Title: Economy of Puerto Rico
Content:   Puerto Rico does not have any coal, natural gas, nor oil reserves so it must import all its fuel in order to produce energy. The Puerto Rico Electric Power Authority (PREPA), a government-owned corporation, produces 70% of all energy in Puerto Rico through several power plants dependent on fossil fuels. 58% of PREPA's budget goes directly to these costs. Additional indirect costs of imported fossil fuels are paid through power purchase agreements for the 30% of the country's energy produced through private companies dependent on fossil fuels. To meet energy demands, Puerto Rico must import oil at a rate of 8.0 billion kWh and about 1,499,196 km3 of natural gas per year as well as a very

Perplexingly, less than 3% of all energy is produced through renewable energy even though Puerto Rico enjoys more than 65% sunny hours per day in average and 19-knot (22 mph; 35 km/h) winds year round. The island could also generate all its energy through hydroelectric dams thanks to its local geography which features many rivers but it has opted to leave that industry behind. Public policy has also opted not to pursue nuclear power either. Biofuel, biomass, geothermal energy, wave power and tidal power are still in its infant stages although there are some microbusinesses providing energy from those sources or performing research on the subject. The Puerto Rican government has made plans to

As a result, Puerto Ricans pay 26¢ per kilowatt per hour of electricity, compared to an average of 11 to 12 cents or less across the United States. This places Puerto Rico at an enormous disadvantage when compared to other states that produce electric power at less than half of Puerto Rico's price. Electric utility costs ultimately create a ripple effect on the economy as it adds to the cost of living and the cost of doing business. For example, 20% of Bacardi's expenses on the island come from electricity, while the company that owns all Wendy's, Applebee's, and LongHorn Steakhouse

This forces PREPA, the government-owned corporation and government monopoly that owns and manages all electric power distribution and transmission, to spend 58% of its operational expenses in fuel purchases alone. In terms of food production, Puerto Rico imports 85% of its food even though most of the land is fertile with only a mere 6% being arable. This perplexing situation has been caused due to a shift in priorities towards industrialization, bureaucratization, mismanagement of land, lack of alternative methods, and a deficiency in the number of agricultural workforce. Similarly, 
Title: Antonio S. Luchetti
Content:  Despite the fact that Puerto Rico had no coal or oil for energy development, there were many rivers to supply electrical needs via hydroelectricity. Luchetti was at time executive director of the Utilización de las Fuentes Fluviales (later known as the Autoridad de las Fuentes Fluviales, or AFF, and now called the Autoridad de Energía Eléctrica or PREPA). He judged that what the government of Puerto Rico needed to do at the moment was to purchase the three private electric companies operating in the island: the Ponce Electric Co., the Porto Rico Railway Light & Power Company, and Mayagüez Light, Ice & Power Co., and concentrate on building and island-wide energy infrastructure. He estimated the cost at $7 million.
Title: Puerto Rico Electric Power Authority
Content:  The majority of Puerto Rico's electricity is generated using oil and natural gas fired power plants. Puerto Rico also has 21 reservoirs that produce hydroelectric energy. In 2019 the Puerto Rican government passed legislation requiring the closure of coal fired power plants by 2028 and achieving 100% renewable energy by 2050. A report in 2021 criticized the government for delays in processing applications for electrical interconnection. At the time of said report only 327 applications where approved, representing 0.09% of the total. In 2021 the government unveiled plans for the Puerto Rico Ocean Technology Complex (PROtech) an Ocean thermal energy conversion project on the southeast coast.

The water industry is administered in whole by the Puerto Rico Aqueducts and Sewers Authority (PRASA), another government-owned corporation and government monopoly which owns and manages all the water supply network in Puerto Rico. All potable water comes either from raw water (primarily rainwater, lakes, and rivers) or sewage treatment subject to regulations by the Department of Natural and Environmental Resources of Puerto Rico (DRNA), the Environmental Protection Agency (EPA), the Puerto Rico Environmental Quality Board (JCA in Spanish), and the Safe Drinking Water Act. The water bottling industry is diverse with several plants on the island.

Content:  The political class has proven to be highly stubborn when examining existent public policies. This stubbornness ultimately forced Puerto Rico to incur in higher opportunity costs. For example, even though the island's geography features many rivers, the government has opted to leave the hydroelectric industry behind. Public policy has also opted not to pursue nuclear power either. Instead, even though Puerto Rico does not have any oil-based resources, it has opted to power its electric plants with fossil fuels: less than 3% of all energy is produced through renewable energy even though Puerto Rico enjoys more than 65% sunny hours per 
Title: Puerto Rico Electric Power Authority
Content:  The Puerto Rico Electric Power Authority (PREPA; Spanish: Autoridad de Energía Eléctrica de Puerto Rico, AEE) was an electric power company owned by the Commonwealth of Puerto Rico responsible for electricity generation, power distribution, and power transmission on the island. PREPA was the only entity authorized to conduct such business in Puerto Rico, making it a government monopoly, until on January 22, 2018, then-governor of Puerto Rico, Ricardo Rossello, announced that all assets of the company will be sold in a general privatization of PREPA. The authority was ruled by a board of directors appointed by the governor with the advice and consent of the Senate. Since 2014, PREPA was subject to the Puerto Rico Energy Commission, another government agency whose board of directors was also appointed by the governor. Hurricane Maria in September 2017 destroyed PREPA's distribution network, creating a blackout in all parts of the island.
