Solar 1: panels on fruit stand
Solar 2: panels on/next to greenhouse
Wind Turbines: on top of greenhouse
Biomass: oven inside greenhouse, use waste from farm


Durability: how long will it last
Safety: risk to people
Availability: able to create power all year long
Education: use to explain to high schoolers, good learning opportunity
(+maintenance)
