As a senior high school student, I am very busy with my studies. Although I am very fond of watching television, I can only spend an hour after dinner on my hobby. Of all the TV programs, I like the news and documentaries best.
The news programs shown on all TV channels at 7:00 p.m. help me to know almost everything about different places in our country and important events happening all over the world. Through these programs, I can also know about the main national and international sporting events.
The documentary programs at weekends are my favorites. By watching them, I can learn a great deal about human civilizations, the wonders of nature and the amazing inventions and discoveries of great people in the world.
Watching television is my hobby. I cannot imagine a day in my life without watching it.
Electric Cars
Hybrids vehicles, with their combination of both gas and battery power, represent 3% of the cars on the road today, up from zero just ten years ago. Fully electric cars like the Nissan Leaf and Tesla are mere curiosities, representing only 0.1% of all cars purchased in the U.S.
It might seem like a slow start, but electric cars will soon form the majority of all vehicles. Here’s why:
Except for early adopters of technology and diehard environmental customers, most people aren’t buying a fuel type, they’re buying transportation. They may want speed or economical transportation or family-friendly minivans, but how the vehicle is powered isn’t their main concern.
Examples like the Tesla have shown that electric vehicles perform on par with gas-powered cars. What limits their adoption then? Two factors: cost and range (and charging infrastructure, to a lesser extent, but that will be remedied when there is more demand).
The Nissan Leaf battery pack alone costs about $18,000 (though government incentives bring down the overall vehicle cost to the customer). When comparable gas-powered cars are about $20,000, the high cost of the battery pack alone is a huge barrier to widespread adoption, whether the cost passed on to the customer or the government, or hidden by the manufacturer.
Ramez Naam, author of The Infinite Resource: The Power of Ideas on a Finite Planet, recently explained that lithium-ion batteries have a fifteen year history of exponential price reduction. Between 1991 and 2005, the capacity that could be bought with $100 went up by a factor of 11. The trend continues through to the present day.
This exponential reduction in battery cost and improvement in battery technology, more than anything else, will affect both the cost and range of electric cars. By 2025, that Nissan Leaf battery pack will cost less than $1,800, making the cost of the electric motor plus battery pack less than the price of a comparable gasoline motor. Assuming even modest increases in storage capacity, the electric vehicle will rank better on initial cost, range, performance, and ongoing maintenance and fuel costs.
With both lower cost and better performance, electric vehicles will likely overtake gasoline-powered ones by about 2025.

Nowadays, energy is being run out more and more. We need to save energy because nobody of us can lives without energy. So why don't we start to do it right in our home ?
We have many ways to save energy in our home. One of those ways is using electricity, water and gas economically. Such as we should turn off the light in room when we go out or in unnecessary situations, avoid wasting water, shut the kitchen stove when stop cooking.
Besides, we should use electrical equipments which are energy - saving. Such as using lights and fans that have low capacity, or using equipments which reserve electricty. Not only do these help us to save money but also they work effectively
In addition, we should frequently check electrical equipments in our home in order to fix opportunely .
In summary , we need to save energy so that energy isn't run out and continues to serve human's life.
In our daily life, we rely on many materials. Wood, metal, glass and plastics all have environmental consequences. Think about the impact of every product you use. For example, the lighter an object, the less fuel is required to transport it. A heavy suitcase in the boot of a car will require the car to consume more fuel during its journey. The same goes for all product packaging. Therefore, buying food wrapped in lightweight materials thus helps the environment.
The energy is precious, including renewable and non-renewable energy. Therefore, we need save energy. As a student, we should turn off the lights when leaving or going out to save electricity. Moreover, we should use low energy light bulbs. Finally, we should avoid using cars or motorbikes for short trips. In sum, I hold the view that we should "turn off when not using".

Nowadays, energy is being run out more and more so it is one of the most important things of our life. We need to save energy because nobody of us can lives without energy. So why don't we start to do it right in our home? We have many ways to save energy in our home. One of those ways is using electricity, water and gas economically. Such as we should turn off the light in room when we go out or in unnecessary situations, avoid wasting water, shut the kitchen stove when stop cooking. Use a microwave instead of a stove to reheat food. Use rechargeable batteries instead of disposable batteries... Besides, we should use electrical equipment which are energy - saving. Such as using lights and fans that have low capacity, or using equipment which reserve electricity. Not only do these help us to save money but also they work effectively.
