Energy Efficiency in Engineering focuses on reducing energy consumption and minimizing greenhouse gas emissions, rather than maximizing energy production.

All of the mentioned measures are commonly used to improve energy efficiency in buildings.

The primary goal of energy conservation is to reduce energy consumption, thereby minimizing energy waste and promoting sustainability.

Natural gas is a fossil fuel and not a renewable energy source.

Energy diversification refers to the process of generating energy from multiple sources, including renewable and non-renewable sources.

Energy efficiency in industrial processes typically leads to reduced energy costs, increased productivity, and improved product quality, but it does not result in increased greenhouse gas emissions.

Energy recycling involves recovering and reusing energy from waste materials, such as heat from industrial processes or waste biomass.

Sustainable engineering practices aim to minimize energy consumption, waste, and pollution, and protect natural resources, rather than maximizing energy consumption.

Energy efficiency refers to the process of reducing energy consumption without compromising on the level of service, while energy conservation involves reducing energy consumption overall.

Increasing the number of vehicles on the road is not an energy efficiency measure, as it leads to increased energy consumption and traffic congestion.

Geothermal energy involves generating energy from the heat of the Earth's interior, typically through the use of geothermal power plants.

Increasing the use of fertilizers is not an energy efficiency measure in agriculture, as it does not directly reduce energy consumption or improve energy efficiency.

Hydropower involves generating energy from the movement of water, typically through the use of hydroelectric power plants.

Increasing the use of fossil fuels is not an energy efficiency measure, as it leads to increased energy consumption and greenhouse gas emissions.

Solar energy involves generating energy from the Sun's rays, typically through the use of solar panels or solar thermal systems.
