According to a new study by the energy analysts at Wood Mackenzie, the cost of solar power is expected to decrease another 15%-25% over the next decade due to developing technologies already in the pipeline, which could make it the lowest-cost power source in the U.S. by 2030.  Solar is poised for both U.S. and world domination — it is the cheapest form of new power generation in markets including Spain, Italy, India, and 16 U.S. states.  In the next decade, solar will become dominant in every U.S. state as well as Canada, China, and 14 other countries.  Why? Because the cost of solar has dropped by 90% since 2000.
