Access to energy and in particular access to electricity is an indispensable condition for a country's economic and sanitary development.
Although the worldwide energy consumption has almost doubled since 1970, it hasn't increased much in poorer countries. To this day approximately 2 billion people can't rely on having access to enough energy for living under reasonable conditions and 1.6 billion people don't have access to electricity at all. Consequences for environment and sanitary conditions are enormous.
Renewable energies like the wind turbine might be a solution: "A wind turbine converts kinetic energy in the form of wind into electrical energy"
