It is becoming more and more common to install solar panels on roofs in order to obtain green electricity, but not all roofs are equally suitable.
While the United States has not yet seen national legislation aimed at reducing corporate carbon footprints and promoting sustainability, state and local governments across the country have begun to take bold steps in their effort to protect the environment.

Sanborn Regional School District in Kingston, N.H., has signed the world's first power purchase agreement for ultra-efficient solar hot air, which will reduce heating bills.
Siluria is the first and only company to develop an economically advantageous, methane-based alternative for producing fuels and chemicals normally derived from oil.
NASA has awarded the largest prize in aviation history, created to inspire the development of more fuel-efficient aircraft and spark the start of a new electric airplane industry.
The school from College Park, Maryland competed against 18 other collegiate teams to build an aesthetically pleasing, architecturally innovative and well-engineered energy efficient living space that generates its energy from solar power
Electrical energy storage and its management is becoming an urgent issue due to climate change and energy shortage.
The U.S. Environmental Protection Agency (EPA) recently announced plans to help an estimated 125 local, state, and tribal governments create more housing choices, make transportation more efficient and reliable and support vibrant and healthy neighborhoods that attract businesses.
A team of Purdue University researchers has invented a prototype water-disinfection system that could help the world's 800 million people who lack safe drinking water.
In a broad green stroke across campus, the University of Michigan will invest $14 million in new commitments to achieve ambitious environmental goals.
A University of Arkansas study suggests that “lifetime” savings claims on product labels are not the most effective method to reach consumers regarding the benefits and potential savings from using energy-efficient products.
The way in which global warming causes many of the world’s organisms to shrink has been revealed by new research from Queen Mary, University of London.
At the 2008 Winter Olympics, Chinese officials didn't want the gold medal for "most polluted air." Reducing air pollution in an urban area like Beijing will require large, regional strategies according to scientists from Pacific Northwest National Laboratory, Georgia Institute of Technology, and Peking University. They studied the effects of emission reduction efforts at the Beijing Olympics.
Predictions of the ground-level pollutant ozone will be more accurate in future according to research published by environment scientists at research centers including the University of Birmingham in the journal Nature Geoscience.
While water-related conflicts and shortages abound throughout the rapidly changing societies of Africa, Asia and Latin America, there is clearly sufficient water to sustain food, energy, industrial and environmental needs during the 21st century, argues the Challenge Program on Water and Food (CPWF) of the CGIAR in two special issues of the peer-reviewed journal, Water International (Volume 35, Issue 5 and Volume 36, Issue 1), released at the XIV World Water Congress.
Scientists at Cambridge University are exhibiting a prototype table that demonstrates how biological fuel cells can harness energy from plants.
Because costs of trash collection have increased significantly while landfill space diminishes, radio frequency identification (RFID) holds the potential to dramatically reduce the volume of trash and increase the amount of materials being recycled.
Global emissions of carbon dioxide (CO2) increased by 45 percent between 1990 and 2010, and reached an all-time high of 33 billion tons in 2010. Increased energy-efficiency, nuclear energy and the growing contributions of renewable energy are not compensating for the globally increasing demand for power and transport, which is strongest in developing countries.
Even though many view environmental protection as coming with an extra cost, a California caterer has managed to cut costs tremendously by going green.
