Energy-efficient technologies primarily focus on reducing energy consumption and minimizing energy waste, rather than increasing energy production.

Energy efficiency standards are designed to establish minimum energy performance requirements for appliances, equipment, and buildings, with the goal of reducing energy consumption and improving energy efficiency.

Energy-efficient windows are designed to minimize heat loss and gain through windows, reducing the energy required for heating and cooling buildings.

Smart thermostats allow users to program and control the temperature of their homes, optimizing energy usage and reducing energy waste.

Incandescent light bulbs are traditional light bulbs that are not energy-efficient, as they consume more energy and produce less light compared to energy-efficient alternatives like LED bulbs.

Energy-efficient lighting systems offer multiple advantages, including reduced energy consumption, increased light output, and longer lifespan of light bulbs.

Variable frequency drives are used in industrial applications to control the speed of electric motors, optimizing energy usage and reducing energy consumption.

Energy audits are conducted to assess the energy performance of buildings, identify areas of energy waste and inefficiencies, and recommend measures to improve energy efficiency.

Idling the engine while parked is an inefficient practice that wastes fuel and increases emissions. Energy-efficient transportation practices aim to reduce fuel consumption and emissions.

Energy-efficient appliances offer multiple benefits, including reduced energy consumption, lower utility bills, and increased comfort and convenience.

Solar panels, wind turbines, and hydroelectric power plants are all examples of energy-efficient technologies used to generate electricity from renewable sources.

Energy-efficient building codes are designed to establish minimum energy performance requirements for new and renovated buildings, with the goal of reducing energy consumption and improving energy efficiency.

Server virtualization, energy-efficient cooling systems, and variable frequency drives are all examples of energy-efficient technologies used in data centers to reduce energy consumption.

Energy-efficient lighting systems in commercial buildings offer multiple benefits, including reduced energy consumption, lower utility bills, and improved employee productivity due to better lighting conditions.

Leaving fields fallow for extended periods is not an energy-efficient practice in agriculture, as it can lead to soil erosion and loss of soil fertility.
