it is a home that is powered by energy resources
They are a car that uses gas as a source of energy.
efficent
That's means energy. No, 'efficient' means getting the best out of the energy that you are using. Energy in itself can be used efficiently or inefficiently.
A wind turbine has fan-like blades that convert wind energy into electrical energy.
A generator is a device that converts mechanical energy into electricity. It works by spinning a coil of wire within a magnetic field to produce an electric current. The mechanical energy can come from sources like wind, water, or steam.
What are iran's energy sources?
Of course they do. Every PC is different in how it works and how energy efficent it is depending on which make, model and even company you buy from.
That depends on the source. Solar energy is raidaint and counts as renewable, if you could collect radiant energy form naturally occurring sources they would be renewable, in many cases the radiant heater though not renewable in large structures like aircraft hangars are more energy efficent.
Try to use less, and not to waste energy. Some things you can do include walking or using public transportation instead of using a personal car; using modern light bulbs that use less energy; turning light bulbs (or any other device) off when you don't actually use them.
A generator is a device that converts mechanical energy into electrical energy by electromagnetic induction - it "generates" (or creates) electricity.A generator is a mechanical device which converts mechanical energy to electrical energy. Generators may be driven by a broad range of sources; steam turbines, electricity, petrol, or oil, natural gas, wind, and even water (hydroelectric).
