In fact in some regions the magnitude of carbon uptake or release due to the effects of specific animal species or groups of animals--such as the pine beetles devouring forests in western North america--can rival the impact of fossil fuel
In one case an unprecedented loss of trees triggered by the pine beetle outbreak in western North america has decreased the net carbon balance on a scale comparable to British columbia's current fossil fuel emissions.

Once the regulating function of Trx f in starch synthesis had been proven the researcher focussed on its possible application in energy crops used to produce bioethanol:
With these sugars which could later be turned into bioethanol one could obtain up to 40 litres of bioethanol per tonne of fresh leaves--according to the theoretical calculation provided by the National Centre for Renewable Energies where the enzymatic test was conducted

Existing air quality regulations and trends in clean energy technology are expected to reduce the amount of harmful nitrogen oxides (NOX) emitted by coal plants and cars over time.
*Carbyne chains can take on side molecules that may make the chains suitable for energy storage.*
It could be useful for nanomechanical systems in spintronic devices as sensors as strong and light materials for mechanical applications or for energy storage.
Based on the calculations he said carbyne might be the highest energy state for stable carbon.

But nobody asks about the highest energy configuration. We think this may be it a stable structure at the highest energy possible.
Theories about carbyne first appeared in the 19th century and an approximation of the material was synthesized first in the USSR in 1960.
Another finding of great interest was the energy barrier that keeps atoms on adjacent carbyne chains from collapsing into each other.

On average in the United states electric urban delivery trucks use about 30 percent less total energy and emit about 40 percent less greenhouse gases than diesel trucks for about the same total cost taking into account both the purchase price
The relative benefits of the electric vehicles the researchers found depend on vehicle efficiency associated with drive cycle diesel fuel price travel demand electric drive battery replacement
Vehicles operated in states heavily dependent on coal for producing electricity showed higher emissions. In every state in the U s. electric trucks provided some reduction in greenhouse gas emissions with urban routes providing the most advantage.
Wild cards in the study included the future costs of both diesel fuel and electricity and the potential cost of replacing an electric truck's battery pack
while only diesel fuel prices could have a similarly large effect on the future cost-competitiveness of diesel trucks.

Using coal to make natural gas may be good for China's energy security but it's an environmental disaster in the making said Robert B. Jackson Nicholas Professor of Environmental sciences
As part of the largest investment in coal-fueled synthetic natural gas plants in history the central Chinese government recently has approved construction of nine large-scale plants capable of producing more than 37 billion cubic meters
if the gas produced by the new plants is used to generate electricity the total lifecycle greenhouse gas emissions would be 36 percent to 82 percent higher than pulverized coal-fired power.
If the synthetic natural gas made by the plants were used to fuel vehicles the lifecycle greenhouse gas emissions would be twice as large as from gasoline-fueled vehicles.
While we applaud China's rapid development in clean energy we must be cautious about this simultaneous high-carbon leapfrogging.

Per unit energy the carbon dioxide emissions from burning ethanol are just 2 percent lower than those from gasoline.
Biodiesel yields carbon dioxide emissions about 1 percent greater than those from petroleum diesel. If there is any climate benefit to biofuels it occurs
Corn ethanol production of 14 billion gallons supplied 4. 4 percent of total U s. transportation liquid fuel use in 2011.
However even that small share of liquid fuel supply required 45 percent of the U s. corn crop.
Biofuels are presumed the replacement for the petroleum-based transportation fuels gasoline and diesel that dominate liquid fuel use.
In the United states the federal Renewable Fuel Standard mandates a large increase in biofuels use which has reached now 16 billion gallons a year mainly ethanol.
But Decicco pointed out that a recent National Academy of Sciences report concluded that the Renewable Fuel Standard may not reduce greenhouse gas emissions at all once global impacts are counted.

So when a muscle is contracting it is acting more like a spring waiting to release its energy than a motor.
This energy transfer process allows the moth to fly without expending a large amount of energy. Daniel says that the presence of elastic energy was not a surprise.
The energy cost of rapidly accelerating and decelerating wings during flight is enormous and no insect would be able to maintain that kind of energy output.
However this study uncovers a new mechanism for this elastic energy storage one based on temperature differences.

Analysis of the 410 spoonable foods revealed that their energy content (282 kilojoules per 100 grams) was almost identical to that of breast milk (283kj/100g.
Dry finger foods had a much higher energy and nutrient density overall but they were also particularly high in sugar.
But it still means that 50g of a spoonable family food would probably supply the same amount of energy

and E coli bacteria have joined forces to turn tough waste plant material into isobutanol a biofuel that matches gasoline's properties better than ethanol.
We're hoping that biofuels made in such an efficient way can eventually replace current petroleum-based fuels said Xiaoxia Nina Lin assistant professor of chemical engineering and leader of the research.
Gallon for gallon isobutanol gives off 82 percent of the heat energy gasoline provides when burned compared to ethanol's 67 percent.
While ethanol serves as a mixer in the gasoline infrastructure today many researchers argue that isobutanol could be a replacement.
so fuel production won't drive up food costs. Lin's team used corn stalks and leaves but their ecosystem should also be able to process other agricultural byproducts and forestry waste.
They also converted a large proportion of the energy locked in the corn stalks and leaves to isobutanol--62 percent of the theoretical maximum.
Minty and others in Lin's group are now trying to improve on their energy conversion rate
The fuel is toxic but higher concentrations will drive down the cost of isolating the fuel.
We're really excited about this technology Minty said. The U s. has the potential to sustainably produce 1 billion tons
or more of biomass annually enough to produce biofuels that could displace 30 percent or more of our current petroleum production.
Moreover by engineering the bacteria differently they believe their system could produce a variety of petroleum-based chemicals in a sustainable way.

pathway of lignin a major component of plant secondary cell walls that limits the conversion of biomass to energy.
and has the potential to greatly increase the efficiency of energy crop conversion for biofuels said Sally M. Benson director of Stanford university's Global Climate and Energy Project.
Lignin as a barrierto understand how plant cells can deliver fuel or plastics a basic knowledge of a plant's cell wall is needed.
The lignin cement has to be removed via an energy-consuming and environmentally unfriendly process. Plants with a lower amount of lignin or with lignin that is easier to break down can be a real benefit for biofuel and bioplastics production.
These new insights published this week online in Science Express can now be used to screen natural populations of energy crops such as poplar eucalyptus switchgrass or other grass species for a nonfunctional CSE gene.
Alternatively the expression of CSE can be engineered genetically in energy crops. A reduced amount of lignin or an adapted lignin structure can contribute to a more efficient conversion of biomass to energy.
