We had 24 hours where the local temp was below -1 F, and reached -20F before wind chill. My solar more than offset the energy needs all of my electric usage, including the needs of my geothermal heat pump over the 24 hour period. So I heated and ran the electric in my house on the coldest day of the year without purchasing or paying for utilities.
Yeah. renewables make sense.
