Scientists from Trinity College Dublin have taken a giant stride towards solving a riddle that would provide the world with entirely renewable, clean energy from which water would be the only waste product. Reducing humanity’s carbon dioxide (CO2) emissions is arguably the greatest challenge facing 21st-century civilization – especially given […]

Using drought-prone California as a case study, a research team shows that increased solar and wind energy can reduce the reliance on hydropower, especially during drought.

Tiny, self-propelled robots could someday be used to clean up radioactive waste. Credit: American Chemical Society According to some experts, nuclear power holds great promise for meeting the world’s growing energy demands without generating greenhouse gases. But scientists need to find a way to remove radioactive isotopes, both from wastewater […]

Nuclear power plants contain miles of pipes of different sizes. Shown is the turbine floor with new reheaters and secondary side piping at Unit 2, Watts Bar Nuclear Power Plant, 2012. Credit: Tennessee Valley Authority A failing pipe can be tough to spot. It may cause a puddle, produce another […]

Switching from coal to natural gas and renewables for electricity generation could save at least 12,000 billion gallons water a year by 2030, a Duke University study finds.
