Energy extraction refers to the process of obtaining usable energy from various sources. This can include fossil fuels like coal, oil, and natural gas, as well as renewable sources such as solar, wind, and hydropower. The goal is to convert these energy sources into forms that can be used for electricity, heating, or powering vehicles. The methods of energy extraction vary depending on the source. For instance, drilling is used to extract oil and gas, while mining is employed for coal. In contrast, renewable energy extraction often involves capturing sunlight with solar panels or harnessing wind through turbines. Each method has its own environmental impacts and efficiency levels.
