Energy Problem: Solutions

World has an unquenchable appetite for energy. From motor vehicles for taking us from one place to another, air conditioners and heaters to keep our offices and homes livable, airplanes to takes us across the world, computers, telephones, mobiles and networks to help us communicate and do business, everything, today needs some form of energy.
As the populous developing countries, such as India and China, grow with rapid rate, increasing the standard of living of their citizens, the demand for more products will keep on growing. As the demand for more products increases, so will the demand for the energy to produce those goods.
The conventional form of producing energy from oil, coal are known to be cause of carbon emission issues and the ensuing environmental issues such as global warming.
According to the statistics by OICA, countries like China, India are seeing 25% increase in the production of cars each year. This has created increase demand for crude oil thereby pushing the crude oils costs to highest ever. The cost of barrel has increased from $15 per barrel in 1994 to $30 in 2000 to current rate of more that $80 per barrel (OPEC stats).
Looking at the current environmental issues, the cost of crude and ever growing demand for the much needed energy, made me think : What could be the prospective solution for the worlds energy problem ?

From all the potential source of generating power, such as wind turbines, hydroelectric power plants, thermal plants, nuclear power plants, the nuclear energy seems to be the potentially most viable solutions. It has possibly the lowest environmental impact in terms of carbon emission. Power from nuclear energy sounds like the option of the future.

But generating power from nuclear reactors invoke strong reaction from the citizens of the world due to two reasons:
1) Safety issues of the reactors.
The Chernobyl incident is quite vivid in the memories of the people. A single nuclear meltdown can cause great impact on the environment and the living organism in wide area due to radiations. (list of civil nuclear accidents)
2) Dealing with the spent radioactive waste. Some of the options such as deep bore-hole disposal do not sound like long term solution.

Due to these known issues, the nuclear reactors need to be built in the isolated part of the earth away from densely populated human areas. But that is a temporary solution.
So, provided human race make huge technological developments, a good solution would be to build nuclear reactors not on earth but on some other place such as moon or other planets.

This will solve the problem of nuclear waste and also remove safety concerns.
Even if we can create nuclear reactor on moon, the issue of transmitting energy from the moon to the earth poses a next bigger challenge. Do we hang cables from the moon ? The only way to transmit energy through such distant place is through light.

So, the solution to the energy problems of human race is to have a nuclear reactor in space which transmits energy as light.

But, wait a minute ! Doesn't the sun solve that ? Ironic isn't it ? The solution of the future exists today !
