But... how would the corporations make money?

The truth about renewable energy: Inexpensive, reliable, and inexhaustible
Renewable energy actually reduces electricity prices for businesses and consumers. 
Infrastructure to connect renewable energy is a great investment. 
Integrating variable renewable resources is easier and cheaper than we thought.
Why has integrating so much wind so fast been relatively painless? 
Geographic diversity: The wind blows at different times in different places across MISO’s 12-state footprint, smoothing out the variation at any single location. 
Better forecasting tools make it easier to accurately predict wind-turbine output. 
Transmission expansions and upgrades are being approved and constructed, giving operators greater flexibility to manage all resources and consumers more choices and competition. 
Grid operators around the country and the globe are gaining experience and learning from each other as they successfully integrate ever larger amounts of renewable energy into their systems.
America has far more than enough renewable energy resources to meet its entire electric demand.

Not to mention the pile of shredded feathers

As birds are blenderized out of the air...

Wind turbines continue to multiply the world over. But as they grow bigger and bigger, the number of dangerous accidents is climbing. How safe is wind energy?

[snip]
After the industry's recent boom years, wind power providers and experts are now concerned. The facilities may not be as reliable and durable as producers claim. Indeed, with thousands of mishaps, breakdowns and accidents having been reported in recent years, the difficulties seem to be mounting. Gearboxes hiding inside the casings perched on top of the towering masts have short shelf lives, often crapping out before even five years is up. In some cases, fractures form along the rotors, or even in the foundation, after only limited operation. Short circuits or overheated propellers have been known to cause fires. All this despite manufacturers' promises that the turbines would last at least 20 years.
Actually bird deaths are being reduced as the machinery gets better. But don't get me started on hang gliders and remote control airplanes....
