Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms. The age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years. Fossil fuels contain high percentages of carbon and include coal, petroleum, and natural gas. They range from volatile materials with low carbon:hydrogen ratios like methane, to liquid petroleum to nonvolatile materials composed of almost pure carbon, like anthracite coal. Methane can be found in hydrocarbon fields, alone, associated with oil, or in the form of methane clathrates. Fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the Earth's crust over millions of years. This biogenic theory was first introduced by Georg Agricola in 1556 and later by Mikhail Lomonosov in the 18th century.
According to a recently publicized rapport by the Department of Energy’s National Renewable Energy Laboratory (NREL), renewable energy sources could account for as much as 80% of the US’s electricity demand by 2050. The rapport signals the various difficulties that need to be overcome to reach this goal, and note that while 80% might be very challenging [...]
I’ve been receiving questions from you people for years now – and really, this made me happy, because it says that people want to learn and understand more. But I’ve been answering them individually, and now, I’m thinking it would be better to post the answers on the website, so more people can read them. [...]
As fossil fuel resources significantly diminish every year, the world gets ever tumultuous and panic slowly begins to settle moment by moment. Luckily, suitable energy is a topic which gets a lot of attention nowadays, although not nearly as publicized as it should, seeing how the general public is still at a low awareness level. [...]
