Energy conservation aims to reduce energy consumption and improve efficiency, leading to lower costs and reduced environmental impact.

Natural gas is a fossil fuel and not a renewable energy source, unlike solar, wind, and hydropower.

Energy efficiency refers to using less energy to perform the same task or achieve the same outcome.

Leaving lights on all day is not an energy-efficient practice, as it wastes energy unnecessarily.

Renewable energy sources, such as solar and wind, do not produce greenhouse gases or other pollutants, making them environmentally friendly.

Driving a gasoline-powered car is not a sustainable energy practice, as it contributes to greenhouse gas emissions.

Energy sustainability refers to the ability of a system to meet current energy needs without compromising the ability of future generations to meet their own energy needs.

Installing solar panels on the roof is not a passive solar design strategy, as it requires active components to generate electricity.

Renewable energy sources, such as solar and wind, are intermittent and cannot be relied upon to generate electricity consistently.

Energy conservation aims to reduce energy consumption, not increase it.

Renewable energy refers to energy generated from sources that are naturally replenished, such as solar, wind, and hydropower.

Nuclear power plants do not use renewable energy sources, as they rely on uranium, which is a finite resource.

Sustainable energy practices aim to reduce environmental impact and protect natural resources for future generations.

Coal is a fossil fuel and not a sustainable energy source, as it contributes to greenhouse gas emissions and air pollution.

Energy independence refers to the ability of a system to generate its own energy needs without relying on external sources.
