Energy diversity in a carbon constrained world mustn't embrace fracked natural gas. Methane leaks cause warming, and burning it still makes unacceptable levels

Energy diversity in a carbon constrained world mustn't embrace fracked natural gas. Methane leaks cause warming, and burning it still makes unacceptable levels of CO2. Diversity is valuable but we should install district heating systems and hydrogen pipelines and whatnot, not fracked gas plants.
