Therefore you need 2.5
TW of PV in 25 years to cover 20 %.
According to the Department of Energy, in 2001 the world consumed at an average rate of more than 13 trillion watts (13 terawatts, TW), just a fraction of the 120,000
TW of energy available that falls to Earth - free.
To produce that much energy, they propose building power plants with a total of 6.5
TW of capacity.
By way of comparison, the US currently has about 1.2
TW of installed electric generation capacity, so this plan would involve expanding generation capacity fivefold in 35 years.
Temperature rose 1 * F during this time (540 terawatt - years can account for a buildup of 1650 (16 more zeroes) Additional heat will buildup from geothermal heat flow to maintain the necessary temperature between earth and atmosphere to dissipate the 44
TW of geothermal flow, but it is difficult to calculate the depth and extent affected.
As this paper states, «Covering 0.16 % of the land on Earth with 10 % efficient solar conversion systems would provide 20
TW of power, nearly twice the world's consumption rate of fossil energy and the equivalent 20,000 1 - GWe nuclear fission plants».
we need ~ 20
TW of carbon free power by 2050 2.
That still means 1.5
TW of nuclear power (supplying roughly 12,000 TWh (electric) per year of energy) would have a capital cost of $ 2.5 trillion or so.
For the sake of round numbers I'll assume 10
Tw of fossil fuel power for 2012 and 10,000 hours in a year, feel free to refine those if it seems necessary.
Systems are designed to have a probability of less than one in ten thousand for a core meltdown in any given year; but that could mean one every 5 years if nuclear supplied 2
TW of power, or one per year at the 10 TW or higher level (with roughly 10,000 nuclear plants worldwide).
The full potential there is enormous — some 40,000
TW of renewable energy in all, of which we tap only a tiny fraction with our present hydroelectric plants.
We are not going to supply the world with 68
TW of power by cobbling together a patchwork of 34 different technologies.
If I understand MARodger and the the Myhrvold - Caldiera paper correctly, approximately 1
TW of coal is used globally to generate electricity, which if continued to be used unabated, will be responsible for approximately 0.325 deg C in 100 years.
According to Archer and Jacobson's bottom - up estimates, which unlike Kleidon's are based on actual measurements of wind speeds, there is 1700
TW of wind power at an altitude of 100 metres over land and sea.
Modelling by Jacobson's team suggests that extracting 11.5
TW of this wind power would reduce the kinetic energy of wind at 100 metres by less than 1 per cent.

started watching arsenal in 2005 but thus far this has been my most disappointing season, ok other seasons have been disappointing but this one is my worst, arsenal fans have been too patient and forgiving for too long, zero planning for games, lack
of proper tactics before and during matches, same old excuses every season, lack
of proper transfers, poor replacements for great players who have departed, favouritism
of certain players eg ramsey, OG,
TW who perform poorly but still play while campbell, coq are benched..
