Natural gas, which is mainly methane, may generate less carbon dioxide than oil and coal when burned, but as recent research has found, there's more to greenhouse gas emissions than just combustion.

Natural gas is a fossil fuel — like oil and coal — and it does produce carbon dioxide as a result of the combustion process.

In addition, the brand will remain committed to vehicles powered with compressed natural gas (CNG) as well as internal combustion engines.

Natural gas is widely considered to be an environmentally cleaner fuel than coal because it does not produce detrimental by - products such as sulfur, mercury, ash and particulates and because it provides twice the energy per unit of weight with half the carbon footprint during combustion.

The NRDC cites the «2016 State of the Market» report by PJM, the largest grid operator in North America, as showing that «new entrant natural gas - fired combined cycle plants, combustion turbine plants, and solar are economical, but that new coal and nuclear plants are not.»

I think you'd be much better off just drying and pelletizing the cellulosic material and using a syngas generator to produce carbon monoxide and then fuel your internal combustion engine directly from the CO which requires very little modification to the engine — about the same as the modifications required to run it from natural gas or propane.

Methane emissions derive mostly from landfills, agriculture (particularly rice farming), livestock, and natural gas and coal extraction, while soot, otherwise called «black carbon», results from the incomplete combustion of fossil fuels and derives primarily from primitive cook stoves used throughout much of the developing world, as well as diesel engines and coal - burning power plants.

Carbon combustion generated 80 % of someone's energy, but it sure as heck doesn't constitute much of the energy of people who can take advantage of cheaper geothermal, hydro or natural gas (which is largely hydrogen combustion); and as the price of solar and wind plummet and the practicality of extracting fossil other than gas drops like a stone in lock step with the advances of competing technologies, what sort of backwards knuckle - dragger actually wants the choking and fumes and leaks and inconvenience and dust and soot and sulfates?

Although a fossil fuel, combustion of natural gas emits only 45 % as much carbon dioxide as combustion of coal, and hydroelectric is of course a very low - carbon energy source.

That has come courtesy of its association with conventional natural gas - which produces much less CO2 on combustion than coal and oil, and which is often touted as a «clean» fuel.

At the heart of both studies is a deeper concern about the response of the natural world to human - induced change, in the destruction of habitat, the loss of the plants, birds, insects, mammals, amphibians and reptiles that depend on habitat, and in the steady increase in atmospheric levels of greenhouse gases, as a consequence of profligate combustion of fossil fuels.

Research such as this is vital because, although the most visible attempts to reduce global warming and mitigate climate change depend on lowering greenhouse gas emissions from fossil fuel combustion, there is another, parallel, approach: to limit the emissions that spring from land use change, chiefly by preserving natural forests.

Depending on the electricity source of the local grid, even the most efficient electric car could be charged by coal or natural gas, or by hydropower (no combustion emissions, but linked to increased methane emissions), or nuclear energy (which might qualify as clean or low - carbon energy, but which also has its own environmental bugaboos and massive costs to consider)

1Coal combustion emits almost twice as much carbon dioxide per unit of energy as does the combustion of natural gas, whereas the amount from crude oil combustion falls between coal and natural gas, according to Energy Information Administration, Emissions of Greenhouse Gases in the United States 1985 - 1990, DOE / EIA -0573 (Washington, DC, September 1993), p. 16.
