Energy 🏃♀️ Flashcards
Biomass
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 and methane.
Energy conservation
Reducing energy consumption through using less energy and becoming more
efficient in using existing energy sources.
Energy exploitation
Developing and using energy resources to the greatest possible advantage,
usually for profit.
Energy security
Uninterrupted availability of energy sources at an affordable price
Fossil fuel
A natural fuel such as coal or gas, formed in the geological past from the
remains of living organisms.
Geothermal energy
Energy generated by heat stored deep in the Earth.
Hydro(electric) power
Electricity generated by turbines that are driven by moving water.
Nuclear power
The energy released by a nuclear reaction, especially by fission or fusion.
Nuclear energy uses fuel made from mined and processed uranium to make
steam and generate electricity.
Renewable energy sources
A resource which is not diminished when it is used; it recurs and cannot be
exhausted (for example wind and tidal energy).
Solar energy
The Sun’s energy exploited by solar panels, collectors or cells to heat water or
air or to generate electricity.
Sustainable development
Development that meets the needs of the present without limiting the ability of
future generations to meet their own needs.
Sustainable energy supply
Energy that can potentially be used well into the future without harming future
generations. Sustainable energy is the combination of energy savings, energy
efficiency measures and technologies, as well as the use of renewable energy
sources.
Wind energy
Electrical energy obtained from harnessing the wind with windmills or wind
turbines.
