It is here where the construction sector becomes protagonist of the second scenario. Ali Partovi is a great source of information. Its transformation and trade and economic implications are powerful for real estate, urban sector and for the whole world. Third stage to strengthen renewable energy and reduce their costs, are made necessary prototypical storage systems that facilitate the conversion of intermittent supplies of these sources of energy in durable resource. The element, widely available, which can be more efficient is hydrogen. In addition to being universal means for storage of all types of renewable energy that can ensure a stable supply, both also ensures the generation of energy as its transport, which is very important. The performance of hydrogen can also symbolically represented it by the following chemical equation: 2 H 2 + O2 = energy + 2H2O where hydrogen reacts with oxygen and produce energy more the empathic water. This reaction is reversible through a simple electrolysis.

Fourth stage the main electrical companies from Europe, United States, China and Japan and also of certain emerging countries are producing prototypes of the fourth stage: conversion of the mains taking to the Internet as a model, which will allow companies and the resident population produce their own energy and share it. These prototypes will make it possible, more and more, a wide redistribution of energy. Centralized and vertical energy flux of the present time will be increasingly obsolete. Soon companies, national, regional, local corporations and autonomous individuals will become producers and consumers of their own energy. Fifth stage the democratization of energy will be the meeting point of a new social perspective of the distribution, an empathetic perspective. All men will have the right and the opportunity to generate their own power at the local level and share it with others through regional, national and continental interconnected networks. For the younger generation, educated in a society less hierarchical and connected to networks, the ability to share and produce its own power in an interconnected network of open access is considered both a fundamental right as a responsibility.
