Have energy saving options for people who don't have central air/heating.
I live in an apartment where we have heating units. Each time my energy bill spikes, all I hear is set your thermostat on sixty something degrees, but I don't have one. I even turn off the heating unit at night and use a space heater in my bedroom all night with the hope of saving energy. There certainly must be a way, I mean, you guys don't only provide energy to people with thermostat.
