Natural gas is often still a backup for alternative energy.

Some folks say that solar power is not that good on the grid since it's hard to store for when the sun isn't shining. Batteries are a bit difficult, but on the grid natural gas is often used as a backup.

Yes, natural gas isn't necessarily evil. It's often used as a backup for solar and wind farms when the sun isn't shining or the wind isn't blowing.

We are using at least less fossil fuels when the sun is shining. Natural gas is often used as a backup fuel and of course people still are burning lots of fossil fuels driving cars, heating homes and using electricity, these days, anyway.

Here in the northwest, hydropower is a good backup to green energy as well and batteries are getting better.
