1. Read the passage given below and answer the questions that follow:
Sometimes solutions to large problems can be fairly simple. Take the
energy problem. Solutions focus on redesigning the automobile, boosting
the use of nuclear and other clean energy and so on. But we could
make a simpler start, says Matt Precott, a British environmental scientist.
He wants a complete ban on the traditional light bulb. The cheapest
way for developing countries to make optimum use of limited energy
supplies, and for developed countries to achieve cuts in their carbon
dioxide emission, says Prescott, is to augment energy efficiency.
As a first step, he suggests making light bulbs – a major source
of waste in energy consumption – museum pieces. This could even
encourage people to ‘aim higher’ in increasing efficiency
in everything from hot water systems to home insulation, thereby cutting
Green House Gas (GHG) emissions.
After all, it is domestic energy consumption that causes more than
25 percent of the global GHG emission of carbon, sulphur and nitrogen
dioxide. Recent research indicates that the wider use of ‘green
lighting’ can cut this dramatically. Compact fluorescent light
bulbs, for instance, use only about a quarter of the energy of incandescent
bulbs to produce the same number or more lumens. That they also last
about ten times longer than regular bulbsis a bonus. Compact fluorescents
may be more expensive initially, but the long-term savings would surely
offset this. Light emitting diodes (LEDs) also offer an excellent
alternative to the light bulb.
It makes sense in energy-starved countries like India to have regulated
energy-efficiency campaigns that could reduce waste and pollution,
and stimulate innovation. Let’s start with light. The public
should be made aware of concepts like ‘task lighting’:
concentrating light only where it’s needed. This avoids waste
of energy and since task lighting uses lower watt bulbs, you don’t
annoy others in the area either with an intrusively bright light.
The government could kick off the process by providing tax incentives
to manufacturers to market more efficient fluorescent bulbs.
(i) What does the writer mean when he says that traditional light
should be made ‘museum pieces’?
