Cause it saves energy, using the sun to power things instead of using normal electricity
An electric meter or energy meter is used now a days.
In India we have 300 sunny days - but we ignore this renewable energy to produce electricity.
The cotyledon
A windmill captures the energy of the wind, which is free, and uses the energy for something else. In the olden days it was used to grind grain into flour, or to pump water up a hill. It is now being used to generate electricity, without any harmful emissions of carbon dioxide.

First you have to convert whatever energy source you are using (gasoline, diesel, coal, electricity, elastic bands) into mechanical energy. This would probably be with an internal combustion engine or an electric motor, in past days with a steam engine. Then you couple the engine to the moving parts with a transmission.
The second source of energy for your body, after Carbohydrates (straches, sugars), are the Lipids (fats: oil, butter).Lipids are used for long term energy storage (days to years)
Have you heard of CO2... And BTW it's a nearly infinite source of energy.

You can get mechanical energy through an electric motor, or thermal energy through a resistance heating element. You can also breakdown an electrolyte by passing a current through it, and you can produce microwave energy in a magnetron, or acoustic energy through loudspeakers.
