If builders could incorporate solar harvesting into the siding of a building, the amount of energy from the grid that a structure would need may significantly decrease. Researchers have demonstrated the potential of wedge-shaped luminescent solar concentrators (LSCs). These efficient modular solar units could easily be hung on the side of a building.
For solar boom, scrap silicon for this promising mineral
3 Aug 2020 at 11:00am
Engineers have found that photovoltaic wafers in solar panels with all-perovskite structures outperform photovoltaic cells made from state-of-the-art crystalline silicon, as well as perovskite-silicon tandem cells, which are stacked pancake-style cells that absorb light better.
Harnessing wind data to help meet energy needs in Florida
30 Jul 2020 at 1:08pm
A new study shows how upcoming technological advances could make wind energy a hot commodity in the Sunshine State.
Offshore wind power now so cheap it could pay money back to consumers
27 Jul 2020 at 8:46am
The latest round of offshore wind farms to be built in the UK could reduce household energy bills by producing electricity very cheaply.
New technology makes homes more energy independent, helps divert power during...

Researchers have designed a smart technology that can help utility companies better serve communities affected by power outages. The researchers said their single device works by improving energy delivery between home solar-power systems and the electrical grid.
Scientists develop new material for longer-lasting fuel cells
22 Jul 2020 at 4:21pm
New research suggests that graphene -- made in a specific way -- could be used to make more durable hydrogen fuel cells for cars.
Geoengineering is just a partial solution to fight climate change
20 Jul 2020 at 6:32am
Could we create massive sulfuric acid clouds that limit global warming and help meet the 2015 Paris international climate goals, while reducing unintended impacts? Yes, in theory, according to a new study. Spraying sulfur dioxide into the upper atmosphere at different locations, to form sulfuric acid clouds that block some solar radiation, could be adjusted every year to keep global warming at levels set in the Paris goals. Such technology is known as geoengineering or climate intervention.
The secret to renewable solar fuels is an off-and-on again relationship
17 Jul 2020 at 7:10am
Copper that was once bound with oxygen is better at converting CO2 into renewable fuels than copper that was never bound to oxygen, according to scientists.
