1 They consume around 40 terawatt hours of electricity in the US every year.

2 "You'd need a terawatt [or trillion-watt] laser to pull a person," says Grier.

3 The EU Commission projects the ban on the energy-inefficient bulbs will save about 40 terawatt hours of energy in the EU per year -- enough to meet the energy demands of a small country.

4 ABSTRACT In this dissertation, theoretical and experimental studies of terawatt chirped-pulse amplifier system are presented.

5 Meanwhile, the chirped pulse amplification technique has boosted the peak power of the pulse to the terawatt level.

6 This paper introduces the development of CPA system and describes the structure and function of our table femtosecond terawatt CPA system.
