This research was presented at a press conference by Peter Lund of the Helsinki University of Technology's Advanced Energy Systems in Espoo, Finland, ahead of the scheduled congress session titled, "Renewable Energies: How Far Can They Take Us?"
"Our findings demonstrate that with global political support and financial investment, previous notions that the potential for renewables was in some way limited to a negligible fraction of world demand were wrong," said Lund. "If we prioritize and recognize the value of renewable energy technologies, their potential to supply us with the energy we need is tremendous."
Previous projections put renewables' share at only 12 percent by 2030. Other research within the same congress session further supports the viability of renewables, examining closely the limitations and potential of wind, biomass and biofuels.
According to Erik Lundtang Petersen of Risoe DTU's Wind Energy Department in Roskilde, Denmark, in order for the wind sector to deliver its full potential, it must focus on efficiently delivering, installing and connecting large amounts of wind power to the grid, with strong concern for reliability, availability and accessibility of the turbines.
"We have identified specific areas of priority for the wind sector to effectively deliver the overall objective of cost reductions," said Petersen. "Research areas including turbine technology, wind energy integration and offshore deployment will be crucial to maximizing future growth."
Within biofuels and biomass, research conducted by Jeanette Whitaker of the Centre for Ecology and Hydrology in Lancaster, UK found that second generation biofuels, such as ethanol from woody crops/straw, had substantially lower energy requirements and greenhouse gas emissions than first generation biofuels, such as ethanol made from foodstuffs, for example wheat and sugar beet.
"These findings are important and relevant, as the current biofuel debate has centered on the issue of the competing need for crops to be used for food versus fuel," said Whitaker.
All of these findings and hundreds more are being presented by thousands of climate researchers from more than 70 countries at "Climate Change: Global Risks, Challenges & Decisions" taking place in Copenhagen, Denmark, 10-12 March 2009 (www.climatecongress.ku.dk).
The purpose of the congress is to deliver an update on our knowledge of climate change and how to address the risks and opportunities ahead. The results will be presented to world leaders as they gather later this year in Copenhagen for the post-Kyoto negotiations at the United Nations Climate Change Conference (COP15).

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
