			The single biggest drawback of using electricity as an energy currency is that it is very difficult to store electricity. Electricity generated on the [[electrical grid]] must be used immediately (within thousandths of a [[second]] after it's produced). This is why [[energy storage]] technologies like [[pumped storage]] and batteries are so important for [[intermittent electricity\|intermittent power source]]s like [[wind power]] and [[solar power]]. The electrical grid must carefully monitor demand in order to make sure that enough electricity is produced to meet the immediate demand.

			==Why is Electricity an Energy Currency?==
			[[Electricity]] is a popular energy currency because it is so flexible in that it has many more uses than some primary energy, such as [[oil]]. Electricity can run [[household electronics]] and [[light bulb]]s, cook a meal, [[home heating\|heat houses]], or even run an [[electric vehicle]]. Electricity is the most flexible form of [[energy]] now and for the foreseeable future. Crude oil, on the other hand is a [[fuel]] that must be separated into a number of different useful products through a refining process.

			Since electricity is such a popular form of energy currency and finds so many uses, its use is growing extremely fast. This growth worldwide can be seen in the simulation below. Note that some third world countries have low levels of electrification, while other modernizing countries have a quickly expanding electricity use. To get some idea of how electricity is growing compared to total energy look at the line chart below. This shows that the flexibility of electricity creates a strong incentive to have as great a fraction of energy produced in that form as is possible. To get some specific details, click on different years and notice how the fraction of the [[total final consumption]] that is electricity grows with time (for most countries). Click on different countries on the map to find country specific data.
