Kudos to the Practical Policy Institute for once again acknowledging that “climate change is definitely real and we need to do better … to encourage rooftop solar and photovoltaic projects on already-urbanized land” (“100% renewable for Oahu is bad law,” Island Voices, Star-Advertiser, Dec. 31).

Their point about maximizing the utility of our scarce land resources among the three primary uses — housing, agriculture and energy— is also correct. Wherever we build, at least two of those three uses must be derived from any project.

An idea whose time has come is agrivoltaics. Solar farm arrays can be raised a little bit higher so that crops requiring different levels of sun exposure can be grown beneath to maximize yields, save water and allow livestock to graze.

I invite anyone reading this to visit www.harc-hspa.com/agrivoltaic.html to see the various benefits and applications of this very exciting program.
