The Nord Stream 2 pipeline is on the scrap heap because of the Ukraine crisis. Here’s why that matters

The 1,230-kilometer pipeline was supposed to ferry huge amounts of natural gas directly from Russia to Europe via Germany, and although it has been sitting there, built for more than five months, not a single delivery has passed through it.The project has divided politicians, analysts and Europeans for years, and has been beset by delays, previous Nord Stream 2 was set to add 100 million tons of carbon dioxide into the atmosphere every year, not to mention the inevitable leaks of methane, a greenhouse gas with more than 80 times the planet-warming power of CO2 in the short term.Now Europe — Germany in particular — has an opportunity to use this moment to move away not just from Nord Stream 2 but its growing reliance on fossil gas altogether. Germany is one of few developed nations that opposes nuclear power and is in the process of shutting down its few reactors. Without it, it has become highly dependent on gas, and will need a radical rethink to speed up energy generation from renewables. Considering the environmental concerns around dealing with the radioactive waste that nuclear energy brings, its role in the future energy mix across Europe as a whole has its limitations. A rapid scale-up of renewables — solar, wind and hydropower — offer security in both energy and climate protection. Moving subsidies away from fossil fuels to renewables would be an easy first step.In the short term, Europe can scramble gas from other countries — unlikely enough to replace Russia, but perhaps enough to get by — and deal with the immediate Russian threat.But the forever problem of the climate crisis will keep churning and will ultimately be deadlier and costlier than military confrontation is likely to be.
