"It's not just about increasing service; it's also about becoming much more efficient and reducing greenhouse gases, and it's about economic development in the Bay Area".
If the power grid in America alone were just 5% more efficient, it would save greenhouse emissions equivalent to 53m cars, calculates IBM.
But as the latest generations of engines become more efficient, any reductions in greenhouse gases are outweighed by the global growth in air traffic, especially in Asia.
These developments should also help make crop production in terrestrial controlled environments (plant growth chambers and greenhouses) more efficient and, therefore, make these alternative agricultural systems more economically feasible food production systems.
Although they are more efficient and generally produce fewer greenhouse gases than gas stoves, most buyers apparently aren't ready to go quite that green, Mr. Namer said, and about two-thirds have chosen the more traditional gas stoves.
The chapel-shaped glass greenhouse is relatively more efficient, but its evolution remains slow because of its investment cost and amortization.
Methane is a dangerous greenhouse gas, 20 times more efficient at trapping warming solar radiation than carbon dioxide.
Over time, officials contend, new technologies, like hybrid-electric cars and more efficient power plants, will lower energy costs and greenhouse gas emissions at the same time.
The present investigation showed that the productivity of asymmetric greenhouse type still (ASGHT) having mirrors on its inside walls was higher than that of the symmetric greenhouse type still (SGHT) and more efficient.
They found that the productivity of asymmetric greenhouse-type solar still is more efficient.
