Read the passage and answer the questions that follow. (1). „Why do batteries matter? Look at all your electronic devices: from laptops to smartphones to Kindles or iPads, even your watch. Those electronics are getting more energy-efficient and require less energy than they used to. But as they do, people get greedy and want their capabilities to increase. The battery, or how much energy you can 05 store in a given volume and weight, is the defining factor in this whole field. Then there are electric cars. If we can make batteries with double the "energy TR2Z density of today's and drive the price below $200 per "kilowatt-hour (versus $300 to $800 today, depending on type and weight), we could have a car with a 300-mile range, even with the air conditioner or heater turned up, that would sell for $25,000 to $30,000. The 10 Department of Energy's goal is to get batteries to $150 per kilowatt-hour by the year 2020. 01 Finally, there are the "utility-scale batteries, which are very important for renewable TR28 energy. Wind and solar power are going to become more common. Wind is already the second-cheapest form of new energy, after shale gas, and it will become the cheapest 15 15 within a decade. Right now "utility companies get about 4 percent of their power from renewable sources other than "hydro- and that 4 percent is roughly all from wind. We may see a day when renewables make up 50, 60, 70 percent of the total supply of energy. Utility companies will need batteries to stabilize the flow of renewable energy into the *grid, and also require a better electrical control system to (3)do the switching. People 20 may have these batteries at their homes instead of generators. All of this would create a huge market. But the effects would be more profound. T There are mountainous places even in the U.S., like western Alaska, that will never be connected to the electric grid. There aren't enough people, and the distances are too great. There are many parts of South Asia like this, too. But they will have solar and 25 wind power - which, in 10 or 15 years, are going to be as cheap as any other form of energy, or cheaper. Once you have "storage systems, you can put a little "solar installation on your roof or "a plot of land, and then you will have your electric supply! It will be like cellphones' "leapfrogging the "land-line era. It will transform the prosperity of the world. 【Notes】 energy density エネルギー密度 (ここでは電池の容量を意味する) kilowatt-hour キロワット時 (1キロワットの機器を1時間使ったときの消費電力量) utility-scale 電力供給に使う規模の hydro utility company t storage 貯蔵 (ここでは電気を蓄えておくことを意味する) grid solar installation a plot of land 一画の土地 land-line 地上 (の電話) 線 by a factor of two (増減の幅が)2倍で (50pts.) leapfrog 〜を一足跳びにする

「,well behind 」の部分の構造、意味を教えてください。

[Review] Back in the late sixties, thinkers on both sides of the Atlantic were troubled by problems which may seem strange to us today: they were worried that the leisure age which they believed was fast approaching would leave people with too much time on their hands. They were worried that the work ethic was losing its grip on a new rebellious generation and they pondered how they would motivate people to work. They needn't have worried. The much-predicted "leisure age" promised by technology has not materialized. In fact, quite the reverse: people are working harder than ever. There is less leisure time and, most surprising of all, the very workers with the greatest bargaining power are choosing to work the hardest. The problem is the burnout of white- collar Britain. For over a century, the average number of hours spent working over a lifetime slowly declined in Britain. The historian James Arrowsmith has calculated that in 1856 our ancestors put in 124,000 hours over a 40-year working life and, by 1981, it was 69,000. There it remained for a decade, but in the early nineties it began to increase again. On average full-time British workers now put in 80,224 hours over their working life, and that figure rises to 92,000 for those on a 50-hour week, which is common among the self- employed, the skilled, and professional and managerial workers. Many are working the kind of hours that would have been familiar to factory workers in the middle of the 19th century. The only difference is that now it's the bosses who are more likely to be putting in the hours than those on the shop floor. Britain has followed a US model of all work, no play, in contrast to continental Europe. Full-time workers in Britain now work the longest hours in Europe an average of 43.6 hours per week compared with an EU average of 40.3. Even more marked is the difference in holidays between Britain and continental Europe; the UK has, on average, 28 days a year, well behind France with 47, Italy with 44 and Germany with 41. Add the difference in weekly hours and holidays and it amounts to the British working almost eight weeks a year more than their European counterparts. -
