How California’s ambitious new climate plan could help speed…
California is embarking on an audacious new climate plan that aims to eliminate the state’s greenhouse gas footprint by 2045, and in the process, slash emissions far beyond its borders. The blueprint calls for massive transformations in industry, energy and transportation, as well as changes in institutions and human behaviors.

Study: Enough rare earth minerals to fuel green energy…
The world has enough rare earth minerals and other critical raw materials to switch from fossil fuels to renewable energy to produce electricity and limit global warming, according to a new study that counters concerns about the supply of such minerals.

Rethinking a waste product of the timber processing industry
An interdisciplinary team of researchers from the Max Planck Institute of Colloids and Interfaces (MPICI) has investigated how the natural properties of native tree bark can be used to create a standardized product for long-term use without the addition of adhesives. In doing so, they have created bark panels by peeling and drying via hot pressing, which could be used in interior design or furniture and packaging, for example, through industrial production.

Stability of perovskite solar cells reaches next milestone
Perovskite semiconductors promise highly efficient and low-cost solar cells. However, the semi-organic material is very sensitive to temperature differences, which can quickly lead to fatigue damage in normal outdoor use. Adding a dipolar polymer compound to the precursor perovskite solution helps to counteract this.

Harvesting big energy from small movement
Since the ancient Greeks, humankind has known that if you bring two things into contact, a small amount of electricity is created. One example is that we can rub a balloon with our hair and generate enough electricity to stick it to the ceiling.

Coating provides radiation barrier for perovskites in space, protection…
An ultrathin protective coating proves sufficient to protect a perovskite solar cell from the harmful effects of space and harden it against environmental factors on Earth, according to newly published research from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).

New electrode design for lithium-ion batteries that improves performance
Korea Institute of Machinery & Materials (KIMM) has announced the development of the design and process technology for the world’s first battery electrode that significantly improves the performance and stability of batteries used in electronic devices such as smartphones, laptops, and electric vehicles.

Temperature-sensing building material changes color to save energy
Researchers at the University of Chicago’s Pritzker School of Molecular Engineering (PME) have designed a chameleon-like building material that changes its infrared color—and how much heat it absorbs or emits—based on the outside temperature. On hot days, the material can emit up to 92 percent of the infrared heat it contains, helping cool the inside of a building. On colder days, however, the material emits just 7 percent of its infrared, helping keep a building warm.
