The Solar Alternative. The way humans use resources to product electricity is changing because the current systems in place are based on 100 year old technologies that are a limited ending resource. (i.e. Oil and Coal) These technologies are inefficient, costly, and environmentally dangerous to mankind.

The catalysts for change have already set in motion the next generation of change in the fields of energy. The elements for this change are reduced available resource, price, and more technological advances that make alternative energies as a better viable resource to use.

The die is cast, the energy paradyme shift is happening today and alternatives are now available unlike never before that are more cost effective and a healthier choice for you.

Here with Watch Documentaries 360 in the series of Extreme Engineering in this episode Solar Power Revolution.

Welcome to the 21st century. Things are gonna be different. Energy, sustainable energy is something that our kids care about and the mainstream public cares about. And renewables has to be part of the solution.

In a economy burdened by the costs of increasingly scarce oil and natural gas and a planet already feeling the impact of fossil-fuel-driven climate change, the technological revolution of our time is renewable energy. Sunlight, wind, water, geothermal heat and plant biomass are all, essentially, limitless resources.

And they're all proven technologies that work right here, right now. The sun provides the Earth with unfathomable amounts of energy. In one hour, the Earth receives more energy from the sun than the entire human race uses in a year.

With current technology, photovoltaic panels covering 10,000 square miles  or about 10% of the land area of Nevada could provide all of the electricity used by the United States.
Although photovoltaics converting the sun's light to electricity was not discovered until the 20th century, solar thermal harnessing the sun's heat is an ancient practice.

Perhaps the earliest use of solar thermal technology was the south-facing home. Ancient cultures, including the Anasazi Indians of the American Southwest, designed their buildings to face south, to maximize heat from the sun, which stays low in the southern sky during winter.
In the summer, when the sun is high in the sky, the cliff face that extended over the building provided cooling shade. It's still a common design today.
