Energy Fuel Supplies

When energy is discussed, the subject of fuel reserves often arises. In particular, opponents of nuclear energy point to a few decades of proven reserves as a reason to abandon one of the very few effective countermeasures available against climate change.

The point that needs to be understood is that proven reserves are only a fraction of the resources that really exist. For example, the world has less than a three-years' supply of oil if only proven reserves are considered. No one really believes the world will run out of oil in three years. In comparison, projected resources show over 600 years' supply of oil, maybe a thousand years' supply of coal, and 30,000 years' supply of nuclear fuel. Even if all the world's electricity comes from nuclear energy and the rate of electricity use triples, nuclear fuel will last over a thousand years. Renewable energy and energy efficiency can stretch the supply longer. A thousand years should be enough time to develop other solutions, such as fusion energy and energy storage.
