Another scientific article is out on the health effects of air pollution, and this one exposes both the long and the short of it. The comprehensive study proves what numerous other studies and common sense told us: air pollution hurts us. "Hospitalizations for several common diseases—including septicemia (serious bloodstream infection), fluid and electrolyte disorders, renal failure, urinary tract infections, and skin and tissue infections—have been linked for the first time with short-term exposure to fine particulate air pollution (PM2.5)."

Borrego Solar Systems and sPower worked with the Six Flags Discovery Kingdom this year to manifest the first theme park on the West Coast powered by solar energy. In this case, the solar will account for 80% of the park’s energy usage. One difference in this theme park's solar installation from other similar installations is that it will be powered by one of the most substantial solar carport installations in the country
