Energy

Question 1

Biomass

Answer 1

Renewable organic materials, such as wood, agricultural crops, or wastes, especially when used as a source of fuel or energy. biomass can be burned directly or processed into biofuels such as ethanol or methane

Question 2

Energy Conservation

Answer 2

Reducing energy consumption through using less energy and becoming more efficient in using existing energy sources

Question 3

Energy Exploitation

Answer 3

Developing and using energy resources to the greatest possible advantage usually for profit.

Question 4

Energy security

Answer 4

Uninterrupted availability of energy sources at an affordable price

Question 5

Fossil Fuel

Answer 5

A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms

Question 6

Geothermal Energy

Answer 6

Energy generated by heat stored deep in the Earth

Question 7

Energy Gap

Answer 7

An Energy Gap occurs when a country’s ability to supply energy to it’s citizens fall short of demand

Question 8

Hydro(electric) power

Answer 8

Electricity generated by turbines that are driven by moving water

Question 9

Solar Energy

Answer 9

The Sun’s energy exploited by solar panels, collectors or cells to heat water or air to generate electricity

Question 10

Sustainable Development

Answer 10

A Development that meets the needs of the present without limiting the ability of future generations to meet their own needs

Question 11

Nuclear Power

Answer 11

The energy released by nuclear reaction, especially by fission or fusion. The Nuclear Energy uses fuel made from mined and processed uranium to make steam and generate electricity.

Question 12

Renewable energy sources

Answer 12

A resource which is not diminished when it is used; it recurs and cannot be exhausted (at least on human timescales!). Includes wind power, tidal and wave power, solar power, and energy from Earth’s interior (geothermal).

Question 13

Non renewable Energy

Answer 13

This refers to sources of energy that are ‘finite’ and will eventually run out with continued use, because they are being extracted at a rate far higher than the rate at which they are replenished. Fossil fuels are a form of non-renewable energy. Nuclear power stations require the mining of uranium which is also a finite resource and therefore non-renewable.

Question 14

Sustainable Energy supply

Answer 14

Energy that can potentially be used well into the future without harming future generations. Sustainable energy is the combination of energy savings, energy efficient measures and technologies, as well as the use of renewable energy resources.

Question 15

Wind Energy

Answer 15

Electrical energy obtained from harnessing the wind with wind mils or wind turbines

Question 16

Global Warming

Answer 16

This term is usually used to refer to the warming of the Earth’s atmosphere that is currently taking place due to the human-caused increase in the atmospheric concentration of carbon dioxide and other ‘greenhouse gases’. This is mainly occurring due to the use of fossil fuels and to deforestation (i.e. humans cutting down and clearing large areas of forest).

Question 17

Greenhouse Gases

Answer 17

Gases in the atmosphere that have the effect of absorbing heat given off from the surface of the Earth, thereby slowing the escape of heat energy to space and causing the lower atmosphere to warm. Water vapour, carbon dioxide, and methane are important greenhouse gases.
