(The word in Greek means “water former” because hydrogen creates water when burned.) When used alongside other technologies, such as renewable power and biofuels, hydrogen has the potential to decarbonize a whole host of industries, including some of the biggest emitters of greenhouse gases. ...
Fixed nitrogen is taken up by plants, which are eaten by animals, which eat other animals, which die and decompose and release nitrogen back into the ecosystem to be worked on by bacteria or plants. This is the cycle of a nitrogen atom on Earth, and its journey starts either very ...
It was bad enough when we found out this past January that the fossil fuel industry had more than enough evidence as early as 1954 to understand the impact of greenhouse gas emissions on the climate. But then word came today, with the release of internal documents, that Big Oil lobbied ag...
Traditional energy sources, like coal and oil, are finite and when burned, release carbon in the form of carbon dioxide and methane — two greenhouse gases that significantly contribute to the acceleration of global climate change. Renewable energy, on the other hand, either does not emit carbon...
and that has seemed to be coal. Coal has such a large beneficial impact on our economy, from mining to producing energy the coal industry creates millions of jobs and generates millions of dollars for our economy. Coal does have some negative impacts on our environment but there are steps be...
However, when fossil fuels are burned, they release greenhouse gases (GHGs) like carbon dioxide (C02), methane (CH4) and nitrous oxide (N20) into the atmosphere. When GHGs build up in the atmosphere, they trap the sun’s radiation and prevent it from being released into space, warming Ear...
In an age when waste today means a lack tomorrow, making use of every available resource becomes more and more important. As coal is being used in greater and greater amounts to produce electricity, larger amounts of ash, by-product of coal, are produced. When coal is burned in a boiler...
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....
Alternative energy encompasses energy sources that are not based on fossil fuels. These sources are typically characterized by their renewable nature and minimal environmental impact. Unlike fossil fuels, which release significant greenhouse gases and pollutants when burned, alternative energy sources offer ...
