Coal, produced over millions of years, is a finite and non-renewable resource on a human time scale. A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. [1] An example is carbon-based fossil fuels.
National Fuel Gas Company (NYSE: NFG) is a diversified energy company with $6.2 billion in assets distributed among the following five operating segments: Exploration and Production (Seneca Resources Company, LLC), Pipeline and Storage (National Fuel Gas Supply Corporation and Empire Pipeline, Inc.), Gathering (National Fuel Gas Midstream Company, LLC), Utility (National Fuel Gas Distribution ...
To become a zero-carbon city, renewable energy must supersede other non-renewable energy sources and become the sole source of energy, so a zero-carbon city is a renewable-energy-economy city. Transitioning to a zero carbon city means examining the generation of power sources, such as renewable electricity and decarbonising electricity production.
Alternative fuels, also known as non-conventional and advanced fuels, [1] are fuels derived from sources other than petroleum. [2] Alternative fuels include gaseous fossil fuels like propane, natural gas, methane, and ammonia; biofuels like biodiesel, bioalcohol, and refuse-derived fuel; and other renewable fuels like hydrogen and electricity.

The environmental dimension of sustainability includes greenhouse gas emissions, impacts on biodiversity and ecosystems, hazardous waste and toxic emissions, [7] water consumption, [9] and depletion of non-renewable resources. [6] Energy sources with low environmental impact are sometimes called green energy or clean energy. The economic ...

The production of biofuels can be very energy intensive, which, if generated from non-renewable sources, can heavily mitigate the benefits gained through biofuel use. A solution proposed to solve this issue is to supply biofuel production facilities with excess nuclear energy, which can supplement the power provided by fossil fuels. [111]
The goal of such assessments is to cover the full life of the source, from material and fuel mining through construction to operation and waste management. In 2014, the Intergovernmental Panel on Climate Change harmonized the carbon dioxide equivalent (CO 2 e) findings of the major electricity generating sources in use worldwide.
