To achieve a near-zero energy home, what must be the strategy regarding energy generation?

To achieve a near-zero energy home, the primary strategy revolves around generating most of the energy on-site, which is key to maximizing energy efficiency and reducing dependence on external sources. This approach typically includes the integration of renewable energy technologies such as solar panels, wind turbines, or geothermal systems that work in tandem with energy-efficient building practices to minimize energy consumption.

Generating energy on-site allows homeowners to take advantage of the free and renewable resources available, significantly lowering their energy bills and environmental impact. While it's common for such homes to still draw some energy from the grid, the goal is to produce a substantial amount of their own energy to offset consumption. This not only supports sustainability efforts but also provides resilience against energy price fluctuations and potential outages.

Creating a scenario where a home produces excessive energy to sell back to the grid could be an aspect of energy generation but does not align strictly with the near-zero energy home concept, which focuses more on self-sufficiency. Relying on traditional energy sources contradicts the intent of such homes, which aim to use clean and renewable energy instead.
