US power sector carbon emissions intensity drops to lowest on record
4 Apr 2018 at 8:45am
Researchers have announced the release of the 2018 Carnegie Mellon Power Sector Carbon Index. The Index tracks the environmental performance of US power producers and compares current emissions to more than two decades of historical data collected nationwide. This release marks the one-year anniversary of the Index, developed as a new metric to track power sector carbon emissions performance trends.
Once we can capture CO2 emissions, here's what we could do with it
29 Mar 2018 at 10:31am
The carbon dioxide (CO2) emitted from power plants each year doesn't have to go into the atmosphere. Researchers are optimistic that within the next decade we will be able to affordably capture CO2 waste and convert it into useful molecules for feedstock, biofuels, pharmaceuticals, or renewable fuels.
Global carbon emissions could be cut 3 percent by following the UK's example
26 Mar 2018 at 11:02am
The UK cut its emissions from electricity production by 25 percent in 2016, using a strategy many countries could adopt to quickly lower carbon emissions.
20-year-old assumptions in solar cell production refuted
23 Mar 2018 at 7:48am
Researchers have investigated the manufacturing process of solar cells. The researchers proved that assumptions on chemical processes that were commonplace among researchers and producers for the past 20 years are, in fact, inaccurate.
Wood pellets: Renewable, but not carbon neutral
22 Mar 2018 at 11:09am
A return to firewood is bad for forests and the climate.
Potassium gives perovskite-based solar cells an efficiency boost
21 Mar 2018 at 11:10am
A simple potassium solution could boost the efficiency of next-generation solar cells, by enabling them to convert more sunlight into electricity.
Obtaining energy from marine currents
20 Mar 2018 at 7:24am
Researchers have developed procedures and designs to obtain energy from marine currents in areas of great depths optimizing the costs.
Detection, deterrent system will help eagles, wind turbines coexist better
19 Mar 2018 at 11:45am
Researchers have taken a key step toward helping wildlife coexist more safely with wind power generation by demonstrating the success of an impact detection system that uses vibration sensors mounted to turbine blades.
Manure could heat your home
8 Mar 2018 at 5:55am
Farm manure could be a viable source of renewable energy to help reduce greenhouse gas emissions that cause global warming.
With a TENG, solar cells could work come rain or shine
7 Mar 2018 at 8:27am
Despite the numerous advances in solar cells, one thing remains constant: cloudy, rainy conditions put a damper on the amount of electricity created. Now researchers have developed hybrid solar cells that can generate power from raindrops.
Running on renewables: How sure can we be about the future?
6 Mar 2018 at 8:57am
A variety of models predict the role renewables will play in 2050, but some may be over-optimistic, and should be used with caution, say researchers.
Models show how to limit global temperature rise to 1.5°C
5 Mar 2018 at 8:15am
There are several ways to limit global temperature rise to 1.5°C by 2100, and new research shows under what conditions this could happen.
