air conditioners and pool pumps. This includes coal, natural gas, petroleum, and retail electricity sales. It is estimated that approximately 4 percent of energy in the state is generated through renewable resources. Florida's energy production is 6.0% of the nation's total energy output, while total production of pollutants is lower, with figures of 5.6 percent for nitrogen oxide, 5.1 percent for carbon dioxide, and 3.5 percent for sulfur dioxide. In July 2007, Florida Governor Charlie Crist announced plans to sign executive orders that would impose strict new air-pollution standards in the state, with aims to reduce greenhouse-gas emissions by 80 percent of 1990 levels by 2050. Crist's orders would set new emissions targets for power companies, automobiles and trucks, and toughen conservation goals for state agencies and require state-owned vehicles to use alternative fuels. Governor Charlie Crist and both of Florida's senators, Bill Nelson and Mel Martinez, oppose offshore drilling and exploration. Former governor Jeb Bush, originally opposed to all drilling, changed his position on a bill introduced into the House of Representatives in 2005, which would allow unrestricted drilling or more from the coast. Martinez, Nelson, and Crist opposed that bill, but Martinez and Nelson voted for a Senate alternative which prohibited drilling within of the Panhandle coast, and of the peninsular coast. In 2006, the state enacted "Farm to Fuel" initiative, an effort to increase production of renewable energy from crops, agricultural wastes and residues produced in the state of Florida. On 22 January 2008, Florida's Agriculture and Consumer Services Commissioner announced funding for four commercial ethanol and biodiesel production facilities, and an additional eight demonstration and research projects. Oil and Gas Exploration There are two oil-producing areas in Florida. One is in South Florida, with 14 fields, and the other is in the western panhandle, with seven fields. The South Florida fields are located in Lee, Hendry, and Collier county. Florida’s first oil field, the Sunniland field, in Collier County, was discovered in 1943. It has since produced over 18 million barrels of oil. Subsequently, 13 more field discoveries were found. Although these fields are relatively small, production is significant. Together, the three Felda fields (West Felda, Mid-Felda, and Sunoco Felda) in Hendry County have produced over 54 million barrels of oil. Cumulative production from the Sunniland Formation through July 1993 was of oil. Production in the western panhandle began with the discovery of the Jay field
