Biofuels are liquid fuels produced from renewable biological sources, including plants and algae. Biofuels offer a solution to one of the challenges of solar, wind, and other alternative energy sources. These energy sources have incredible potential to reduce our dependence on fossil fuels and yield environmental and economic benefits. But many of these sources have a limitation: they can’t replace liquid fuels such as jet fuel, gasoline, and diesel fuel that are critical to our transportation needs. That’s where biofuels could help.
Technology to remove the planet-warming greenhouse gas CO2 from our atmosphere must be urgently ramped up, leading climate experts say in a new report.
Scientists say big cuts in CO2 emissions won't be enough to limit global warming.
Biofuel is any kind of fuel that is directly derived from plant or animal matter, also known as biomass, and produces bioenergy. ‘Bio’ is used to depict the organic nature of this fuel source because it is not produced by a geological process like that of fossil fuels (petroleum and coal).
It's a new hydrogen-diesel hybrid engine affectionately known as "baby number two" that could help to decarbonise some of Australia's heaviest industries.
The test rig is large - it has its own room adjoining a lab and looks at first glance like many other large motors, but beneath its metallic skin could lie game-changing technology.
The Greenland ice sheet, one of the coldest and most remote regions of the world that serves a pivotal role in the Earth's climate, is now clearly feeling significant effects of climate change. Researchers found that central and northern areas of the sheet have recently seen the hottest temperatures in a millennium.
A startup company made aviation history Thursday when it successfully flew the largest ever hydrogen-electric powered aircraft, which could pave the way for less environmentally harmful flights.
Microsoft co-founder turned billionaire philanthropist Bill Gates said he is hopeful that fake meat products will eventually be a "very good" option for consumers even though the share of products in the "meat" market is small.
Scientists at Lawrence Berkeley National Laboratory have developed a novel potential means of alternative refrigeration: ionocaloric cooling. The method involves electrically charged atoms or molecules (ions) changing the melting point of a solid material, much like adding salt to roads before a winter storm changes how ice will form. Their proof-of-principle experiment used salt made with iodine and sodium along with an organic solvent to achieve energy-efficient cooling, according to a recent paper published in the journal Science.
During World War II, the U.S. dropped an atomic bomb over Hiroshima, Japan, wiping out 90% of the city. Last year, researchers say, the ocean heated up an amount equal to the energy of five of those bombs detonating underwater "every second for 24 hours a day for the entire year."
During a visit to a bookstore a few weeks ago, we couldn’t help but stare at a display unit featuring no fewer than ten books telling you how to rid plastics from your daily life. We’re bombarded by information on the topic of marine litter and plastic pollution, but how much do we really know about the problem?
