This graph shows that the cost of solar power has declined substantially over the past few decades. You can click on it to see it more clearly. I found it on ThinkProgress.org via LeisureGuy’s blog.
This leads me to wonder: Are we at a point in history in which the U.S. may finally start taking alternative energy seriously? Many countries already have, but in the U.S. there is still tough resistance to it from Republicans and the business community, especially the oil and natural gas industries. Pres. Obama has tried to pass laws that put restrictions on these businesses to force them to decrease their pollution and their heavy use of fossil fuel, but such efforts have had mixed results.
I’m hoping that when businesses and individuals realize that the cost of solar power has gone down, they’ll be more willing to give up the old way of doing things. Until alternative energy becomes more cost effective than fossil fuel, very few Americans will be willing to use it.
