What started in 1970 as a teach-in about the environment has expanded year by year until Earth Day actions this year include more than one billion people in some 192 countries.
Many people are taking photos of their climate change ...
The development of low-carbon energy is progressing too slowly to limit global warming, the International Energy Agency (IEA) said on Wednesday.
With power generation still dominated by coal and governments failing to increase investment ...
The U.S. Environmental Protection Agency has consistently over-estimated the prospects for production of advanced biofuel
s from non-food crops, adding to the impression of a biofuel
policy that is out of step with reality.
The U.S. ...
Australia's main electricity market could source all of its electricity from renewable energy with the help of a carbon price of as low as $50 a tonne, according to research at the University of NSW.
The researchers found currently ...
Researchers have taken a step closer to using atmospheric carbon dioxide as a biofuel
, potentially helping mitigate climate change while at the same time meeting rising energy demand, according to a study published in the Proceedings of the ...
Rapidly growing trees like poplars and willows are candidate "biofuel crops" from which it is expected that cellulosic ethanol and higher energy content fuels can be efficiently extracted. Domesticating these as crops requires a deep ...
Covering a global industry like automotive is air travel dependent.
I won't go into the awful details, but my annual carbon footprint is alarming. British Airways estimates in-flight carbon dioxide emission of a 10th of a kilogram per ...
Five years ago, rural America was giddy for ethanol.Backed by government subsidies and mandates, hundreds of ethanol plants
rose among the golden fields of the Corn Belt, bringing jobs and business to small towns, providing farmers with a ...
The rush around the world to plant crops used to produce biofuel
has not only sparked a global food vs. fuel debate, but it’s also putting biodiversity at risk.
Last fall, a group of more than 200 American scientists banded together to ...
Developers of second generation biofuel
s made from non-food crops and waste material are on track to deliver fuels that are cost-competitive with ethanol and conventional fossil fuels by the second half of this decade.
That is the ...
Corn based ethanol makes up 10% of the fuel mix in the US and EPA has approved a 15% mix. But last year 20 ethanol producers closed up shop. Wallace Tyner, an energy economist at Purdue University explains to host Steve Curwood why small ethanol ...
Following a promising start, Brazil`s dream of positioning ethanol in the global market on an equal standing with petroleum-based fuels is hindered by new and old challenges.
Brazil`s goal of expanding ethanol sales across the world will ...
In our ongoing quest for alternative energy sources, researchers are looking more to plants
that grow in the wild for use in biofuel
such as switchgrass.
However, attempts to "domesticate" wild-growing plants
have a downside, as ...
Corn ethanol would get a larger share of the U.S. gasoline market under a government proposal on Thursday while ranchers, environmentalists and the oil industry aim to kill the renewable fuels mandate altogether.
The Obama administration ...
Days after a federal appeals court said the Obama administration is setting overly optimistic production quotas for the struggling biofuel
s industry, the government issued new standards Thursday that raise production estimates for ...
A federal court delivered a defeat to the biofuel
s industry Friday, ruling the U.S. government exceeded its authority by requiring refiners to purchase cellulosic biofuel
despite the fact the next-generation fuel is not commercially ...
President Obama had mentioned climate change in prominent speeches before Monday.In his November victory speech, he spoke of protecting America’s children from “the destructive power of a warming planet.” At his first inauguration, he ...
On Jan. 11, the National Climate Assessment Advisory Committee — a consortium of 13 federal agencies — released its third draft report on the impact of climate change on the U.S. As seems to be the rule with federal documents, it’s monstrously ...
A mix of perennial grasses and herbs might offer the best chance for the U.S. to produce a sustainable biofuel
, according to the results of a new study. But making that dream a reality could harm local environments and would require developing ...
Water resources, energy and land use are so mutually dependent that climate-related disruptions to any one of them could lead to economically devastating ripple effects -- especially as a growing population puts increasing strains on all three. ...

Some Canadian renewable energy companies with activities in the United States will be among those benefiting from U.S. "fiscal cliff" legislation that extended crucial tax credits for wind energy and biodiesel production.
As well as ...
Green schemes to fight climate change by producing more bio-fuels could actually worsen a little-known type of air pollution and cause almost 1,400 premature deaths a year in Europe by 2020, a study showed on Sunday.
The report said ...
WHETHER streaming from the tailpipes of cars or the smokestacks of so many power plants
and factories, carbon dioxide emissions keep growing around the globe.Now a Canadian company has developed a cleansing technology that may one day ...
