Critical food shortages and growing demand for bio-fuels and hydro-electricity due to high fossil fuel prices rank among the greatest threats today to the preservation of precious wetlands worldwide as farmers and developers look for new areas for agriculture, energy crop plantations and hydro dams.

As fossil fuel emissions continue to climb, reducing the amount of sunlight hitting the Earth would definitely have a cooling effect on surface temperatures.

Methanol fuel cells are an efficient and sustainable alternative to fossil fuels, but they are still not economically viable Nevertheless, for his PhD, University of the Basque Country (UPV/EHU) research chemist, José E. Barranco, has developed new materials that enable the manufacture of cheaper and more efficient methanol fuel cells.

Over millions of years carbon dioxide levels in the atmosphere have been moderated by a finely-tuned natural feedback system— a system that human emissions have recently overwhelmed. A joint University of Hawaii / Carnegie Institution study published in the advance online edition of Nature Geoscience links the pre-human stability to connections between carbon dioxide in the atmosphere and the breakdown of minerals in the Earth’s crust.

Nuclear energy production must increase by more than 10 percent each year from 2010 to 2050 to meet all future energy demands and replace fossil fuels, but this is an unsustainable prospect.

Scientist John Incardona will tell a scientific detective story that uncovers a previously unrecognized threat to human health from a ubiquitous class of air pollutants.

Let's say a fuel derived from biomass produces too much soot when it's burned in a combustion chamber designed for fossil fuels.

Research projects by the University of Bath into cleaner alternatives to fossil fuels have been chosen to be showcased at a prestigious scientific festival.

A team of Carnegie Mellon University researchers report that the choices U.S. officials make today could limit how the nation’s future energy needs are met and could cost consumers billions in idle power plants and associated infrastructure systems.

A 4-year study of mercury in crude oil refined in the United States has found that, of the two major sources of U.S. fossil energy mined coal and crude oil crude oil contains much less toxic mercury, on average, than coal. The study is scheduled for publication in the July 1 issue of ACS Environmental Science & Technology, a semi-monthly journal.

Natural disasters such as Hurricane Katrina and mechanical failures at pumping stations have highlighted the limited availability and unstable supply of fossil fuels.

Carnegie Mellon University's David S. Sholl is working to identify new materials that would help make hydrogen more stable and cost-efficient than fossil fuels. Increased concern about global warming and a need to conserve natural fuel sources prompted Carnegie Mellon researchers to find new, lightweight, low-cost hydrogen-storage materials.
