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.
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.

The solar steam sterilization system uses nanomaterials to convert as much as 80 percent of the energy in sunlight into germ-killing heat.
The technology has an overall energy efficiency of 24 percent. Photovoltaic solar panels by comparison typically have an overall energy efficiency of around 15 percent.
When used in the autoclaves in the tests the heat and pressure created by the steam were sufficient to kill not just living microbes but also spores and viruses.

experts saythe U s. Department of energy has announced that it wants to establish minimum energy efficiency standards for all computers
and greenhouse gas emissions sharply with off-the-shelf equipment and proven energy management practices. Most big data centers the global backbone of the Internet could slash their greenhouse gas emissions by 88 percent by switching to efficient off-the-shelf equipment and improving energy management according to new research.
The carbon emissions generated by a search on Google or a post on Facebook are related mostly to three things:
and in some cases to be as high as 80 percent said Koomey a research fellow at Stanford university's Steyer-Taylor Center for Energy Policy
and operate the equipment are often not accountable for energy costs or efficiency--a major institutional barrier to sustainable computing.
and the energy management practices are understood well. This principal-agent problem applies elsewhere in energy too.
Who designs and builds your cable box? The cable company. Who pays the electric bill? You do said Koomey.
State-of-the-art data centers have reduced the ratio to about 1 to 0. 1 kwh said study co-author Arman Shehabi of Lawrence Berkeley National Laboratory's Environmental Energy Technologies Division.
Of the potential 88 percent reduction in greenhouse gas emissions though IT device efficiency accounts for about 80 percent and facility energy management for only about 8 percent.
Policymakers and environmental organizations however tend to focus on the third option--renewable energy which the study finds to be misplaced a priority.
For data centers as for all uses of energy efficiency is always the first thing to do. It's cheapest
So high-energy data centers that pay their utilities a premium for renewable power unnecessarily tie up low-carbon electrons that might otherwise be used to reduce emissions from other customers.
#Climate change could deprive Volta Basin of water needed to boost energy and food productiona new study released today finds that so much water may be lost in the Volta River basin due to climate change that planned hydroelectric projects to boost energy

Clemens did acknowledge many variables can impact how efficiently the body extracts energy from plant-based foods
and ingredients could contribute to more appropriate energy values and more accurate product labeling. We may see a resurgence of digestibility studies in humans rather than relying on estimates by Atwater that we have been doing for a number of years said Malden Nesheim (CQ) provost emeritus and professor of nutrition emeritus Cornell University Ithaca NY.

#Surviving fasting in the coldking penguin chicks survive harsh winters with almost no food by minimising the cost of energy production.
however they experience a severe energy challenge during the cold sub-Antarctic winter when food is not readily available.
This indicates that less substrate/oxygen was consumed to produce the same amount of energy in the form of ATP showing that mitochondria from fasted chicks adjust its functioning to minimize the cost of energy production.
This study shows how king penguins are able to produce heat to survive the cold without depleting their energy stores an essential mechanism to survive the cold
Fasting in the cold represents a bioenergetics trade-off between sparing energy for body maintenance
and dissipating energy for heat production and endothermy maintenance. In this challenging context chicks develop a whole range of energy sparing mechanisms (social huddling behaviour reduction in muscle activity
and basal metabolic rate short period of hypothermia and high thermal insulation) that lead to reduce the energy allocated to heat production and growth.

In addition to providing nitrogen and key vitamins the bacteria appear to help the fungus access energy-rich cellulose by breaking apart other plant polymers that encase it such as hemicellulose.

Implementing standard energy-efficiency practices focused on refrigeration and compressed-air systems motors and lighting will also lead to reduction.

This breakdown is expected for more complex products such as electronics where the energy that goes into manufacturing fine integrated circuits can outweigh the energy expended in processing raw materials.
Olivetti Kirchain and their colleagues found that for these small light components such processes are energy-intensive
--and therefore carbon-intensive--compared with the energy that goes into making shoe materials such as polyester and polyurethane.
For example running shoes unlike electronics require very little energy to use aside from the energy needed to infrequently wash the shoes.
While part of the manufacturing footprint is attributable to a facility's energy source other emissions came from processes such as foaming
which expend large amounts of energy in the manufacture of small lightweight parts. As Kirchain explains it You have a lot of effort going into the molding of the material
