In discussions about building a generator using renewable energy, participants highlight the importance of local resources, noting that options like solar, wind, and biogas can be viable depending on the area. While solar panels are recognized as expensive, they are considered a low-maintenance option when paired with battery storage. Methane digesters are suggested as a reliable choice due to their lower intermittency compared to other renewable sources. Hydroelectric energy is also mentioned as a feasible option if near water bodies. However, developing a complete system within a $1000 budget poses challenges, leading some to suggest purchasing a dual fuel generator that can run on gasoline or propane, with modifications to utilize methane or alcohol. Caution is advised regarding the quality of biogas, as it may contain harmful substances for engines.
