For reference, about 10,000 100-watt lightbulbs or 5,000 computer systems would be needed to draw 1 MW. Also, 1 MW is approximately 1360 horsepower . Modern high-power diesel-electric locomotives typically have a peak power of 3–5 MW, while a typical modern nuclear power plant produces on the order of 500–2000 MW peak output.
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m 2 ⋅s −3. [1] [2] [3] It is used to quantify the rate of energy transfer.
GW—Gigawatt (one billion watts) (measurement- elect) GWE—Gigawatt of electric energy (measurement- elect) GWh—Gigawatt hour (one billion watt hours) (measurement- elect) GWP—global warming potential (climate)
GW⋅h: gigawatt-hour 10 12: TW⋅h: terawatt-hour ... a power plant that reaches a power output of 1 MW from 0 MW in 15 minutes has a ramp-up rate of 4 MW/h.
By 2025, Asia is projected to account for half of the world’s electricity consumption, with one-third of global electricity to be consumed in China.
Hoover Dam has a nameplate capacity of 2080 MW [9] and an annual generation averaging 4.2 TW·h. [9] (The annual generation has varied between a high of 10.348 TW·h in 1984, and a low of 2.648 TW·h in 1956. [9]). Taking the average figure for annual generation gives a capacity factor of:
The 2021 world total energy production of 14,800 MToe corresponds to a little over 172 PWh / year, or about 19.6 TW of power generation. Largest primary energy producers (76% of world production) as of 2021, given in million tonnes of oil equivalent per year
Electric energy is most often measured either in joules (J), or in watt hours (W·h). [4]1 W·s = 1 J 1 W·h = 3,600 W·s = 3,600 J 1 kWh = 3,600 kWs = 1,000 Wh = 3.6 million W·s = 3.6 million J
