Unlike conventional aircraft which burn kerosene oe a polluting fossil fuel-Leslie's plane was powered by fuel derived from rapeseed oil.
These kinds of fuels are considered to be eco-friendly and"green  because the plants from
For example, newly released figures collected by a plane trailing the Canadian Falcon 20 suggested that there was a 50%reduction in aerosol emissions compared to conventional fuel.
Previous studies with the rapeseed fuel also show that there is a 25%reduction in particles

 In 2008, Virgin Atlantic was the first to fly a plane on a blend of biofuel and regular jet fuel.

But you would be wrong. Sound barrierbiofuels are not without problems leading the chief scientist of environmental group Greenpeace to label the first flight by Virgin as high-altitude greenwash.
which cautioned that the entire life cycle of a fuel has to be assessed before it can be called Ëoegreen'.
'The 2011 analysis of 14 fuel sources, including conventional petroleum-based jet fuel, showed that emissions from burning biofuels varied hugely depending on the type of land used to grow the fuel-crops.
For example, biofuels made with palm oil from a plantation made by clearing rainforest emitted 55 times more carbon dioxide (over its life cycle) than oil from a previously cleared area.
The comparison with conventional fuels can look very different too. Crops grown in an unsustainable manner can actually create fuels that emit 10 times more CO2 than fossil-fuel based fuel."
"The situation is more complex than just looking to biofuels, Â says Prof Barrett.""There are many types of biofuel,
Â"We really do believe that by 2030,30%of all airplane fuel could be provided by sustainable biofuels.

humans have been burning increasing amounts of fossil fuels, releasing stored carbon from millions of years ago.
Even if we stopped burning fossil fuels today, there is enough carbon dioxide in the atmosphere -and it is such a persistent,
so that the greenhouse gas produced during fossil fuel burning can be removed from the exhaust emissions. The carbon dioxide can then be cooled
Another storage option is to use the collected gas to replace crude oil deposits, helping drilling companies to pump out oil from hard to reach places, in a process known as advanced oil recovery.
and storage oe is a useful way of preventing additional carbon dioxide from entering the atmosphere as we continue to burn fossil fuels.
there isn't enough space to store it securely in saline aquifers or oil wells. But geologists are coming up with alternatives.
His idea is to use the carbon dioxide to make liquid fuels for transport vehicles. Carbon dioxide can react with water to produce carbon monoxide
and hydrogen oe a combination known as syngas because it can be turned readily into hydrocarbon fuels such as methanol or diesel.
The Haber reaction requires burning fossil fuels which emit carbon dioxide. And other potent greenhouse gases, including nitrous oxide,
but it uses valuable animal fodder or cooking fuel. As with all fertilisers, manure runoff can also pollute rivers and oceans with eutrophication (death by oxygen starvation.
and the cost of transportation is very high on the continent because of high fuel prices and terrible roads.

And the fuels used by each of us for energy have produced combined emissions that are already altering the planet's climate.
By 2050, it is estimated that we could triple our resource consumption to a whopping 140 billion tonnes of minerals, ores, fossil fuels and biomass per year.
Technology and innovation has saved already us from plagues, low crop yields, water shortages, reliance on fossil fuels and more.
so charcoal is added to keep the tobacco burning. Â This means the smoke inhaled derives from charcoal too
and charcoal contains several toxic substances, including carbon monoxide, heavy metals and tar. Some water-pipes are sold with mouthpieces containing cotton filters or a plastic mesh.
This does result in smaller bubbles, but a report by the World Health Organisation says there is no evidence that these mouthpieces reduce the harm.

We were even able to improve on our external sources of energy by expanding our range of fuels:
rather than relying on what fuel grew in forests and the continual recycling of biomatter,
we delved deep into the ground to extract fossil fuels made over geological timescales. Humans proved so clever and successful that we were able to overcome almost all the environmental limitations that restricted other species to their ecological niches.

there is room for all fuels, and all are needed to produce alternatives to fossil fuels. The challenge today is to increase the amount of sustainable biofuels in themselves

and has analyzed its environmental impact, both in relation to each other and as alternatives to fossil fuels such as petrol and diesel.
Biogas performed 140 percent better than gasoline and diesel and had a net carbon benefit.
However, even the weakest-performing alternative still attained twice the EU standard that biofuels reduce greenhouse gases by at least 35 percent compared with fossil fuels.
