An underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, or silt) from which groundwater can be usefully extracted using a water well.

A thinly bedded shale that is rich in carbon, sulphide and organic material, formed by anaerobic (lacking oxygen) decay of organic matter. Black shales occur in thin beds in many areas at various depths and are of interest both historically and economically.

Carbon Capture and Storage (CCS) is a combination of a number of existing technologies, with the potential to play a major role in the management and reduction of global carbon dioxide (CO2) levels. The CCS process allows for CO2 emissions released during energy production to be captured and stored underground.

The EU’s goals for climate and energy in 2030, agreed upon in October 2014.

Conventional gas is natural gas that is produced by a well drilled into a geologic formation in which the reservoir and fluid characteristics permit the natural gas to readily flow to the wellbore.

The ratio of useful energy output versus the energy required to perform the process.

The European Commission's report outlining plans to ensure an affordable and secure energy supply.

On 15 December 2011, the European Commission adopted the Communication "Energy Roadmap 2050". The Roadmap outlines the EU's commitment to reducing greenhouse gas emissions to 80-95 per cent below 1990 levels by 2050 in the context of necessary reductions by developed countries as a group. In the Energy Roadmap 2050 the Commission exp [..]

A term used to refer to the reliability of future energy supply. This depends on a number of different factors, including the availability of energy supplies, their affordability, and the capacity to extract them in an environmentally sustainable manner.

Artificial ponds with very large surface areas that are designed to allow the efficient evaporation of water through exposure to sunlight and ambient surface temperatures.
