Eco-friendly biodiesel from palm oil?
27 Feb 2020 at 8:45am
Vegetable oil biofuels are increasingly used as an alternative to fossil fuels despite the growing controversy regarding their sustainability. In a study, researchers investigated the effect of palm-oil biodiesel on greenhouse gases for the entire life cycle. They found that using palm oil from first rotation plantations where forests were cleared for palms leads to an increase in greenhouse gas emissions compared to fossil fuels.
Motley crew: Rust and light a possible answer to the conundrum of hydrogen fu...
26 Feb 2020 at 10:13am
Production of hydrogen fuel is a key goal towards the development of sustainable energy practices, but this process does not have feasible techniques yet. Scientists have identified a novel technique of using rust and light to speed up hydrogen production from organic waste solution, a finding that can revolutionize the clean energy industry.

Engineers have developed eco-friendly-solvent processable hole transport polymers by using peppermint oil and walnut aroma food additives and the polymer can prevent lead leakage.
What to expect when you're expecting electric transportation
25 Feb 2020 at 7:13am
While electric vehicles alone may not reduce carbon emissions, a new study reveals that when electric vehicles are powered with renewable energy and coupled with carbon policy strategies, they can help combat climate change without sacrificing economic growth.
Quadrupling turbines, US can meet 2030 wind-energy goals
24 Feb 2020 at 3:34pm
The United States could generate 20% of its electricity from wind within 10 years, without requiring any additional land, according to new research.
Offshore wind farms could power much of coastal China
21 Feb 2020 at 1:07pm
If China is to meet and exceed its Paris Climate Agreement goal by 2030, it's going to need to find a way to increase its wind capacity. Researchers found that offshore wind could be a big part of the solution.
The climate and increased extreme weather affect our energy systems
20 Feb 2020 at 10:05am
Climate change, with more and more storms and heat waves, also has consequences for our energy supply. An international research team has now developed a new method for calculating how extreme weather affects energy systems.
Could water solve the renewable energy storage challenge?
19 Feb 2020 at 12:28pm
Seasonally pumped hydropower storage could provide an affordable way to store renewable energy over the long-term, filling a much needed gap to support the transition to renewable energy, according to a new study.
Barriers to development of seawater electrolysis technologies
19 Feb 2020 at 8:38am
Researchers have identified the key technological and scientific challenges of producing hydrogen through seawater electrolysis.
New world record for conversion of solar energy to electricity using quantum ...
18 Feb 2020 at 3:22pm
Researchers have set a world record for the conversion of solar energy to electricity via the use of tiny nanoparticles called 'quantum dots'. The technology has a huge range of potential applications, including the possibility to use it as a flexible, transparent skin to power cars, planes, homes and wearable technology.
New green technology generates electricity 'out of thin air'
17 Feb 2020 at 8:27am
Electrical engineers and microbiologists have created a device they call an 'Air-gen' or air-powered generator, with electrically conductive protein nanowires produced by the microbe Geobacter. The Air-gen connects electrodes to the protein nanowires in such a way that electrical current is generated from the water vapor naturally present in the atmosphere.
'Reverse fuel cell' converts waste carbon to valuable products at record rates
10 Feb 2020 at 8:22am
Fuel cells turn chemicals into electricity. Now, an engineering team has adapted technology from fuel cells to do the reverse: harness electricity to make valuable chemicals from waste carbon (CO2).
Oblique electrostatic inject-deposited TiO2 film for efficient perovskite sol...
10 Feb 2020 at 7:41am
The need to efficiently harvest solar energy for a more sustainable future is increasingly becoming accepted across the globe. A new family of solar cells based on perovskites -- materials with a particular crystal structure -- is now competing with conventional silicon materials to satisfy the demand in this area. Perovskite solar cells (PSCs) are continually being optimized to fulfill their commercial potential.
Next generation of greenhouses may be fully solar powered
7 Feb 2020 at 9:37am
Many greenhouses could become energy neutral by using see-through solar panels to harvest energy - primarily from the wavelengths of light that plants don't use for photosynthesis.
Lasers etch a 'perfect' solar energy absorber
4 Feb 2020 at 9:57am
Researchers demonstrate how laser etching of metallic surfaces creates the ''perfect solar energy absorber.'' This not only enhances energy absorption from sunlight, but also reduces heat dissipation at other wavelengths. The researchers also demonstrate solar energy harnessing with a thermal electric generator.
