and as the world's population increases and the supply of fossil fuels dwindles, it becomes more expensive to extract what fossil fuels remain from their subterranean sources. Moreover, the burning of fossil fuels, more than just a blight on skylines, creates products that contribute...
Fossil fuels, such as coal, oil and natural gas, are created when organic matter decays and becomes compressed beneath layer upon layer of sand, earth, rock and ocean. Interestingly, the name “fossil fuel” is actually derived from the word “fossil”: the mineralised remains...
Unlike power sources that use fossil fuels, the only by-products from an operating fuel cell are heat and water. To be more technical about it, a hydrogen atom with its one electron, attempts to pass through a fuel cell membrane(膜) to unite with an oxygen atom. The membrane allows ...
It's in fact the burning of what we call "fossil carbon" that creates the imbalance: fossil fuels, coal, oil, natural gas. These substances are all mined. We have to dig them up or drill a well to release them. And this is carbon that was in the atmosphere millions of years ago....

Keep reading to clear up some of the confusion over biofuels and fossil fuels. Biofuel Facts A biofuel is any fuel source that’s made from biological materials. The two most common kinds of biofuels right now are both gasoline alternatives: ethanol and biodiesel. Ethanol is ethyl alcohol ...
The executive chairman of Spanish renewable energy giantIberdrolasaid the process of replacing fossil fuels with electrically powered equivalents, such as electric vehicles or heat pumps, is "absolutely unstoppable." "We are seeing that probably we are in the best moment for electrification," Iberdrola...
Their iron-rich excrement creates the perfect growing conditions for phytoplankton(浮游植物). These creatures may be microscopic, but, taken together, they have a great influence on the planet's atmosphere, absorbing about40% of all CO2 produced, four times the amount absorbed by the Amazon...
Fuel has always powered humankind’s technological advances, from the wood-burning fires first used to cook food to the fossil fuels that propelled the Industrial Revolution and have made modernity possible. But the use of fossil fuels has come under scrutiny in light of their role in climate ...
“Support for supply can come through investment incentives, while demand can be supported through mandates for the use of renewable fuels, as well as by ensuring that the cost of carbon emissions is reflected in fossil fuel pricing.” In addition, it is important for electrical grids, pipelines...
