Cuidado Alb !
Las "burbujas" no son el único modelo especulativo.
Si el Estado se decide a subvencionar una determinada actividad, la misma "florece" y, hasta se desboca (si el estímulo es exagerado).
...
Y cuando se desboca se acaba construyendo donde no se consume:
"What's more, China's large solar farms are largely in less densely populated areas in the west of the country, far from population centres like Beijing or Shanghai, in the east.
Building extra grid capacity to transfer it is time-consuming and expensive. This leads to a problem known as curtailment - a solar farm produces, say, 20 megawatts of electricity but can only find buyers for 15 megawatts."

"China is a large producer of polysilicon, for use in first generation solar cells around the world.
Made from the Earth's most abundant substance -- sand -- polysilicon is tricky to manufacture. It requires huge amounts of energy, and even a small misstep in the production can introduce impurities and ruin an entire batch. The other main challenge is dealing with the waste. For each ton of polysilicon produced, the process generates at least four tons of silicon tetrachloride liquid waste.
When exposed to humid air, silicon tetrachloride transforms into acids and poisonous hydrogen chloride gas, which can make people who breathe the air dizzy and can make their chests contract.
Estimates that Chinese companies are saving millions of dollars by not installing pollution recovery.
He said that if environmental protection technology is used, the cost to produce one ton is approximately $84,500. But Chinese companies are making it at $21,000 to $56,000a ton. "

Tal vez lo mejor de todo es que logren acabar en unas décadas con el exceso de población en esa parte del mundo.
Todo gracias a que en esa parte del mundo se unen dos de las peores facetas sociales que ha dio el anterior siglo: la de un gobierno dictatorial sin control ni contrapoderes y la de una economía neo-capitalista sin control medioambiental ni sindical.
