Worldwide investments in clean energy projects have hit a six-year low. Global spending totaled $117.6 billion in the first half of 2019, down 14% from a year earlier and the least since 2013, according to a report by BloombergNEF. Investments slowed in all three major markets -- the U.S., Europe and China -- but China’s decline was especially pronounced as the country continued its shift away from subsidies for solar and wind power.

Alabama is ranked 13th in the nation as having the greatest solar potential, yet only 0.26% of its energy comes from solar, leaving the state far behind others when it comes to total installed solar capacity.
