Look at the world's total energy production sources and you'll realize wind and solar will never be able to fulfill our needs.

They need a ton of land and the technologies can only improve so much. Wind especially is way way less efficient on land coverage than any other energy production method.

In the future we'll need more land for agriculture, so our energy production methods better take that into account also. We'll keep using coal and gas and oil for producing energy even if we increase "green" energy production the fuels are still needed for emergencies and times when there's no wind/sun or when there's emergent demand.

China is now actually increasing its coal mining operations. And the oil reserves we have can last us for centuries even with current production.

Surely climate change is a concern, but it doesn't look like there will be a slowdown in gas consumption.
