Read the passage below carefully and choose the correct answer A, B, C, or D:

In the future, maybe all cars that run on petrol will be replaced by solar cars, which have

been around for a while, but with recent developments in solar car design and the

measurement of photovoltaic cells becoming smaller, the dream of a truly efficient solar car

is more reality than fantasy. A solar car is a vehicle powered by photovoltaic cells, also

called solar cells, which convert sunlight (light energy) into electrical energy. As a source of

energy on earth, there is nothing like the sun: in a mere one thousandth of one second

(.001), the sun emits enough energy to fulfill our planet's energy needs for the next 5,000

years. It is a staggering fact, and an exciting one. Since the energy from the sun is

responsible for renewable resources such as wind, tides, and heat, solar energy seems to

offer the brightest future for not only cars, but for the entire energy crisis. Despite the

appearance that solar energy may be the least feasible among the current crop of

alternative fuel propositions, new solar powered devices and more specifically solar

powered cars are beginning to be developed. How do Solar. Cars work?

The photo-voltaic cells absorb photons from sunlight. This action generates heat, which the

cells then convert into electrical energy and stores in an on-board battery. This process of

conversion is called the photovoltaic effect. Not surprisingly, such a vehicle has zero

emissions, and is very environmentally friendly. Unfortunately, at the moment photovoltaic

cells are extremely inefficient, yet as time progresses the efficiency of these cells will grow.

This will make solar energy and solar cars the fuel and car of the future-a closer reality.
