"Why the U.S. Power Grid's Days Are Numbered"
"After subsidies, solar power is competitive with grid power costs in large parts of those markets. Some areas in the Northeast will reach a similar “grid parity”—where residential solar is equal in cost to power from a utility—within three years; a majority of states could get there in 10 years or less, according to data from a variety of green energy and regulatory sources. A July report by Navigant says that by the end of 2020, solar photovoltaic-produced power will be competitive with retail electricity prices—without subsidies—“in a significant portion of the world.”
...
The solar and distributed generation push is being speeded up by a parallel revolution in microgrids. Those are computer-controlled systems that let consumers and corporate customers do on a small scale what only a Consolidated Edison or Pacific Gas & Electric could do before: seamlessly manage disparate power sources without interruption.
...
The grid continues to shrink—U.S. power use actually peaked in 2007—as distributed generation captures an increasing share from utility-generated power. There won’t be much need for new large-scale transmission lines after that, except perhaps to gather and distribute power from remote wind farms. Crane says at least some existing transmission lines “are about to become stranded costs”—utilities simply won’t require the capacity they have now."
A rede eléctrica, como a conhecemos, terá o mesmo destino que a rede de telefones clássica, por terra. Mongo também passará por aqui, para criar um mundo menos centralizado, mais auto-suficiente, e mais antifrágil.

"Forget Tech Startups. Now 'Microbusinesses' Drive Job Creation"
"A report (PDF) published on Wednesday by the California Association for Micro Enterprise Opportunity, comes to a different conclusion. What the group calls microbusinesses, meaning ventures with between one and four employees, created 5.5 million jobs between 2004 and 2010, its analysis of government data found. That’s more than any other size-category of business during the same time period. Microbusinesses were the only category to add jobs in 2009 and 2010, when companies with more than 20 workers shed millions of jobs."
