Clean Burning Natural Gas Vehicles (NGVs) are hot commodities in some parts of the country, where fuel can sell for as low as $0.63 per gallon.

Unlike the world’s most fuel efficient car (VW’s 285 MPG bullet), the Honda Civic GX looks like a standard passenger vehicle. What makes it special is what you don’t see: tailpipe emissions that are often cleaner than ambient air.

The Civic GX is powered by compressed natural gas—methane—the simplest and cleanest-burning hydrocarbon available. With an economical 113-hp, 1.8-Liter engine, the EPA has called the Civic the “world’s cleanest internal-combustion vehicle” with 90% cleaner emissions than the average gasoline-powered car on the road in 2004.

And get this: in Utah, natural gas can be purchased for $0.63 per gallon.

Yabba dabba doo! Thanks, as always, to Brad and Peter for allowing us to republish “Shades of Green.” You can find more of their work at The Green House. And, of course, there’s always more on alternative transportation at Gas 2.0.

Electric and hybrid electric car manufacturer Aptera has been turning heads since the first announced their space-age looking Typ1 prototype. The sub $30,000 electric version of the Typ1 has a range of 120 miles and is expected to be ready for limited release later this year.

Take a look at the latest video from Aptera, a guided tour of their factory:

As has happened before, with gas prices continuing to climb, the demand for improved fuel economy will increase as well, and all manner of improvements and upgrades that promise to help get better mileage will be touted. Some offer real benefits; others are pure snake oil.

An improvement that offers both improved mileage and increased horsepower seems counterintuitive at first. After all, the tradeoff that hybrids and other economy vehicles offer seem to be one of reduced horsepower and acceleration in exchange for improved fuel economy. So how can you have both?

General Motors announced today it would be entering into a strategic relationship with Mascoma Corp., a second-generation biofuel company with the technology to produce cellulosic ethanol from non-food sources via a single-step biochemical conversion.

The undisclosed equity share aims to contribute to joint research and development along with technology exchange, plant siting, and rapid commercialization of cellulosic ethanol technology and infrastructure. This is GM’s second investment in a cellulosic ethanol company, after announcing partnership with Coskata back in January.

As the automakers scramble to make plans for achieving 35 MPG by 2020, it seems that our suspicions that the task is entirely possible without fancy hybrids or hydrogen cars has been confirmed. The manufacturers been achieving high mileage in Europe and Japan for years now, so I expect to see it in the US eventually. Luckily, there are six exciting new technologies that are going to make it possible in the US.

These technologies are interesting because they come without the paradigm shift that seems to accompany buying a hybrid or a small economy car. Cars equipped with this green tech will be just like any other car, just more efficient.

More on the six new engine technologies after the break.

While the national average price of gasoline is now $3.60, some residents of Utah are happily filling up on compressed natural gas (CNG) at $0.63 per gallon. That’s the country’s lowest price for CNG, which has understandably caused a surge in demand for vehicles running on a fuel that one man described as “practically free.”

So far, CNG vehicles haven’t made a blip on my radar screen, even though the group Natural Gas Vehicles for America (NGVA) estimates there are 150,000 NGVs on U.S. roads today and over 5 million worldwide. It took a phone call from sunny Southern Utah to clue me in to recent developments, which include a local refueling station overflowing with CNG-hungry vehicles.

It had to happen, just when we were beginning to think that plug-in hybrid and electric cars were the best things since sliced bread, someone has intimated that there may be a health risk involved in driving those vehicles.

You remember, the power line scare back in the ’70’s (which really hasn’t gone away) and of course the more recent flap about cell phones emitting dangerous electromagnetic fields to the brain. In case you want to read more on these issues, a specific Google entry should suffice.Now, before you go somewhere else, hang on, there’s more to this electromagnetic field issue than you may think. That’s coming up, along with a short tip of the hat to the man who got us started on our way to the world we live in.

As Benjamin reported on EcoGeek last week, even if all plug-in hybrid electric vehicles (PHEVs) were recharged by coal-based electricity, they would still be an improvement over regular cars. Take a look at this graph from Technology Review, who reported that “plug-ins always result in lower emissions than conventional cars.” They beat hybrids too, unless power is coming exclusively from coal:

By many standards the UK Government is among the eco leaders of the world, with a clear commitment to make significant cuts in greenhouse emissions, numerous tax incentives for green behaviour, and longer term ambitions to reduce CO2 output by up to 80%.

However, actions speak louder than words, particularly the words of politicians.

When the British Government announced their most recent budget earlier this year, there was much applause from green groups after chancellor Alistair Darling announced almost draconian increases in taxation on gas guzzling cars.

But how effective are these taxes? Do we have a clear set of policies that are making a real difference, or is there some truth in accusations that governments are using a green agenda to raise additional tax revenue?

Working the land the natural way: Organic farming in China

It’s been almost four years since the project was launched, and of the nine households who have tried organic farming, only four are still at it. The others decided it just wasn’t worth it. Organic farming requires much more labor, the yield can be half or less of that of conventional farming, and besides, hardly anyone in Chengdu is eating organic. Our stock broker-turned-farmer estimates their customer base to be only 0.01% of Chengdu’s population.

Anlong farmer Gao Shengjian believes there’s a link between the use of pesticides and fertilizers on farms and the growing incidences of various diseases among the rural population.

China down to 12 days worth of coal

China only has enough coal for 12 days of consumption, three days less than a month ago, state media reported Wednesday, sounding the alarm bells over the nation’s most important source of energy.
