The proposal of rescue for The Earth against overwhelming global warming.

I would like to suggest to build wide orbital shelter (shield) to provide:

Primo: control global temperature by limiting Sun energy supplied to the Earth in controlled manner,

Secondo: produce electricity in controlled manner, next supplied to the Earth from the shelter (shield).

Proposal could be the rescue for overwhelming expected global warming and might be supply the amount of energy for the all Humans instead to produce electricity from fuel fossils.

The final effect shall allow:

Primo: keep The Earth temperature on the suitable level for all Human as limit energy supply from sun to the Earth,

Secondo : shut down all energy fabrication from fuel fossils as well as resign of oil/gas convergence for fuel for all cars or other machines.

Please note that current estimation of absorbed energy on the Earth surface is 238W/m^2 and a yearly average radiation on the Earth surface is determined to be 1367 W/m^2.

The proposed shelter (shield) on the suitable earth orbit , stationary or other with simplified geometry of 3000 X 2000 km shall supply (2000E3x3000E3x1367), it means more energy than 8.2 E+15 W x actual photovoltaic effciency of 0.1 =8.2 E+14 W of power, it means 820000000 MW, it means 820000000 x0.000001= 820 TW (terra wats).

Please note that annual net electricity generation in the world 2011y was estimated more than 20 000 TWh,

source -https://en.wikipedia...y_generation...

Therefore our 820 TW of power during yearly 8760 hours might supply annual electricity production of 7183 200 TWh it mean about 360 times more than 2011y annual generation of electricity from all sources (renewable, nuclear and fossil) on the whole world.

Please note that calculations presented above are very rare and technical solutions might be much more optimistic, when the mentioned orbital shelter (shield) can follow the sun (movable on the orbit) and exposition of sun will be much better than on average the Earth conditions.

PM. Sorry for Italian words.

 I can see a few problems, like which countries light are you proposing to block out?
