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

Energy-efficient appliances consume less energy to perform the same tasks, leading to reduced energy consumption.

Nuclear power plants do not utilize renewable energy sources and are not considered renewable energy technology.

Photovoltaics is the process of converting sunlight directly into electricity using semiconductor materials.

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

Wind power is the process of converting the kinetic energy of moving air into electricity.

Biomass is not a renewable energy source that can be used to generate electricity.

Geothermal power is the process of converting the heat from the Earth's interior into electricity.

Incandescent light bulbs are not energy-efficient lighting technology.

Hydropower is the process of converting the kinetic energy of moving water into electricity.

Renewable energy does not produce greenhouse gases, so it does not contribute to increased greenhouse gas emissions.

Fossil fuel power plants generate electricity by burning fossil fuels such as coal, oil, or natural gas.

Tidal energy is not a renewable energy source.

Biomass power plants generate electricity by burning organic materials such as wood, crops, or animal waste.

Energy conservation does not produce greenhouse gases, so it does not contribute to increased greenhouse gas emissions.
