This is a special guest post from Kriss Bergethon, owner/founder
of Solar Sphere. Solar power as we know it has been around for
almost a century. Many people believe that its still the same
basic technology that helped power early spacecraft and the
White House in the 1970′s. But advancements over the past 10
years have brought solar to the cutting edge with new investment
and an emphasis on research. Here are three solar innovations
that are making this type of renewable energy more affordable,
easier to obtain, and more efficient for generations to come. 1.
Thin-Film Cells Will Cut Solar Costs in Half When most people
picture solar panels, they think of the large black cells with
aluminum framing that resemble windows. These are crystalline
panels and have been used for decades. The problem with them is
that they are time and energy consuming to make. Similar to the
process for making silicon computer chips, the manufacturing
process requires highly trained technicians, clean rooms, and
energy-gobbling mach
