Cars and trucks are surely convenient, and most of US couldn't live without them, but
they have become very expensive to run and harmful to the environment. Gas prices have
been increasing, and carbon-dioxide emissions from cars pollute the environment and
contribute to global warming. As a result, hybrid cars and electric cars have been
economical and environmentally friendly alternatives to traditional vehicles. They would
be a good choice for the near future.
Hybrid cars combine two sources of energy such as a battery-powered electric motor
and an internal combustion engine. The driver decides which source of power is
appropriate for a given journey. Short rides to the grocery store or the post office could
use the electric motor, while weekends in the country may require the internal combustion
engine.
Electric cars run on rechargeable batteries rather than fuel. They are rather quiet on
the road. The best thing about them is they cause about 97% less pollution than regular
cars. But there are some disadvantages, too. The battery runs out of energy after driving a
short distance, and it takes much time to recharge the battery. Electric cars also are
expensive. Their batteries are still expensive and wear out in just a few years.
- internal combustion engine: động cơ đốt trong
- emission (n): sự thải ra
- wear out (v): hao mòn
