Mascoma Corp. says it has found a way to remove several steps from the process of making cellulosic ethanol, cutting the cost and time it takes to make the fuel, while increasing yields.

The Lebanon, N.H.-based company says it has made advances in consolidated bioprocessing, a process that uses engineered microorganism to make ethanol from cellulosic biomass, such as grasses, stalks and wood waste. Mascoma’s CBP process eliminates the need to produce costly cellulase enzymes, by producing the cellulase and ethanol in a single step.

Florida authorities have announced bold plans to begin running many of the state’s trains on biodiesel. The switch will result in a significant reduction in carbon emissons and drastically reduce the chances of soil pollution in the event of a fuel spill.

Under the plan, South Florida’s Tri-Rail system is to operate 8 of its fleet of 10 locomotives on a 99 per cent blend of either soya or palm oil. The move has been hailed as an important step towards energy independence by the nation’s top transport regulator, the Federal Transit Administration.

Pacific Gas and Electric in California announced last week it will buy 800 megawatts of solar-generated electricity from two companies, enough to light 239,000 homes. Within three years, PG&E will buy its solar energy from OptiSolar and SunPower, which plan to build the world’s two largest solar farms in California as part of the deal.

It would nearly double the USA’s entire solar-panel capacity. Driving the trend are solar’s falling costs and state alternative-energy mandates.

Solar power has grown but still makes up well under 1% of U.S. power generation. More than 90% of solar panels have been installed on rooftops by maverick consumers and businesses. Utilities’ embrace of solar energy will help push it to about 10% of power generation by 2025, predicts Ron Pernick, principal of research firm Clean Edge.

“Just a handful of utilities doing something big changes the scale of the entire market,” says Julia Hamm of the Solar Electric Power Association.

Solar energy refers to the utilization of the radiant energy from the Sun. Solar power is used interchangeably with solar energy, but refers more specifically to the conversion of sunlight into electricity, either by photovoltaics and concentrating solar thermal devices, or by one of several experimental technologies such as thermoelectric converters, solar chimneys or solar ponds.

You Might Be Very Surprised

A few days back I posted a You Tube presentation about two professors from Duke University who came up with a different, and in their minds, more accurate way to determine the efficiency of the engine in your vehicle.

It’s nice to know how many miles per gallon (MPG), or as the profs say, gallons per mile (GPM) your vehicle will get, but there’s more, much more to that equation.

First of all, you’re paying a premium for regular gasoline, $4 maybe in excess of $5 a gallon, and you decide to fill it up.  Sticker shock will settle in quickly, but how about this, how many hours will you have to work in order to pay for that fuel?

Citing green hotels, coconut oil fuel for airlines and even recyclable golf tees, executives in one of the world’s largest industries say they are urgently trying to shrink tourism’s oversized environmental footprint.

But with global travel projected to keep soaring, and those very leaders still eager to expand their own ventures, some doubt such efforts can significantly lessen global warming and other ecological woes.

“There are no simple solutions,” Anna Pollack, head of a British tourism consultancy, told a two-day conference which ended Wednesday. “Tourism is both a victim of and a contributor to climate change.”

Online you can read the a lot guides about how to reduce global warming. As you can see travel is only a little part of the main causes of global warming.

Below, I list of useful guides. You can use to reduce global warming.

Global warming refers to the Earth’s air and oceans gradually heating up to a point that disrupts balance, a problem that is continually getting worse. It sounds like a problem too massive for any one individual to take on, but it really isn’t. Combining any few of these suggestions can make more of a dramatic effect than most people understand. The goal is to emit less carbon dioxide into the atmospher

The part of Global warming caused by travel, is especially the ecotourism, practiced in remote destination. It’s so because it requires the use of air travel to land is those countries.

Some times ago an airline company used to travel with biofuel.

IN February, on a chilly, clear Sunday morning, Sir Richard Branson, president of Virgin Atlantic, along with the co-sponsors Boeing and GE Aviation, lured more than 200 journalists to a hangar at Heathrow Airport near London to witness what they said was airline history. Over flutes of Champagne and plates of mini-bagels filled with salmon, everyone’s eyes were fixed on a 747 as it took off on the world’s first biofuel demonstration flight.

Never mind that only one of the plane’s engines used biofuel, and that was about 25 percent mixed with standard kerosene jet fuel. It was still significant, given that air travel is the fastest-growing source of global greenhouse gases, and the race to find an alternative to kerosene is now crucial. The biofuel used — a combination of coconut and babassu (a Brazilian tree) oil, which Mr. Branson pretended to drink that day like an island cocktail from a coconut shell — worked in this very small test. But even its developers, Imperium Renewables, are aware it could never become a substitute for what John Plaza, president and chief executive of Imperium, another sponsor, says is the 87 billion gallons of fuel needed each year to fly the world’s airline fleet.

“This is just a first-generation product,” Mr. Plaza said. “But the test was meaningful in that it showed that a biofuel was viable with the infrastructure in a commercial jet.” Imperium created the fuel from oils harvested from existing plantations, but Mr. Plaza said he believed that algae was the fuel of the future. “You would only need the landmass of West Virginia,” he said, “to make enough fuel to replace aviation’s demand for kerosene.”

So I’m not scared about the future, because change is happened. I think that most airlines will become more green so traveling in foreign countries will be less environmental damaging.

Those cute little creatures shown in the video are represent what may be the future of carbon sequestration.

CARS is the acronym for Carbon Algae Recycling System, it’s a system under development in Canada to clean up tailing ponds and greenhouse gas emissions left by the Alberta Tar Sands project.

As the video shows, exhaust CO2 is pumped into algae-rich tailing ponds where it’s digested. The plumped-out algae, full of hydrocarbons and heavy metals, are harvested and turned into biofuels.
