You can also slow boil a lobster without causing them to react.
The trick is to react soon enough that the change is minor without over reacting and that's hard. I would propose a ~1% carbon fuel tax which funds wind farms which are then sold on the open market. You end up with a huge change at a small cost.
Option 2, create an semi independent government agency like the post office which takes 1 billion and builds wind / solar / hydro power plants. Use the "profit" of electricity sold to build more power plants and let exponential growth take off. This depends on the expected rate of return and could be accelerated with some debt financing.
In 20 years we may find it was pointless but we will have built infrastructure which is useful. Compared to a 2,980 billion dollar annual federal budget you can get a lot done with a change that's hard for most people to notice.
