Availability is a problem. Right now we're mainly backing up renewables with fossil plants.
Most people really aren't getting what climate scientists are saying these days, which is that we have to cut emissions drastically in the very near future to avoid disaster. If we exceed +2C, or possibly even +1.5C, positive feedbacks will take the planet several degrees further even with no more emissions from us. Right now we're at +0.8C. Every ton of CO2 we emit takes 30 years to have its full effect on the temperature, considering direct effects alone, so we've got another 30 years of warming locked in already.
+4C or so might not sound like much but judging by geological history, the effects would include an enormous reduction in the amount of food we're able to produce.
