It's been a while since a good poo-power story has come down the pipe, but here's an interesting one: Massachusetts-based biofuels company Qteros and wastewater recyclers Applied Clean Tech have announced that they

Can we just all put palm oil biodiesel produced on deforested peatlands to rest already: A new report from the United Nations Environment Programme shows that biodiesel production under these

New Environmental Protection Agency requirements for its Renewable Fuel Standards program have been released which raise an issue which has sat dormant for a little while: How to calculate the greenhouse gas emissions of a

This week USEPA announced that the maximum ethanol content of motor fuel sold in the USA would be allowed to rise from 10% to 15%. Positives of the Agency's decision are: reduced dependence on foreign

The first large-scale commercial operation to produce cellulosic ethanol (the kind of ethanol made not from corn or other grown crops, but from organic waste) in the US just got major backing from the oil industry, and will be online in 2013. The New

Germans rate respect for having a national identity as eco-conscious people. Should it therefore come as a surprise that Germans are not embracing the advent of E10, a 10% ethanol-gasoline mixture, which has

Photo: Stephanie Says, Flickr, CC Turning Food into Fuel is Not the Solution The Association of American Physicians and Surgeons (AAPS) has released a warning that U.S. and European policy to increase the production of biofuels could lead to almost

Is the conventional wisdom that we need not worry about tailpipe emissions in biofuel-powered vehicles, because the plants had been absorbing carbon while growing, grossly misguided?

The massive diversion of grain to fuel cars has helped drive up food prices, leaving low-income consumers everywhere to suffer some of the most severe food price inflation in history.

An ethanol production mandate could be in conflict with efforts to reduce the Gulf Coast dead zone.

Could this be the lawnmower we've all been waiting for?

Big Auto is increasingly coming up against Big Tech.

Great cities know the future is renewable.

And we thought it was all about symbolism...

"Being the Change" is proof that weaning oneself off fossil fuels is not only possible, but also joyful and fun for a young suburban family.

Ed. note: This post, about ethanol is now the third post (read about biodiesel and compost to catch up) in the Green Basics series of posts that TreeHugger is writing to provide basic information about important ideas, materials and technologies for new

A level playing field for renewables is about to get a step closer, at least in Morocco.

The researchers have found a simple way to create an energy source for fuel cells using CO2 in the air.

The country's onward march of low carbon energy shows no signs of stopping.

It's hard to imagine that the widespread issue of electronic waste could be seen as anything more than a problem, but what if it could be reused to make homegrown algae biofuels? That's what industrial design students at of the

When you think Mexico, think biofuels (not just tequila). That's the message of OriginOil, a Los Angeles, California, company that's been contracted by the Mexican government to produce 1 percent of the

We really do need more of this kind of thinking.

Is this company getting closer to the dream of making truly sustainable carbon-negative fuel?

Tipster Peter S. was equally bemused by our mention of the petroleum powered bicycle jetpack. So much so, he thought one good turn deserved another. Thus we’ve now discovered the MobiBke. Take one foldable full performance Dahon ZeroG mountain bike

Thanks to COVID-19, a lot more than previously thought.

Although somewhat symbolic, the new legislation coincides with the 2040 end of gas and diesel vehicle sales.

The aquarium and wildlife rescue center uses a unique heat pump system to cover 98% of its heating needs.

Prices have fallen 12% thanks to this switch to renewables.

Once you have paid for the panels or turbines, renewable power is almost free.

70% of this potent pollutant comes from fossil fuels, not biomass burning.

There are a lot of good ideas in this truck; will they catch on?

Solar power has grown up, and it's ready to blow up.

More on why our personal consumption habits matter in the climate emergency.

Simply by telling pilots their fuel consumption is being monitored, Virgin Atlantic saved millions.

This is not a joke. It is also a teaching moment about blogging.

They say it reduces CO2 emissions by 80 percent. Does it really?

When you buy a burger, it could be from a cow raised on Brazilian soy feed. That's a problem.

A newly developed, solar powered “leaf” mimics photosynthesis, converting CO2 into fuel.

It turns out that it's probably beef fat.

Buell motorcycles are fast, beautiful and expensive. How does Erik Buell's e-bike compare?

As alternatives to Big Oil and Big Coal emerge, it would be a mistake for executives to rely on loyalty or love from the public.

Anti-greens often try to make economic arguments against the big spring-cleaning that our civilization is going through.

Fossil fuel company executives and D.C. politicians have long worked together to ensure coal and oil prices stay low enough to keep Americans hooked. Here's how we can break the addiction.

Forget about Tony Stark or the Bionic Man, the real cyborg action starts with microscopic swamp creatures

Not by a long shot, but the answer is still interesting.
