Energy efficiency: Some states perform better than others

The top states for encouraging energy efficiency are Massachusetts at No. 1 and California at No. 2, according to a clean energy research organization.

Both have strategies and programs in place to enhance the clean energy mix of their energy production and encourage a shift to cost-saving measures and clean energy. Their efforts have been followed, mimicked and analyzed many times.

But the bottom performers? Not so much.

"There is plenty of room for improvement," say Michael Sciortino, Rachel Young and Steven Nadel in "Opportunity Knocks: Examining Low-Ranking States in the State Energy Efficiency Scorecard." They work for the American Council for an Energy Efficient Economy, a nonprofit research and policy analyst.

The worst 10 states in promoting energy efficiency in descending order, with the last being the worst, are: South Dakota, Alabama, Missouri, West Virginia, South Carolina, Oklahoma, Kansas, Mississippi, Wyoming and North Dakota. ACEEE ranks the states according to policies and programs that advance efficiencies in buildings, transportation and industry.

EPA honors highly efficient building designs

Efforts to save energy by designing more efficient buildings continue to gain steam.

The U.S. Environmental Protection Agency recently recognized about 100 commercial building design projects estimated to be nearly 40 percent more energy efficient than typical buildings. The agency made the announcement at the American Institute of Architects National Convention in Washington, D.C. The projects were submitted by 43 architecture firms and achieved Designed to Earn the Energy Star certification.

Projects that receive Designed to Earn the Energy Star certification are In total, the projects recognized at the convention are estimated to prevent nearly 175,000 metric tons of greenhouse gas emissions annually and save more than $23 million in annual energy costs across 10 million square feet of commercial space.

"These new building design projects are helping to save energy and money from the ground up for American families and businesses," says Gina McCarthy, assistant administrator for EPA’s Office of Air and Radiation, in a statement. She says they range from skyscrapers to rural elementary schools.

Net-zero construction gains ground in U.S.

Apollo 11 touched down on the Sea of Tranquility with the world watching.

The date was July 20, 1969.

"Houston, Tranquility Base here. The Eagle has landed," the spacecraft announced. Some hours later Apollo 11 astronaut Neil Armstrong took man's first steps on the Moon followed closely by fellow spaceman Buzz Aldrin.

Their footprints at Tranquility Base likely remain, a small sign of a massive accomplishment.

NASA's back in the historic footprint game again but in an entirely different way. The space agency, now somewhat redirected and fiscally leaner with the closure of the Space Shuttle program, has been constructing a facility that takes inspiration for its name from Tranquility Base and seeks to be a landmark in another sense, leaving as little footprint as possible.

Here on Earth

Sustainability Base, at Ames Research Center in Moffett Field, Calif., has been dubbed NASA's latest mission on Earth. The facility has received LEED platinum certification, the highest level of Leadership in Energy and Environmental Design rating by the U.S. Green Building Council. Its design incorporates natural lighting, shading and fresh air. The interior boasts non-toxic materials and is, according to NASA, "a living prototype for buildings of the future."

UC Merced sets sustainable bar way, way up

The newest campus in the University of California system is quietly becoming a sustainable model and developing a reputation as a center for world-class research.

The University of California, Merced just had its seventh building certified gold by the U.S. Green Building Council’s Leadership in Energy and Environmental Design, or LEED, program.

Its long-range plan, which embraces economic, social and environmental sustainability in campus facilities, was named to the American Institute of Architects' Committee on the Environment Top 10 Green Projects program.

And physics professor Sayantani Ghosh, along with Richard Inman, Georgiy Shcherbatyuk, Dmitri Medvedko and Ajay Gopinathan recently won recogntion of their research in renewable energy in the clean energy press.

Renewable research leader

Zachary Shahan of cleantechnica.com explains the research breakthrough as an effort "to redesign luminescent solar concentrators in order to make them more efficient at sending sunlight to solar cells."

Trend to slash high-rise electric bills sweeps industry

King Kong immortalized the Empire State Building -- more than once.

And while its status as the biggest and tallest has been eclipsed a number of times since Pres. Herbert Hoover turned on the lights May 1, 1931, the iconic skyscraper continues to lead the nation. However, now it's gaining fame as perhaps the best known energy efficient high-rise.

Others have followed, drawn by the prospect of saving money in a turbulent economy through relatively simple and cost-effective upgrades that can pay off in a matter of years. The U.S. Green Building Council says green commercial building retrofits actually exceeded new construction some months in 2011.

"Deep energy savings (30 percent to 40 percent) can be mined from existing buildings," says a July 2011 study by Vancouver, Wash.-based New Buildings Institute.

Energy Star fast tracks

A barometer of the trend has been the U.S. Environmental Protection Agency's list of cities with the most buildings qualifying for Energy Star status. Energy Star certified buildings use an average of 35 percent less energy and are responsible for 35 percent less carbon dioxide emissions than typical buildings. Buildings are responsible for about 40 percent of carbon dioxide emissions, while commercial buildings make up half that.
