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

Energy efficiency measures aim to reduce the amount of energy required to perform a specific task or achieve a desired outcome.

Energy efficiency measures are designed to reduce energy consumption, not increase it.

Solar energy is the most abundant renewable energy source, as it is derived from the sun's radiation.

China is the global leader in installed solar PV capacity, with over 300 gigawatts (GW) of installed capacity.

Wind power is the term used to describe the process of generating electricity from the kinetic energy of wind.

Nuclear power plants do not use renewable energy sources, as they rely on uranium or plutonium for fuel.

Renewable energy sources do not produce greenhouse gases or other air pollutants, which helps to reduce air pollution.

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

Hydropower is the term used to describe the process of generating electricity from the movement of water.

Renewable energy sources do not deplete natural resources, as they are derived from naturally occurring processes.

Geothermal power is the term used to describe the process of generating electricity from the heat of the Earth's interior.

Using renewable energy sources is not an energy efficiency measure, as it involves generating energy rather than reducing energy consumption.

Solar power is the term used to describe the process of generating electricity from the sun's radiation.

Energy efficiency measures are designed to reduce energy consumption, not increase it.
