Every day, I’m scouring the Internet for land use and environmental news from around the state and around the world that mean something for us here in Hawaii. Today’s best: hydroelectric power, noisy coqui frogs and a new take on preserving historic buildings.

• Sustainability, one step at a time: A new Kauai hydroelectric plant will power 75 homes for 100 years.
• Fearful after a single noisy coqui frog was found in Manoa, more than 100 residents attended a Department of Agriculture meeting Monday to learn more.
• The Gas Company, General Motors today announced a partnership that seeks to bring a pilot fuel cell project to Hawaii by 2015.
• A new Japanese study shows a steep drop in Pacific bluefin tuna due to overfishing. Young fish, less than one or two years old, have been increasingly targeted.
• The New York Times asks: Should historic structures be replaced by taller buildings to maximize living and working space? A subset of the preservation vs. growth debate.
