[单项选择]Discussions about reducing greenhouse gas emissions usually concentrate on cleaner ways of generating energy: that’s because they promise that we can lower emissions without having to change our energy-hungry ways. But whereas new generation techniques take years to come on stream, efficiency can be improved today, with existing technologies and know-how.
To calculate how much energy could be saved through such improvements, Julian Allwood and colleagues at the University of Cambridge analysed the buildings, vehicles and industry around us and applied "best practice" efficiency changes to them. They found that 73 percent of global energy use could be saved by introducing such changes.
Many people are unaware of the scale of opportunities for reducing energy demand, says Allwood. By showing how global energy demand can fall to a quarter of its current level without any decline in services, the team hope to redress the balance. "We think it’s pretty unlikely that we’ll find a g
A. Changing the situation of global warming.
B. Generating energy in a much cleaner way.
C. Improving efficiency with new technologies.
D. Lowering emissions with existing techniques.

Bush Concerned about Rising Gas Prices

President Bush says a variety of global forces are to blame for crude oil prices topping ＄70 a barrel.
"There is a tight supply worldwide, and we have got an increasing demand from countries like India and China, which means that, any disruption in supply, or perceived disruption of supply, is going to cause the price of crude to go up, and that affects the price of gasoline," he said.
The president says prices are also up due to increasing domestic demand, as Americans are driving more, now that the cold winter weather is ending, and because states are switching their fuel-mix to a warmer-weather blend.
"The combination of these changes creates higher gasoline prices, and I am concerned about higher gasoline prices. I am concerned about what it means for working families and small businesses, and I am also mindful that the government has the responsibility to make sure that we
