I think it depends on how it's executed.
On the one hand, yes, building renewables at large scale is more expensive than gas, whilst nuclear is capital intensive (even if cheaper long term). As such, Government level 'grid improvements' are probably not gonna improve peoples standard of life. It's perhaps worth noting that renewables are getting cheaper every year whilst gas is fairly stable however.
On the other hand, I work for a large beverage company. We're working on moving away from at nat gas for thermal energy across our network globally and installing anaerobic digesters at each large plant. At some we can do the combined thermal / electrical thing and eliminate our electricity spend too.
On the one hand, this is good for the environment and gives marketing a good story (they claim that a 100% pricing premium is possible for products in our sector with an eco story in the US). On a more pragmatic level it allows us to generate value from a waste stream, eliminate a global natural gas bill that runs to tens, maybe hundreds of millions worldwide, and even sell the excess methane back into the grid. This is just good business. Even ignoring the soft benefits, any project that offers millions in savings and offers a payback of less than 5 years is worth looking at I'd say. The same can be said for energy recovery, process eficiencies, small scale renewable installations in the correct locations. Personally I'm not that fussed about emissions, but I am very interested in efficiency and cost savings. Eco measures, done properly, help me with this goal.
