We can use ethanol, biodiesel and methane to run our vehicles equally well or better.
And methane can be made from any type of biomass at all, including sewage and landfills.
The most important of these in terms of their global contribution to climate change are carbon dioxide and methane.
This is because methane from clathrates and methane from peat are slightly different.
The hydrothermal vents, cold seeps and methane vents we shall shortly discover are all ecosystems which depend on chemical energy.
Basic chemistry predicts that ammonia and methane should naturally coexist in varying quantities unless they are in extremely cold or hot environments.
FORBES: Astronomers Conduct 'Reconnaissance' Of Another Solar System
OK, things like carbon dioxide and methane are invisible, but still.
This gas contains approximately 80% of the original energy content of the coal, and is a combination of hydrogen, carbon monoxide, carbon dioxide, and methane.
FORBES: Underground Coal Gasification: A Trend Worth Watching
Enterprises are being pressed to change over from coal to cleaner-burning natural gas and methane, and to be more energy-efficient by modernizing their plant equipment in the switch.
The idea that the climate has been changing because of human behavior, including the release of greenhouse gases like carbon dioxide and methane, is widely accepted by scientists.
FORBES: Michael Bloomberg Endorses Barack Obama Because Of Climate Change
Siemens and Shell, for example, have just announced a new fuel-cell technology for oil rigs that will capture emissions of carbon dioxide and methane, generate power from them cleanly, and sequester the exhaust.
Because scientists who study climate agree that it is being modified by the human release of greenhouse gasses like carbon dioxide and methane and that this puts places like New York City at risk.
FORBES: What If Mike Bloomberg Is Right And A Climate Change Nightmare Is Here?
That tillage would release carbon dioxide and methane.
ECONOMIST: Biochar could enrich soils and cut greenhouse gases as well
Earlier this month, scientists at Duke University published a paper in the Proceedings of the National Academies that provided evidence of a link between shale-gas wells and methane contamination in nearby drinking water supplied.
Those estimates are based on full fuel-cycles, combine all steps in the use of a fuel from production to consumption, and include carbon dioxide, nitrous oxide and methane, the three major greenhouse gases emitted by motor vehicles.
In order for M. smithii to thrive, it needs the hydrogen from surrounding microbes, and that may be why people with higher levels of both hydrogen and methane gases in their breath were heavier than those with elevated levels of methane or hydrogen alone.
One theory is that an initial warming changed the distribution of heat in the oceans so that deposits of gas hydrates on the sea floor were released, with carbon dioxide and methane rising to the surface and entering the atmosphere, causing further greenhouse warming.

And, methane can be made cheaply and easily from any type of biomass at all, including sewage and landfills.
Microturbines can run on natural gas as well as other fuels, including kerosene and the methane given off by landfills and sewage-treatment plants.
We have extensive experience and infrastructure for methane, and it can do anything we need done.
First, the hog waste is placed in an anaerobic digester, which contains bacteria that consume the manure and release methane gas.
Outside the U.S., capturing and trading methane is already a great market.
California regulators have approved four categories of carbon offsets in its soon-to-launch cap-and-trade program: forestry, urban forestry, ozone depleting substances, and agricultural methane.
In other words, the extraction process, if done improperly, could cause sudden disruptions on the ocean floor, reducing ocean pressure rates and releasing methane gas from hydrates.
But today Professor Andy Cooper and his team of chemists at the University of Liverpool in England are figuring out how it can help energy companies like BP or Shell store and transport methane gas, the principle component of natural gas.
The rest amounted to little more than extensions and expansions of current policy that would have to be approved by Congress, including doubling the tax credit for producers who make electricity from wind, biomass and landfill methane, the Gore campaign said.
But critics of shale gas point to environmental concerns such as high water use and possible water contamination, the release of methane and, to a lesser extent, earth tremors caused by drilling.
Opponents warn that fracking is an environmental disaster waiting to happen, citing, among other risks, air and water pollution, the release of radiation and cancer-causing substances, and the acceleration of global climate change as methane and other greenhouse gases escape during fracking.
The oil and gas industry has said the EPA has overestimated emissions of methane and argued that they already were working to reduce pollution, without the agency's intervention.
