od. From 20q and 15q respectively in 1980, gas showed an initial fall and coal a gradual increase, with the two fuels equal between 1985 and 1990. Consumption has fluctuated since 1990 but both now provide 24q. Coal is predicted to increase steadily to 31q in 2030, whereas after 2014, gas will remain stable at 25q. In 1980, energy from nuclear, hydro and solar/wind power was equal at only 4q. Nuclear has risen by 3q, and solar/wind by 2. After slight increases, hydropower has fallen back to the 1980 figure. It is expected to maintain this level until 2030, while the others should rise slightly after 2025. Overall, the US will continue to rely on fossil fuels, with sustainable and nuclear energy sources remaining relatively ,也不能閑死在家里!寧可去碰壁,也不能面壁。是狼就要練好牙,是羊就要練好腿。什么是奮斗?奮斗就是每天很難,可一年一年卻越來越容易。不奮斗就是每天都很容易,可一年一年越來越難。能干的人,不在情緒上計較,只在做事上認(rèn)真;無能的人!不在做事上認(rèn)真,只在情緒上計較。拼一個春夏秋冬!贏一個無悔人生!早安!—————獻(xiàn)給所有努力的人.學(xué)習(xí)參
