The criteria were determined as the potential profit rate per unit of time, the compatibility of potential order with the available capacity, the level of potential future order with higher profit, customer credit of future business opportunity, and the negotiability level of production schedule for the order.
A major benefit of 2G biofuels is considered to be their potential to deliver very significant life cycle GHG emission reductions compared with fossil fuels (other benefits include minimisation of conflict with food crop production, capacity to use poorer marginal land, high yields of biomass per unit of land, diversity of potential feedstocks).
But if you want to make methane leakage sound scarier than it really is, you can present the short term GWPw (global warming potential per unit of weight) of 25 or 72, rather than the long term GWPfm of 3.3 or 10, and perhaps hope that the reader will do the mistaken calculation and come away overly frightened by the large value.
Compared with other low carbon power sources, wind turbines have some of the lowest global warming potential per unit of electrical energy generated.
The TEV of an ecosystem in providing biological products for an economy is determined by multiplying a money-to-energy conversion factor (measured in a monetary value per unit of energy) by the energy potential of the ecosystem.
The survivor function is the probability that a person survives longer than some specified time t without taking up a modern contraceptive, while the hazard function gives the instantaneous potential per unit of time for use of a modern contraceptive to be started, given that the individual modern contraceptive uptake time survived up to time t.
To meet future needs for biomass, not only for energy, also for food, feed and materials emphasis must be put on increasing the production of biomass per unit of land and exploring the potentials in new biomass sources to reduce the pressure on native and protected eco systems.
The difference is that trees are half water by weight, which means there's less potential energy per unit of carbon emissions in biomass energy than in fossil fuels like coal.
Potential and specific EEA (per unit of Cmic) increased from macro- to microaggregates.
This indicates the massive potential reduction in methane production per unit of liveweight gain that can result from supplementation (Leng, 1989).
