Unless you speak of the supernatural, all resources are natural. Humans and our desire for energy is also natural. Ecosystem disruption is also natural since we are natural also. The only question is sustainability. More solar farms in the desert disrupts an ecosystem but not to the extent of causing species to die off or a food chain collapse that affects humans. More nuclear plants use more fissile material but at such low volume and extraction cost it's negligible. If you take a walk through the woods you'll step on grass and insects and cause damage. It's unnatural to live without interacting and harming flora and fauna and there are plenty of energy sources to sustain humans for millenia to come.
