Episode notes
Stay Grid-Tied As A Practical Net-Zero Approach
- Stay grid-tied while using solar and batteries unless you can reliably produce year-round energy; view grid as seasonal backup.
- Design systems so annual production exceeds consumption, even if monthly balance varies.
Reduce Solar Needs By Improving Efficiency
- Optimize inside energy use first to reduce solar panel needs by adopting efficient appliances like induction cooktops and heat pump water heaters.
- Coordinate systems so excess solar powers an EV and appliances only charge when solar is available.
Make Systems Work Together To Save Energy
- Combine complementary systems (geothermal + de-superheater + heat pump water heater) so waste heat preheats water and cuts energy costs.
- Look for system interactions that reduce operational loads and deliver immediate savings.
