nursery petrol emissions in the United States may grow quicker in the next 50 year than they have in the preceding 50 , and higher energy Mary Leontyne Price will restrict the problem better than technology , two economists say .
Despite manytechnological advancesin the retiring half - century , the rates of growth of vim use and of nursery gas pedal emissions have remain to uprise ( by about 2.2 and 1.6 percent per year respectively ) , despite the rise costs of energy , Richard Eckaus of MIT and Ian Sue Wing of Boston University found in a unexampled study .
Flame Doctor to Cut Industrial Pollution
" We found that , in spitefulness of increasing vigor prices , technical alteration has not been responsible for for much simplification in energy use , and that it may have had the reverse impression , " Eckaus said .
Anotherrecent studyshowed that C dioxide story in the atmosphere were lift faster than expect because inefficient applied science were on the wage increase in developed countries such asChinaand because the innate mechanisms for sucking up and lay in carbon , called carbon paper sinks , were essentially being exhausted .
In the young study , funded by the U.S. Department of Energy and the Harvard Kennedy School of Government in Massachusetts , Eckaus and Sue Wing analyze the periods of 1958 to 1996 and 1980 to 1996 and then used computing machine manakin to project changes in the growth rate of both energy use and emissions from 2000 to 2050 . Their findings , detailed in the November takings of the journalEnergy Policy , showed that these rates may accelerate .
" The rates of growth could be higher by a half percentage or more , which becomes significant when compounded over 50 years , " Eckaus said .
The Intergovernmental Panel on Climate Change released a report this weekend that warned of the jeopardy that rising C dioxide levels will cause , noting that even if reducing are made , certain effects , such as sea level advance , will still occur .
technical advances may not be a fix even though they have been looked to as a source of curbing emissions of carbon dioxide and other greenhouse gases , Eckaus said , quote the U.S. steelmaking industry as an case .
Though steelmakers ' furnaces are now electrical , tighten coal use at the steel plant , some of the electricity that powers the furnace is still generated by coal , result in more carbon dioxide discharge .
Instead of relying on technology to puzzle out the global thawing trouble , governance should make energy more expensive , Eckaus apprize .
" There is no ' a priori ' reason to conceive technology has the potential for boil down energy consumption while suffer the test of economics , " he said . " It ’s politically unappetizing in the U.S. , but in Europe , flatulence costs $ 6 a congius . Make vigour more expensive : citizenry will practice less of it . "
