Why Solar Power is Such An Underutilized Resource

Solar power has been in the news and discussed since the 1970’s. So why isn’t being utilized more in the United States?

Germany, a country half the size of Texas, harnesses the sun’s energy for many of its residential homes as Mayor Peduto found out earlier this year

Joylette Portlock, President of Communitopia and creator of the Don't Just Sit There, Do Something About Climate Change web series, thinks that Pittsburgh can better utilize the sun’s rays for energy.

"The idea of harnessing the sun's energy for power has been around since the industrial revolution started, it's been around for a long time.  Just as a country, we've had the notion that fossil fuels were cheaper or more easily available, easier to exploit, and we've really built up the infrastructure around those.  And it's only when you get to periods of time, like we saw in the 70's with the oil crisis, where people change their focus and say 'hey, maybe we shouldn't be depending on other countries for our energy,' or maybe, 'we should find a fuel that's free.'"

Extreme weather, greenhouse gases, carbon monoxide and glacial melting; all these buzzwords have increasingly entered the public vernacular in the past 20 years. 

Following a UN report by the World Meteorological Organization, scientists expect that the topic of global warming and climate change will continue to be a hot issue.  The report, “The Global Climate 2001-2010: A Decade of Extremes,” cites that the past decade has seen an abundance of greenhouse gas emissions that has caused increased temperatures on both hemispheres, all oceans and an accompanying rapid decline in arctic sea ice and glaciers. 

Director of Science at the Carnegie Science Center, John Radzilowicz, has been following the topic of global climate change and was not necessarily surprised by the UN report.  He was optimistic, however, that the report was gaining attention and combined a multitude of data pointing to the extremes in weather conditions throughout the world.
