Newer Solar Power Equipment Ages Better Than Older Units

July 7, 2020 sarah Jonas Electricity, Energy, Photovoltaic, Renewable Energy, Solar energy, Solar Power

Utility-scale photovoltaics are the largest sector of the overall solar market within the U.S. and the fastest-growing form of renewable power generation, and this fleet of utility-scale photovoltaic projects is relatively young and hasn’t been operating long enough to establish a lengthy history of operational field service. In the Journal of Renewable and Sustainable Energy, researchers assess the performance of 411 utility-scale photovoltaic projects built within the U.S. from 2007 through 2016.

Cooling Mechanism Increases Solar Energy Harvesting for Self-Powered Outdoor Sensors

July 7, 2020 sarah Jonas Applied Physics Letters, Energy, Power Generation, radiative cooling, Renewable Energy, solar energy harvesting

Thermoelectric devices, which use the temperature difference between the top and bottom of the device to generate power, offer some promise for harnessing naturally occurring energy. In Applied Physics Letters, authors tested a device made up of a wavelength-selective emitter that constantly cools the device during the day using radiative cooling. As a result, the top of the device is cooler than the bottom, causing a temperature difference that creates constant voltage through day and night and various weather conditions.

Finding Balance Between Green Energy Storage, Harvesting

June 2, 2020 sarah Jonas Climate Change, Energy Storage, Renewable Energy, Solar energy, Wind Energy

Generating power through wind or solar energy is dependent on the abundance of the right weather conditions, making finding the optimal strategy for storage crucial to the future of sustainable energy usage. Research published in the Journal of Renewable and Sustainable Energy identifies key indicators that will help achieve balance between green energy storage capacity and harvesting capability and determine the energy potential of a region.

RENEWABLE ENERGY ADVANCE

May 26, 2020 sarah Jonas Machine Learning, Materials Science, Renewable Energy, renewable energy storage

In order to identify materials that can improve storage technologies for fuel cells and batteries, you need to be able to visualize the actual three-dimensional structure of a particular material up close and in context. Researchers from the University of Delaware’s Catalysis Center for Energy Innovation (CCEI) have done just that, developing new techniques for characterizing complex materials.

Solar Power Plants Get Help from Satellites to Predict Cloud Cover

April 14, 2020 sarah Jonas Energy, Journal of Renewable and Sustainable Energy, NASA, Physics, Renewable Energy, Satellite, Solar Power, sunlight, University Of California San Diego, weather forecasting

Cloud cover is often characterized in simple terms, such as cloudy, partly cloudy or clear. This does not provide accurate information for estimating the amount of sunlight available for solar power plants. In this week’s Journal of Renewable and Sustainable Energy, a new method is reported for estimating cloud optical properties using data from recently launched satellites. This new technique is known as Spectral Cloud Optical Property Estimation, or SCOPE.
