„We are approaching the point where the energy consumption for exploration and transportationoutside the Middle East is higher than the energy which is extracted from it. Our national economiesshould be steered by energy balances and not mainlythrough monetary dimensions. Money is relative and transient, but energy is essential and eternal. Weshould realise that problems of energy, environment, climate and development are interconnected“.
Alexander King, Former President
of the Club of Rome (1985)

„We need to conserve some of the fossil fuelresources for the future and createadequate substitutes in quantities whichcould meet the requirements of the people and enable future development.“ „ ... everyeffort should be made to develop thepotential for renewable energy which shouldfrom the foundation of the global energy structure during the 21st century.“

Fuels derived from biomass are not only potentiallyrenewable, but are also sufficiently similar in originto be the fossil fuels to provide direct substitution. They can be converted into a wide variety of energy carriers as of recent through conversiontechnologies, and thus have the potential to besignificant new sources of energy into the 21st
century.
The input/output energy balance ratio may reach up to 1:25. The CO2 mitigation potential of energy cropsas energy sources is considerably large.

Global Global BiomassBiomass and and PerspectivesPerspectives
• Annual primary biomass production: 220 billions DM, 4,500 EJ = 10 times of world primary energy consumption.
Biomass used for food: 800 millions DM = 0.4% of primary biomass production.
• Annual food production corresponds to 140% of theneeds of world population.
• Biomass currently supplies 14% of the worldwideenergy consumption. The level varies from 90% in countries such Nepal, 45% in India, 28% in China and Brazil with conversion efficiency of less than10%. The potential of improving this effiencythrough novel technologies is very high.
• Large areas of surplus of agricultural in USA, EU, East Europe and former soviet countries and couldbecome significant biomas producing areas (> 200 millions ha).

• Microalgae have the potential to achieve a greater levelof photosynthetic effiency than most other forms of plant life. If laboratory production can be effectivelyscaled up to commercial quantities levels of up to 200 mt/ha/yr may be obtained.
• The efficiency of photosythetic is less than 1%. An increase in this efficiency (through genetic engineering) would have spectacular effects in biomass productivity: successful transformation of C4-mechanism (frommaize) to C3-crops (rice). New achievement in accelarating cell division opens opportunities to speedup the growing seasons, resulting in several harvestsper year and an overall increase in biomass.
• Developments in car technologies is leading to significant reduction in fuel consumption, i.e. less areaswill be needed for more cars.
