Примеры fossil fuel

• In recent times, agriculture has become a major fossil fuel energy user.

• The impression given is that fossil fuel use will continue to rise, and that coal is the fuel of the future.

• Our calculations indicate that rotation and no-till systems use substantially less fossil fuel in comparison to conventional systems.

• For each farm type (conventional, rotation and no-till) we estimated average yearly fossil fuel energy use.

• As fossil fuel reserves diminish, alternative renewable sources of energy will be needed to sustain economic growth.

• Our model of baseline fossil fuel consumption allows autonomous energy efficiency improvements.

• The model's dynamics derive from fossil fuel depletion, productive capital accumulation, and the putty/semi-putty specification of technology.

• This however will be weighed against the effect of more expensive fossil fuels, as a result of the fossil fuel tax.

• Whereas these studies have been retrospective, we use a dynamic general equilibrium model to investigate global and regional sustainability over the period 1985 - 2050, focusing on fossil fuel extraction.

• For these regions, if economic depreciation (as a proportion of the total value of fossil fuel extraction) were to exceed 67, 50 and 24 per cent respectively, would change sign.

• There is no systematic empirical evidence that highly indebted developing countries exploit more their subsoil fossil fuel and mineral resources or produce more cash crops for exports than other countries.

• The question of structural change is not really serious for those who believe that transition away from fossil fuel based energy supply will suffice to de-carbonize the economy.

• Even though it has long been known that the global inventory of fossil fuel is finite, no serious action had been taken to face this problem.

• A comparison of our cumulative emissions projections to historic emissions from fossil fuel combustion highlights the magnitude of the threat from continued global development along historical trajectories.

• Nevertheless, they will never come close to replacing all the current, fossil fuel-powered vehicles.
