1. The Physics Objection (Thermodynamics)

• Energy cannot be renewed: The First Law of Thermodynamics states that energy cannot be created or destroyed.
• Energy degrades: The Second Law states that when you use energy, it degrades into useless waste heat.
• Strictly speaking: You never “renew” energy; you only transform it from a useful state to an un-useful state.

2. The Material Objection (Infrastructure)

• Equipment wears out: Solar panels, wind turbines, and batteries are not renewable.
• Mining limits: Building them requires massive amounts of non-renewable materials like steel, concrete, lithium, and rare earth metals.
• Waste problem: Spent wind turbine blades and old solar panels end up in landfills, making the system unsustainable over time.

3. The Power Density Objection (Land Use)

• Dilute sources: Sunlight and wind are very weak and spread out compared to fossil fuels or nuclear energy.
• Massive footprint: You need huge amounts of land to capture enough power, which can destroy local ecosystems and forests.
• Ecological cost: Destroying nature to build “green” power plants contradicts the idea of being truly renewable.

Alternative Terms to Use Instead

• Flow energy: Capturing energy from natural, ongoing flows (like wind or currents).
• Income energy: Using energy that arrives daily (like sunlight), rather than drawing down “capital” energy stored underground (like coal).
• Alternative energy: Power sources that simply replace traditional fossil fuels.

Until we start using the correct terminology, confusion and incorrect information will be acceptable.
