Sentences with phrase «fuel crops like»

These «second - generation» bioenergy crops are often seen as the future of bioenergy because, as perennials, they are far better at storing carbon in the soil and in their biomass than traditional fuel crops like corn and canola.

Not exact matches

But increasingly farmers also sell biomass — the residue left over after crops like corn and wheat are harvested — to companies developing fuel from organic material.

Nearly half the world's population rely on solid fuels like wood and crop residue to cook.

The fiber and fuel derived from hemp would be carbon neutral and as such wouldn't contribute to global warming — and in fact could help mitigate rising temperatures by replacing chemical - intensive crops like cotton and imported fossil fuels like oil and gas.

Like bankers do for financial debt, climate scientists assume that the greenhouse gas expense of burning biofuels will be paid back eventually as the crops that make fuel «earn» carbon through sequestering it throughout their life cycle.

But the problem is that most of the ethanol we have right now is when it is talked about it being a first generation biofuel; that is that ethanol fuel is coming from the fermentation of sugars from crops like corn.

AltAir does better by sourcing its bio — jet fuel from oil seed — bearing plants, like camelina, but that limits the amount that can be planted in rotation with food crops like wheat given constraints on the amount of land available for the latter.

Instead of processing commodities that might otherwise be used for food, next generation fuels can be produced from dedicated energy crops like switchgrass, to the non-edible parts of corn plants, to unmarketable wood from the lumber industry — taking resources that would otherwise go to waste and using them to fuel our energy independence.

Other biomass - based fuels, however, are genuinely sustainable — fuels derived from things like crop waste, or switchgrass, or sustainably harvested cover crops.

The current crop of hybrids includes cars like this Accord, the Chevy Malibu, the Hyundai Sonata, etc., that, while not returning Prius - like economy numbers, also look and drive more or less like conventional fuel - burning cars.

A better title would have been: «Fueled: The Effects of Using Food for Fuel» or something like that, because the central question of the book is to what degree has using crops to produce biomass for fuel production (usually ethanol) affected the costs of food and fFuel» or something like that, because the central question of the book is to what degree has using crops to produce biomass for fuel production (usually ethanol) affected the costs of food and ffuel production (usually ethanol) affected the costs of food and fuelfuel.

Rich sees the technology that converts perennial crops like Miscanthus into low - carbon fuels as a science that could «change the world,» and is understandably excited at the prospects of utilizing non-food based biofuels as one solution to oil use.

Ethanol is an alcohol - based alternative fuel made through a distillation and fermentation process using plant crops, like corn.

Another critic argues that the studies fail to consider no - till cultivation of biofuel crops, which actually increase soil carbon storage, and that corn ethanol plants are converting to renewable energy, thus decreasing their emissions - meanwhile they are competing against fossil fuels like oil from tar sands that have an increased carbon footprint even compared to conventional gasoline.

Biofuels also are contributing to the hikes but mainly because the EU and the United States are subsidizing domestic production of crops like corn that offer low efficiency when turned into fuel and compete with other foodstuffs for large swathes of land in these already densely populated areas, Clini said.

In other words, cellulosic conversion technology could easily drive deforestation, especially in the tropics where converting natural systems to fuel would be easier than planting potential fuel - crops like oil palm, sugar cane, soybeans, or corn.
