Bicycle
Native Americans used horses as their most efficient form of transportation.

Fossil fuels like gasoline and diesel are the most concentrated form of energy, holding a high amount of energy per unit of volume or weight. This makes them efficient for transportation and industrial uses.
Yes, it is generally true that a bicycle is the most efficient mode of transportation for short distances due to its low energy consumption and minimal environmental impact compared to other modes of transportation like cars or buses.
Car
planes crashOn a more serious note, air transportation is the leastfuel-efficient form of transportation, using the most fuel per mass/distance of any modern transport. It also uses the most expensive form of vehicle in the transportation area (as measured by capacity/$ )
Walking or going on a bicycle, if it is reasonably close. Otherwise, a school bus or public transportation is more energy efficient, because a bus takes many people at once.
LEDs are the most energy-efficient lights as of 2016.
Lipids, such as fats and oils, are highly efficient at storing energy because they have a high energy density. Each gram of lipid contains more energy than carbohydrates or proteins. This makes lipids an excellent form of long-term energy storage in the body.
Any dishwasher that is Energy Star Rated is energy efficient.

Most modern fridges are designed to be energy-efficient, meeting strict energy efficiency standards. However, older fridges may not be as efficient, leading to higher energy consumption. It's important to look for the Energy Star label when purchasing a new fridge to ensure it is energy-efficient.
