Lighting the path to renewable energy
19 Sep 2019 at 6:39am
Scientists have developed a novel, standardized way of quantifying and comparing these variations in solar power. The new study may help guide the development and performance of solar photovoltaic farms -- systems that harness the sun's energy and convert it to electricity.
Cutting emissions gradually will avert sudden jump in warming
18 Sep 2019 at 1:16pm
Steadily reducing fossil fuel emissions over coming years will prevent millions of premature deaths and help avoid the worst of climate change without causing a large spike in short-term warming that some studies predict, new analysis from finds. The finding dispels the misconception that the air-quality and climate benefits of transitioning to clean energy play out at different timescales -- a sticking point in recent climate negotiations.
Welcome indoors, solar cells
16 Sep 2019 at 7:19am
Scientists have developed organic solar cells optimized to convert ambient indoor light to electricity. The power they produce is low, but is probably enough to feed the millions of products that the internet of things will bring online.
Researchers design a roadmap for hydrogen supply network
12 Sep 2019 at 9:48am
Researchers have developed a hydrogen supply chain model that can enable the adoption of zero-emission, hydrogen-powered cars -- transforming them from a novelty into everyday transportation in just 30 years.
How much photovoltaics (PV) would be needed to power the world sustainably?
11 Sep 2019 at 7:15am
The International Energy Agency has dubbed increased global cooling demand as one of the most critical blind spots in today's energy debate.
Colorful microreactors utilize sunlight
10 Sep 2019 at 7:53am
The sun is the most sustainable energy source available on our planet and could be used to power photochemical reactions. Scientists now present a widely applicable, cost-effective photomicroreactor. It is based on ''Luminescent Solar Concentrators'', which harvest, convert, and make photons available for chemical reactions. Thus, the researchers were able to synthesize various substances, including two pharmaceuticals.
Reactor turns greenhouse gas into pure liquid fuel
3 Sep 2019 at 5:40am
An electrocatalysis reactor built at Rice University recycles carbon dioxide to produce pure liquid fuel solutions using electricity. The scientists behind the invention hope it will become an efficient and profitable way to reuse the greenhouse gas and keep it out of the atmosphere.
Would a carbon tax help to innovate more-efficient energy use?
27 Aug 2019 at 8:11am
Taxing carbon emissions would drive innovation and lead to improved energy efficiency, according to a new article.
Laser printing tech produces waterproof e-textiles in minutes
27 Aug 2019 at 7:16am
In just three minutes, the laser printing approach can produce a 10x10 cm smart textile patch that's waterproof, stretchable and easily integrated with solar or other sources of power.
Harnessing the power of solar panels
27 Aug 2019 at 5:47am
Researchers have developed a way to better harness the volume of energy collected by solar panels. In a new study, the researchers developed an algorithm that increases the efficiency of the solar photovoltaic (PV) system and reduces the volume of power currently being wasted due to a lack of effective controls.
Cost-effective fuel cell technology
20 Aug 2019 at 10:09am
Researchers have identified ammonia as a source for engineering fuel cells that can provide a cheap and powerful source for fueling cars, trucks and buses with a reduced carbon footprint.
Materials that can revolutionize how light is harnessed for solar energy
19 Aug 2019 at 8:27am
Scientists have designed organic molecules capable of generating two excitons per photon of light, a process called singlet fission. The excitons can live for much longer than those generated from their inorganic counterparts, which leads to an amplification of electricity generated per photon that is absorbed by a solar cell.
Europe has the untapped onshore capacity to meet global energy demand
14 Aug 2019 at 5:12am
Europe has the capacity to produce more than 100 times the amount of energy it currently produces through onshore windfarms, new analysis has revealed.
Key factors in how some algae harness solar energy
13 Aug 2019 at 10:42am
Scientists have discovered how diatoms -- a type of alga that produce 20 percent of the Earth's oxygen -- harness solar energy for photosynthesis. The discovery could help lead to more efficient and affordable algae-based biofuels and combat climate change from fossil fuel burning.
Growth of wind energy points to future challenges, promise
13 Aug 2019 at 8:22am
Advances in adapting the technology and better methods for predicting wind conditions have fanned significant growth of the use of wind turbines for electricity in the last 40 years. A new report takes stock of where the field is now and what lies ahead. Researchers surveyed the growth of wind technology as a source of renewable energy and assessed its viability for continuing to capture larger shares of the electricity market.
