  • Charging Solar Lights Without Sun: Expert Insights
    Mark explains, "You can charge solar lights without direct sunlight, but it's less efficient." Artificial light works but may degrade batteries over time. Charging costs are minimal with LED lights, yet natural sunlight remains the best option for optimal performance.
  • Efficient Winter Ventilation: Keep Air Fresh Without High Energy Bills
    Mark suggests using a heat recovery ventilator (HRV) to retain heat while ventilating. He recommends "window trickle vents, air purifiers with HEPA filters, and houseplants" for better air quality. To avoid dry air, use a humidifier or place water bowls near heat sources. These strategies ensure fresh air without high energy bills.
