Hawaii had one coal-fired generating stations in 2005, with 203 MW of capacity, representing 7.8% of the state's total electric generating capacity; Hawaii ranks 45th out of the 50 states in terms of coal-fired electric generating capacity.[1] In 2006, Hawaii's sole coal-fired power plant produced 1.6 million tons of CO2, 900 tons of sulfur dioxide, and 1,000 tons of nitrogen oxide; this coal-fired power plant was responsible for 7.6% of the state's total CO2 emissions.[2] In 2005, Hawaii emitted 16.9 tons of CO2 per person, slightly less than the U.S. average.[3]

No coal was mined in Hawaii in 2006.[4]

Citizen activism


There is no history of coal mining in Hawaii, as the state has little or no coal reserves.[5][6] The coal power industry is also very weak in Hawaii - the state's sole coal-fired power plant was built in 1992, and there are no active proposals to build new coal-fired power plants in the state. In 2005, 79.8% of Hawaii's electric generating capacity came from petroleum-fired power plants.[1]

Legislative issues

In 2008, the state legislature passed the Hawaii Solar Roofs Law, which mandates that almost all new homes have solar water heating systems installed.

Proposed coal plants

There are currently no proposals - either active or cancelled - to build coal-fired power plants in Hawaii.

Existing coal plants

Hawaii had one coal-fired generating station in 2005, with 203 MW of capacity - representing 7.8% of the state's total electric generating capacity:[1][7][8]

Plant Name County Owner Year(s) Built Capacity 2007 CO2 Emissions 2006 SO2 Emissions SO2/MW Rank
AES Hawaii Oahu AES 1992 203 MW 1,634,000 tons 921 tons N/A

This one plant represents 7.6% of Hawaii's total CO2 emissions, and 1.5% of the state's total SO2 emissions.[3]

Major coal mines

There are no coal mines in Hawaii.[9]
