Energy resources

Fossil fuels (coal, oil and gas) are the main energy resources used by humans. They are mostly burnt in power stations to produce electricity. Only a certain amount of these fuels exists, so they are known as non-renewable energy resources. Once used up they cannot be replaced as they take millions of years to form. Uranium, used as fuel in nuclear power stations is also a non-renewable energy resource.

Renewable energy resources are those which will not run out, or can be easily replenished. Examples are solar power, wind power, tidal power, hydroelectric power (from fast-flowing water), geothermal power (using the internal heat of the earth) and wood (trees grow quickly enough to replenish supplies).

There are a number of advantages and disadvantages to each of these energy resources.

- Non-renewable energy resources should be
used sparingly as they will not last for ever.

- Burning fossil fuels in power stations causes pollution. Sulphur dioxide (a cause of acid rain) and carbon dioxide (which increases the greenhouse effect) are produced. There is also concern that large-scale projects such as ‘wind farms’ (large groups of wind turbines) spoil the landscape.

- Some energy resources are more reliable than other: the sun and wind will not always be available when needed!

- Nuclear fuels must be treated very carefully as they are radioactive. Public opinion is often against their use, because of the risk of an accident. Nuclear power stations are relatively cheap to run, but very expensive to ‘decommission’ at the end of their lives to make them safe. Radioactive waste products are produced by nuclear power stations, and these are difficult to dispose of satisfactorily.

- The costs of resources vary. The sun, winds and tides are free, whereas fossil fuels must be mined. However, the equipment needed to harness the sun, winds and tides is expensive, as very large-scale projects are needed to generate as much electricity as one coal power station.

Electricity is the most convenient form of energy for us to use. It is generated in power stations.

In a traditional power station, fuel (coal/oil/gas) is burnt to heat water. The steam produced is used to turn turbines. The turbines drive the generators which produce electricity.

In nuclear power stations the heat from nuclear reactions heats the water, and in geothermal power stations water is pumped through hot rocks underground. In both cases the stream produced turns the turbines to drive the generators.

In other types of power station steam is not used. The turbines are turned directly by the wind, the flow of water downhill, or the water flowing out at low tide. The turbines then drive the generators in the same way.

Solar cells can be used to convert the sun’s energy directly to electricity. They are often used on satellites.

Electrical and electronics engineering

Electrical and electronics engineering is the largest and most diverse field of engineering. It is concerned with the development and design, application, and manufacture of systems and devices that use electric power and signals. Among the most important subjects in the field are electric power and machinery, electronic circuits, control systems, computer design, superconductors, solid-state electronics, medical imaging systems, robotics, lasers, radar, consumer electronics, and fibre optics.

Despite its diversity, electrical engineering can be divided into four main branches: electronic power and machinery, electronics, communications and control, and computers.

Electric power and machinery

The field of electric power is concerned with the design and operation of systems for generating, transmitting, and distributing electric power Engineers in this field have brought about several important developments since the late 1970s. One of these is the ability to transmit power at extremely high voltages in both the direct current (DC) and alternating current (AC) modes, reducing power losses proportionately. Another is the real-time control of power generation, transmission, and distribution, using computers to analyse the data fed back from the power system to a central station and thereby optimizing the efficiency of the system while it is in operation.

A significant advance in the engineering of electric machinery has been the introduction of electronic controls that enable AC motors to run at variable speeds by adjusting the frequency of the current fed into them. DC motors have also been made to run more efficiently this way.

Electronics

Electronic engineering deals with the research, design, integration, and application of circuits and devices used in the transmission and processing of information. Information is now generated, transmitted, received, and stored electronically on a scale unprecedented in history, and there is every indication that the explosive rate of growth in this field will continue unabated.

Electronic engineers design circuits to perform specific tasks, such as amplifying electronic signals, adding binary numbers, and demodulating radio signals to recover the information they carry. Circuits are also used to generate waveforms useful for synchronization and timing, as in television, and for correcting errors in digital information, as in telecommunications.

Prior to the 1960s, circuits consisted of separate electronic devices – resistors, capacitors, inductors, and vacuum tubes – assembled on a chassis and connected by wires to form a bulky package. The electronics revolution of the 1970s and 1980s set the trend towards integrating electronic devices on a single tiny chip of silicon or some other semiconductive material. The complex task of manufacturing these chips uses the most advanced technology, including computers, electron-beam lithography, micro-manipulators, ion-beam implantation, and ultraclean environments. Much of the research in electronics is directed towards creating even smaller chips, faster switching of components, and three-dimensional integrated circuits.

Communications and control

Engineers work on control systems ranging from the everyday, passenger-actuated, such as those that run a lift, to the exotic, such as systems for keeping spacecraft on course. Control systems are used extensively in aircraft and ships, in military fire-control systems, in power transmission and distribution, in automated manufacturing, and in robotics.
