For most countries around the world, sourcing energy entirely from wind, solar, geothermal, and hydropower by 2050 would reduce their energy needs and costs, improve air quality, and help slow climate change, according to a study in Environmental Science & Technology.
We currently emit a lot so the choice is: emit less with renewables or keep emitting but capture the carbon
Since renewables are much cheaper we reduce emissions much faster then going with carbon capture. That might be a good idea down the line, but currently 80% of our energy comes from fossil fuels, so down the line is probably decades.
