Whirlygigs and solar panels are just infill to meet a local increase in demand without the expense of stringing new transmission lines and stationary generation. The cost is never seen by the power companies but the benefits are abundant.Here's the problem with wind. Take your standard 2MW turbine. Depending on the environment they're in they have a shelf life of 20-25 years. Now, in order to meet just the annual increase in demand for power, you'd have to cover an area about the size of Great Britain in wind farms every year. After 25-30 years you'd cover a land mass almost equal to the size of Russia. And that's where the problem really begins. First, this doesn't take into account replacing the fossil fuel power plants, this is only to meet the annual increased demand. Secondly, after 20-25 years you'd have to start building twice as many turbines every year, half to meet the annual increased demand for power and the other half to replace the old, worn out turbines. Plus, you still need oil to lubricate them and you can't use vegetable oil. As well they require the same batteries for back up as the ones that like to spontaneously combust.
Solar is a better option but only if you get enough annual solar radiance to make it viable. They benefit at least is you can use molten salt batteries.
Here's the reality in Canada. Quebec and Ontario could supply the entire country with almost 100% emissions-free power. (As it is the country as a whole pumps out 3% of the world's annual total power while doing it 82-83% emissions-free.) But in order for that to be feasible in the near future, people need to quit shitting their pants over nuclear power so we can build micro reactors.
