Reserve some energy

Are energy reserves a subset of resources?

Reserves include only recoverable energy. “Resources” represent that portion of the energy that is known to exist or even suspected to exist, irrespective of technical or economic viability. So reserves are a subset of resources. Annual consumption and available reserves of different non-renewable energy sources for the United States and the world.

What is energy resource vs energy reserve?

An energy resource is defined as the whole or total estimated and anticipated amount of energy that should be extractable from an energy source, even if some part of it is currently undiscovered, hypothetical, or inaccessible. The relationship between energy resource vs. reserve is that an energy reserve is part of the overall energy resource.

What is the difference between a reserve and a resource?

The most commonly used terms are “reserves” and “resources.” "Reserves" represent that portion of demonstrated resources that can be recovered economically with the application of extraction technology available currently or in the foreseeable future. Reserves include only recoverable energy.

Why do we need a power reserve?

The growing dependence on variable wind and solar power resources make it more necessary to balance reserves to cover minute-to-minute and hour-to-hour variability and uncertainty. Additionally, other power electronic interfaced resources (such as battery storage) and electronically-coupled load also can respond quickly if required after an event.

How can we predict the life of energy reserves?

In the case of energy reserve, although we know that we might find new resources, we do not know how much we could find. But the consumption can be predicted with some accuracy based on the past rates. We can calculate the life of current petroleum reserves by dividing the current reserves by current consumption.

How are energy reserves formed?

Energy reserves in heavy oil, oil sands, oil shale, and methane hydrates are formed through advanced stages of petroleum decay. Estimated reserves in these sources dwarf known reserves in coal, natural gas, and petroleum.
