@mike13323 Solar panels pay back there energy usage in two years but last 40+years. About 85%of the oxygen comes from the oceans.
There is also the large energy debt they come with. As far as AGW proponents are concerned that means extra carbon burned
in order to produce this non-carbon energy source. After 30+years of this stuff the solar panels are just starting to break even on that front.
I want the our energy to be cleaner and safer for the environment however until technology catches up with fossil fuels it's prudent to scale back slowly and responsibly.

concrete requires five times steel 24 times and aluminum 126 times. Wood also performs better: It is for example five times more insulative than concrete and 350 times more so than steel.
That means less energy is needed to heat and cool a wood building. When CLT is used to build high-rise towers the carbon savings can be enormous.

The study published in a special issue of the journal Climatic Change provides an overview of the results of EMF27 a major research project combining 18 different global energy-economy models from research teams around the world.
In 2010 coal oil and gas supplied more than 80%of the world's total primary energy supply
--and the demand for energy is projected to increase by 2 to 3 times by 2100.
The EMF27 study shows that without policies to cut greenhouse gas emissions fossil fuels will remain the major energy source in 2100 with resulting increases in greenhouse gas emissions.
Bioenergy is an especially valuable energy resource because unlike solar wind and hydro power it can be converted into liquid and gaseous fuels

#Breakthrough in hydrogen fuel production could revolutionize alternative energy marketa team of Virginia Tech researchers has discovered a way to extract large quantities of hydrogen from any plant a breakthrough that has the potential to bring a low-cost environmentally friendly fuel source
The U s. Department of energy says that hydrogen fuel has the potential to dramatically reduce reliance of fossil fuels
but not affiliated with this project said this discovery has the potential to have a major impact on alternative energy production.
and energy companies are working on hydrogen fuel cell vehicles as the transportation of the future Zhang said.
The energy stored in xylose splits water molecules yielding high-purity hydrogen that can be utilized directly by proton-exchange membrane fuel cells.
Even more appealing this reaction occurs at low temperatures generating hydrogen energy that is greater than the chemical energy stored in xylose and the polyphosphate.
This results in an energy efficiency of more than 100 percent--a net energy gain. That means that low-temperature waste heat can be used to produce high-quality chemical energy hydrogen for the first time.
Other processes that convert sugar into biofuels such as ethanol and butanol always have energy efficiencies of less than 100 percent resulting in an energy penalty.
We think this discovery is a game-changer in the world of alternative energy. Support for the current research comes from the Department of Biological Systems Engineering at Virginia Tech.

#Global natural gas boom alone wont slow climate changea new analysis of global energy use economics
But in the long run according to this study a global abundance of inexpensive natural gas would compete with all energy sources--not just higher-emitting coal
but also lower-emitting nuclear and renewable energy technologies such as wind and solar. Inexpensive natural gas would also accelerate economic growth
and expand overall energy use. The effect is that abundant natural gas alone will do little to slow climate change said lead author Haewon Mcjeon an economist at the Department of energy's Pacific Northwest National Laboratory.
Global deployment of advanced natural gas production technology could double or triple the global natural gas production by 2050
but greenhouse gas emissions will continue to grow in the absence of climate policies that promote lower carbon energy sources.
Their computer models included not just energy use and production but also the broader economy and the climate system.
These integrated assessment models accounted for energy use the economy and climate and the way these different systems interact with one another.
even though it was dramatically changing the global energy system said James Jae Edmonds PNNL's chief scientist at JGCRI.
and use energy from all sources affect emissions in several ways: â#¢Natural gas replacing coal would reduce carbon emissions.
But due to its lower cost natural gas would also replace some low-carbon energy such as renewable or nuclear energy.
In a sense natural gas would become a larger slice of the energy pie. â#¢Abundant less expensive natural gas would lower energy prices across the board leading people to use more energy overall.
In addition inexpensive energy stimulates the economy which also increases overall energy use. Consequently the entire energy pie gets bigger. â#¢The main component of natural gas methane is a more potent greenhouse gas than carbon dioxide.
During production and distribution some methane inevitably escapes into the atmosphere. The researchers considered both high and low estimates for this so-called fugitive methane.
The combined effect of the three the scientists found is that the global energy system could experience unprecedented changes in the growth of natural gas production
and significant changes to the types of energy used but without much reduction to projected climate change if new mitigation policies are not put in place to support the deployment of renewable energy technologies.
Abundant gas may have a lot of benefits--economic growth local air pollution energy security and so on. There's been some hope that slowing climate change could also be one of its benefits
but that turns out not to be said the case Mcjeon. Scientists engineers and economists from the following institutions contributed to the research:
Beyond improving food crops the technique could also help improve plants grown for energy production materials and other purposes.

Wildland fires involve complex interactions that include fuel distribution terrain topography chemical reactions energy transfer and the associated fluid dynamics that transport moisture gas-phase hydrocarbons air
when you see this raging fire where exactly is all this energy being released in space?
Where the energy release associated with combustion is released its intensity and how it is being released are all basics for predictive ability.
Where the energy is released is what is going to dictate the fluid dynamics in the vicinity.
Energy released by fire heats and converts heavy hydrocarbons in the materials burning into light gaseous hydrocarbons that are burned more readily.
which the energy release will drive the airflow around it and the resulting fluid dynamics will in turn drive the fire.
and it is gaining heat as energy is produced as a result of combustion so it is an energy balance problem.
We also initiated a series of studies to examine the transition between a ground fire and tree crown burning.

All of this works in ambient temperatures unlike current high-temperature capture technologies that use up a significant portion of the energy being produced.
Of those approaches none came close to reducing emissions as much as conservation increased energy efficiency and low-carbon fuels would.

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
. If changes in humidity could be harnessed to generate electricity night and day using a scaled up version of this new generator it could provide the world with a desperately needed new source of renewable energy.
