven by light

Green plants, algae and some bacteria use sunlight to convert energy. The pigments in chlorophyll absorb electromagnetic radiation, which induces chemical reactions in electrons. These reactions take place in the nucleus ...

Fixing the environment: when solutions become problems

In a world where climate change, air and water pollution, biodiversity loss, water scarcity, ozone depletion, and other environmental problems overlap, a fix in one arena can cause trouble in another.

Aluminum nitride to extend life of solar power plants

NUST MISIS scientists together with their colleagues from the Central Metallurgical R&D Institute (Cairo, Egypt) have developed a composite material to extend the life of solar towers up to five years. The research article ...

Chernobyl begins new life as solar power park

Ukraine launched Friday a park of photovoltaic panels at the former Chernobyl power plant as the country seeks to use solar power to give the scene of the world's worst nuclear disaster a new lease on life.

Solar seeks its place under Spanish sun
