As high power density devices, fuel cells can convert chemical energy directly into electric power very efficiently and environmentally friendly. Solid oxide fuel cells (SOFCs), based on an oxide ion conducting electrolyte, have several advantages over other types of fuel cells, including relatively inexpensive material costs, low sensitivity to impurities in the fuel, and high overall efficiency.
A University of Colorado Boulder team has developed a radically new technique that uses the power of sunlight to efficiently split water into its components of hydrogen and oxygen, paving the way for the broad use of hydrogen as a clean, green fuel.
Patricia C. Donohue, MCCC President, said the solar farm moves MCCC forward on many fronts. “The solar farm will save critical dollars and enable us to restore to our budget many cuts in programs and services we have made over the past two years. It also helps us fulfill our sustainability goals. We have committed to the American College & University Presidents’ Climate Commitment (ACUPCC) with the goal of achieving carbon neutrality.”
Their research shows that the strength of radio signals on the ground is a reliable indicator of temperature change above. Prof. Price and his team used simple radio antennae on the ground to measure radio waves broadcast by navigational transmitters around the globe, then compared information on the strength of these radio signals with data on temperature fluctuations in the upper atmosphere.
For those scientists, researchers and sustainability innovators wanting to know more about the status of hydrogen today, read the two following AAAS releases below. We need to learn much more about discoveries such as these. Congratulations to all who worked on these projects.
A group of organisms that play a wide variety of crucial roles in our global ecosystems is plants. What role do plants play in helping to regulate climate change and how will they fare in future times? A new series of articles in a Special Issue on Global Biological Change in the American Journal of Botany expands our view on how global changes affect and are affected by plants and offers new ideas to stimulate and advance new collaborative research.
Guest Post: Sustainably Sourced Materials & Doing Your Bit for the Environment During Your Next Building Project
When planning your next building project, think about the materials you’re going to use and how you’re going to recycle and reuse any materials you have left over when you’ve finished your project.
“Thanks to this project, we will be able to supply electricity for the next 20 years and generate important saving to the counties, which currently need the money to restore their finances, improve public services and continue working on security issues in Monterrey,” stated Carlos Jinich, general manager, Comexhidro.
They describe technology that would react the CO2 with water or other liquids and, with further processing, produce a flow of electrons that make up electric current. It could produce about 1,570 billion kilowatts of additional electricity annually if used to harvest CO2 from power plants, industry and residences. That’s about 400 times the annual electrical output of the Hoover Dam.
Having passed a national climate change law in 2012, the Mexican government is turning to an innovative green home loan program to reduce energy consumption and lower the housing sector’s direct and indirect contributions to carbon and greenhouse gas (GHG) emissions. The Eco House program offers new home buyers housing with energy and emissions-saving features, such as roof insulation and solar water heating, at the same cost as conventionally built affordable housing.
According to study, inaction will lead to ‘major setback’ in economic development and food security for the poorest people in Ghana, Burkina Faso and other countries in West Africa
California is known for alternative energy enthusiasm and dedication to energy usage reductions. As part of that, back in 2007, the state launched a $3.3 billion effort to install 3,000 MW of new solar capacity over the next decade. California is one of the US states in which the use of solar energy is encouraged most, and this encouragement (because of the California Solar Initiative) has been so successful that a record-breaking 391 MW of solar panels were installed in California…
The study, “Increase in forest water-use efficiency as atmospheric carbon dioxide concentrations rise,” was published on-line today in the journal Nature. Dave Hollinger, a plant physiologist with the U.S. Forest Service’s Northern Research Station, is a co-author with lead author Trevor Keenan of Harvard University and colleagues from The Ohio State University, Indiana University, and the Institute of Meteorology and Climate in Germany.

Ascent Solar to Build Chinese Manufacturing Plant with Joint Venture Funding from the Suqian Government
Colorado-based Ascent Solar Technologies, a manufacturer of flexible thin-film photovoltaic modules, announced today the signing of an agreement for the establishment of a joint venture with the Government of the Municipal City of Suqian in Jiangsu Province, China. The agreement covers a three-phase project over the next six years.
If elevated CO2 causes the water use of individual leaves to drop, plants in arid environments will respond by increasing their total numbers of leaves. These changes in leaf cover can be detected by satellite, particularly in deserts and savannas where the cover is less complete than in wet locations, according to Dr Donohue.
At the end of last year, Kevin Sivula, one of the collaborators at the LPI laboratory, presented a prototype electrode based on the same principle. Its efficiency was such that gas bubbles emerged as soon as it was under a light stimulus. Without a doubt, the potential of such cheap electrodes was demonstrated, even if there was still room for improvement.
Rooftop Solar Array on University Park Elementary School Will Generate Clean Energy and Revenue for Town and County Public Schools
This story about an elementary school solar array in University Park, MD provides a good example of how shared clean energy can benefit more than one user, environmentally and financially.
