This is a facepalm on so many levels:

- oil company predicts oil will still be used in (a lot of) years

- oil company realizes that a) there is an incredible amount of energy in oil and b) the most efficient machines available use only small percentages of that energy

Dumping the remaining energy as heat in a climate-change world. Great!

Obviously, the contribution to global temperature increases due to the literal heat dissipation of engines is extremely, extremely negligible. Petroleum can cause changes to global temperatures through the release of carbon, which changes the Earth's insulation, but no through actual heat.
