Wind and solar met 80% of demand growth in 2022, while all renewables together (wind, solar, hydro, bioenergy and other renewables) met 92% of the increase in demand. An increase in coal generation (+108 TWh) met the remaining increase in demand (8%) as well as the shortfall in nuclear and gas generation. Other fossil fuels also rose to cover the remaining shortfall (+86 TWh). The IEA Net Zero Emissions scenario shows that from 2021 to 2030 we need to raise wind and solar generation around five times (solar seven times and wind four times), other clean electricity needs to rise 54%, and this would halve coal power (-54%) and reduce gas power by 24%.
Fluctuations in market value shall not be recorded but a permanent impairment in the value of securities shall be recognized in the accounts. When securities are written off or written down, the amount of the adjustment shall be charged to account 426.5, Other Deductions, or to an appropriate account for accumulated provisions for loss in value established as a separate subdivision of this account. A. For the purpose of avoiding undue refinement in accounting for additions to and retirements and replacements of electric plant, all property will be considered as consisting of (1) retirement units and (2) minor items of property. Each utility shall maintain a written property units listing for use in accounting for additions and retirements of electric plant and apply the listing consistently. B. As far as practicable, the determination of pay roll charges includible in construction overheads shall be based on time card distributions thereof.

Pulverized fuel equipment, including pulverizers, accessory motors, primary air fans, cyclones and ducts, dryers, pulverized fuel bins, pulverized fuel conveyors and equipment, burners, burner piping, priming equipment, air compressors, motors, etc. D. Records supporting this account shall be kept so as to show separately the book cost of each franchise or consent. D. Records with respect to entries to this account, as described above, and the account balance, shall be so maintained as to show the factors of calculation with respect to each annual amount of the item or class of items. B. If accruals for taxes are found to be insufficient or excessive, correction therefor shall be made through current tax accruals. B. This account shall be maintained in such manner as to show the amount of each separate provision and the nature and amounts of the debits and credits thereto. B. Amounts paid by the utility for the purposes for which this liability is established shall be charged hereto.
(See item 3, above.) When a particular construction job requires the use for an extended period of time of special machines, transportation or other equipment, the net book cost thereof, less the appraised or salvage value at time of release from the job, shall be included in the cost of construction. Iran’s electricity demand has grown by 212% (+251 TWh) in the last two decades, from 119 TWh in 2000 to 370 TWh in 2022. This is considerably faster than the global demand increase of 90% over the same period. Emissions intensity in 2022 (494 gCO2/kWh) was slightly below 2000 levels (535 gCO2/kWh), due to increases in hydro and wind and the introduction of solar into the mix. Because of the majority fossil fuel grid, total annual power sector emissions have increased by 187% (+119 million tonnes of CO2) over the same period, roughly in line with the demand increase.
The global electricity system is transforming – but not yet fast enough

Fossil generation in the EU and US both peaked in 2007, and then in Australia in 2009, Japan in 2012 and South Korea in 2018. However, none of these countries are also contending with rapid growth in electricity demand. Green hydrogen is essentially a form of electricity storage, the result is no net electricity generated, but rather the flexibility to match demand to variable supply. Surplus clean electricity on windy or sunny days can be converted into hydrogen, stored, then burned when there is limited wind and sun.
Global electricity emissions increased by 160 million tonnes of CO2 (+1.3%), reaching 12,431 mtCO2 in 2022. It was a smaller increase than in 2021 when emissions saw a record rebound due to the economic recovery from wholesale accounting Covid-19 (+797 mtCO2, +7% year-on-year). Emissions intensity decreased slightly from 441 gCO2/kWh in 2021 to 436 gCO2/kWh in 2022, while emissions per capita increased from 1.55 tCO2 to 1.57 tCO2 per capita.
