Cities, states, and nations are investing in clean energy production through policies and incentives, like feed-in-tariffs that provide above-market prices for producers in some European countries. Tax credits, rebates, and other incentives across the United States enable solar to compete with fossil-fuel-burning energy supplies. 

Solar power has enormous potential to reduce greenhouse gasses and reduce energy costs, and the extent of their success depends heavily on optimization. Important considerations include high voltage vs. low voltage electrical distribution systems, utility integration, power systems analysis, lighting, communications, motor controls, solar power, programmable logic controller (PLC) programming and more.
