Question

What measures would you take to conserve electricity in your house?
A. Use of fluorescent tubes or CFL
B. Put off the fans and lights when they are not required.
C. Maximum use of solar radiation and the use of solar water heating systems during winters.
D. All of the above.

Answer 1

Hint: Conserving electricity is more essential due to the alarming depletion of the non-renewable sources of energy. It is necessary to conserve electricity to save the environment from global warming and other hazardous effects.

Complete answer:
Energy conservation is the process of reducing the overall usage of energy. With the growing technology and devices, there are a large number of ways to conserve electricity. Strategies can differ from person to person as some are able to do simply by using less energy when it comes to electricity, heating or cooling. In today's time, people have taken a more modern approach to safe energy with the help of energy-saving devices such as smart thermostats, efficient light bulbs and smart power strips.
Among the given options:
a. CFL requires less energy than other incandescent bulbs. It requires a tad more when it is turned on but then it uses 70% less electricity than regular bulbs.
b. The easy and quick method is to switch off lights and replace regular tube lights and bulbs with CFL and LED. Lights should be used only after dark, while fans run all day and night. Thus, fans contribute much more to power bills. While a tube light consumes around 55 watts per hour, an average fan consumes 75 watts. So switching them off when not in use will have a great impact.
c. Photovoltaic cells in a solar panel turn sunlight into direct electricity (DC). The sun is the largest source of energy and gives off far more energy than we'll ever need. It is also cost-effective.
Hence, the correct answer is option D.

Additional Information: Lightning occurs for a second but can create up to millions of volts of electricity. Electricity travels almost at the speed of light and is more than 186,000 miles per hour. Electricity is made when steam from boiling water makes huge wheels spin in a turbine in a power plant.

Note: Why is it important to conserve electricity?
a. It causes less pollution.
b. It reduces the use of fossils fuels to generate electricity.
c. It reduces the emission of free greenhouse gases.
