Banking on sunshine: World added far more solar than fossil fuel power generating capacity in 2017

China leads with more than half of world's new solar capacity; global solar investment jumps 18 percent to $160.8 billion; cumulative renewable energy investment since 2004: $2.9 trillion

Solar energy dominated global investment in new power generation like never before in 2017.

The world installed a record 98 gigawatts of new solar capacity, far more than the net additions of any other technology -- renewable, fossil fuel or nuclear.

Nanoscale coating enables solar cells to absorb 20 percent more sunlight

Trapping light with an optical version of a whispering gallery, researchers at the National Institute of Standards and Technology (NIST) have developed a nanoscale coating for solar cells that enables them to absorb about 20 percent more sunlight than uncoated devices. The coating, applied with a technique that could be incorporated into manufacturing, opens a new path for developing low-cost, high-efficiency solar cells with abundant, renewable and environmentally friendly materials.

Iran absorbs $2.5bn in renewable energy sector in 5 years

In the last five years, $2.5 billion has been invested in the country’s renewable energy sector.

According to reports by the Ministry of Energy, 70 percent of the resources which amount to $1.75 billion have been funded by foreign investment and the remaining 30 percent amounting to $750 million from domestic investment.

By 2013, 165MW renewable power stations were established in Iran, with 131MW by public funds and 34MW by the private sector.

Ancient paper art, kirigami, poised to improve smart clothing

Scientists describe how kirigami has inspired its efforts to build malleable electronic circuits. Their innovation -- creating tiny sheets of strong yet bendable electronic materials made of select polymers and nanowires -- could lead to improvements in smart clothing, electronic skin and other applications that require pliable circuitry.

Like a yoga novice, electronic components don't stretch easily. But that's changing thanks to a variation of origami that involves cutting folded pieces of paper.

Electric textile lights a lamp when stretched

Working up a sweat from carrying a heavy load? That is when the textile works at its best. Researchers at the Chalmers University of Technology have developed a fabric that converts kinetic energy into electric power, in cooperation with the Swedish School of Textiles in Borås and the research institute Swerea IVF. The greater the load applied to the textile and the wetter it becomes the more electricity it generates. The results are now published in the Nature Partner journal Flexible Electronics.

Obtaining energy from marine currents

Researchers from Universidad Politécnica de Madrid (UPM) have developed procedures and designs to obtain energy from marine currents in areas of great depths optimizing the costs.

Finland, Denmark, Sweden Sign Cooperation Document with Iran’s IDRO

“Finland, Denmark, and Sweden signed a MoU with IDRO of Iran to promote collaboration in the fields of oil & gas, high-tech, transportation, renewable energies, manager training, industrial renovation, steel, water, investment, and finance,” Keijo Norvanto tweeted on Sunday.

The memorandum of understanding was signed in Tehran on Sunday with Ali Araqchi, the head of IDRO’s International Affairs Department, Swedish Ambassador to Iran Helena Sangeland, Norvanto and Denmark’s Ambassador to Iran Danny Annan in attendance.

New dual-atom catalyst shows promise to yield clean energy by artificial photosynthesis

An international team of researchers has synthesized a dispersed catalyst featuring two atoms, yielding a stable and highly active platform that could facilitate solar water oxidation for the production and storage of clean energy, the team reports.

Looking for new solutions to more efficiently harvest and store solar energy, scientists from the U.S. and China have synthesized a new, dual-atom catalyst to serve as a platform for artificial photosynthesis, the team reported today in the Proceedings of the National Academy of Sciences.

The 12th Specialized Monitoring and Troubleshooting Conference was held with the participation of professors and specialists in the field of industry and knowledge.

The conference was held with the goals of developing knowledge and technology based on state of the art, identification of various methods of troubleshooting and non-destructive testing and converting experiences in industrial and academic sectors.Ali Farhur, Shahid Rajaee Power Plant Director, delivered a speech focused on the issue of monitoring the situation, the executive arm of senior executives.

Wind and solar power could meet four-fifths of US electricity demand, study finds(Investment in greater storage, transmission capabilities needed)

The United States could reliably meet about 80 percent of its electricity demand with solar and wind power generation, according to scientists at the University of California, Irvine; the California Institute of Technology; and the Carnegie Institution for Science.

However, meeting 100 percent of electricity demand with only solar and wind energy would require storing several weeks' worth of electricity to compensate for the natural variability of these two resources, the researchers said.
