Solar Absorbers and the Future of Electricity

What is the main focus of Jeff Chou's research at MIT?

• Developing new ways to convert solar energy into electricity

• Creating more efficient steam-powered machines

• Finding alternative fuels to replace coal and oil

• Improving the efficiency of electrical outlets

Why is solar power considered a renewable energy source?

• It does not consume its source when generating energy

• It is more efficient than coal and oil

• It can be used to power cars and toasters

• It is a new technology developed at MIT

What is the primary problem with using oil, gas, and coal for electricity?

• They are harmful to the Earth and are running out

• They are too expensive to produce

• They cannot generate enough electricity

• They are not available in the United States

What does Jeff Chou use to test his solar absorbers?

• A clean room with no germs or dirt

• A large outdoor solar farm

• A computer simulation

• A traditional laboratory with steam machines

What is the purpose of the solar absorbers Jeff is working on?

• To convert heat from the sun into electricity

• To store electricity for later use

• To replace electrical outlets

• To generate steam for power plants

What does Jeff Chou find exciting about his work with solar absorbers?

• They can potentially turn anything hot into electricity

• They are the most expensive form of energy

• They are easy to manufacture

• They can only be used in sunny climates

What is a significant benefit of solar energy according to Jeff Chou?

• It creates electrical energy without polluting the Earth

• It is cheaper than all other forms of energy

• It requires no maintenance

• It can be used to power only small devices

What kinds of energy does Jeff Chou work with?

• energy from coal, gas, and oil

• solar energy and energy from coal

• electrical energy and energy from oil

• solar energy and electrical energy

What does the passage describe?

• The passage describes electricity and the efforts of a scientist to turn solar energy into electricity.

• The passage describes the reasons that people from all over the world go to study at MIT.

• The passage describes what Jeff Chou does to keep the room where he does his experiments clean.

• The passage describes the few harmful byproducts that are created by people use energy from the sun.

Getting electricity from oil, gas, and coal pollutes the Earth.

What evidence from the passage supports this statement?

• Jeff Chou hopes that his panels will be sensitive enough to absorb electricity from anything hot, not just the sun.

• In order to generate steam for its electricity needs, the United States has to burn a lot of oil, gas, and coal.

• Using oil, gas, and coal burns toxic chemicals and releases them into the sky and the earth, which is harmful to people.

• According to Jeff Chou, testing your ideas to see whether or not they work is at the heart of science.
