LEDs are the most energy-efficient lights as of 2016.
LED light bulbs are the most energy-efficient option for your home.
LED light bulbs are the most energy-efficient for home use.
Bread and carbohydrates are the main sorce of energy
Compact fluorescent light bulbs are pretty energy efficient and are energy star rated.

Light emitting diodes (LEDs) are considered the most efficient light source in terms of lumens per watt. They can produce significantly more lumens per watt compared to traditional incandescent or fluorescent bulbs, making them an energy-efficient lighting option for various applications.

Wind energy is one of the most eco friendly energy source but is not as efficient as others
The most energy efficient lighing is florescent lighting; it takes less power and energy to turn on. CFL lightbulbs are also very energy efficient and would save a lot of money. They will have an energy saver sign on the box if you are not sure. A fixture that has an energy star approved logo on the item would be the most efficient and use the least amount of energy possible. Also using energy efficient light bulbs will improve the efficiency.
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
Not really because the intense gravity field prevents most of the energy escaping.
Light bulbs in order of the least to most energy efficient : incandescent, halogen, fluorescent, LED. For home owners, most reasonable is the CFL lightbulb, which is cheaper and longer lasting than the LED.
