:While the construction of solar panels through the use of rare earth minerals is still a kink that has to be worked out, solar energy is still a promising alternative for of energy that can really elevate all humankind as we progress into the future.  We're going to run out of the resources we're currently burning through at some point, so it's really in our best interest to start coming up with permanent alternatives now, as opposed to waiting until it's too late.  If you're looking to get your kids informed about solar energy, you could always pick them up from educational solar power kits.  Here are a few amazing facts about solar energy you might not have been aware of.

 

Energy - The Speed of Light

The Speed of Light


Although the sun is over 90 million miles from the Earth, it takes less than 10 minutes for light to speed across that distance.  In most practical cases, light and other electromagnetic waves can be thought of as moving instantaneously, but for long distances and very sensitive measurements their finite speed has noticeable effects.  Still, considering that vast amount of distance, 10 minutes is next to nothing.

 

Solar Energy - Been Around the Block

Been Around The Block



Solar energy has been used for over 2700 years; in 700 BC, glass lenses were used to make fire by magnifying the sun's rays.  Given that the sun is a powerful source of energy, it only makes sense that man has been working to harness it's strength for thousands of years.  Imagine what we'll be able to do with it in another three thousand years.

 

Solar Power -I've Seen Bigger

I've Seen Bigger



The largest solar power plant in the world is located in the Mojave Desert in California, covering 1000 acres.  Several other places in the world have large plants as well, but none can come close to what they're working with out there in California.   Solar Energy Generating Systems is the name given to the nine solar power plants in the Mojave Desert.  They were built in the 1980s, and are the first commercial solar plant.  These plants have a combined capacity of 354 megawatts. It's all of these reasons that make them the largest solar power installation in the world.

 

Renewable Energy - There's No End

There's No End



Solar energy is lauded as an inexhaustible fuel source that is both pollution and noise free.  The technology is also versatile.  For example, solar cells generate energy for far out places like satellites in Earth orbit and cabins deep in the Rocky Mountains as easily as they can power downtown buildings and futuristic cars.  Seeing as the sun has several billion years of life left in it, there's never going to be an end to using it as a resource.

 

Solar Energy - Diverse Applicationa

Diverse Applications



Solar thermal power creates electricity by heating water into steam.  This heat can be used to warm the air in your home or the water for your morning shower.  Heating is the most obvious application for solar thermal power, but solar cooling can be achieved for a building or district cooling network by using a heat driven pump.  The greater the driving heat from insulation, the greater the cooling output.  One of the first examples of this dates back to 1878, when Auguste Mouchout pioneered solar cooling through making ice using a solar steam engine attached to a refrigeration device.
