is already being replaced by alternative fuels in most uses of the fuel.

is now in shortage and will not supply global needs in the near future.

has already been substituted by alternative energy fuel resources worldwide.

has been misreported as non-abundant to satisfy political interests of non-producing nations.

has reached a peak in off-shore wells and is now abundantly extracted from tar sand reserves.

“...a need to accelerate the development of alternative energy fuel resources in order to ensure energy security and reduce emissions,” - lines 5-7 (contrast)

“‘The common belief that alternative fuels such as biofuels...” - lines 18-19 (result)

“Instead of relying on those silver bullet solutions,”- lines 22-23 (consequence)

“However, these methods have a far higher carbon output than conventional drilling,” - lines 54-55 (reason)

“...the emissions produced during extraction as well as during usage.” - lines 57-58 (addition)

Alternative energy sources, like hydrogen, are still not foreseen as productive in the immediate future.

It is illusory to believe that the production of alternative fuels will make up for the decline in oil supply.

There is enough soil available in the world for the production of agricultural products to meet the needs of both food and energy.

It is more advisable to start using energy more efficiently than to depend on alternative solutions that are not yet entirely developed.

Using electricity for transportation and reducing the dependence on oil are unripe strategies that still have a minor impact in the current scenario.

stricter environmental regulations will impose even more restrictions on the already heavy challenges in oil supply.

more demand for oil will certainly not interfere with the current support for ecological programs to reduce carbon emissions.

further investments in newly found oil reserves will be the only alternative to help maintain future energy stability in the world.

shifting to fuel production from tar sands can reduce the oil problems, since tar sands are more abundant and less expensive to drill.

the exploration of lower grade resources seems to be the best solution to conform to the environmental policies in favor of low carbon emissions.
