There are things to like about the two proposals to build wind farms in the ocean waters off Oahu — and maybe some things not to like — so clearly, more study is needed.

On the “like” side: the farms together would supply about 800 megawatts of renewable power, the same amount Hawaiian Electric Co. says it needs to reach the state’s goal of 100 percent power generation from renewal energy. Also, they would be private enterprises, presumably using their own money for capital costs; far offshore, so for the most part not an eyesore; and attract fish, which would be great for fishermen and consumers, if they are allowed to access the bounty.

On the possible negative side: the effects on marine life; whether subsidies might be involved; the degree of visual blight they might pose; and the impact their cables might have on the seabeds.
