1. A system for providing cooling and power, the system comprising:
a meter configured to receive first electrical energy from a power source and provide at least a portion of the first electrical energy to a data center during a first time period, the data center comprising multiple electronic devices that generate heat while in operation;
an electrical-to-mechanical energy conversion device configured to convert air at approximately atmospheric pressure to a compressed or liquified state using at least the portion of the first electrical energy received from the power source during the first time period;
a storage container configured to receive the air from the electrical-to-mechanical energy conversion device and store the air in the compressed or liquified state;
a mechanical-to-electrical energy conversion device configured to, during a second time period in which the meter does not provide the first electrical energy to the data center:
receive the air from the storage container in a gaseous, compressed state;
generate second electrical energy for powering the data center using the air received from the storage container; and
exhaust cooled air for providing to the data center to cool the electronic devices; and
a heater configured to (i) receive thermal energy generated by the electrical-to-mechanical energy conversion device and (ii) use the thermal energy to heat the air from the storage container from the compressed or liquified state to the gaseous, compressed state before the air is supplied to the mechanical-to-electrical energy conversion device,
wherein the second time period comprises a period of time during which the first electrical energy from the power source is not cost efficient.
