As we rapidly approach peak oil, we must begin to consider what our energy future will look like. It’s clear that renewables will be an essential part of it, but we won’t be able to completely replace fossil fuels with renewable energy sources. We must make significant changes to the way we live, including transforming our transportation system.
The peak oil concept
The concept of peak oil is simple. Geologists have determined that any finite mineral substance on earth is produced in a bell curve. When you've reached the peak of that curve, it means you've used half of this resource. Based on this model, most of the resources we depend on will eventually peak, with the exact timing of those peaks depending on our consumption.
