(Press-News.org) To cost‑effectively protect the climate, not only an emissions
trading scheme but also financial support for new technologies is
needed. Economising on targeted funding, for example for renewable
energies, makes climate protection more expensive ‑ as scientists of
the Potsdam Institute for Climate Impact Research (PIK) now
calculated for the first time, using a complex computer simulation
that spans the entire 21st century. Without funding, energy
technologies with high cost reduction potentials will hardly stand a
chance, since they require a significant initial investment: a case
of market failure.
"Companies in the global energy sector often rely on familiar technologies instead of striving for innovation – they are more hesitant than companies in other industries, our analysis shows," says Matthias Kalkuhl, lead author of the study published in the scientific journal Resource and Energy Economics. Behind this behaviour stands not just inertia. Pioneers are paying the bill for the development and the risk of innovation, whose results are beneficial to everyone, and are then copied by competitors. Additionally, there is uncertainty for companies about the long term profitability of investments into new technologies, since the political framework – for example future CO2 emission prices – is unreliable: "The result is a self-reinforcing lock-in effect," explains Kalkuhl. "Inferior and therefore more expensive technologies dominate the market for decades. From a management point of view, it is rational. But economically it is fatal."
The reason for this particular restraint of the energy sector is this: the product – electricity or heat – is the same to the consumer, no matter which technology was used to produce it, according to Kalkuhl. As the product is homogenous, consumers have a low incentive to pay a significantly higher price for an innovative technology. This is in stark contrast to the case of smart phones or e-book readers. These can successfully capture new markets with clever product differentiation.
Effective political actions to promote new technologies, the computer simulation shows, are a feed-in tariff or quotas for energy produced by particular technologies. According to the scientists, only funding targeted at emerging technologies is effective: offshore wind power, usage of biomass, solar energy. The cost-benefit ratio is especially positive, if the financial support is limited to a period of, for example, 30 years. However, it is not economically beneficial to support already well-developed CO2-reducing technologies: nuclear reactors, water power, or highly efficient gas power plants.
For their analysis, the scientists have designed a new computer model which calculates the interplay of companies, households, and political actors as well as the resulting welfare effects. This so-called dynamic multi-agent model "shows robust results for a big range of scenarios, even though we had to include a few simplifications," says Kalkuhl. The model assumes a working emissions trading scheme with ambitious climate protection targets which promotes low carbon technologies.
The results are in contrast to conventional economic wisdom that emissions trading paired with technology funding is an inefficient duplication, and that innovation is sufficiently ensured by patent protection and general research funding. "We found that although it is possible to reduce the greenhouse gas emissions through emissions trading only, this is at a higher cost," says Ottmar Edenhofer, chief economist of PIK and co-author of the study. Only targeted funding "can introduce new technologies to the market which then show a steep learning curve - in other words which improve and become cheaper quickly." Higher costs make political measures to protect the climate more difficult to achieve, thus making emissions trading and technology funding two sides of the same coin.
The effects only show up when the investment behaviour of many decades is taken into account. Previous studies were often only on the short term. "But climate policy is a long-term project," says Edenhofer. The government does not know any better than the companies which technologies are viable, but especially because of this uncertainty, it is the only player who can afford funding technology. However, without the introduction of a price on CO2 emissions paired with an emissions' cap, even the best technology funding is, says Edenhofer, rather useless. "Fighting climate change with subsidies only is simply not affordable."

Using this garment-based patient biomonitoring platform allows us to register a number of the patient's physiological parameters in a non-intrusive manner. "The information gathered by an intelligent t-shirt using e-textile technology is sent, without using wires, to an information management system, which then shows the patient's location and vital signs in real time", explain the UC3M researchers. The system is designed to be used in hospitals and can be divided into two parts: the fixed infrastructure, which would be pre-installed in the hospital, and the mobile units, ...
For the first time, a major cultural institution is leveraging four Guide by Cell mobile technologies to provide a wide range of interactive choices for the visitor experience.
This summer, San Francisco's Fort Mason Center launched the year-long "SEAT" exhibition featuring over 30 Bay Area artists, each creating their own interpretation of a "seat."
SEAT is the first exhibition in the country to integrate the full Guide by Cell suite of mobile services. The SEAT works, built by local architects, concrete designers, blacksmiths, woodworkers, ...
In biologically active enzyme substrate compounds, as can be found in medicines, water plays a more decisive role than has been imagined up to now. The surrounding water acts like an "adhesive", in order to keep the substrate at the right place on an enzyme. For this, the dynamism of the water is retarded. Scientists at the RUB under Prof. Dr. Martina Havenith (Physical Chemistry) in close cooperation with the group of Prof. Irit Sagi from the Israeli Weizmann Institute have been able to observe and prove the retardation of the water's dynamism "live" for the first time ...
Premium knee implants, such as high-flexion knees were created to address specific patient needs and to promote additional function. But whether these higher cost devices provide greater longevity than their standard lower-cost counterparts remains to be seen in the medical literature.
Studies that have evaluated the functional results of premium vs. standard implants have demonstrated similar results between the prostheses.
Since the Zimmer NexGen knee replacement system has been on the market, almost half a million people in the US alone have had Zimmer knee implants. ...
Ovarian cancer is one of the most frequent forms of cancer that affect women. As tumors can initially grow unchecked in the abdomen without causing any major symptoms, patients are usually diagnosed at an advanced stage and have to undergo surgery plus chemotherapy. During the operation, surgeons attempt to remove all tumor deposits as this leads to improved patient prognosis. To do this, however, they primarily have to rely on visual inspection and palpation - an enormous challenge especially in the case of small tumor nests or remaining tumor borders after the primary ...
Research by the University of Liverpool has found that intervention policies that promote healthy eating could cut the death rate for cardiovascular disease (CVD) by up to 50%.
Professor Simon Capewell from the Institute of Psychology, Health and Well-being found that intervention policies which reduce unhealthy eating habits can have a significant effect on levels of CVD at both an individual and population level.
Poor diet is one of the major causes of CVD and small improvements can make a positive and rapid impact on both the individual and the wider population. ...

Researchers from North Carolina State University are proposing a health-based approach to identifying groups at high risk of genocide, in a first-of-its-kind attempt to target international efforts to stop these mass killings before they start.
Genocide, or the willful attempt to exterminate a specific population, is a violation of international law. In recent years, international discussion of genocide has focused in part on finding ways to identify populations at risk in order to prevent a problem before it starts.
Some risk factors have already been identified, such ...
Today's economic climate is having a dramatic effect on the health and well-being of injured workers. Skyrocketing unemployment rates and a 15% poverty level is a very scary realization. The impact it is having on injured workers is twofold.
First, an employee that gets injured is typically living on a budget. If he/she gets injured, that employee will have to readjust that budget to compensate for the reduction in income. Workers' Compensation benefits in Pennsylvania pay between Ninety Percent (90%) and Sixty-Six and Two-Thirds (66 2/3%) of the gross wage. This benefit ...
Common genetic variants contribute to the risk of schizophrenia and bipolar disorder, an international research consortium has discovered.
Schizophrenia and bipolar disorder are common and often devastating brain disorders, affecting around one per cent of the world's population. A team including Cardiff University scientists has found new molecular evidence that 11 genetic regions have strong links with these diseases, including six regions not previously observed. The researchers also found that many of these DNA variations contribute to both diseases.
The findings, ...
