Upper-ocean warming is changing the global wave climate, making waves stronger
14 Jan 2019 at 5:28am
Sea level rise puts coastal areas at the forefront of the impacts of climate change, but new research shows they face other climate-related threats as well. Scientists found that the energy of ocean waves has been growing globally, and they found a direct association between ocean warming and the increase in wave energy.
Integrated pathways for meeting climate targets and ensuring access to safe w...
11 Jan 2019 at 6:51am
Researchers have led work to develop new pathways showing how the world can develop water and energy infrastructure consistent with both the Paris Agreement and the UN Sustainable Development Goal 6 (SDG6) -- ensure availability and sustainable management of water and sanitation for all.
A new way to measure solar panel degradation
10 Jan 2019 at 11:17am
How does one inspect solar panels in real time, in a way that is both cost-effective and time-efficient? Researchers have now developed and improved statistical and machine learning-based alternatives to enable real-time inspection of solar panels. Their research found a new application for clustering-based computation, which uses past meteorological data to compute performance ratios and degradation rates.
Racial inequality in the deployment of rooftop solar energy in the United Sta...

Fewer rooftop solar photovoltaics installations exist in African-American and Hispanic-dominant neighborhoods than in white-dominant neighborhoods, even when controlling for household income and home ownership, according to a new study.
New materials could help improve the performance of perovskite solar cells
10 Jan 2019 at 11:16am
New research could lead to the design of new materials to help improve the performance of perovskite solar cells (PSCs).
Great potential for floating solar photovoltaics systems
8 Jan 2019 at 9:54am
Researchers estimate that installing floating solar photovoltaics on the more than 24,000 human-made US reservoirs could generate about 10 percent of the nation's annual electricity production. Their findings reveal for the first time the potential for floating PV to produce electricity in the United States.
Seawater turns into freshwater through solar energy: A new low-cost technology
7 Jan 2019 at 10:12am
Engineers have developed an innovative, low-cost technology to turn seawater into drinking water, thanks to the use of solar energy alone.
Droughts boost emissions as hydropower dries up
21 Dec 2018 at 9:36am
Recent droughts caused increases in emissions of carbon dioxide and harmful air pollutants from power generation in several western states as fossil fuels came online to replace hampered hydroelectric power. A new study quantifies the impact.
Powder could help cut CO2 emissions
19 Dec 2018 at 4:59am
Scientists have created a powder that can capture CO2 from factories and power plants. The powder can filter and remove CO2 at facilities powered by fossil fuels before it is released into the atmosphere and is twice as efficient as conventional methods.
Greener days ahead for carbon fuels?
18 Dec 2018 at 11:42am
A discovery shows that recycling carbon dioxide into valuable chemicals and fuels can be economical and efficient -- all through a single copper catalyst.
Upwind wind plants can reduce flow to downwind neighbors
18 Dec 2018 at 8:51am
New research highlights a previously unexplored consequence of the global proliferation of wind energy facilities: a wake effect from upwind facilities that can reduce the energy production of their downwind neighbors.
Flexible thermoelectric generator module: A silver bullet to fix waste energy...
18 Dec 2018 at 7:04am
Researchers developed an inexpensive large-scale flexible thermoelectric generator (FlexTEG) module with high mechanical reliability for highly efficient power generation. Through a change in direction of the top electrodes at the two sides of the module and the use of high density packaging of semiconductor chips, the FlexTEG module has more flexibility in any uniaxial direction.
Professor models system using baking soda filled capsules to capture CO2 emis...

Coal and natural gas represent the majority of the US energy supply. Even with pollution controls, burning these fossil fuels for energy releases a tremendous amount of carbon dioxide into the atmosphere. Research uses microcapsule technology that may make post-combustion carbon capture cheaper, safer, and more efficient.
Low-cost catalyst boosts hydrogen production from water
12 Dec 2018 at 9:18am
A future powered by carbon-free fuel depends on our ability to harness and store energy from renewable but intermittent sources, such as solar and wind. Now, a new catalyst gives a boost to a number of clean energy technologies that depend on producing hydrogen from water.
How will the winds of climate change affect migratory birds?
10 Dec 2018 at 12:18pm
Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring. Researchers came to this conclusion using data from 143 weather radar stations to estimate the altitude, density, and direction birds took during spring and autumn migrations over several years.
