Storing energy can make renewables more reliable, but current technologies such as lithium-ion batteries are limited by safety issues, high costs and other factors

Heating simple metal oxides, like rust, could become the foundation for a solar technology that would make and store electricity by separating the hydrogen and oxygen atoms that make up water.

Findings speak to a growing sustainability movement to capture energy from existing waste

Researchers' findings demonstrate that renewable pollens could produce carbon architectures for anode applications in energy storage devices

Algae are an ideal source of biomass, but researchers have not yet found a cost-competitive way to use algae for fuels

Mechanical trees become power ‘plants’ when they sway in breeze

Research shows a transition to a reliable, low-carbon, electrical generation and transmission system can be accomplished with commercially available technology and within 15 years

New procedure could eventually replace the need for petroleum-based fuel sources

Researchers use a combination of cheap materials to make a highly energy efficient catalyst for electrochemically reducing CO2 into syngas

Research looks at large community issues from the single-unit level
