fuel storage pool for at least 72 hrs (an extra inventory of about 800 m3).
The fee for unconventional fossil
fuels, such as oil from tar sands and gas from hydrofracking, should

We will need to wait until the 16 academic - lead studies are completed to compare them with the national top - down emissions rate reported by Miller et al. for fossil
fuel related emissions,
including end uses and natural
leakage, neither of which is being measured in these studies.
Typical examples
include: the expectation of high return on investment (short payback period); high capital costs and long project development times for some measures; lack of access to capital for energy efficiency improvements and feedstock /
fuel change; fair market value for cogenerated electricity to the grid; and costs / lack of awareness of need for control of HFC
leakage.
