Buildings as power stations work: They generate more energy than they consume, data shows

The UK's first energy-positive classroom generated more than one and a half times the energy it consumed, according to data from its first year of operation, the team has revealed. The findings were announced as the researchers launched the next phase of their research, gathering data and evidence on an office building, constructed using similar methods. … read more

New material for splitting water

Solar energy is clean and abundant, but when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis. In photocatalytic water splitting, sunlight separates water into hydrogen and oxygen, which can then be recombined in a fuel cell to release energy. Now, a new class of materials -- halide double perovskites -- may have just the right properties to split water. … read more

Early Impact of Solar Tariffs Being Felt Nationwide

The solar industry has now had a handful of months to digest the solar panel tariffs that were implemented by the Trump Administration in January, and the early verdict is somewhat of a mixed bag. Domestic solar capacity has ratcheted up in the front half of 2018 thanks to investments by solar companies seeking to […]

AI software assists design of new material for solar cells

Researchers have used machine learning to design new polymers for organic photovoltaics (solar cells). After mining data from previous studies, they input the physical properties of polymers, together with the resulting solar cell efficiencies, into a Random Forest model to statistically predict the effectiveness of new materials. This informatics-based screening, combined with traditional knowledge-guided design, could vastly accelerate solar cell development compared with current trial-and-error experimentation. … read more

How greener grids can stay lit

Without careful management, distributed energy resources have the potential to cause unreliable power delivery, or even outages, and lead utility companies to overcharge customers. A new index will help ISOs and utilities account for uncertainties introduced by both the electricity market and DERs so utility companies can balance the distribution grid and find the fairest customer rates. … read more
