The Guardian: Natural gas killed coal – now renewables and batteries are taking over

Similarly, another 2014 study found that based on the latest estimates of methane leakage rates from natural gas drilling, replacing coal with natural gas provides little in the way of climate benefits. Though it’s been touted as a ‘bridge fuel’ to span the gap between coal and renewables, this research suggests natural gas isn’t significantly better than coal in terms of global warming effects, and thus may not be suitable for that purpose. The ‘bridge’ doesn’t appear to achieve its goal of steadily cutting our greenhouse gas emissions. [...]

The redundancy and potential replacement of natural gas with cleaner alternatives extends far beyond these examples. Most electrical service providers in California are now required to develop integrated resource plans. These are electric grid planning documents that outline how the utilities will meet a number of California’s goals, including a 40% reduction in carbon pollution below 1990 levels and 50% electricity production from renewable sources by 2030. Meeting these goals will require replacing non-critical natural gas plants with renewable power. [...]

Fortunately, rapidly falling costs are already making renewables and battery storage cost-competitive with natural gas, and cheaper than coal. If we’re going to succeed in avoiding the most dangerous climate change consequences, that transition away from all fossil fuels and towards clean energy can’t happen soon enough.
