Fossil fuel heating refers to the use of natural resources like natural gas, oil, and coal to generate heat for residential and commercial spaces. These fuels are burned in furnaces or boilers to produce warmth, making them a common choice for heating systems worldwide. While effective, fossil fuel heating contributes to greenhouse gas emissions, which can impact climate change. As a result, there is a growing interest in alternative heating methods, such as electric heat pumps and solar heating, which aim to reduce reliance on fossil fuels and promote sustainability.
