Air and Water essays A major transition in the modern energy age began in the 1970s, when the big nations industry started to grow up rapidly. The use of oil was very important and overnight, oil prices shot through the roof, and the trend of ever-cheaper, ever-more-plentiful energy sources were in need. Another player on the modern energy stage is nuclear power. An industry that didn't exist 40 years ago is now at a huge amount of production, producing 20 percent of the nation's electricity. Ironically, the industry is fading out. New orders ceased 20 years ago, and as aging plants reach the end of their lives, they are closing, one by one. All the non-renewable energy resources have positive and negative affects to the nature. However Nuclear Energy is the most dangerous one, as we can see what happened in Chernobyl in 1986, and it is dangerous if the nations use Nuclear Energy to kill people like at the end of the world war. It is not a dream to think of solar power that is cheap enough for universal use a world full of zero-polluting electric cars. Wide-scale use of fuel cells for powering buses and other forms of public transport. Chicago and Vancouver are two cities which have pilot programs using fuel cells to power some of their public transport buses. Use of fossil fuels confined to petro-chemical products and fuel cell feedstock. Nuclear fusion or some other advanced nuclear process, supplying all base load power. (Solar) Also, there is continued interest and research into fusion power. Since fusion generates temperatures of millions of degrees, the main difficulty in developing fusion power has been in containing the heat of the reaction. Fusion is an expensive source of energy right now, but it might cost much cheaper in the near future. It is not very hard to guess that in the near future, all the energy sources will be much cheaper. The technology is changing almost everyday, it was not possible to dre ...

Should I choose online or classroom SAT prep

Should I choose online or classroom SAT prep SAT / ACT Prep Online Guides and Tips Like most things in life, the answer to this question is: it depends. In this case, it depends on what kind of learner you are, what your schedule looks like, how quickly you need to beef up your skills, and how much you (or your parents) want to pay. Online education is still young, trying to find its footing as technologies become more sophisticated and people become more connected to the internet 24/7. And SAT prep is also entering a phase of speedy evolution, as theCollege Boardannounced recently that willprovide free preparation for theredesigned testthat begins in the Spring of 2016. But if the College Board’s record for (lack of) transparency is any indication, the prep they provide will be incomplete at best. They've been providing "College Board Official Prep" for decades and certain students benefit from more than that. After all, their job is to present questions that can’t be â€Å"tricked†! So it’s important to keep on top of all your options, as you only have to take the test once if you prepare well. Like it or not, the SAT is probably an important factor in the direction of your post-high school life. A quick comparison of online and classroom SAT prep: Online Classroom where wherever you want major cities when whenever you want late (average weekday start time 7pm) or early (average weekend start time 8am) setting home, library, your choice high school and college classrooms customization fully customized algorithmic program* none timed practice 10 full practice tests* none (no time!) program design self-paced pre-planned (if you get sick, too bad!) upgrades every 2 weeks when the test changes (approx. every 10 years) progress tracking constant and precise none instructor availability 24/7 during class time (about 3-6 hours per week) feedback constant and updated very little *with PrepScholar When Classroom is Better: Of course, there are advantages to traditional classroom instruction that are difficult to quantify. There are some types of students who will do well in a classroom setting: students who require the presence of an authority figure to get anything done students who enjoy the high school experience students who aren’t much higher or lower than the average ability of the class students who are willing to ask every single question they have students who prefer pen-and-paper work to online work If you or your student(s) fall into a few of these categories, you may want to consider classroom preparation. But most students don’t. Obviously, online SAT prep has a ton of advantagesand its abilities are expanding every day. The bottom line is that most proponents of classroom teaching don’t know what technology is capable of. Most educators, in high schools and big prep companies, are middle-aged or older. Their experience with technology is limited at best. PrepScholar (time to toot our own horn!) is founded and staffed entirely by people who have been using computers our whole lives. The company was founded on the principle that technology can provide enriching, compelling educational experiences and we are constantly working to push the boundaries of what we can deliver. We aren’t the least biased authority on the advantages of online test prep, but we may be the best informed. Next Up: Should you take the New SAT or Old SAT?
