Track 13, Reading 7a Powering the Planet Despite modern society's heavy dependence on fossil fuels for energy,
2
most people are aware that the supply of these fuels is finite.
3
As oil and other fossil fuels become more costly and difficult to find, researchers are looking at alternative energy sources,
4
including solar, wind, and even nuclear power.
5
But which substitute, if any, is the right one?
6
Solar.
7
Solar panels catch energy directly from the sun and convert it into electricity.
8
One of the world's largest solar power stations is in the Indian state of Tamil Nadu,
9
where more than 2 .5 million solar panels have the capacity to generate enough power for 750 ,000 people.
10
But unlike the burning of fossil fuels, the process used to create all that solar energy produces no emissions.
11
Today, however, solar power provides less than 2 % of the world's energy,
12
primarily because the cost of the panels is still very high.
13
But price is only one issue.
14
Clouds and darkness also cause solar panels to produce less energy.
15
This requires that additional power sources, such as batteries, be available.
16
Some scientists think the solution to this problem can be found in space, which is the ideal place to gather energy from the sun.
17
With no clouds and no night time, a space -based solar power station could operate constantly.
18
These stations would send the power back to Earth, which could then be turned into electricity for consumption.
19
Advocates of solar space stations say this technology would initially require a lot of money, but eventually, it could provide continuous,
20
clean energy that would be cheaper than other fuels.
21
Also, unlike other energy sources, solar power from space would last as long as the sun shines,
22
and would guarantee everyone on Earth all the energy they need.
23
Wind Wind, the fastest -growing alternative energy source, is another way of collecting energy from the sun.
24
Wind is caused by the sun's heat rather than its light.
25
Therefore, unlike solar power, wind power works well even on cloudy days.
26
All over the world, incentives designed to decrease the dependence on oil and coal have led to a steep increase in wind -powered energy.
27
Today, Asia leads the world in wind power, producing around 230 ,000 megawatts,
28
the equivalent of 230 large coal -powered plants.
29
Europe produces nearly 180 ,000 megawatts.
30
North America remains a distant third at 105 ,000.
31
Despite its successes, some people are protesting wind power development, saying the turbines are both noisy and ugly.
32
Just outside England's Lake District, a protected national park, a dozen existing wind towers are due to be removed.
33
This is a high -quality landscape, says one local homeowner.
34
They shouldn't be putting those things in here.
35
There are other challenges, too.
36
If the wind doesn't blow, the turbines are not able to produce adequate energy.
37
As a result, other power sources are needed.
38
In contrast, a strong wind can create too much power.
39
In cases like this, the energy company must sell the extra power at a much reduced rate, which is not good for business.
40
What's needed for both wind and solar is a way to store a large energy surplus.
41
However, most systems are still decades away from making this a reality.
42
On the plus side, both wind and solar power enable people to generate their own energy where they live.
43
People can have their own windmills or solar panels with batteries for calm days.
44
Nuclear In the 1970s, nuclear power was seen as the main energy alternative.
45
Nuclear power produces vast amounts of electricity more cheaply than gas or coal with no carbon emissions.
46
For a number of years in the 1980s and 90s, however, use of nuclear power declined due to accidents,
47
concerns about nuclear waste storage and disposal, and high construction costs.
48
Today, times are changing.
49
Worldwide, about 450 plants generate 11 % of the planet's electric power,
50
and some countries have invested heavily in nuclear energy.
51
France, for instance, gets three -quarters of its electricity from nuclear power, the highest percentage of any country.
52
China has started to build one or two new plants a year, and India has also begun to utilize nuclear energy on a
53
large scale however there are still concerns about the safety of
54
nuclear power as seen for example at the fukushima nuclear power
55
plant in japan the country had to close the nuclear reactors at fukushima
56
when the plant was hit by a tsunami
57
and as a consequence began releasing substantial amounts of radioactive materials many still believe however
58
that nuclear power is one of the future's greenest energy alternatives.
59
In the end, are any of these sources alone the answer to our current energy problems?
60
The short answer is no, but used in some combination, along with other power sources,
61
we may find ways to reduce and eventually eliminate our dependence on fossil fuels.

वर्तमान स्थिति
आज की दुनिया में, ऊर्जा के लिए हमारी निर्भरता मुख्यतः जीवाश्म ईंधनों पर है, लेकिन हम सभी जानते हैं कि ये संसाधन सीमित हैं। ऐसे में वैकल्पिक ऊर्जा स्रोतों की खोज एक महत्वपूर्ण विषय बन गया है। वीडियो में चर्चा की गई है कि कैसे सौर ऊर्जा, पवन ऊर्जा, और परमाणु ऊर्जा हमारे भविष्य के लिए संभावित विकल्प हो सकते हैं। इसमें भारत के तमिलनाडु में सौर ऊर्जा के बड़े संयंत्र का उदाहरण दिया गया है, जो 750,000 लोगों के लिए ऊर्जा उत्पन्न करता है।
उपयोगी शब्द समूह और संयोजन
- सौर ऊर्जा की क्षमता - Solar energy capacity
- पवन ऊर्जा का विकास - Development of wind energy
- परमाणु ऊर्जा संयंत्र - Nuclear power plant
- जीवाश्म ईंधनों पर निर्भरता - Dependence on fossil fuels
- ऊर्जा के वैकल्पिक स्रोत - Alternative sources of energy
आपकी शैडोइंग चुनौती
अब, आइए एक छोटी सी चुनौती लें। वीडियो में 'सौर ऊर्जा' और 'पवन ऊर्जा' के बारे में कुछ वाक्य सुनें और उन्हें दोहराएं। ध्यान दें कि आप कैसे अंग्रेजी उच्चारण में सुधार कर सकते हैं। आप इस शैडोइंग तकनीक का उपयोग करके अपने बोलने के कौशल को बढ़ा सकते हैं। इसे करने के लिए, वीडियो के एक हिस्से को सुनें और उसके बाद खुद को रिकॉर्ड करें। फिर, अपने उच्चारण की तुलना वीडियो में प्रस्तुत उच्चारण से करें। इस प्रक्रिया को नियमित रूप से करने से आपको अंग्रेजी शैडोइंग में महारत हासिल करने में मदद मिलेगी।
याद रखें, वीडियो से अंग्रेजी सीखें और shadow speak तकनीक का उपयोग करें। यह न केवल आपकी सुनने की क्षमता को बढ़ावा देगा, बल्कि आपको आत्मविश्वास के साथ बोलने में भी मदद करेगा।
इस वीडियो का व्याकरण
वक्ता जिन संरचनाओं का सबसे अधिक प्रयोग करता है, वीडियो के असली शब्दों के साथ:
| संरचना | वीडियो में |
|---|---|
| Passive voice be + past participle — ज़ोर इस पर कि क्या होता है, न कि कौन करता है | can be found · be turned · is caused |
| Present perfect have/has + past participle — बीता हुआ काम जिसका असर अभी भी है | have led · have invested · has started |
| Relative clauses who / which + उपवाक्य — व्यक्ति या वस्तु के बारे में अतिरिक्त जानकारी | space, which is · rate, which is |
शैडोइंग तकनीक क्या है?
शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
