Fossil fuels are carbon compounds formed from the remains of prehistoric organisms, such as coal, oil and natural gas. They are non-renewable resources that provide heat, power and electricity, but also cause environmental damage and climate change.
There are a few more fuels that can be created using hydrogen. Formic acid for example can be made by reacting the hydrogen with CO 2. Formic acid combined with CO 2 can form isobutanol. [15] Methanol can be made from a chemical reaction of a carbon-dioxide molecule with three hydrogen molecules to produce methanol and water.
Greenhouse gases are the gases in the atmosphere that absorb and emit infrared radiation, warming the Earth's surface. Learn about the five most abundant greenhouse gases, their natural and human sources, and their impact on climate change.
Gasification is a renewable energy technology that produces syngas (synthesis gas) from biomass or fossil fuels at high temperatures. Learn about the history, chemistry, types and applications of gasification, as well as its advantages and challenges.
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.

Net zero emissions is the state where human-caused greenhouse gas emissions and removals are balanced, aiming to stop global warming. Learn about the scientific justification, the terminology and the global progress of net zero pledges and legislation.
Learn about the definition, history, types and applications of biodegradable plastics, which can be decomposed by living organisms. Find out how biodegradable plastics differ from bioplastics and compostable plastics, and what challenges they face in the market.
The chart at right attributes anthropogenic greenhouse gas emissions to eight main economic sectors, of which the largest contributors are power stations (many of which burn coal or other fossil fuels), industrial processes, transportation fuels (generally fossil fuels), and agricultural by-products (mainly methane from enteric fermentation and ...
