The energy return on energy invested (EROEI) of crude is declining

The energy return on energy invested (EROEI) of crude is declining

Renewables do not provide a comparable substitute for crude oil and the liquid fuels that are refined from it, since the potential contribution from biofuels is relatively minor. Replacing the UK’s 34 million oil-powered vehicles with electric versions is an unlikely proposition, given the limitations of time and resources such as rare earth metals. Mass transit is the more likely future for electric transport than personal cars. The end of cheap, personal transport is a real possibility and may seed changes in our behaviour, such as building resilient communities that produce more of their essentials, such as food and materials, at the local level.
