"Refuse to use" is the wrong expression, as we are using the technology to solve the problem as in solar, wind, wave, water, etc. It is just that we are refusing to give up on fossil fuels (coal, oil, gas) quickly enough. We should be pushing at the maximum possible speeds to make the transition. For an intermediate time, using gas instead of coal and oil also reduces the CO2 footprint, as gas has a 1/3rd less carbon compared to coal. Which is also a reason, why Diesel cars don't save as much carbon as the fuel consumption suggests, as Diesel fuel is about 10% more carbon-rich than gasoline per litre.
