technologies — was driven by policies in nations that increasingly require such power worldwide. The

led investments but, surprisingly, developing nations spent more on renewable energy utility projects, $72
billion, than developed ones, at $70 billion.

Showcase Frankfurt Wind Stock City Windmills: (CYW.F)

City Windmills © was founded in early 2010 and has carried along its idea of building an efficient,
enduring and cheap windmill, adapted for home use, for industrial level use and for larger sized wind
farms. With City Windmills © and the low cost of production per kWh, any home can afford electricity at
grid parity costs.

Several steps of developments allowed the City Windmill © system to evolve from producing energy at
0, 12 € (0, 14 US$) per kWh, then at 0, 09 € (0, 11 US$) per kWh and finally at 0,065 € (0, 08 US$) per
kWh. This production cost, while amortizing the price of a City Windmill © over a period of 20 years (as
for other power producing plants), is competitive with every other energy source. And this is achieved
without any subsidies. In an unsubsidized environment, the payback can be as short as 4.5 years.

The company is targeting the $20 Billion outdoor advertising industry with a new concept in green outdoor
advertising, combining clean energy technology and advertising.
