Sentences with phrase «terawatts not»
Hoffert et al (1998)[the paper is here] provided what still is the clearest framework for establishing the huge magnitude of the energy technology challenge to meeting a growing energy commitment — a challenge measured in terawatts not gigawatts.

The bank's analysts forecast that Bitcoin mining could use up more than 125 terawatt hours of electricity this year, a level electric vehicles globally won't reach until 2025.
Some may argue this comparison is too simplistic and «apples to oranges» but the annual terawatt hour consumption figures persist none the less, and Bitcoin costs roughly 10x more energy than CERN Meanwhile, most, if not all of us will probably find it very difficult to demonstrate a cost / utility argument in support of Bitcoin having 10x more benefit than CERN.
So while the large - scale use of solar power could potentially affect the climate, the effects will be relatively minor so long as we don't capture hundreds of terawatts that would otherwise have been reflected straight back into space.
It means that by 2050 all of the world's energy demand above what we use now in 2003 — an additional 16 [terawatts]-- will have to come from some new energy supply that doesn't put a single atom of carbon into the atmosphere.
But the discussion is not entirely coherent: for example energy units vary across the chapters — total energy (for a year, or available from a given resource), can be seen here in terawatt - hours, terawatt - years, or exajoules, in some cases referring to thermal, in other cases electric power requirements.
As much as 100 clean terawatts, compared to today's dirty 15TW, is not inconceivable for the 22nd century.
CCS has not yet been commercially deployed at any centralized power plant; the existing nuclear industry, based on reactor designs more than a half - century old and facing renewed public concerns of safety, is in a period of retrenchment, not expansion; and existing solar, wind, biomass, and energy storage systems are not yet mature enough to provide affordable baseload power at terawatt scale.
