The world's need for fuel will persist also when Earth's deposits of fossil fuels run out.
Bioethanol which is made from the remains of plants after other parts have been used as food or other agricultural products and therefore termed second generation is seen as a strong potential substitute candidate
Since 2010 it has been mandatory in Denmark to add five per cent ethanol to all gasoline sold in the country.
You can add up to 85 per cent bioethanol to gasoline and this is common in several South american countries.
Danish research institutions and DONG Energy (denmark) have great focus on how to produce bioethanol from otherwise useless crop residues such as straw.
The use of bioethanol instead of gasoline reduces the CO2 emissions from cars and fossil fuel consumption.
oil-producing cropa multi-institutional team reports that it can increase sugarcane's geographic range boost its photosynthetic rate by 30 percent
and turn it into an oil-producing crop for biodiesel production. These are only the first steps in a bigger initiative that will turn sugarcane
and sorghum--two of the most productive crop plants known--into even more productive oil-generating plants.
The team will present its latest findings Tuesday (Feb 25) at the U s. Department of energy's ARPA-E Energy Innovation Summit in Washington D c. Biodiesel is attractive
because for example with soybean once you've pressed the oil out it's fairly easy to convert it to diesel said Stephen P. Long a University of Illinois professor of plant biology and leader of the initiative.
But soybean isn't productive enough to meet the nation's need for renewable diesel fuels Long said.
and if you could make them accumulate oil in their stems instead of sugar this would give you much more oil per acre he said.
and later with sugarcane the team introduced genes that boost natural oil production in the plant.
They increased oil production in sugarcane stems to about 1. 5 percent. That doesn't sound like a lot
but at 1. 5 percent a sugarcane field in Florida would produce about 50 percent more oil per acre than a soybean field Long said.
There's enough oil to make it worth harvesting. The team hopes to increase the oil content of sugarcane stems to about 20 percent he said.
Using genetic engineering the researchers increased photosynthetic efficiency in sugarcane and sorghum by 30 percent Long said.
Our goal is to make sugarcane produce more oil be more productive with more photosynthesis
#Sustainable use of available energy wood resources in Northwest Russia promises significant social, economic opportunitiesnowadays humanity faces many challenges;
Intensification of forestry in Russia will result in increasing availability of wood for material and energy uses.
A doctoral dissertation completed at the University of Eastern Finland analyzed the potential of energy wood resources in the Leningrad region of Russia at regional and district levels.
The study discovered significant potential for the intensification of energy wood supply in the Leningrad region of Russia.
Maximization of sustainable energy wood supply will create new working places and business opportunities. However several challenges like low productivity of felling operations and technical accessibility of forests have to be solved to intensify energy wood supply in the regions.
The availability of energy wood depends on the actual volumes of annual fellings and is affected by technical socioeconomic and climatic issues.
These factors were considered when three scenarios of wood availability were analyzed to compare the efficiency of wood supply chains to estimate employment effects of forest chip production
The impact of climate change on the technical accessibility of forests and harvestable volumes of industrial and energy wood was analyzed also.
The Recent scenario reflects the potential of energy wood taking into account the intensity of fellings
The Allowable scenario shows the potential of energy wood assuming full utilization of the annual allowable cut based on current logging technology
The''Potential''scenario shows availability of energy wood resources in the case of intensified forest management which means a significant increase in thinnings full utilization of annual allowable cut based on
The analysis showed that intensification of forestry in the region could significantly increase availability of energy wood.
In the scenario Allowable the availability of energy wood increased from 4. 1 to 6. 3 Mm3(+54%)compared with the scenario Recent.
In the scenario Potential the total volume of available energy wood would be 9. 2 Mm3(+124%compared with scenario Recent.
Therefore in the conditions of the study area forest chips were a relatively expensive fuel due to the high costs of felling
Forest chips were 2-3 times more expensive than natural gas and coal but cheaper than heavy oil.
The employment effect from the utilization of energy wood depended on the availability scenarios and the type of chipper used.
The study area has large available volumes of energy wood but their utilization is limited by technical and economic factors.
and local authorities predict economic and social effects from the utilization of energy wood. Story Source:

The contribution of the cap is the elastic curvature energy and then you just forget it Penev said.
One is the energy portion dictated by the catalyst; another one may be the energy of the caps per se.

A nanotube is an atom-thick sheet of carbon atoms arranged in hexagons and rolled into a tube.
This study showed the energy involved in configuring the cap is reasonably flat he said.

To nourish its mass an animal needs fuel. Burning that fuel generates heat. The animal has to find a way to get rid of excess body heat.
The obvious way is surface cooling. But because the tiger's surface area is proportionally smaller than its mass the surface is not up to the task.

#Environmental impact of Ontario corn production assessedresearchers at the University of Guelph examined the energy use
The study reports estimated county-level energy and GHG intensity of grain corn stover and cob production in Ontario from 2006-2011.
According to the paper's authors most of the energy used during corn production comes from the use of natural gas
and the use of diesel fuel during field work. Corn is a major economic crop in North america and the renewable fuels developed from corn production are used frequently to mitigate the GHG emissions from fossil fuel use explained Susantha Jayasundara lead author of the paper.
Assessing the GHG and energy intensity of corn production helps identify opportunities for efficiency and aids in improving the GHG mitigation potential of corn-derived renewable fuels continued Jayasundara.
The authors note that reducing GHG intensity and improving energy efficiency during corn production can be achieved through the use of field-drying corn hybrids reduced tillage and diminished nitrogen inputs.
The article Energy and Greenhouse Gas Intensity of Corn (Zea mays L.)in Ontario: A regional assessment by Susantha Jayasundara Claudia Wagner-Riddle Goretty Dias and Kumudinie Kariyapperuma is available Open Access in the Canadian Journal of Soil science.
Given the environmental and economic benefits of renewable fuels and the proliferation of their use in Canada it is important to more fully understand the environmental impacts of their associated agricultural production added Serge Buy CEO of AIC.

and energy has to leave the ocean through evaporation he explained. If you think about all the ice on top of Mt everest--who took this huge amount of material up there?
There's energy in evaporation but it's so subtle we don't see it. But until now no one has tapped that energy to generate electricity.
As Sahin pursued the idea of a new humidity-driven generator he realized that Mahadevan had been investigating similar problems from a physical perspective.
since they shrink reversibly they had to be storing energy. In fact spores would be particularly good at storing energy
because they are rigid yet still expand and contract a great deal the researchers predicted. Since changing moisture levels deform these spores it followed that devices containing these materials should be able to move in response to changing humidity levels Mahadevan said.
When Sahin first set out to measure the energy of spores he was taken by surprise. He put a solution thick with spores on a tiny flexible silicon plank expecting to measure the humidity-driven force in a customized atomic force microscope.
and adhesive tape stored energy settling on rubber as the most promising material. Then he built a simple humidity-driven generator out of Legosâa miniature fan a magnet and a spore-coated cantilever.
Sahin's prototype captures just a small percentage of the energy released by evaporation but it could be improved by genetically engineering the spores to be stiffer and more elastic.
Indeed in early experiments spores of a mutant strain provided by Driks stored twice as much energy as normal strains.
Solar and wind energy fluctuate dramatically when the sun doesn't shine or the wind doesn't blow
