Scientists: Biofuel is more harmful then oil and gas
Biofuel and a number of other renewed energy sources which should replace oil and natural gas, cause more significant greenhouse effect, than the last.
Such information was published by London The Times referring to the newest researches of the British scientists.
Group of experts from Edinburgh University have established that emissions from combustion of the biofuel made of corn or rape seeds are more destructive for an atmosphere of the Earth, than emissions from combustion of similar quantity of oil and gas.
In result biofuel creates from 50 up to 70 % more greenhouse gases, than traditional fuel, that lead to warming-up of the planet’s climate.
The leading countries have recently accepted arrogant programs to replace oil and natural gas with the alternative energy sources, and first with biofuel. In the EU 80 % of all biofuel is made from rape.

It’s interesting and important to note that some groups are taking the bio-fuel downside seriously. The negative energy balance in most bio-fuel production also challenges widespread use of bio-fuels. However, agriculture has an important energy transition role to play.
Agriculture’s most significant role in the transition from depletable to renewable fuels lies in its waste stream. Hydrocarbons in agricultural wastes provide a volumonous source of hydrogen and carbon. In the US alone annual concentated animal waste from agricluture could cover an area of roughly 1000 square miles to a depth of roughly one foot. About 18% of this waste could be converted to hydrogen and much of the rest could be used to sequester carbon in new, light weight, long lasting materials that would further advance sustainability and provide a positive net energy and greenhouse gas production balance.
With today’s technology hydrogen fuels and new light weight carbon composite materials, materials that are several times stronger than steel and and twice as light as aluminium, can be produced from these waste materials with a negative net greenhouse gas production. The same is true for the hydrocarbons in municipal waste streams.
These hydrocarbon resources are abundant, can be harvested economically, and do not deplete so long as humans continue to eat and produce waste.
When hydogen burns it burns clean therby improving air quality. In internal combustion engines burning hydrogen actually cleans the air as the engine operates. The technology to make this tansition is here and now; government, industrial and financial sector policies are not. We have to change the latter –Now!
