In the context of the current sharp rise in energy prices and climate changes, humankind faces two major problems: food provision and energy shortages. The Republic of Moldova possess few energy resources, so being forced to importnear 95%, energy crops cultivation seems to offer an ideal solution to the problem of alternative energy sources.The investigation of introduced tall perennial grasses for biofuel production is an important object in Botanical Garden (Institute) of ASM. Agro biological peculiarities introduced plant species provide perspectives for cultivation in theRepublic of Moldova: Macleaya cordata, Sorghum almum, Sida hermaphrodita, Helianthus tuberosus, Miscanthus xgiganteus, Symphyotrichum novi-belgii with 10-20 years longevity. Cultivation and harvesting of these species do notneed sophisticated mechanisms and specific equipment as in forest exploitations, ensuring a high quantity of drybiomass: 11.0-27.2 t / year / ha with gross calorific value – 18.5 to 20.0 MJ / kg. Biomass potential of these species canbe developed in three main directions for biofuel production briquettes or pellets, bio-ethanol, biogas being transformed into energy.
