由“Change Bulbs”部分第一段第二句“Forty percent of that powers old-fashioned incandescent light bulbs--a 19th-century technology that wastes most of the power it consumes on unwanted heat.”可知照明消耗了全世界电能总量的20%,而这些电能的40%又用在了老式的白炽灯照明上。这项19世纪的技术把其消...
Too much money is spent maintaining and repairing old buildings. Some people think that they should be knocked down and give way to modern buildings. To what extent do you agree or disagree? Give reasons for your answer and include any relevant examples from your own knowledge or experience. ...
Projectors are known to vary wildly when it comes to their power consumption, they tend to range from 50W for the smallest projectors, up to 150-800 watts for the much larger ones. Brightness is one of the settings that heavily dictates how much a projector will consume, as it’s a very...
However, much of the current emphasis in scientific research and modeling focuses on supply-side solutions and removing carbon dioxide from the atmosphere. This includes bioenergy production with carbon capture and storage (CCS), which involves serious tradeoffs and risks due to intensive land-use req...
