The UK parliament has passed several measures to compel energy companies to reduce CO2 emissions. Parliament has also enacted several plans to induce businesses and home owners to adopt energy saving measures and renewable technologies. One of these measures is the Feed In Tariff. The FIT in the UK started out at 41.3p per Kw/h produced for a homeowner with solar on the roof. Lower payments for commercial solar arrays and solar farms were available. Wind energy and hydroelectric energy systems also received FIT payments as do anaerobic digesters and other methods of generating energy using a renewable source. All of these FIT payments cost little to the average consumer of electricity and created a large increase in the installation of solar systems, wind farms and other renewable energy systems.
