Energy is required in many aspects of human society. It powers and is used in both economic and development. Energy demand significantly during the Industrial Revolution, when the majority of energy supply was from sources such as coal, gas and . While this was efficient at dramatically increasing the economy in the Western world, the natural has suffered many consequences as a result. Exploitation of fossil fuels has led to land degradation, loss of , and water and air pollution.
Emissions from burning fossil fuels, such as carbon dioxide, have led to an enhanced effect, which in turn has led to anthropogenic . In recent years, there has been a significant demand for more sustainable energy production, particularly through energy sources. This includes solar, wind and power (HEP). However, such renewables may not be completely green - for example, for HEP a valley needs to be , destroying the existing habitat, while the concrete used in the dam construction generates carbon dioxide. Space is also taken up by solar panels, and the large concrete pads needed for wind , and some people find them a blot on the landscape. We also need to produce and dispose of used equipment, requiring energy and precious resources, and the extra connections to wind and solar farms increases the risk of accidental releases of SF6, the world's most potent greenhouse gas into the atmosphere.
Other sources of energy include power, although the sustainability of this source is often contested due to radioactive waste and the risk associated with production.
