The IMF estimate that in 2020 less than half of supplied electricity was billed and less than a quarter paid for. The economics of Iraq's electricity sector is characterized by significant challenges related to supply, demand, infrastructure, and financial sustainability. These issues are compounded by the country’s historical context of conflict, sanctions, and ongoing instability.

Muhaisen and Gadi (2006) demonstrated that deep and long courtyards would reduce energy consumption because of the shading effect of their configuration. Hence, a shallow courtyard is more suitable for a cold climate because its configuration will increase solar gain and decrease heating loads during winter.

Storage generates revenue by arbitraging inter-temporal electricity price differences. If storage is small, its production does not affect prices. However, when storage is large enough, it may increase prices when it buys and decreases prices when it sells. The price arbitrage transfers surplus between producers and consumers.

Finnish researchers have installed the world's first fully working "sand battery" which can store green power for months at a time. The developers say this could solve the problem of year-round supply, a major issue for green energy. Using low-grade sand, the device is charged up with heat made from cheap electricity from solar or wind.

LAES is based on the concept that air at ambient pressure can be liquefied at −196 °C, reducing thus its specific volume of around 700 times, and can be stored in unpressurized vessels. During peak electricity time, the liquid air can be expanded in a generation system (e.g. turboexpander, reciprocating engine) to produce electric power.
