Our most 'great resource
The largest and most enduring sources of universal energy. Certainly the only real possible way to energy independence overall.
seems almost absurd that the solution to our energy problems could be within reach of everyone! Rich and poor, powerful and humble. Available daily. The energy source more "democratic" exists. The sun. That 'the lives of all, there has always been and always will be. As the sun was born and the life 'from the sun that everything continues to evolve. A perfect cycle that feeds during the day and off at night.
Ed and 'solar derived almost all other forms of usable energy on Earth.
The sun irradiates the earth and warms the atmosphere by moving air masses, thus giving rise to winds (wind) and rain (water), is to grow the plants (biomass), and so the animals (mechanical energy ) who died, over the millennia, become hydrocarbons (thermal).
He was adored by all the most ancient populations. Greeks and Romans (Apollo), Egyptians (Ra), the Aztecs (Nanauatzin) from the African Ashanti (Nyame), the Celts (Grann), from the Etruscans (Cautha) and the Hindu (Vishnu).
not needed then science and technology today is to understand that the most important resource for life on earth.
But we continue to run after the oil. Symbol of our prosperity today. Great accelerator that carries us from the 800 at full speed toward progress, although perhaps today, we begin to doubt that "progress" is the right word.
In these 200 years mankind has come a long way, and at an incredible rate if the measured on 40,000 years of human history "Sapiens Sapiens." In less than 200 years we have done 95% of all discoveries of all time, and our average life expectancy has risen from 35 years in 1800 to 70 years today.
But all this at an incredible cost. The most serious cost to be paid. What a world that may soon turn against them. It is starting to no longer stand.
I just thought at the beginning of the 900 on the ground were less than a billion people. We are now almost seven and by 2015 we could reach ten. A high number of folks who live with the lifestyle of today's eco-aggressive devastate the ecosystem in a few years. We think then to China, and India, whose economies still run almost entirely by coal.
So what are we waiting for? Why miss the opportunity now, we're "still" standing up, change our way of life and respect the world around us still fall into the perfect chain of the ecosystem from which we came out a few decades ago?
And it is that you must restart from the sun, which at this time there has never abandoned. That has never changed and that always takes us by the hand clear.
The strain energy we would do today to change our productivity is still relatively low. Solar thermal and photovoltaic as well as other sources, are still "cheap", because even on oil products.
One day, however, the total energy production might not meet demand and more production then prices would go up. We want to take the risk that you're wrong?
thought today would be enough solar panels to fill 40% of the roofs of houses and factories in Italy to cover the entire Italian energy needs.
Given that PV has a payback in 10 years or so (out of 30 panels guarantee), if today we decided to fully invest in solar, we would have a total return in 4 years and maintenance of every 90.
But that's another story. Revolutions are never done any day now ...
