Gas explosion. I really think homes and buildings need to be electric without gas lines within them or under the streets. If a power plant runs on natural gas it can supply the electricity any city needs. Natural gas pipelines among homes and buildings is a really bad idea.
Besides, the future doesn't require pipelines of gas. The future is about alternative energies and they don't pipelines.
