A bunch of new non-fossil fuel power plants, plus additions to the grid is going to cost a lot of money. Storage is only a "probably" rather than a definitely, it depends on what alternative you go to, but if you go to heavy reliance on solar or wind, you are going to need a lot of storage (or duplication with other types of power plants, or an acceptance of blackouts as being the norm). Other costs will also certainly have to be paid, but there is no way to be specific about it, unless you can tell me specifically what you will do in order to decrease CO2 emissions. Do it one way and you get one type of cost, another way and you get another cost. Your the one trying to make a chance happen, but despite that I've been far more specific than you have. How about you answer some questions instead, how are you going to slash CO2 emissions that much? How are you going to do so and still keep increasing energy production? How are you going to do so and get reliable 24/7 power? How are you going to do so without taking a very long time? How are you going to do so without pushing heavy industry to other countries? How are you going to get other countries, that are poorer than us, to slow their development so they can reduce CO2? Most of the rest of the world has signed on. The rest of the world has not signed on to cutting their CO2 emissions by 80%. And what they have signed on to, they have failed to actually do. Signing is easy, its doing that's the hard part. China and India won't because we won't... China and India won't actually makes such a reduction, because they can't without condemning their people to poverty and probably creating political instability. At least they have been honest enough not to falsely sign on to something they have no intention of actually doing. As for CO2 I already answered the question in general terms. More specific terms where not possible, partially because you didn't provide any information (how much extra CO2 over how long of time frame), and partially because climate is to complex to accurately predict in detail no matter how much information one is given.
