Renewable electricity production, from sources such as wind power and solar power, is sometimes criticized for being variable or intermittent. The International Energy Agency has stated that its significance depends on a range of factors, such as the penetration of the renewables concerned.
Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source ...
UN Secretary-General Ban Ki-moon Definitions The United Nations Brundtland Commission described the concept of sustainable development, for which energy is a key component, in its 1987 report Our Common Future. It defined sustainable development as meeting "the needs of the present without compromising the ability of future generations to meet their own needs". This description of sustainable ...
v. t. e. Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less energy for continuous service) or changing one's behavior to use less service (for example, by driving less). Energy conservation can be achieved through efficient energy ...
Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Climate change mitigation actions include conserving energy and replacing fossil fuels with clean energy sources. Secondary mitigation strategies include changes to land use and removing carbon dioxide (CO 2) from ...
Amory Bloch Lovins (born November 13, 1947) [2] is an American writer, physicist, [3] and former chairman/chief scientist of the Rocky Mountain Institute. [4] He has written on energy policy and related areas for four decades, and served on the US National Petroleum Council, an oil industry lobbying group, from 2011 to 2018.
Other limitations of the data include: a) missing life cycle phases, and, b) uncertainty as to where to define the cut-off point in the global warming potential of an energy source. The latter is important in assessing a combined electrical grid in the real world, rather than the established practice of simply assessing the energy source in ...
A renewable resource (also known as a flow resource[note 1][1]) is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale. When the recovery rate of resources is unlikely to ever exceed a ...
