A terawatt (TW) is equal to one trillion watts, which is represented numerically as 1,000,000,000,000 watts. In terms of zeros, a terawatt has 12 zeros following the digit 1 (1 followed by 12 zeros). This is the same for other terascale units, such as terabyte, which is one trillion bytes.
The terawatt is equal to one trillion (1012) watts.
World energy consumption is about 5 terawatts of oil, 4 terawatts of coal, 3 terawatts of natural gas, 1 terawatt of nuclear power and half a terawatt of hydroelectric power. That is about 13.5 terawatts combined.
There are 1,000 terawatts in one gigawatt. This is because one terawatt is equal to one trillion watts, and one gigawatt is equal to one billion watts.
1,000,000 megawatts or 1x10^12 watts which is 1,000,000,000,000 watts. The average laptop uses 15 to 60 watts to put that number in perspective.
There are 1 million kilowatt hours (kWh) in one terawatt hour (tWh).
One exajoule is equivalent to approximately 0.2778 terawatt-hours. Since a terawatt (TW) is a unit of power and not energy, to convert exajoules to terawatts, you would need to consider the time period over which the energy is consumed or produced. For instance, if you spread one exajoule over one hour, it would be approximately 277.8 terawatts for that hour.
Electric power plants produced 17,320 terawatt-hours (TWh) in 2005. In 2030, the world is projected to need about 33,264 TWh-nearly double the amount of 2005. (Source: 2008 EIA International Energy Outlook Report.)
The world's daily energy consumption is around 160,000 terawatt-hours (TWh). This includes energy used for heating, transportation, electricity, and industry. About 80% of this energy comes from fossil fuels like coal, oil, and natural gas.
South Korea's total annual energy consumption is approximately 538 terawatt-hours. The country relies heavily on imported fossil fuels for its energy needs, but is also investing in expanding its renewable energy sources to reduce its carbon footprint.
