Biodiversity and wind energy
The location and operation of wind energy plants are often in direct conflict with the legal protection of endangered species. The almost unanimous opinion of experts from local and central government authorities, environmental NGOs and expert offices is that the current mechanisms for the protection of bats in wind power projects are insufficient.

NREL investigates coatings needed for concentrating solar power
Next-generation concentrating solar power (CSP) plants require high-temperature fluids, like molten salts, in the range of 550-750 degrees Celsius to store heat and generate electricity. At those high temperatures, however, the molten salts eat away at common alloys used in the heat exchangers, piping, and storage vessels of CSP systems. New research at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) is aimed at mitigating corrosion levels in CSP plants with nickel-based coatings. (2017-09-18)
