Alternative energy

Environmental Technologist

Apply theory and principles of environmental engineering to modify, test, and operate equipment and devices used in the prevention, control, and remediation of environmental problems, including waste treatment and site remediation, under the direction of engineering staff or scientist.

Over 2,300 years ago, a Greek philosopher named ______ first used the term "physics" to describe his study of collecting and classifying everything in the "physical" world.

Aristotle

Biotechnologist

Assist biological and medical scientists in laboratories. Set up, operate, and maintain laboratory instruments and equipment, monitor experiments, make observations, and calculate and record results. May analyze organic substances, such as blood, food, and drugs.

Physicist

Conduct research into physical phenomena, develop theories on the basis of observation and experiments, and devise methods to apply physical laws and theories.

Nuclear Scientists

Conduct research on nuclear engineering projects or apply principles and theory of nuclear science to problems concerned with release, control, and use of nuclear energy and nuclear waste disposal.

chemical engineer

Design chemical plant equipment and devise processes for manufacturing chemicals and products, such as gasoline, synthetic rubber, plastics, detergents, cement, paper, and pulp, by applying principles and technology of chemistry, physics, and engineering.

Design Engineer

Develop and design manufactured products, such as cars, home appliances, and children's toys

An external energy source must be applied for electrons to remain separated from their positively charged atoms.

False

This solar device converts the sun's energy into electricity.

Photovoltaic cell

_____ energy is the energy of position.

Potential

_____ is the rate of energy expended or generated over a specified amount of time.

Power

Electrical engineer

Research, design, develop, test, or supervise the manufacturing and installation of electrical equipment, components, or systems for commercial, industrial, military, or scientific use.

Geologists

Study the composition, structure, and other physical aspects of the Earth. May use geological, physics, and mathematics knowledge in exploration for oil, gas, minerals, or underground water; or in waste disposal, land reclamation, or other environmental problems.

Energy is the amount of force needed to do work.

True

Kinetic energy is the energy of motion

True

The migration of electrons from the P-layer leaves that layer with fewer electrons and, therefore, a highly positive charge.

True

Thermal energy that is stored in the world's oceans comes directly from the sun.

True

____ is accomplished when energy is used to move an object.

Work

In an electron-generating system, ________________ causes the separation of electrons from their atoms, creating positively charged atoms and free electrons.

an applied source of energy (force)

The chemical energy stored in ______________ was originally the sun's energy stored in prehistoric plants.

coal and petroleum

When a source of energy is applied to materials that conduct electricity, _____ are freed from their orbits.

electrons

The force that keeps atoms from flying apart is called ____.

energy

In a photovoltaic cell, the upper P-layer is usually treated or "doped" with a phosphorous material.

false

Kinetic energy is the energy of ______.

motion

The P-type layer of a PV cell has a _____ charge.

negative

The lower N-layer of the PV cell is "doped" with a ______ material.

phosphorus

The energy that ___________ carry is converted to some other form of energy in a circuit, such as heat, light, electromagnetic force, or radiation.

positive atoms

The atoms that lose electrons are left with "holes" where the electrons had been. These atoms then become _____ charged.

positively

A book resting on a table has _____ energy because someone lifted it and put it onto the table.

potential

All energy comes in two basic forms: kinetic energy and _____ energy.

potential

Most forms of alternative energy are actually forms of ______ energy.

solar

Thermal energy that is stored in the world's oceans comes directly from the sun.
